Why Electrical Fault Finding Matters in WA

An electrical fault in a home announces itself in many ways: power that keeps tripping off, a circuit that has gone dead, lights that flicker, a switch that feels warm, or, more worryingly, a burning smell or a small shock from a tap or an appliance. Whatever the symptom, behind it is a cause, and electrical fault finding is the work of tracking that cause down so the problem can be properly and safely fixed.

Electrical fault finding matters first because of safety. Electricity is not a forgiving system, and some electrical faults are genuine fire and shock hazards. A fault that produces scorching, a burning smell, sparks or shocks is a warning that something is seriously wrong, and an electrical fault left undiagnosed and unaddressed can, at worst, lead to a fire or an electric shock. Finding the fault is not just about restoring convenience; it is about removing a hazard from the home before it causes harm.

Fault finding matters, too, because it is a genuine diagnostic skill. An electrical fault is often hidden, the cause is not obvious from the symptom, and an intermittent fault that comes and goes can be particularly hard to pin down. Locating a fault takes a licensed electrician working methodically, isolating circuits, testing systematically and using the right equipment to narrow down where the problem lies. Guessing at an electrical fault, or treating a symptom without finding the cause, does not resolve it and can leave a hazard in place.

There is one point that runs through this whole guide and cannot be overstated: all electrical work in Western Australia, including fault finding and any repair, must by law be carried out by a licensed electrician, and electrical work is never a do-it-yourself task. This guide explains the common faults, the diagnostic process, when a situation is urgent, and how to engage an electrician well, so a homeowner can understand what is happening and get it dealt with safely. Electrical fault finding is part of broader electrical services, and a fault in a home's electrical system is always a matter for a professional.

What Electrical Fault Finding Is

Electrical fault finding is a specific kind of electrical work, and understanding what it is, and how it differs from a straightforward installation or repair, helps a homeowner know what they are asking for and what to expect.

Fault finding is the diagnostic stage of dealing with an electrical problem. Where installing a new power point or light is a known, defined task, an electrical fault begins as a mystery: there is a symptom, the safety switch tripping, a dead circuit, flickering lights, but the cause is unknown. Fault finding is the investigative work of determining what is actually wrong, where, and why. It is the detective work that has to come before any repair, because a fault cannot be properly fixed until it has been correctly located and understood.

This diagnostic work is a real skill. An electrician finding a fault works methodically: gathering information about the symptom and when it occurs, isolating circuits to narrow down where the problem lies, using test equipment to measure and check, and reasoning from the evidence toward the cause. Some faults are found quickly; others, particularly intermittent ones that appear and disappear, take patient, systematic work to track down. The fault-finding process section later in this guide describes how this typically unfolds.

For a homeowner, the practical understanding is that fault finding and repair are two connected but distinct things. The electrician first finds the fault, then carries out, or advises on, the repair. Because the cause is unknown at the outset, fault finding is often charged for the diagnostic time rather than as a fixed price, and the repair is then separate, depending on what the fault turns out to be. Knowing this helps a homeowner understand how an electrician will approach and charge for the work, a point the quotes section returns to.

Common Electrical Faults

Electrical faults show themselves through a fairly recognisable set of symptoms, and knowing them helps a homeowner describe a problem to an electrician and understand how urgent it is. The sections that follow take the main ones in detail; this section is the overview.

The most common fault by far is a safety switch that keeps tripping, cutting the power and needing to be reset, sometimes repeatedly. Closely related is a circuit breaker that keeps tripping. A dead circuit, where part of the home has lost power while the rest is fine, is another common complaint. Lights that flicker, dim, or buzz are a frequent symptom, as are power points that have stopped working.

Other symptoms are more concerning and point more directly to a hazard. A burning or hot-plastic smell, scorch marks or discolouration around a switch, outlet or fitting, switches or outlets that feel hot to the touch, and buzzing, crackling or sizzling sounds from electrical fittings are all signs that something is seriously wrong. So are tingles or small shocks felt from an appliance, a tap or another metal fitting. These are not nuisance faults; they are warnings, and the burning smells, scorching, shocks and emergency sections of this guide explain why they should be treated as urgent.

For a homeowner, the practical point is to notice and note the symptom, including when and how it occurs, since that information helps the electrician, and to understand that while some faults are an inconvenience, others are a genuine safety hazard. Whatever the symptom, the response is the same in one respect: an electrical fault is a matter for a licensed electrician, and the more concerning symptoms warrant urgent attention. The sections that follow look at the main faults and their possible causes.

Why a Safety Switch Keeps Tripping

A safety switch that keeps tripping is the single most common electrical fault-finding call, and it is worth understanding properly, because the tripping is, in an important sense, the safety switch doing its job.

A safety switch, also called a residual current device or RCD, is a protective device that constantly monitors the electrical current and cuts the power very quickly if it detects the kind of imbalance that can occur when current is leaking to earth, the situation that can give a person a dangerous shock. So when a safety switch trips, it is responding to something: it has detected a fault condition and cut the power to protect people. A safety switch that keeps tripping is telling you there is a genuine fault somewhere that needs to be found.

The causes are several. A very common one is a single faulty appliance, since one appliance with an internal fault can be enough to trip the safety switch every time it is used, and this is why an electrician, or a homeowner, can sometimes narrow things down by isolating appliances. Other causes include moisture that has got into part of the wiring or a fitting, damaged or degraded wiring, a faulty switch, outlet or light fitting, or a fault within a circuit. The safety switch itself can also occasionally be the issue. Finding which of these it is, is exactly what fault finding does.

For a homeowner, the practical guidance is this: if a safety switch trips, it can be reset once, and if it holds and does not trip again, the event may have been a one-off. But if the safety switch keeps tripping, it should not simply be reset over and over, because it is repeatedly detecting a real fault, and that fault needs to be found and fixed by a licensed electrician. Repeatedly resetting a tripping safety switch, or worse, bypassing it, leaves a genuine hazard in place. The what-a-homeowner-can-safely-do section explains the limited, safe checks a homeowner can make.

Circuit Breakers and Overloads

Alongside the safety switch, a home's switchboard has circuit breakers, and a circuit breaker that keeps tripping is another common fault, with its own typical causes.

A circuit breaker protects an individual circuit against carrying too much current. When a circuit breaker trips, it has cut the power to its circuit because the current on that circuit has exceeded what it should be. Like the safety switch, the circuit breaker is a protective device doing its job, and a circuit breaker that keeps tripping is signalling a genuine problem on that circuit.

The causes fall into a couple of broad groups. One is overload: the circuit is simply being asked to carry more than it is designed for, for example because too many high-demand appliances are running on the same circuit at once. The other is a fault on the circuit itself, such as a fault in the wiring, a faulty appliance, or a faulty fitting, that is drawing excessive current. Distinguishing an overload from a circuit fault, and finding the specific cause, is part of what fault finding determines, and the right response, whether redistributing load, repairing a fault or, in some cases, addressing the circuit arrangement, depends on the cause.

For a homeowner, the practical guidance is similar to that for the safety switch: a circuit breaker can be reset, but a circuit breaker that keeps tripping should not simply be reset repeatedly, because it is responding to a real problem. The breaker should never be bypassed or interfered with, since it is a safety device protecting the circuit. A circuit breaker that keeps tripping is a matter for a licensed electrician to investigate, to determine whether it is an overload or a fault and to put it right safely.

Dead Circuits and No Power

A dead circuit, where part of the home has lost power while the rest is unaffected, is a common fault, and it has its own range of possible causes that fault finding works through.

The symptom is usually clear: a particular area or set of points and lights has no power, while the rest of the home is fine. Sometimes a dead circuit is simply a tripped circuit breaker or safety switch that has not been reset, which is the first thing to check at the switchboard. But where the protection has not tripped, or where it trips again immediately when reset, the dead circuit points to a fault: a fault in the wiring of that circuit, a loose or failed connection, a faulty fitting, or a problem at the switchboard. A dead circuit can also be caused by a fault that has interrupted the circuit somewhere along its length.

It is worth distinguishing a dead circuit, a fault within the home, from a loss of power to the whole property, which may be a wider supply issue rather than a fault in the home's wiring. A complete and sudden loss of power to the whole home, particularly if neighbouring properties are also affected, may be a network supply matter. A dead circuit affecting only part of the home, with the rest working normally, points to something within the home's own electrical installation, which is where fault finding comes in.

For a homeowner, the practical guidance is to check the switchboard first to see whether a breaker or safety switch has tripped, and if so to reset it once. If the circuit stays dead, or the protection trips again, the dead circuit is a fault to be found and repaired by a licensed electrician. A homeowner should not attempt to investigate the wiring of a dead circuit themselves, since that is electrical work, but noting which areas and points are affected helps the electrician locate the fault efficiently.

Flickering Lights and Dimming

Lights that flicker, dim unexpectedly, or behave oddly are a common complaint, and while the cause is sometimes minor, flickering can also point to a fault that warrants attention.

Flickering and dimming have a range of possible causes. At the simpler end, the cause can be the light itself, a globe or lamp that is failing, loose, or not well matched to its fitting or dimmer, and replacing a failing globe can resolve it. But flickering can also point to something more significant: a loose or deteriorating connection somewhere in the circuit, a fault in the wiring, an issue at a fitting or switch, or a problem affecting the circuit more broadly. Lights that dim when a large appliance starts up can indicate the load on a circuit, and widespread flickering across the home is more concerning than a single flickering light.

The reason flickering should not always be dismissed is that a loose or deteriorating electrical connection, which is one possible cause, is not just a nuisance: a poor connection can generate heat, and heat at a connection is a recognised fire risk. So while a single flickering light may turn out to be a simple globe issue, flickering that is persistent, widespread, or accompanied by any other symptom such as a warm fitting or a buzzing sound, should be taken seriously and investigated.

For a homeowner, the practical guidance is to note the pattern, which lights, how often, whether it coincides with anything, and to try the simple step of seeing whether replacing a suspect globe resolves a single flickering light. But persistent or widespread flickering, or flickering with any other symptom, is a matter for a licensed electrician to investigate through fault finding, since the cause may be a loose connection or a wiring fault that needs to be located and put right.

Burning Smells and Scorching

A burning smell, scorch marks, or discolouration around an electrical fitting is one of the most serious electrical warning signs, and it should never be ignored, because it points directly toward the risk of fire.

The signs to take seriously are a smell of burning or hot plastic with no obvious source, scorch marks, browning or discolouration around a power point, switch, light fitting or at the switchboard, switches or outlets that feel hot to the touch, and any visible melting or damage to a fitting. What these signs have in common is heat, electrical heat where there should not be any, and that heat is typically generated by a fault such as a loose or poor connection, an overloaded circuit or point, or damaged or deteriorated wiring or a fitting. Electrical heat of this kind is the mechanism behind electrical fires, which is why these signs are so serious.

Because of that fire risk, a burning smell or scorching is not a fault to leave until convenient; it should be treated as urgent. Where there is a clear sign of overheating or burning at a fitting, it is sensible to stop using that point or switch and, where the danger seems immediate, to switch off the power at the main switch on the switchboard if it is safe to reach. A licensed electrician should be contacted promptly, and where there are signs of an immediate fire risk, the emergency section of this guide explains the priorities. This is not an area for delay.

For a homeowner, the practical guidance is unambiguous: burning smells, scorching, discolouration and hot fittings are serious warning signs of a potential fire hazard, and they call for prompt action and a licensed electrician, not a wait-and-see approach. A homeowner should also ensure the home has working smoke alarms, which are a vital protection, and which connect to dedicated smoke alarm installation. Treating these warning signs with the seriousness they deserve can prevent a fire.

Shocks, Tingles and Buzzing

Feeling a shock or a tingle from an appliance, a tap or another metal fitting, or hearing buzzing or crackling from electrical fittings, are serious symptoms that point to a dangerous fault and should be acted on without delay.

A tingle or a small shock felt when touching an appliance, a metal tap, a metal fitting or another normally safe surface is a warning that electrical current is present where it should not be. This can indicate a fault such as a problem with the earthing, a fault in an appliance, or current leaking to a place it should not reach, and it is genuinely dangerous, because what is felt as a small tingle is electricity finding a path that, in the wrong circumstances, could deliver a serious or even fatal shock. A shock or tingle from any fitting should never be dismissed as a quirk to live with.

Buzzing, crackling, sizzling or humming sounds coming from a power point, switch, light fitting or the switchboard are similarly concerning. These sounds can indicate arcing or a poor connection, where electricity is jumping a gap or passing through a bad connection, and that produces heat and points toward both a shock and a fire risk. An electrical fitting should be silent in normal operation, so a buzzing or crackling fitting is signalling a fault.

For a homeowner, the practical guidance is to treat shocks, tingles and unusual sounds from electrical fittings as serious and urgent. Stop using an appliance or fitting that has given a shock or a tingle, avoid touching it, and where the danger seems immediate, switch off the power at the main switch if it is safe to do so. A licensed electrician should be contacted promptly, and a situation involving shocks is one where urgent attention is warranted. These symptoms are warnings of a dangerous fault, and the safe response is to keep clear and get a licensed electrician.

Common Causes of Electrical Faults

Behind the various symptoms lies a fairly consistent set of underlying causes, and understanding the common causes of electrical faults helps a homeowner appreciate what an electrician is looking for and why fault finding is needed.

A faulty appliance is one of the most common causes, and a single appliance with an internal fault can be responsible for a safety switch that keeps tripping, which is why isolating appliances is a useful diagnostic step. Damaged, degraded or deteriorating wiring is another major cause: wiring can be damaged physically, can deteriorate with age, and can be affected by heat, and aged wiring is covered in its own section. Faulty switches, outlets, light fittings and other components fail over time and cause faults at the point where they sit.

Moisture is a significant cause, since water reaching wiring or a fitting, through a leak, a storm, a damaged seal on an outdoor point, or condensation, can cause faults and is a common trigger for a tripping safety switch. Loose or poor connections are another important cause, and because a poor connection generates heat, they are behind many overheating and fire-risk situations. Overloaded circuits cause tripping breakers. And in Western Australia, two further causes are worth singling out: pests, since rodents in a roof space can damage wiring, and the effects of the WA environment, which the next sections cover.

For a homeowner, the practical understanding is that an electrical symptom can have any of several underlying causes, and that is precisely why fault finding is necessary: the symptom alone does not reveal the cause, and the cause has to be found before the right repair can be made. An electrician carrying out fault finding works through these possibilities methodically. The following two sections look at causes particularly relevant to Western Australian homes.

Moisture, Storms and Electrical Faults

Moisture is one of the most common causes of electrical faults, and the Western Australian weather, with its storms and seasonal rain, makes it a particularly relevant cause for WA homes.

Electricity and water do not mix, and moisture reaching a part of the electrical system where it should not be is a frequent cause of faults, especially a tripping safety switch, since moisture creates exactly the kind of current leakage a safety switch is designed to detect. Moisture can reach the electrical system in several ways: a roof leak letting water into the roof space where wiring runs, water getting into an outdoor power point or fitting whose seal has failed, rain driven into an inadequately protected external fitting, or moisture affecting a fitting in a damp area.

Western Australian weather brings this to the fore. The state experiences storms, the summer can bring intense thunderstorms, and the cooler months bring rain and winter storms, particularly in the south-west. Heavy rain and storms can drive water into places it does not normally reach, can cause or reveal roof leaks, and the storm season is a recognised time for moisture-related electrical faults to appear. Storms also bring lightning and the power surges associated with it, which can damage electrical equipment and is part of why surge protection is worth considering, connecting to surge protection and lightning protection installation.

For a homeowner, the practical points are that a fault appearing during or after a period of wet weather may well be moisture-related, that this is useful information to give an electrician, and that keeping the home weathertight, with a sound roof and properly sealed external fittings, helps prevent moisture faults. A safety switch tripping after rain is a common WA scenario, and it is a matter for a licensed electrician to find and address the moisture-affected part of the system safely.

Ageing Wiring and Old Switchboards

The age of a home's electrical installation is a real factor in electrical faults, and Western Australia has many older homes whose wiring and switchboards reflect the standards and materials of an earlier time.

Electrical wiring and components do not last forever. Over decades, wiring can deteriorate, insulation can age and become brittle, connections can loosen, and components can wear out, and an older home may have wiring that is simply reaching the end of its serviceable life. An older home is therefore more prone to electrical faults arising from deteriorated wiring and aged components, and a pattern of recurring faults in an older home can sometimes point to an installation that is aged overall rather than to a single isolated fault.

Old switchboards are a related issue. An older home may still have an original switchboard with old-style fuses rather than modern circuit breakers, and, importantly, an old switchboard may not have safety switches, the RCDs that provide essential shock protection. A switchboard of this kind is both less convenient and less safe than a modern one, and fault finding in an older home sometimes reveals that the switchboard itself is outdated and would benefit from an upgrade. Switchboard upgrades have their own section later in this guide and connect to dedicated switchboard upgrade work.

For a homeowner with an older WA home, the practical guidance is to be aware that ageing wiring and an old switchboard can be the underlying reason for electrical faults, and that an electrician doing fault finding may identify the age and condition of the installation as a factor. Where that is the case, the electrician can advise on what is needed, which may range from a specific repair to a switchboard upgrade or the rewiring of part of the home. An electrical safety inspection, covered later, is a good way to understand the condition of an older home's electrical system.

The Fault Finding Process

Electrical fault finding follows a methodical process, and understanding how a licensed electrician typically approaches it helps a homeowner know what to expect and why fault finding is a genuine diagnostic task.

The process begins with information. The electrician asks about the symptom, what is happening, where, how often, when it started, and whether anything coincides with it, such as wet weather or a particular appliance. This information narrows the field from the outset. The electrician then inspects the relevant parts of the system, starting often at the switchboard, and looks for any obvious signs, scorching, damage, moisture, that point toward the cause.

From there the electrician works systematically to isolate the fault. This typically means dividing the problem down: isolating circuits one at a time to determine which circuit the fault is on, isolating appliances to see whether a single appliance is responsible, and using electrical test equipment to measure and check the system and confirm where the fault lies. A clear, repeatable fault is generally located reasonably quickly by this systematic narrowing. An intermittent fault, one that comes and goes, is harder, since it may not be present when the electrician is there, and tracking it down can take more time and patience.

Once the fault is found, the electrician can explain what is wrong and what the repair involves, and carry out or arrange that repair. For a homeowner, the practical understanding from this is twofold. First, fault finding is real diagnostic work, and because the time it takes depends on how hidden or intermittent the fault is, it is often charged for the time rather than as a fixed price. Second, a methodical electrician who works through the system properly is far more likely to find the true cause than one who guesses, which is why the approach matters as much as the price.

Licensing and Why Only Licensed Electricians

This is the most important section in the guide, because it concerns a rule that protects lives: all electrical work in Western Australia, including fault finding and any repair, must be carried out by a licensed electrician.

Electrical work in WA is regulated, and the law requires that it be done by a licensed electrician. This is not a formality or red tape; it exists because electricity is genuinely dangerous. Working on a home's electrical system carries a real risk of electric shock, which can be fatal, and incorrect electrical work can leave behind a hazard, a fire risk or a shock risk, that endangers the household for as long as it remains. A licensed electrician has the training, the knowledge of the wiring rules and the competence to work on the system safely and correctly. Electrical work done by an unlicensed person is both unlawful and dangerous.

This rule applies fully to fault finding and fault repair. Diagnosing an electrical fault means working with the live electrical system, and repairing a fault means working on the wiring, the switchboard or the fittings, and both are electrical work that the law requires to be done by a licensed electrician. There is no version of electrical fault finding or repair that is appropriate for a homeowner or an unlicensed person to undertake. A homeowner who attempts to investigate or fix an electrical fault themselves risks a serious or fatal shock and risks leaving a hazard in the home.

For a homeowner, the guidance is absolute: an electrical fault is always a matter for a licensed electrician, and electrical work is never a do-it-yourself job. The what-a-homeowner-can-safely-do section sets out the few genuinely safe things a homeowner can do, which are limited to non-invasive checks, and everything beyond that is for a licensed electrician. A homeowner should always confirm that the person doing electrical work holds a current electrician's licence. Electrical licensing and safety in WA are overseen by Building and Energy, with information available from EnergySafety and DMIRS.

When It Is an Emergency

Not every electrical fault is an emergency, but some genuinely are, and knowing the difference helps a homeowner respond appropriately, calling for urgent help when the situation truly calls for it.

Certain signs point to an immediate hazard and should be treated as an emergency. These include any sign of electrical fire or imminent fire risk, such as smoke, flames, or serious scorching and burning at a fitting; sparks coming from a power point, switch or fitting; a strong, persistent burning smell with no other explanation; anyone receiving an electric shock; and exposed or seriously damaged wiring. In these situations the priority is safety: if it is safe to do so, switch off the power at the main switch on the switchboard, keep people away from the hazard, and in the case of any fire that cannot be immediately and safely dealt with, treat it as a fire emergency and call the emergency services. An emergency electrician should be contacted for an urgent electrical hazard.

Other faults are serious and warrant prompt attention, though not necessarily a middle-of-the-night call-out. A safety switch that keeps tripping and leaving the home without power, a burning smell or hot fitting that is not actively flaming, or shocks and tingles, are situations to address promptly with a licensed electrician rather than to live with. And some faults, a single flickering light, a dead circuit that is not accompanied by any concerning sign, are an inconvenience to be dealt with in the normal course rather than an emergency.

For a homeowner, the practical guidance is to judge the urgency by the signs of immediate danger. Fire, smoke, sparks, shocks and the smell of active burning mean an emergency response: make people safe, switch off the power at the main switch if it can be done safely, and get urgent help, treating any fire as a fire emergency. Serious but non-immediate faults warrant a prompt call to a licensed electrician, and emergency electrical help is available, connecting to dedicated emergency electrician services. When in doubt about safety, the cautious course, keeping clear and getting professional help, is always the right one.

What a Homeowner Can Safely Do

While electrical work is strictly for licensed electricians, there are a few genuinely safe, non-invasive things a homeowner can do when an electrical fault occurs, and it is worth being clear about both what those are and where the firm line lies.

The safe actions are limited and non-invasive. A homeowner can observe and note the symptom, what is happening, where, when it started, how often, and whether it coincides with anything such as wet weather or a particular appliance, since this information genuinely helps an electrician. A homeowner can look at the switchboard to see whether a circuit breaker or safety switch has tripped, and can reset a tripped breaker or safety switch once by switching it back on. A homeowner can also, in the case of a tripping safety switch, carry out the simple, non-invasive check of unplugging appliances to see whether a single faulty appliance is the cause, since this involves only the appliance plugs, not the electrical installation itself. And in a clear emergency, a homeowner can switch off the power at the main switch if it is safe to reach.

The firm line is everything beyond that. A homeowner should not open up or remove power points, switches, light fittings or any part of the switchboard; should not touch, investigate or attempt to repair wiring; should not attempt to fix a fault; and should never bypass, disable or interfere with a safety switch or circuit breaker. A safety switch that keeps tripping should not be repeatedly reset in an endless cycle, and it must never be bypassed, because doing so removes essential shock protection. All of this is electrical work, and all of it is for a licensed electrician.

For a homeowner, the practical summary is simple: observe and note the symptom, check and reset the switchboard once, try unplugging appliances to isolate a faulty one, and switch off at the main switch in an emergency, but go no further. Everything else is for a licensed electrician. Knowing this limited safe role lets a homeowner be genuinely helpful, by giving the electrician good information and perhaps narrowing down a faulty appliance, without ever putting themselves at risk or leaving a hazard in the home.

RCDs and WA Requirements

Safety switches, properly called residual current devices or RCDs, are central to electrical safety in Western Australian homes, and there are requirements in WA relating to them that a homeowner should understand.

An RCD is a protective device that monitors the electrical current and cuts the power very quickly if it detects the kind of current leakage that occurs when electricity finds an unintended path, such as through a person. By cutting the power in a fraction of a second, an RCD provides vital protection against electric shock, and it is one of the most important safety devices in a home's electrical system. The RCD is the device that trips, as discussed earlier, when it detects a fault, and that tripping, while inconvenient, is the RCD doing exactly what it is there to do.

Western Australia has requirements relating to RCDs in homes. WA regulations require RCD protection in residential premises, and these requirements are notably engaged when a home is sold or when it is leased to tenants, with the result that RCDs are required to be fitted. The intent is straightforward: to ensure homes have the shock protection that RCDs provide. An older home that has not had RCDs fitted, perhaps with an original switchboard, is both less safe and likely not to meet these requirements, which is one of the reasons fault finding in an older home can lead to a discussion about the switchboard.

For a homeowner, the practical points are several. RCDs are an essential safety feature, and a home should have them. WA has requirements for RCDs, particularly relevant when buying, selling or leasing a property, so a homeowner in any of those situations should ensure the position is understood and addressed by a licensed electrician. And RCDs themselves can be tested: most have a test button that, when pressed, should cause the RCD to trip, confirming it is working, and testing RCDs periodically in this simple way is good practice. Where a home lacks RCDs or has an outdated switchboard, a licensed electrician can advise, and the current requirements can be confirmed through Consumer Protection WA and EnergySafety.

Switchboard Upgrades and Repairs

Fault finding sometimes leads to the switchboard, and a homeowner should understand why an older switchboard can be part of the problem and what a switchboard upgrade involves.

The switchboard is the heart of a home's electrical system, the point where the supply is distributed to the circuits and where the protective devices, the circuit breakers and safety switches, sit. An older switchboard can fall short in several ways. It may still use old-style ceramic fuses rather than modern circuit breakers, it may lack safety switches and therefore lack the essential shock protection RCDs provide, it may have deteriorated with age, and it may simply not have the capacity or arrangement to suit a modern home's electrical demands. An electrician carrying out fault finding may identify the switchboard itself as outdated, unsafe, or a contributing factor to recurring faults.

A switchboard upgrade replaces an outdated switchboard with a modern one. A modern switchboard has circuit breakers protecting the circuits, has safety switches providing RCD protection, is arranged to suit the home, and is safer and more reliable than an old fuse board. A switchboard upgrade is genuine electrical work, carried out by a licensed electrician, and it is one of the more worthwhile electrical improvements for an older home, both for safety, because of the RCD protection, and because it brings the heart of the electrical system up to a modern standard. Switchboard work is covered by dedicated switchboard upgrade services.

For a homeowner, the practical point is that if fault finding identifies the switchboard as outdated or unsafe, an upgrade is a sensible investment rather than an unwelcome upsell, particularly where the old board lacks safety switches. A good electrician will explain clearly why a switchboard upgrade is being recommended and what it involves, so the homeowner can understand the reasoning. For an older WA home, bringing the switchboard up to a modern standard, with proper RCD protection, is a genuine safety improvement.

Electrical Safety Inspections

Beyond responding to a specific fault, a homeowner can have the whole electrical system checked through an electrical safety inspection, and it is worth understanding the value of this, particularly for older homes.

An electrical safety inspection is a check of a home's electrical installation by a licensed electrician, looking at the condition and safety of the wiring, the switchboard, the safety switches, the fittings and the overall system. Where fault finding is reactive, responding to a problem that has already appeared, a safety inspection is proactive, assessing the system as a whole to identify any issues, hazards or deficiencies before they cause a fault or an incident. It gives a homeowner a clear picture of the condition and safety of their electrical system.

An electrical safety inspection is particularly worthwhile in several situations: when buying a home, to understand the condition of its electrical system before committing; for an older home, where the age of the wiring and switchboard makes a check sensible; for a home that has had recurring electrical problems, to assess whether there is an underlying issue; and periodically for any home, as a general check on safety. An inspection can confirm that the system has proper RCD protection, identify ageing or deteriorated wiring, and flag anything that needs attention.

For a homeowner, the practical guidance is that an electrical safety inspection is a sensible way to gain peace of mind and to catch problems early, especially for an older home or one being bought. It complements fault finding: fault finding deals with a problem that has appeared, while an inspection looks for problems before they do. A dedicated electrical safety inspection service covers this, and for an older WA home in particular, an inspection is a worthwhile step toward keeping the home electrically safe.

Preventing Electrical Faults

While not every electrical fault can be prevented, a homeowner can do a number of things to reduce the likelihood of faults and to keep a home's electrical system safe and reliable.

Several sensible habits help. Testing the safety switches periodically using their test buttons confirms they are working and providing protection. Not overloading circuits and power points, in particular avoiding running many high-demand appliances from one outlet through piggybacked adaptors, reduces overload faults. Keeping appliances in good condition and replacing or repairing faulty ones promptly removes a common cause of tripping safety switches. Keeping the home weathertight, with a sound roof and properly sealed external fittings, helps prevent the moisture faults that WA weather can cause. And being alert to early warning signs, a fitting that has started to feel warm, an occasional flicker, a faint smell, and acting on them, catches problems before they grow.

Keeping the electrical system itself in good order matters too. For an older home, ensuring the system has proper RCD protection and considering a switchboard upgrade where the board is outdated addresses a fundamental safety gap. Having an electrical safety inspection, particularly for an older home or one with a history of problems, identifies issues proactively. And having any electrical work that is done, whether a repair, an addition or an upgrade, carried out properly by a licensed electrician ensures the system is not compromised by poor work.

For a homeowner, the practical approach is a combination of sensible habits, testing the safety switches, not overloading circuits, looking after appliances, keeping the home weathertight, watching for early warning signs, and keeping the electrical system in good condition through proper RCD protection, a sound switchboard, and licensed work. None of this guarantees against every fault, but it genuinely reduces the likelihood of faults and helps keep the home electrically safe. When a fault does occur despite this, it is, as always, a matter for a licensed electrician.

Strata and Rental Properties

Electrical faults in strata properties and rental homes involve some questions of responsibility, and it is worth understanding them, since the response to a fault is not always solely the occupier's to arrange.

In a rental property, electrical faults are generally a matter for the owner or property manager rather than the tenant, since the electrical system is part of the property and its safety and maintenance are the owner's responsibility. A tenant who experiences an electrical fault should report it to the owner or property manager, and a fault that involves any safety concern, such as a burning smell, scorching, sparks or shocks, should be reported promptly and treated seriously. The owner is responsible for arranging a licensed electrician, and electrical safety in a rental, including proper RCD protection, is an important matter. A tenant should not attempt to deal with an electrical fault themselves.

In a strata property, the picture depends on where the fault lies. Faults within the individual lot's electrical system are generally the lot owner's concern, while faults involving the common property or the building's shared electrical infrastructure are a matter for the owners corporation. Where it is unclear whether a fault sits within the lot or the common property, the strata company can clarify, and the Strata Titles Act 1985 provides the framework in WA. In all cases, the actual fault-finding and repair work must be done by a licensed electrician.

For a tenant or a strata resident, the practical guidance is to report electrical faults through the proper channels, the owner or property manager for a rental, the strata company where common property may be involved, and to do so promptly, particularly where there is any safety concern. The diagnostic and repair work itself is for a licensed electrician regardless of the property type. Information on tenancy matters is available from Consumer Protection WA, and a safety-related electrical fault should never be left unreported because of uncertainty over responsibility.

What to Look Out For

Choosing the right electrician for fault finding matters, and there are clear things to look for and to be wary of. The first and most fundamental is licensing: the electrician must hold a current electrician's licence, since all electrical work in WA must be done by a licensed electrician, and a homeowner should never engage anyone unlicensed for electrical work, whatever the apparent saving. This is non-negotiable and is a safety matter.

On pricing, it is worth understanding how fault finding is charged. Because the cause of a fault is unknown until it is found, fault finding is often charged for the diagnostic time, typically a call-out fee plus an hourly or time-based rate, rather than as a fixed price, and a homeowner should expect this and ask the electrician to explain their charging basis upfront. A quote that promises a fixed price to fix a fault that has not yet been diagnosed should be treated with some caution, since the repair cannot be known before the fault is found. An honest electrician explains the charging clearly and keeps the homeowner informed as the work proceeds.

Be wary, too, of an electrician who appears to guess rather than diagnose, who proposes a significant repair, or a major job such as rewiring, without methodically establishing the cause, or who is vague about what the fault actually is. Good fault finding is methodical, and a good electrician can explain what they found, why, and what the repair addresses. Equally, where an electrician does identify a genuine underlying issue, such as an unsafe switchboard or deteriorated wiring, that is honest advice rather than an upsell, and a good electrician explains the reasoning so the homeowner can understand and decide.

Watch for the usual signs of a contractor to avoid: no evidence of a current licence, no insurance, vagueness about the charging or the work, reluctance to explain what was found, pressure toward a large job without clear diagnosis, or a demand for a large payment upfront. The signs of a good fault-finding electrician are consistent: a current electrician's licence, a clear explanation of the charging basis, a methodical diagnostic approach, a clear account of what the fault was and what the repair addresses, honest advice on any underlying issues, evidence of insurance, and a straightforward, professional manner.

How to Get Useful Quotes

Getting useful quotes for electrical fault finding starts with describing the problem as clearly as possible. The brief should set out the symptom, a tripping safety switch, a dead circuit, flickering lights, a burning smell, and as much detail as possible: where it occurs, when it started, how often it happens, whether it is constant or intermittent, and whether it coincides with anything such as wet weather or the use of a particular appliance. Good detail genuinely helps an electrician understand the likely nature of the fault.

It is important to understand that fault finding is quoted differently from a defined job. Where installing a known item can be quoted as a fixed price, fault finding cannot, because the cause and therefore the repair are unknown until the fault is found. What an electrician can tell a homeowner upfront is their charging basis, the call-out fee and the hourly or time-based rate for the diagnostic work, and a homeowner should ask for and understand this. The repair cost then follows once the fault is diagnosed, and a good electrician will explain what the repair involves and what it will cost before carrying it out.

Where a fault is clearly an emergency, involving fire risk, sparks, shocks or a serious hazard, the priority is getting a licensed electrician promptly rather than gathering multiple quotes, and an emergency electrician can attend urgently. For a non-urgent fault, a homeowner can reasonably contact more than one licensed electrician to understand the charging basis, while bearing in mind that the genuine comparison is the diagnostic rate and the electrician's competence and approach, not a fixed total that cannot honestly be given before the fault is found.

Confirm that any electrician engaged holds a current electrician's licence and carries appropriate insurance, and ask about their charging basis for fault finding and their experience with the kind of fault involved. Posting a clear description of the problem through The Quote Yard is an efficient way to reach licensed WA electricians and have the fault attended to, and where fault finding leads to wider work the description can take in related services such as a switchboard upgrade or an electrical safety inspection.

Insurance and Your Rights

Electrical fault finding is important safety work, and it is worth understanding the protections and your rights, since they give a homeowner solid footing and reinforce why licensed work matters.

Licensing is the foundation. A licensed electrician has the training and competence to work safely and correctly on a home's electrical system, and the licensing requirement exists precisely because electrical work carries genuine risk. Using a licensed electrician is both a legal requirement and the homeowner's basic assurance that the fault finding and repair are done properly. A homeowner is entitled to confirm that an electrician holds a current licence, and should always do so. A professional electrician should also carry public liability insurance, covering damage they might accidentally cause or injury arising from their work, and a homeowner can ask about this too.

Properly done electrical work also matters for a homeowner's own insurance. Home and contents insurance policies generally expect that a home's electrical work has been done lawfully and competently, and electrical work carried out by an unlicensed person, or done improperly, could affect a claim, particularly a claim relating to an electrical fire. Having electrical work done by a licensed electrician, and keeping the documentation, is therefore part of protecting the home's insurance position as well as the household's safety. Where an electrical fault has caused damage, a homeowner should check their policy and report it appropriately.

Consumer rights apply to the work. Under the Australian Consumer Law, electrical work as a service must be carried out with due care and skill, and any goods supplied, such as switchboard components or fittings, come with guarantees that they are of acceptable quality and fit for purpose, so a homeowner who receives clearly substandard work has rights. A licensed electrician's work also typically carries a workmanship warranty. Information on consumer rights is available from Consumer Protection WA and the ACCC.

Electrical licensing and safety in WA are overseen by Building and Energy, with information available from EnergySafety and DMIRS, the wiring rules and electrical standards are published by Standards Australia, and general fire safety information, relevant given the fire risk some electrical faults carry, is available from the Department of Fire and Emergency Services. A homeowner who engages a licensed, insured electrician, has electrical faults diagnosed and repaired properly, keeps the home's electrical system in good order with proper RCD protection, and keeps the paperwork has both a safe home and solid footing should any question arise.
