ELECTRICAL FAULTS WE FIND & REPAIR
POWER LOSS & DE-ENERGISED CIRCUITS
Losing power doesn't always mean your entire property goes dark. A fault may affect a single power point, a group of lights, one circuit, part of the house or the whole installation.
Sometimes the problem is constant; other times the power disappears only when particular equipment is operating or under certain conditions.
The cause can sit in several different parts of the electrical system, so replacing the first component that appears suspicious isn't proper fault finding. The problem may involve a protective device, damaged or deteriorated wiring, a loose connection, faulty equipment, an overloaded circuit or another issue elsewhere on the circuit.
Fault finding involves working through the installation methodically. We use the symptoms, circuit behaviour and electrical testing to narrow down where the problem is occurring and identify the underlying cause.
Once we've established what has failed and why, we can explain the findings and determine the appropriate repair.
Where the fault can be repaired during the visit, we'll discuss the work with you and get it sorted. If further work, replacement equipment or a larger repair is required, you'll know what we've found and what needs to happen next.
SAFETY SWITCHES THAT KEEP TRIPPING
A safety switch or circuit breaker that trips once may be responding exactly as it should. When it keeps tripping, won’t reset, or trips again as soon as particular equipment is used, there is usually a reason that needs to be identified rather than repeatedly resetting the switch.
The cause isn’t always the switch itself. Repeated tripping can be associated with a faulty appliance, damaged wiring, moisture, deterioration, an overloaded circuit or a fault elsewhere in the installation. Different protective devices also perform different jobs, which is why understanding exactly what is tripping — and under what circumstances — is an important part of the diagnosis.
Fault finding starts by establishing which circuit is affected and what was happening when the trip occurred. Electrical testing can then be used to progressively narrow down the circuit, equipment or part of the installation responsible for the fault rather than replacing components on suspicion.
Once the cause has been identified, we can explain what has happened and determine the appropriate repair. That may be relatively straightforward, or the testing may uncover an issue elsewhere in the circuit that needs attention.
Either way, the objective is the same: find the reason it is tripping, repair the underlying fault and verify the circuit is operating correctly before we leave.
FLICKERING, DIMMING & UNSTABLE LIGHTING
Lights that flicker, pulse, dim unexpectedly or change brightness can indicate anything from a failing LED driver or light fitting to loose connections, damaged wiring, switching faults or problems elsewhere in the electrical installation. Whether it affects one light or several, happens constantly or intermittently, or changes when other equipment operates can provide important clues about the cause.
Not every flickering-light problem originates inside the property. Ripple-control signals used by the electricity network can interact with some LED lighting equipment, causing noticeable flickering or disturbances at particular times. Where the timing and symptoms suggest ripple interference, we can investigate the installation and, where appropriate, install suitable filtering equipment to reduce its effect.
Another possibility is capacitive coupling. Cables running alongside each other can transfer a very small amount of electrical energy between conductors. Because modern LEDs require very little energy, this can sometimes cause an LED to faintly glow, pulse or flash even when switched off.
Proper fault finding means looking at when the problem occurs, which lights are affected, whether they’re switched on or off, what other equipment is operating and whether there is a repeatable pattern. Electrical testing can then help distinguish between equipment failure, connection or circuit faults, capacitive coupling and network-related interference. The aim isn’t simply to stop the flicker — it’s to identify the cause and apply the right solution.
FAULTY POWER POINTS, SWITCHES & ELECTRICAL FITTINGS
Power points and switches are used constantly, and faults can appear in different ways — an outlet that has stopped working, a switch that feels loose or operates intermittently, plugs that no longer sit firmly, visible discolouration, unusual noises or excessive heat around a fitting. Sometimes one fitting is affected; other times the problem is further back in the circuit.
A failed power point or switch isn't necessarily just a worn fitting that needs replacing. The cause may be a loose or deteriorated connection, damaged terminal, heat damage, faulty equipment, deteriorated wiring or another problem elsewhere on the circuit. Heat and discolouration are particularly important symptoms because poor electrical connections can generate additional heat under load and progressively damage the fitting and surrounding conductors.
Proper diagnosis means looking beyond the visible component. We assess the condition of the fitting and associated wiring, consider the equipment and electrical load connected to the circuit, and carry out appropriate electrical testing to determine whether the fault is isolated to that point or forms part of a wider circuit problem.
Once the cause is known, we can repair or replace the affected equipment and address any underlying wiring or connection issue discovered during testing. Simply replacing a damaged power point without understanding why it failed can leave the actual cause untouched. Our objective is to repair the fault, verify the circuit and leave the installation operating safely and correctly.
