Electrics Keep Tripping? Fault-Finding in Kent

Why electrics trip in the first place

Tripping is your electrics protecting you. A breaker or RCD switches off because it has detected something it’s designed to act on: too much current, or current leaking where it shouldn’t. So a circuit that keeps tripping isn’t being awkward, it’s reporting a fault. The job is to find what it’s reporting rather than just resetting it over and over, which stresses the installation and tells you nothing. We trace tripping faults across Kent.

The pattern usually tells the story: what trips, how often, and what you were doing at the time. We use that to narrow things down fast, often before we’ve even arrived.

RCD tripping vs breaker tripping

The two main devices trip for different reasons. A circuit breaker (MCB) trips on too much current, an overload or a short circuit. An RCD trips on a small leakage of current to earth, which is the classic sign of damaged cable, water ingress, or a failing appliance.

Knowing which one is tripping points us straight at the type of fault. RCD trips tend to mean insulation or moisture problems, breaker trips tend to mean overload or a dead short. We confirm which on site and follow the evidence.

Finding the fault without guesswork

Proper fault-finding is a process, not a guess. We split the installation down, isolate circuits, and test each one to see which is leaking or shorting. Where an appliance is the culprit, we identify it so you can repair or replace it. Where it’s the fixed wiring, an accessory, a buried cable, or water in a fitting, we locate it and quote the fix.

The most common causes we find are failing RCDs at the end of their life, water in outdoor or bathroom fittings, damaged cables (often from a nail or a screw), and faulty appliances dragging a circuit down.

Nuisance tripping and old boards

Some tripping isn’t a single dramatic fault but “nuisance tripping”, where an older or shared RCD trips on the combined small leakages of several circuits that are each individually fine. It’s maddening because nothing seems broken.

The cure is often to split the load across separate protective devices, which is exactly what a modern board with individual RCBOs does. If that’s the diagnosis, see consumer unit replacement, and we’ll explain whether it applies to your installation.

How we trace a tripping fault

Tell us what trips, how often, and what you were doing when it happens. We’ll often triage on the phone first, because if it’s one appliance you can isolate, you may not need a visit at all. On site we test methodically to split the circuits and find the fault, make the installation safe, and quote the repair before carrying it out.
