Common faults we are called out to
- RCDs or RCBOs that trip at random, or when the washing machine starts its spin
- A circuit that works until a specific appliance is plugged in
- One or two sockets that have gone dead while the rest of the ring is fine
- Lights that dim or flicker on one circuit
- A smell of burnt plastic near a socket or ceiling rose
- Full-house power loss with breaker that will not reset
How we work through it
A proper fault-find is insulation resistance testing, continuity testing and a look through junction boxes, ceiling roses and sockets. We split the circuit where it makes sense rather than ripping walls apart. Nine times out of ten the cause is a loose terminal, a damp ingress, or an appliance with a failing element — all fixable without a rewire.
When to stop and call
If you see sparks, smell burning, or a breaker will not reset and is warm to the touch, isolate at the main switch and call straight away. Do not keep pushing the breaker back on — that can turn a small fault into a dangerous one.
