Switchboards & safety switches
Nuisance trips, dead circuits, and board faults.
Safety switch (RCD) keeps tripping at the switchboard
The safety switch trips repeatedly — instantly on reset, randomly, or when certain appliances run. It's detecting earth leakage somewhere; the job is to find where.
Safety switch won't reset
The safety switch won't stay up when you try to reset it — power can't be restored because a fault is still present (or the device/wiring is at fault).
A circuit breaker keeps tripping (domestic)
One circuit breaker keeps tripping — instantly on reset or after a load runs — and you need to tell an overload from a short or a faulty appliance.
No power to the whole house
The entire home has no power — nothing works. Could be a supply outage, the main switch/main safety switch, or a main fault, and the first job is to tell which.
Switchboard buzzing, warm, or smells hot
The switchboard hums/buzzes, feels warm, or has a hot/burning smell — a sign of a loose connection or an overloaded device, and a genuine fire-risk warning.
Old rewireable fuse blowing repeatedly
An older home with ceramic rewireable fuses keeps blowing a fuse on one circuit — the fuse is doing its job; something is overloading or faulting that circuit.
