Why do my electrics keep tripping?

A protective device is doing a job

A circuit breaker or residual current device (RCD) switches off a supply when it detects certain unsafe conditions. Repeated tripping can be associated with an appliance or the fixed wiring and needs investigation.

Do not keep resetting the switch

Leave a repeatedly tripping circuit off and arrange an electrician. Never hold a switch in position, bypass protection, replace a fuse with a higher rating or remove consumer-unit covers.

If you noticed a particular appliance immediately before the trip, stop using it. Unplug it only if the plug and socket are dry, undamaged and safe to approach. Do not try the suspect appliance in another socket.

Useful details for fault finding

• Which labelled switch trips, and which areas lose power?
• Did an appliance start, or had anything new been plugged in?
• Does it coincide with rain or equipment outdoors?
• Have there been leaks, recent alterations or visible damage?

Record what you have already observed; do not deliberately recreate a fault. An electrician can use these details to plan the investigation.

Warning signs need urgent attention

Keep away from wet or damaged equipment. For smoke, fire or immediate danger, get clear and call 999. For repeated tripping without an immediate emergency, see our electrical fault-finding service.
