Why Does My Fuse Box Keep Tripping?

Updated 5 August 2026

Tripping is a safety feature

Your consumer unit trips to protect you. Repeated tripping means something is wrong and should be investigated rather than repeatedly reset.

Common causes

A faulty appliance (kettles, washing machines and outdoor equipment are frequent culprits), moisture in outdoor sockets or lights, a damaged cable, or an overloaded circuit.

Simple checks you can do

Unplug everything on the affected circuit, reset the switch, then plug items back in one at a time. If it trips with nothing plugged in, the fault is likely in the wiring and needs an electrician.
