A tripping switch is annoying, but it’s also a sign that your consumer unit is doing its job, cutting the power because it’s detected a problem. The trick is finding out what that problem is.
Common causes
- A faulty appliance. Kettles, toasters, washing machines and immersion heaters are frequent culprits.
- Overloaded circuit. Too many high-powered appliances on one circuit at once.
- Moisture. Water getting into outdoor sockets, lights or junction boxes, especially after heavy rain.
- Damaged wiring. A nail or screw through a cable, or old wiring breaking down.
A safe way to find the culprit
- Switch off and unplug everything on the affected circuit.
- Reset the tripped switch.
- If it stays on, plug appliances back in one at a time, waiting a moment between each.
- When it trips again, the last item you plugged in is likely to be the fault. Stop using it.
If the switch trips with everything unplugged, the fault is likely in the fixed wiring or a fitting, and you’ll need an electrician to trace it.
When to call straight away
If you notice a burning smell, scorch marks, buzzing from the fuse box or a hot socket, switch off at the main switch if it’s safe and call an electrician. Don’t keep resetting a breaker that won’t stay on.
