Several causes are possible
An overload, faulty appliance, moisture or installation fault can produce a similar symptom. Only an appropriate diagnosis can identify the cause.
- Tripping linked to one particular appliance
- Tripping when several items operate together
- A persistent fault when usual appliances are switched off
What to record
Note when the breaker trips, which area loses power and what appliances were running. Never force a protective device to remain on and do not open the panel.
When to move away
Unusual heat, a burning smell, crackling, smoke or black marks mean that the installation should not be touched and the situation should be treated as potentially dangerous.
