Main information
What it could mean
A circuit breaker trips when a circuit's load exceeds what it's designed to handle, either from a temporary overload or a short circuit.
Safety first
Don't reset it several times in a row. Reduce the appliances connected to that circuit before trying again.
Next step
If it trips instantly with nothing connected, a short circuit in the circuit itself is likely, and it's worth checking before restoring power.
Frequently asked questions
Why does the breaker trip when several appliances are on at once?
Because combined demand exceeds what that specific circuit can handle.
What does it mean if it trips with nothing plugged in?
Usually points to a short circuit in the wiring itself, not the appliances.
Can I tell which circuit is affected?
Yes, by checking the switchboard label if it's marked, or by testing which one matches the powerless area.
