Safety switch keeps tripping
A safety switch trips when it detects current leaking where it should not. Unplug everything on that circuit, reset it, and plug items back in one at a time. If it trips with nothing plugged in, call us.
What to do right now
- Unplug or switch off everything on the affected circuit.
- Reset the safety switch once. Do not keep resetting it if it trips again straight away.
- Plug items back in one at a time. The one that trips it is the culprit.
- Keep that item unplugged and do not use it until it is checked.
It is an emergency if
You smell burning, see scorch marks or sparks, or feel a tingle from a switch, tap or appliance. Leave the circuit switched off and call.
For fire, smoke, shock injuries or fallen lines, call 000 first.
Common causes
A faulty appliance
Kettles, heaters, washing machines and power tools with worn insulation are the most common cause.
Moisture in a fitting
Outdoor lights, garage power points and bathroom fans let water in, especially near the coast.
Damaged or ageing wiring
Cable damaged by rodents, nails or heat leaks current into the wall. This is the one that needs an electrician.
What we do about it
We test each circuit with an insulation tester to find where the leak is, then repair or replace that part. We do not just swap the safety switch and hope.
Common questions
Is it safe to keep resetting the safety switch?
No. It is tripping because something is wrong. Reset it once to find out what circuit is affected, then stop and get it checked.
Can I just bypass it?
Never. The safety switch is what stops a fault from becoming a fatal shock.
