Why Does My Circuit Breaker Keep Tripping?

A breaker trips to stop a wire from overheating. There are three causes, and they call for different fixes.

Cause one: overload

Too many devices on one circuit. A space heater, microwave and toaster on the same kitchen circuit is a classic case. Signs: it trips only when several things run at once, and it resets normally. Fix: move devices to another circuit. If there is no other circuit, an electrician can add one.

Cause two: short circuit

A hot wire touches a neutral or another hot wire. Signs: it trips instantly, sometimes with a pop, a burning smell or scorch marks. Do not keep resetting it. Turn the circuit off and call an electrician.

Cause three: ground fault

Current leaks to ground, often from moisture or a damaged appliance. Signs: a GFCI outlet or breaker trips, especially in bathrooms, kitchens, garages and outdoors. Unplug the appliances on that circuit to see whether one is the cause.

What you can safely check

Unplug everything on the circuit, reset the breaker once, and add devices back one at a time. If it trips with nothing plugged in, or the breaker will not stay reset, stop.

Call an electrician if

The breaker is hot, buzzing, scorched, trips immediately, or the same breaker trips repeatedly. A breaker that fails to trip when it should is dangerous.
