Why Does My Circuit Breaker Keep Tripping?

A breaker that trips once may be responding to a temporary overload. A breaker that trips repeatedly is telling you something needs attention, and repeated resetting isn't the solution.

What was running when it tripped?

Think about what was operating right beforehand. Did you just turn on a heater, hair dryer, microwave, vacuum, power tool, or another high-demand device? Too many loads on one circuit can cause an overload.

Unplug obvious loads

If several portable devices were running, unplug some of them, then reset the breaker once using the normal panel control. If it stays on under reduced load, overload may have been the cause.

What if it trips again?

Stop resetting it. The problem may involve an appliance, a device, wiring, a short circuit, a ground fault, or another electrical condition, and all of those need diagnosis.

What if the breaker feels hot?

Unusual heat, a burning odor, discoloration, or buzzing around the electrical panel is a stronger warning sign. Don't remove the panel cover.

When should I call an electrician?

Get professional help when:

• The breaker repeatedly trips.
• It trips with little or no obvious load.
• You smell burning.
• The panel or a device is unusually hot.
• Lights or outlets misbehave at the same time.
• You suspect damaged wiring.
