Breaker keeps tripping after a power outage: what to check

When power comes back after an outage, everything that was running tries to start at once. AC compressors, refrigerators, freezers, pool pumps, and well pumps all pull a surge when they start. On a hot Bakersfield afternoon, that combined surge can be enough to trip a breaker that would never trip in normal use.

Outages can also bring voltage swings or surges when power is restored. That can damage electronics, motor parts, or a device on the circuit, and a damaged device can cause repeated trips. A breaker or connection that was already weak can also give out under that stress.

First, turn off or unplug large loads: set the thermostat to off, and turn off pumps and big appliances if you can. Then reset the tripped breaker once by pushing it fully to off, then back to on.

Bring loads back one at a time, a few minutes apart, starting with the fridge. If the breaker trips when one particular appliance starts, that appliance or its circuit is the likely cause.

Check GFCI outlets in kitchens, baths, garages, and outside. They can trip during outages and leave outlets dead even when no breaker is tripped. Our guide on partial power covers this.

Stop resetting if the breaker trips right away with everything off, if it feels hot, if you hear buzzing, see scorch marks, or smell burning. Also call if half the house has power and the other half does not, which can point to a problem with the service or main connections.

Electrical ASAP answers 24/7 at (661) 293-0213, and we treat burning smells and hot panels as urgent.

If your whole neighborhood is out, or power is flickering on the street, that is PG&E’s side, and you can check PG&E’s outage information. If neighbors have full power and you have a tripped breaker, partial power, or dim lights, the problem is more likely on your side of the meter.

On an after-outage call, we look at the tripped breaker and the panel for heat or damage, test the circuit for shorts and ground faults, and check the appliance or equipment that trips it. We also check the main connections, since outages and restorations can expose a weak connection.

Then we explain what we found in plain words and give you options before any repair. Troubleshooting visits carry a service fee that covers the first hour of labor, including diagnosis, and we confirm what is included before we schedule.

A whole home surge protector can help protect electronics and appliances from surges, including some that happen when power is restored. If outages are a regular problem for you, a properly installed backup generator with a transfer switch is another option. A licensed electrician should install either one.
