I am refinishing my basement and for a while we were experiencing a power outage in that circuit. I checked the breaker and saw that a switch had tripped, so I shut it off and back on again. Now I have power to only a few outlets and the overhead lights, but the majority of the outlets do not work at all. I have replaced a plug on one of the faulty outlets and still no power. Any thoughts?

It's possible that whatever fault caused the breaker to trip also damaged some wiring or one of the fixtures/outlets. I'd run through the whole thing with a circuit tester with the power off and see if I could identify a break.

Did your refinishing involve a DIY wiring job?

No. All we did was take down some paneling and put up drywall. We only have drywall on the ceiling so the walls are still accessible. What's involved in "running therough the whole thing with a circuit tester"?

It's possible that one of the screws or nails you used to fix the drywall pierced a wire. If you cut the circuit breaker, turn off all the switches, and connect an ohmmeter between the hot and neutral, you should get infinite resitance. Then turn the lights on one buy one, and every time you trip a switch, the ohmmeter should show just about zero ohms. When you find one that doesn't make the meter move, there's a fault wither in that switch, that fixture, or in the wiring between that fixture and the previous one. That may tell you where you need to tear out drywall to find the problem.

When you're working in the main panel, beware that you are working in an extremely hazardous area. If you don't have training and proper safety equipment, it's probably best to find someone that does. Remember that the panel is always full of 240V and far more than enough amps to kill you if you make a mistake.

Thanks. Those outlets weren't working prior to the installation of the drywall. I better call someone.
