The power in my house just went out for maybe 15-30 seconds. When the power came back on, one of my AFCI breakers was tripped. Thing is, I can't get it to stay back on. Every time I turn it back on, it trips after about 45 seconds. I went upstairs and unplugged everything from the outlets in the bedroom and turned off the switches, but it keeps on happening. I tested the circuit with the test button and it worked, but the breaker keeps tripping. Any idea what could be going on?
EDIT Added picture of breaker
Well it's what I expected - the breaker was bad. Hooked up the circuit that was on it to another AFCI in the panel and it worked fine. Hooked up a good circuit to the bad breaker and it still tripped. POS AFCI breakers...
