Hello to all. I'm not an electrician or anything like that. I'm just a person with a circuit breaker problem. Anyway, just this morning a circuit breaker went off on us due to heavy usage of electricity. I assumed that I could just simply switch the circuit breaker back to on in the circuit breaker box and everything will be fine but so far no luck. The electricity simply won't come back on so I'm not sure if the circuit breaker needs replacement or what. Here's the information on that particular circuit breaker:

Arc Fault
Breaker
Type BRAF

There seems to be a TEST button on this circuit breaker as well. Any ideas?
