can Circuit breaker go bad?
can Circuit breaker go bad? i have a 100 watt circuit breaker for the main breaker to my house. for the last seven years since i have moved in, it has never tripped. we finally turned on the AC the beginning of August and over the last few days it has tripped. when i go down i can smell something burning and the breaker is very hot to the touch. i set up a small fan to keep it cool and it's working good, no trips since the fan. why this year all of a sudden? how much can i expect to pay an electriction to come out and replace it?
