My outdoor patio lights failed. A circuit breaker in the fuse box in garage beeps. I assume I should replace this breaker. Comments as to my intended action? Thank you.
Hi Bill,
Typically a problem with an electrical circuit does not damage a circuit breaker, it just causes the breaker to trip off. The circuit and the light fixture should be inspected for a faulty condition and repaired as needed. The circuit breaker should then be reset and turned back on to test the circuit for normal operation.
I hope this helps,
Dave
