GFI circuit breaker not resetting
I have a 30 yr. old house with the usual electrical system of circuit breakers. There is one breaker which is a GFIC type complete with a test button. This circuit runs into the outlet in the bathroom and an outdoor outlet. We had a Christmas light set up using the outside outlet when a lot of rain soaked the lights out front. I turned the lights on and they went on for less than a minute then all went out. I checked the circuit breaker and it had tripped. I reset it but nothing happened. I double checked the outlet in the bathroom and it doesn't work either. The test button on the breaker doesn't reset despite switching the breaker back and forth. Any advice out there?
