About two to three weeks ago, my circuit breaker that controls my outdoor outlets and lighting began to trip. Also on this breaker is my ring doorbell which is how I discovered I had an issue with that specific breaker. Only outlet being used at the moment is for my sump pump which is plugged into a GFCI outlet.
Three days ago, while troubleshooting, I discovered I had a set of Bluetooth speakers plugged into another GFCI outlet via an extension cord. After inspection of the extension cord, I discovered it was damaged/cracked. I removed it from the outlet and tossed it. Breaker was fine for nearly two days. I thought problem was solved.
Unfortunately, last night it tripped again. The only items plugged in on that circuit are a sump pump and my Ring doorbell. It's been pouring in NYC since midnight and sump pump has been working fine. It's been nearly 17 hours since resetting my breaker without a trip.
I'm sure it's a matter of time before a trip. Any other suggestions to troubleshoot before calling a pro?
