A few weeks ago I had a breaker that would trip a few minutes after being reset. This was in a house I was working on. I took amp readings on the circuit and it was no where near 15 amps (around 1-2 amps maybe).
I found the problem to be two outdoor lamp post on a light switch to be the culprit. I changed the breaker to eliminate a weak/bad breaker. Inside the lamp post I found a wirenut had fallen off but, didn't make sense that the breaker did not trip immediately upon reset, indicating a dead short so I checked all connections to make sure they were tight. After replacing the wire nut and checking all connections and verifying the photo-eye wiring, everything seemed to work fine and lasted for 2-1/2 weeks. Today I got a call that the problem has occurred again. However, after all I did to correct the problem, I'm not sure what to check next.
Any ideas where to begin/continue troubleshooting?
