Guys, what would cause a City Power breaker to trip randomly?
It goes for several hours and trips around twice a day at different times.
Single phase 80A breaker.
Amps pulled way way under spec - 34A.
House DB not tripping.
Customer is postpaid.
Have disconnected the feed cable from CP and the DB and Meggered it - all good. No cable fault. CP was in attendance but didn't have an insulation tester.
Any ideas?
