I had a 15 amp 480 volt GE breaker trip and won't reset in an MCC while the pump was turned off. The only thing that it was powering was the transformer for 120 volt control power. It also blew the secondary fuse on the transformer, 8/10 amp fuse. I found a loose connection in a JB and hopefully fixed that.
Assuming that the loose connection caused the problem, why would it trip the 15 amp main and damage it? The boss wants to know what happened and I can't explain.
I was in that JB the day before with another problem, a receptacle was tied in to a photo cell and would turn off when the sun came up. So the fingers are being pointed at me. Close to the end of the fiscal year and the budget didn't have $650 for a replacement.
I can't find any recalls or problems associated with this breaker. According to the operators this breaker has never tripped before.
