Does anyone have an idea what's happening here. When I plug into shore power the breaker on shore trips immediately this is with the main A/C breaker on the boat in the off position. After checking all wires back to the panel for faults I found that when I disconnect the Promariner Prosafe A/C Ground Galvanic Isolator's main AC supply from the hot side of the main breaker the breakers on shore and onboard do not trip and everything functions as they should. But the Galvanic Isolator monitor is off.
It was my impression that if there was a fault you would get power to the panel but the GI would issue a warning. But the dock side breaker trips immediately with the boat's main AC breaker off. I checked the shore supply and it doesn't appear to be reversed polarity there are many boats plugged in and they tell me their ok. I'm visiting a marina sporting new dock electrical supply stations. What gives and am I still protected form stray current.
