My main circuit breaker on the AC panel has 2 lights - labeled "Circuit Breaker" and "Polarity". The Polarity light is wired between the neutral and ground wires and would light if there was a reverse polarity condition. The "Circuit Breaker" light is wired between the hot and neutral terminals of the breaker so it should light when the main breaker is turned on. When connected to shore power with the breaker on, it doesn't light. I connected a Honda generator to my shore power input (using a Marinco adapter)and the indicator light works. Tests with a volt meter do not show any problems. Does anyone have a similar panel and, if so, does the light work when plugged into shore power?
