Electrical Issue/Tripping main breakers then won’t reset. We are having an ongoing issue with our shore power. When we trip the main breaker we can’t get the main breakers- A or B bus to reset. When it trips it trips all the way up to the pier power meter. Both AC breakers remain on the boat don’t trip when we attempt to reestablish power. We are using smart plugs and have replaced one of the smart plugs which appeared to restore power to the panel but when we tripped the main breaker today we are again unable to restore power. It again trips at the pier but not on the boat.Help, it’s cold. Everything runs when we switch on the generator

One brand new smart plug on A bus as that’s the breaker that keeps flipping. Yes we have turned off all breakers and have tried to turn them on with the meter breaker first, pier breaker, main boat breakers and then main panel breakers. When we go to turn A bus on it buzzes for a second, the reverse polarity light and A bs light flicker and the breaker flips off.
Is thistwo thirty’s? On the back of the plug the copper looking screw should connect to the black wire(hot), the silver screw should connect tothe white wire(neutral), and green screw to green wire. This is of couse providing the boat is wired correctly by color. It seems like you have a dead short when you mention it buzzes
Yes it is 2 thirty’s. Hot, neutral and ground are all wired correctly. We’re wondering if the main A breaker on the panel needs replacing? What is a dead short.
As in measuring resistance across breakers or across the wiring? We did read if you flip a breaker too many times it may need replacing.
