Hello everyone me with the surprisingly still floating boat with all the problems it’s pretty amazing! 
Anyway this one maybe serious the marina done a test on all the boats on my dock and of course I won. Apparently my boat is putting 2.4 milliamperes of electricity into the water causing a dangerous condition in the water and the docks power to trip. The guy testing was helping me troubleshoot and I had everything off but the main power into the boat and it was the problem. 
Can anyone help me with this or know anything about this? Please help

    I don’t know if this helps but I was at the boat today trying to troubleshoot this and it seems to happen when I flip my dc switch on and without the shore power it is not showing any charge but I turn the shore power on and it has a good charge. Also, when I flipped the dc switch on the lights kinda flickered a little.

    A few years back my friends boat was putting about 2 volts into the water. Troubleshot it down and found that he made an "extension cord" out of romex and ran it from his electric panel (microwave outlet) to the cockpit for a table lamp. Once that romex was removed no more voltage in the water. Now with that said I would check the wiring for non marine grade wire, loose connections, bad grounds. Also make sure A/C ground is not connected to D/C negative.

    Are you sure he said 2.4 mA?  That's not enough to trip the breakers.  They usually trip at 30 mA.  

    [EDIT - REWORDED THIS PART TO BE LESS CONFUSING]
    If you are consistently tripping the dock breakers, try turning off all of the breakers on your boat's AC breaker panel.  Connect shore power, then turn on your boat's AC breakers one at a time.  See which one trips the dock breaker.  

    You might have a PowerPole connector that is failing.  Read this discussion:

    Thank you Raybo I will start behind the fridge when I was looking for the screws to take the helm seat off I had to climb in there and maybe my big butt pulled something loose. Could it be something like that?

    The new GFCI breakers will trip if you even sneeze or give them an awkward look. Check behind your main panel and make sure the ground and neutral are not on a shared bus. 2 is below the threshold but maybe the meter wasn't reading correctly or the dock breaker may need replacing. Have you tried another shore power of the same style in that marina. 

    My 280 was on a shared bus which was causing this problem at a newly renovated marina with GFCI breakers.
