We are having difficulties figuring out the shorepower. Everything

to 110 but it trips the breaker on the dock as soon as we plug it in.
We tried using the neighbour's pigtail (which works for him) and it
still trips it. We have the Xantrex inverter/charger and have
adjusted the powershare level to 10 (from 30).

Any ideas?

after shutting off all breakers in the 120 v circuit, put a voltmeter
inline with the pigtail to see if, in fact, you are still drawing
current. I'll be you are. You will need to trace / fix that.

You probably have an unswitched appliance
