I think I have at least isolated my GFCI tripping problem. I discovered that I
had continuity between the neutral and ground at the bus shorepower receptacle.
I pulled the AC power panel cover and confirmed continuity there as well. I was
lucky to have a couple of extra holes in the buss bars so I clamped my voltmeter
leads in. Pulled white wires off the buss bar until I got an open circuit.
Replaced the others and the circuit remains open. Button it up, and I've got
good shorepower without tripping. Took about 5 minutes all told. Now I just
need to hunt down the white/ground short on the affected circuit. That might be
more time consuming.
