Ummm, I'm into INsignificant voltage drop. No way in hell am I going to force 10AWG to swallow 40 amperes. I wired Quicksilver with 10/3 marine wire to feed a max of three 20-amp receptacles each breaker. Even the 127vac plug is a cheater, because Mexican receptacles are looser than 10 seamen in Po City. Install a good receptacle in a campground, the minute you leave it is exchanged for a garbage receptacle from the owner's house.
I scan all my breakers and all my switches. The shore power plug and receptacle. If I detect heat, then something is wrong.
