[Rhodes22-list] electrical wiring diagram

[Rick]

Mike,

The 120 v ground I'm talking about is not from an inverter.  Rather, it
comes out of the shore power connection box.  It was twisted with the fuse
panel ground on the original installation.  Am I going to have 4th of July
in April next year?

Thanks,

Rick
