Re: Getting ready to add shore power
Yes, put the frig on the breaker with the outlets. Just be sure your total draw with the frig and the outlets doesn't exceed the breaker size.
In the pic you posted above, you can't see the back of the panel. I assume it has TWO breakers for the main line. You need a breaker on BOTH the hot (black) and the neutral (white) incoming AC wires.
It this panel doesn't have two breakers for the main shutoff, then can it and find one which does.
