My needs are few ... microwave(1000 watts), toaster, coffee maker and heater(1500 watts).
The OP was using 2-line electric
to 2 outlets and to a plugged in charger
to charge an isolated battery
to run a Frigoboat fridge. I was told this wiring
would suffice since it's an isolated system.
for 30 amp(from the electrical
box), evidently requires 10 guage or larger wire ... it has 14 guage. No fuse, no breaker no where on the AC side .... just the hot and the common ... not good.
I'm going to put in a 30 to 15 amp breaker box(3 separate 15(or 10?), amp lines, plus ground fault protection. I'm changing the wiring to 10 guage for the hot, common wires plus the green ground.
Since the Ac system is isolated from the DC, I wonder if I should ground the green wire to my engine(my DC ground), or if the green wire returning back to the shorepower box will suffice, since the AC power is separated from the boat's DC wiring.
Are galvanic issues a realistic reason to keeping the AC ground from the DC ground?
