I'm considering replacing the original 50 amp plug on the
coach with a 30 amp one. I've yet to see a 50 amp plug-in
at a campground, but frequently see the smaller ones.
We always end up with the unwieldy adapter plugs on the
end of the huge 50 amp oem plug, and effectively end up
with a single 15 or 20 amp 110 circuit.

The original wiring is four wires -- two hots, a neutral,
and a ground. The hot wires each power one-half of the main
breaker panel. In effect, two separate ~20 amp 110 circuits,
assuming you're plugged into a 50 amp outlet.

The 30 amp "camper" plugs I found are basically an oversize
110 plug with a single hot, neutral, and ground.

I can figure out the wiring from the plug to the main
box, but I haven't seen what to do with the Onan output.
Just ignore one hot wire? Rewire the Onan somehow??


thanks,
Karen
