Aaron,

I'm with Rick; your solution needn't be too complicated; the Coachmen
should have had separated Neutral and Ground busses.

That's correct - my busses are separate at all boxes on my coach - the ground and neutral are only connected at the generator and that neutral is not switched anywhere, nor is the ground from the generator. The comment about the neutral and ground busses being connected was not mine, and it's not actually the problem that I have. I guess the *simplest* thing for me to do would be to put in a double pole breaker at the main generator box - but that still leaves a convoluted set-up with more boxes, more wire, and certainly more junction boxes and wire nuts, than I actually need. Also, if I get rid of the excess boxes and wire I will gain some usable storage space. Also doesn't resolve power for my 2nd AC on shore power. So toss that idea.

As for the switching, I'm not sure ordinary 50A Automatic Transfer Switches
will recognize the 30A plugs you intend to use. Further, there complexity
and cost are not justified. Here's DIY version of a 30A transfer I've
used, without attention, for the past 19 years:

It's simply wired; in fact, mine's in excess space inside my replaced
circuit breaker panel (that's probably not Kosher, 'tho').

Mmmmm, this seems a bit complicated to me. It's certainly a little more than I'm easily comfortable with in terms of electrical diagrams - but it looks like I would need two of the power relays ($50 each), two diodes(14 cents each), and two capacitors (don't know the price.) That puts me at around before the capacitors $100, about $50 less than the switch I am looking at. Basically you built your own automatic transfer switch correct? It might be worth $50 of my money right now to pay some one else to build it for me. I would probably enjoy doing that if I had a little more time for it.

I'll double check on whether the PD52 transfer switch will work with 30 amps - I believe it will, but the connection instructions for that switch are not entirely clear.

[/quote]Your proposed 2nd A/C solution is certainly workable, but in the past when
working on 30A service coaches, I've just added a separate 15A CB box and
line cord for the 2nd A/C. [/quote]

I though it would be easier to rely on the shore power breaker for the rear AC - but it's probably not as good as having my own. I might add in a breaker there for piece of mind.

Thanks for the reply and info!
