Yup, I did miss those earlier posts, Johnny. Sounds like you have the situation well in hand.

Jerry -
You missed a couple of posts. This coach never had an Onan in it. Norris had as far as I can tell the local electrician wire the coaches. All done
in 12-2 with ground stapled down. I've no idea how it's attached where I can't see it. They used a cheap Bryan 110 panel, into which they put one 40
and two 20 amp breakers. They fed the forty from either the shore cable or genset, with a 30 amp double throw wall switch (which failed) which I
replaced with a relay. Bless them, the feeds are home runs from the water heater, A/C, and outlets on each side of the coach. They fed the A/c and
water heater off a double throw switch so you can have either one. The other runs were combined in a utility box beside the panel. Since the genset
I'm installing is greater capacity than the original - double in fact - and 240 volt, I've put the A/C on one leg in the panel and the water heater on
the other. The four home runs will be divided between sides. This keeps the microwave and icebox on separate legs. I'll put the second A/C on the
water heater leg, and the new 12 volt supply on the other. This will balance the load fairly well. Whether the panel is fed by shore 50 amp or the
genset doesn't matter - both provide a pair of 120V legs. They're out of phase on the genset since it's a 110-220 set. Whether they are on shore
50Amp pedestals doesn't matter, nothing in the coach sees both legs anyway. I picked up a dual 30 amp breaker to feed the panel, but I'm gonna take it
back and pick up some more individual 20s. The genset has breakers on each leg, and shore pedestals do as well. I see no difference in how this is
wired relative to my house, as far as the 110 goes. Neutral and ground are separate throughout, so a GFI feed won't be bothered if I encounter one.

This generator is a tiddler, 7KW. The ones we used at work, aside from the Onans on remote trucks ran from 30KW to 300KW from Onan or Kohler, and at
one shared site we had a megawatt Cat plant. I had wanted an EMD for bragging rights, but the money wasn't right. A bud who worked offshore rigs
told me later that the EMD plants didn't do real well in standby service, but were rocks when the were run fulltime.
Anyway, this setup ought to work. 7 heathen chinee KW from the generator or shore, and 60 amps of 12 volts ought to be asufficient.

Sooo, I now have a spiffy GE 8 breaker panel installed with all the feeds on separate 20 amp breakers. And I now have a PD 9160 60 amp DC supply installed in place of the 40 amp brute force box. Since I have a solar charger for the house battery, I left the battery switch installed. I tuen it off when the coach is at home and powered, back on when we head out. NOW I can get back to installing the heathen chinee genset, there's something to connect it to. Yet to go besides that are/is/am the firefight system, the icebox fans, and some new parts on the TV antenna. I think I'm gaining on it.

Does anyone know, is the fan supposed to run continuously on the Progressive Dynamics power supplies, or is it temp controlled? Mine is room temp, the fan is still. If it's supposed to be running, I'll replace it.

Johnny, The fan is temperature controlled. Runs on load. At least, this is true on mine.
