Connect 120v Gen to 50Amp ATS?
How is a 120v only generator connected to the gen input of an automatic transfer switch in a 50 amp coach? Is the hot lead from the 120v gen simply connected to (and shorted across) both the L1 and L...

The manual I read has two 30 or 35 amp breakers so while it is single phase each pole may get connected to each side.
Yes! I suspect that's exactly what I will find. I was thinking about the 4.0CCK Onan 120 v gen in our first coach when I asked the Q. I had forgotten that I'd read in the HKAK manual that although it was single phase 120v, it had a split output. The CCK would be bridged across L1 L2 in that application (it has only a single output and no breaker).
That means that one could only pull a max of 33 A on each of the 50A branches even though the HKAK gen is rated at 66A. One couldn't pull a full 50 A on either branch if one needed to.
The 2800 watt inverter in the all-electric design would probably be bridged across L1 L2, since it isn't a split output.
Thanks to all for the comments.
