What was confusing me is that with the switch turned to rear BOTH a/c units work WHEN ON GENERATOR. Then I did the math. My 5000 watt generator is capable of near 42 amps. ( 5000 watts ÷120 volts. ) It has 2, 120 volt outputs one 30 amp output goes to the main input and second 20 amp output, to the second air conditioner.
On 30 amp shore power 2 a/c exceeds that draw.
16ACE27 good idea on the second line to the 20 amp shore power
Bob Denman the old Colemans draw 23 amps to start 10.4amps running. The math explains it. I could "technically" get them working but the minute one fires up and the other is running it would draw 33.4 amps and POP GOES THE BREAKER!
Thanks everyone for the help. I guess I will deal with this for another year or so then upgrade!
