Onan Emerald Plus 5000
Wondering what exactly the bottom switch ( circuit bus 2 H.A.C.R.) in this picture controls? I've had a 2000 Suncruiser for 3 years and this is the way it's been since I bought it. What's it do? ...

If you have 50 amp service, the bottom breaker supplies one of the two hot legs with 120 VAC when on generator power. If you have 30 amp service with two rooftop A/C's, the bottom breaker supplies one of them so both A/C's can be operated at the same time on generator power. There's usually a selector switch that has to be in the correct position to enable both A/C use in that case.
My motor home does not have 50 amp service, it’s a 30 amp coach. Nor do I have two roof to airs, we have a basement air conditioning unit that has two compressors. I’ve always wondered if the second compressor runs when the generator is on. It seems like when we were plugged into 30 amp shore power my load meter reads a lot higher with the air on than it does when I run the generator. If I flip the switch will there be any issues?
