AC voltage and line loss
Hey guys, I have a 96 Bounder 34j with two brand new Coleman 13,500BTU AC units.. the weather is extremely hot right now and everyone is running their AC’s... even with my Hughes Autoformer I’m runnin...

A 50/30 adapter may give you better voltage but the rig panel will still limit the amps to 30A for the rig.
Normally CBs are sized based on wire size and usage and the recommendation is to limit the continuous load to 80% of the CB. This helps to keep the CB and plugs from getting to hot. RVs are no different than houses in this regard.
Finally for a 30A or 3600W rig you'll often find a gen of 5000W or so. And the back A/C is automatically connected to a 20A CB on the gen resulting in being able to run both A/Cs on the gen but not shore power. So helpful while on the gen but not so much when on shore power. :(
Keep in mind that if the back A/C is 13K or even less it doesn't draw 20A so all of the remaining available amps are available to the rest of the house.
