Three A/C's and ...

[Greyhound]

I have on my coach, three roof airs with heat pumps and inside a residental refrigerator. The DW wants to run all three A/C's at the same time and I opt not to due to power draw.
At the pedistal, I have a surge protector, followed by a Hughes Autoformer. Inside is a meter for monitoring.
My concern is with all three going and the refrigerator doing it's thing, is I am at the edge of my draw and should something else be turned on I will start popping breakers. Currently I have the water heater on gas.
Thoughts/comments are appreciated.

If you have 50 amp at the site you should be good to go, if you have 30 you will definitely throw breakers, Your Rig, as long as your incoming shore power is adequate should be able to handle everything on, G

I agree that a 50A hookup will be OK, but definitely not a 30A hookup.

Remember that 50A service is really 100A service. It's two 50A circuits, where 30A service is indeed just 30A.
