30 amp for duel AC

I can and do run both AC's off a 30 amp service. The lake does not have 50 amp, so 100+ degree days need both to stand a chance of sleeping. I have to turn off the converter (battery charger) and run a minimum of lights, fridge on propane no microwave or electric water heater. Biggest issue is starting one ac, and letting it run a min before starting the other. Once they start cycling, it gets exciting. I do usually trip the 30 amp breaker once or twice a trip.

.........You could probably run two small 5,000 btu window units on 30 amp , minus any microwave or electric water heater usage ! , jf

You can run both off a 30 amp service if they are 13.5 high efficiently AC units as they only use about 9.5 amps and you limit your other use.

It is a Dometic, Model RM 2862 It's in my 05 Cardinal

I think a closer reading of the OP's question is in order. He or she are asking if the two AC's will run on 30A "SERVICES".

Any modern RV with TWO AC's will have a 50A system.

The answer is YES by turning off all major electrical draws and running them on propane if possible.

Yes I have run bOTH AC's on our 07.5 MS on a 30A SERVICE.

Make and model?
I would say the circuit board is suspect.
I am guessing that the 120 volt relay is stuck with contacts closed.

Since we are talking refrigerators, I can't turn mine off, as soon as I plug into SHORE POWER, it comes on. Doesn't matter if the lights on the front are on or off, I can push the on/off button, the lights will go off but not the fridge. Unhooked the shore cable and have a charger on the battery, to keep it charges, gas bottles are off.

Not in the A/C refridgerator business, but I have heard on many occasions that abruptly shutting down the compressor while operating has a deterious effect that may cause it to fail! Tripping the circuit breaker would have that effect wouldn't it?

Downstream equipment is protected. That is WHY the breaker trips.

(If high demand causes a low voltage situation, that is a whole nother worm-can.)

OP-At a campground I meet a man who had 30A service to his rig. He added a second AC in the bedroom and the installers ran a wire in the ceiling and behind the bathroom sink to the bottom outside of the RV. He then runs an extension cord to the campground breaker box. May not work for you but may be an option.
