A 30 amp service should only be used at 24 continuous.
If the autoformer is raising the voltage 10%, then on the input side of the autoformer the current would be much higher than 29 amps.
Anything above 107 volts is safe for the air conditioners. How are you checking the voltage inside the RV?
Don, I have seen this 24 amp limit for 30 amp breakers mentioned before. Where does it come from? It looks like Fleetwood didn't adhere to that limit with 2 A/Cs on 30 amps.
While looking at trip curves, I find a circuit breaker, as designed, will maintain approximately 1.13 x its rating for over 60 minutes with out tripping.
