AC voltage and line loss

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?

Thanks guys! Good to know about the amp thing, but if that’s the case how do they expect you to run both AC’s? With the Intelligec system running two AC’s at the same time is supposed to be it’s feature. Other than that the converter, fridge, and a bunch of smaller electronics are running. When AC is off completely all my toys run at 4 amps.

I have the Autoformer plugged into the shore power, the surge guard into the Autoformer and the RV into the surge guard... the surge guard was showing 29amp when both AC’s were on earlier. I have the little digital voltmeter from Hughes that came with the Autoformer plugged into an outlet over my couch.. the AC units seem to drop the internal voltmeter by about 3 or 4 volts per AC. I would consider upgrading to a 50 amp service if my Intellitec would still work for my heating and cooling but I don’t know if that’s the case... With the heat we are having here I need to run both AC’s here for a few days.. these units are now about two months old and the main unit has ran about 12 hours today for the first time ever.
