Would not hurt to measure AC draw.
My 15k Carrier draw 8.2 amp while running, so theoretically I could run 3 of them on 30 amp service, but the motors have huge spike while restarting and that is why they require bigger power line.
Common sense if you want to use 3 of them is to set thermostats on 2 to low and let the 3rd one cycle when it gets too cold.
That will avoid the potential situation when 2 might want to restart in the same time.
I do not know where you are getting your figures, but ALL RV Carrier units draw a minimum of 12.7 amps(Compressor and HI fan) at 95 degrees ambient. DROP 1 amp for each 10 degrees below 95. That means if you are pulling 8.2 amps, then the outside temp would be about 55 to 60 degrees????? IF that 8.2 is the compressor only, then you need to add the 2.5 to 3.0 amps for the fan motor. Which means you are pulling 10.7 amps at 75 degrees. Then why run the AC???? The ONLY exception to this is a Carrier 220 volt RV AC unit, which I have never seen and I doubt any OEM would have installed one. Doug
