I knew when this topic was posted that it was trouble! There's real world and there is textbook....I happen to be a little of both. I know for a fact that I have run BOTH of my 15,000 BTU air's on 30 amp power and I happen to be blessed with a voltage/amp meter's on one display when connected to 30 amp and two display's when on 50 amp in the motor home. In 30 amp situations, I may or may not use my auto-former but always use my Surge Guard(over/under voltage protection too).
There are a ton of scenario's that say it can't be done yet it is done. I don't sit on top of my voltage meter's watching it as the compressor's go on and off generally because if I'm using both AC's , it's HOT and the compressor's are mostly on. My Refer is residential and it stays on, my batteries are generally already charged so the inverter/charger stays on. I will admit that I did just replace my front air(after 15 year's)...oh it's still work's but decided I wanted the Atwood ducted model instead of my Carrier non ducted.
Soooo, have at it and tell me how it can't be done and that I'm ruining my electronic's!
OH...there has also been plenty of times I couldn't do it also...more times than I could actually but if Hot, I'm always willing to try while keeping a close eye on things. :-)
