Air Conditioner?

Since folks were so great about answering my last question, I am going to get really brave and show you guys how little I know. I am on my 7th camper and have never had air conditioning until
now. My question - is 50 amp required to run the air conditioner or can it also be run on 30 amp? Yes I am embarrassed to ask this question.
  • If you only have one AC you can even buy a adaptor and run it on a 20 amp circuit like the ones in your house. You can not run anything else on that circuit then though.
  • If your RV is 30A rig....then you can run the A/C on 30A

    If your RV is 50A rig....with an adapter (50A to 30A) you can run your A/C on 30A...might have to do a little AC load management (water heater on propane, fridge on propane....microwave may/may not at same time A/C on)

    No need to be embarrassed. 50 Amp systems are usually for 2 30000 BTU air conditioners. 30 Amps will run 1 30000 in a travel trailer and most TTs are equipped with only 1. You can also buy adapters for 50 amp to 30 Amp cords, 30 amp to 50 amp cords. Look up wiring a 50 Amp cord and 30 amp cord and I'd recommend you buy one so in case you run into a 50 AMP space as the only one left you can take it.

    Most RV air conditioners are 13,500 BTU/h, although there are a few with 15,000 BTU/h units. But your 50/30 amp info is good...
