Running AC while working on renovation

Hello all! I purchased two coleman AC rooftop units this past weekend and would like to install them in my bus so I can remain cool while I continue to work on it. My question is...can I safely wire them up to plug directly into a generator? I have an 8500 watt generator that I use in case of Hurricanes (it got a lot of use after Irma) that should be able to run both. They are 13,500 BTU. Thanks!

Hey Moq,

You can wire them up to run off of the generator. An 8500 watt generator should run both of them without trouble.

I have run a pair of roof a/c's from generators as small as 6000watts.

Anything designed to run from 110-120V peaks at 1800W. Higher powered items require 220-240V.

So even the biggest Coleman units paired together would run from a 4000W generator, with room to spare.

Also a 12 gauge cord is essential for each unit and would not go much more than 50 feet

Harbor freight has 25' 12gauge extension cords for $20. You could pick up a pair of those, cut the female ends off and wire them to your a/c's. Easy peazy.
