The AC unit's don't tell you start up draw?

Inrush current magnitude has nothing to do with attached load. Duration of inrush current is affected by load.

From doing some reading, a typical 15k btu RV ac unit will take 3300 watts on startup, which is 30 amps on 110ac. Better get a badass generator...lol

Ya no doubt. I was already considering a 3k or 2 parallel 2k's with some kind of box up on the nose of the trailer.


But isn't 3300w / 120v = 27.5a?

Yes, I just did my calc from 110...lol. But generators are usually rated in Watts. 120v, especially from a generator, usually isn't a full 120v.


But if startup is 3300, a 4k gen would be fine.

so sorry, you are correct. duration of inrush current can also have a bearing on whether or not the generator will run the desired equipment. i.e.: breaker could trip or it could just kill the generator altogether. much like it did in the OP's case.
