4000 watt generator for 30 amp 120v RV?

4000w will be over the capacity that your rv can handle, so you should step it down just a notch. The reason your ac kept setting off the breaker is because you didnt have enough amps for it to run on. What you need to look for is a 120v 30amp generator in the 3000-3600w range. Anything higher can and will fry some of the electronics inside the rv. My family owns a small deer camp and we have electrical outlets to run our campers on. when we initially put in the power the electrician accidently put us on the 220v line and we had to replace everything that was plugged in.

EDIT:

You can also contact a local rv dealership to see what they recommend and they might just have the perfect generator for you.

30 Amp Rv Generator

Once the compressor has built up some pressure, it'll have a tougher time restarting against that pressure, so your startup amps, which can be as high as 250% of running amps, require more than the generator can provide. Startup amps should only peak for a second or so, but if the compressor has troulble coming up to speed with the available voltage/current, it'll overamp and trip the breaker. Like one of the other responders said, the ratings on those generators are exaggerated a bit anyway.

30 Amp Generator

As stated above just call ur local RV dealer and they can tell u "exactly" what size u will need instead of guessing, this way u save urself a whole lot of time and $ due to the fact u may fry something.. U also may want to ask the same question in a different category on here cuz this is car audio maybe maintenance/electronics and manualy choose the category u want instead of auto cuz the comp prbly pikd this sub-category for u.
