Jim & Barbroof ac units
Does anyone know if you can run both roof top ac units off the generator?
A friend said I should try it and said it should work without any problems.
I put caution first before I try it.
The guy I bought the Barth from said he never tried it and was told only to run one at a time when he bought it.
Any ideas?

bill hI would presume that, since you have two air conditioners, you have a 5.5 to 6.5 kw genset and 50 amp service. If so, a healthy genset will run both ACs. I run both off my 6.5 now. Before I started using Red Line fuel system cleaner, it was not always a sure thing.

davebowersI agree with Jay, this is assuming that you have at least a 5.KW gen which I am almost sure you do have and if you are plugged in that you have 50 amp service. I am virtually certain that you have 50 amp in the coach but you will probably have problems if you plug into a 20/30 amp campground.

davebowersBill, look at the dates and times of our last posts. Are we on the same wave length or what??

A 30 amp campground receptacle will run one air conditioner OK, but beware of low voltage on 20 amp outlets. I would never run an air conditioner on ANY outlet without an accurate voltmeter.
When I was a perm at a park, many folks had their unit burn up a motor(either compressor or fan) from low voltage, especially on hot weekends. I used a variac.

Jim & BarbThanks Guys,
I have a 1985 Regency 8.2 Detroit and I think the generator is 5.5(I'll have to check that to make sure).
I have 50amp service and do know that if I use an adapter plug to 30amp service I can only use one ac.
All this time when we ran the gen. I would only use the front ac- now I feel a whole lot better since the warm weather down here is starting to roll in.
Thanks aagin, Jim

ironsidesJim, Mine is a 6.5 4 cyl. propane fired and will certainly run both airs at once. problem is none of these coaches were built exactly alike in equipment so it's always good to check first. i don't think you should have any problem though.

dogillMy 7K Kohler handles both A/C's fine but I watch how many other appliances I'm running at the same time. I switch the ref over to the LP only setting and don't use the oven with both Airs running. And especially watch out if you have a hair dryer. Those liitle jewels must pull more amps than anything else on the rig.
Trivia question: What kind of fuel economy (GPH) does your genset get, running one (1) Roof air while travling? Mind seems pretty lousy but may be par with the Kohler 7K.

Jim & BarbBoy was I wrong about my generator it's not a 5.5 it's a 7.5. I shouldnt have any problems at all.
Dogill- mine is also a kohler. I think it was under a gallon an hour but not certain.
I thought it did fairly well at top off time. It uses reg.gas and has a 40 gallon tank. Thats running the ice maker, frig., lights and one ac. I'm trying to think of a nice way to change from blubs around the bathroom mirror to fluorescents. Theres enough bulbs in there to give you a sunburn.
Thanks to all- Jim

Jim & BarbJust got back from a trip to S.Carolina.
Ran both ac's and what a difference that made. Barth was real cool inside and the gen. ran fine. I did take dogill advice and left the frig. on LP. Did notice that it used over a gph running both ac's and the ice maker.
