Wouldn't that make more sense that having two 30 amp cords? If you had a 30 amp only site, you would be limited to one AC unit. You could also use the "cheater" that allows you to hook to a 30 and a 20 amp outlet and power both legs. Couple that with a good EMS and I would think it would be a nice setup.


Most of the Eagle Super Lites come from the factory with only 30 AMP service; the 31.5 FBHS only comes from the factory with 30 AMP service and a second A/C cannot be added at the factory for this reason. 30 AMPS would not be enough service to run both at the same time, so I had to have the RV dealer install the second and run it on its own powercord and breaker. The adapter you are showing is a 30 AMP and 15 AMP that allows you to plug a 50 AMP cord into the adapter and get 45 AMPS. both my cords are 30 AMP plugs so this adapter would not work; however I have seen a 50AMP adapter that has to 30 AMP pigtails that could work (not sure). I am not an electrician so not sure the best way to plug the rv in. My thoughts would be again to run the RV 30 AMP powercord to the 50 AMP plug using an adapter and surge protector ad thei run the second A/C powercord to the 30 amp plug. Just wasn't sure if this would harm electronics over time.

What happens when you go to a campground that only has 30amp service though?

Also, I thought that most campgrounds had either 50 or 30, but not both at the same site. Are there a bunch out there that have both available?

Right - I was suggesting that it might be better to convert the camper over to a 50 amp plug and it might make your life much easier in the long run - but I realize that is quite a bit more work.

The potential problem I see is that you could end up pulling both plugs from the same leg. You run the risk of overloading one leg if the pedestal can not support that much current.

This may be a better solution given your wiring situation:


This should pull 30 amps from each leg and you dont run the risk of overloading anything. Only downside is you can only run one AC unit if you are at a 30 amp only site - but I think you would have that limitation anyway.

Every 50 amp site I have been to also had a 30 amp plug and a standard duplex outlet.

Yea, as long as the RV park has a 50 and a 30 i would be okay, but you are right if only one 30 plug I would not be able to run the second A/C. The adapter you are showing now is the one I was talking about but was not sure if it would put 30 amps to each cord.

It should give 30 to each size, but obviously you want to verify that is how it is made. A 50 amp circuit is actually two 120 volt legs, each with 50 amps - so it is a lot of power and cover what you have with no problem.

You probably won't need both air conditioners at the same time. One AC seems to be enough up to 100*.
