We have a 1989 Winnabago Superchief and need some help. When we run the generator both our roof top air conditioners work but....when we are plugged into our 30amp only one at a time will run. Does this mean we need a double amp??
Thanks for any and all assistance. You can post your answers here or at upde32@yahoo.com
Thanks again!!

Hello 'updegraff',

Welcome to iRV2, we're really glad to have you here as a new member and are looking forward to reading your posts about your RVing experiences and adventures in your 1989 Winnebago Superchief. You'll find a great bunch of folks on this site who are very knowledgeable of RVing, the rigs we use, and the places we go in them.

Presumably, by the wording of your post, your coach is wired for 30 amps rather than for 50 amps. Running two AC units on 30 amps along with other stuff such as the converter may be electrically impossible in your coach. Some folks are able to use them both successfully on 30 amps by managing when the compressors start and run.

If your coach is a 50 amp unit and you're using an adapter to run it on 30 amps your solution is simple. Plug into a 50 amp receptacle and you should be good to go.

As you'll see, they're eager to help and share their knowledge and experiences with others.

Again, welcome to iRV2, we're glad you joined.

You probably have a 6.5 KW generator set which is ample to run two roof airs. Most coaches of the 1989 vintage only have a 30 amp service which is suitable for one of the A/C units of that vintage. You should have a switch some where in the coack that lets you select front/rear or both while on the generator.

We had a 1989 Pace Arrow and I separated out the rear A/C in the generator and wired it such that I could run one or both as it was designed or plug in a separate 20 amp plug and run it to the power box. if you are not electrically inclined, you need to be sure and inlist the aid of an electrical and make sure the separate unit is protected by a circuit breaker and the plugs are not live on the exposed ends. I used a special recessed locking plug and receptical in the generaor bay.

Updegraff, welcome to iRV2.com. We are glad to have you join us here and we look for ward to reading of your advenntures and experiences. Good luck on modifying your electrical service if you so choose. This is one big advantage of a unit with 50 amp service. Good luck and take care.
