Installing 2nd AC

[costello]

We have a 34 ft Georgetown with one ducted AC located in the front portion. There is a breaker for a 2nd AC in the breaker panel. Does this mean it is wired for a 2nd AC in the rear? And, the wiring may be located at the bedroom vent?
So, if I just want to put in a separate unit not tied into the existing AC ducting, use control knobs on the unit, and
the wiring is there, I could select a unit, take out the vent and perhaps without too much fitting, install the 2nd unit?

I've already installed a Winegard Trav'lr sk-swm3 satellite myself on this RV. The AC install looks easier.

Do you have a 50 amp double pole breaker or 30 amp double pole? The end of your cord will have 4 prongs if it's 50 and only 3 if it's 30. If 50 you should be all set to go because the wire is most likely roughed in to the back opening. A self contained without ducting would be fine to use. Just make sure the ducting to that opening is closed off.

Each A/C runs on a dedicated 110v circuit. No 50 amp breakers. The ducting should already be in place in the ceiling. You do need 50 amp service to your rig to support two air conditioners.

The panel in my coach has a 50 amp double pole for the Main. Each AC unit is on a 20 amp breaker. 50 amp is centered in the panel and the breakers are on each side of the double pole. 20 for AC #1, 20 for WH, 20 Receptacles on the left and 20 for AC #2, 20 for Microwave, 20 for GFIC Protected Receptacles on the right.

Good point. You are correct that the msin breaker is 50amp. I should have clarified I was talking about the breakers for the AC units.

Looks like you have the wiring all setup. The install is pretty simpe.

Yup, pretty simple. I recently installed a second air on my 5er, and it was pre wired for the 2nd. It has a thermostat already installed so the hardest part was getting those little wires connected to the right wires at the AC unit.
