2nd A/C conundrum

[Stranger-ORO]

Let me preface this by saying I am in no way an electrician, I've replaced outlets, switches and installed ceiling fans. My friends do NOT call me "Sparky". This is pretty straight forward, or so I thought.

I'm waiting for the 2nd A/C to be delivered, so I thought I'd get started on the interior work over the bed.

I removed the valance and the screen. Took the blank box off and removed the backside, 3 wires, Black, White and Bare, normal. I made sure the circuit breaker marked "BAC" (assuming it meant Bedroom A/C). I know, assume... was off.

Anyway, my thumb brushed the Black wire and I felt a little tingle. "This is not good" I said to my self. I turned off the breaker marked "A/C" that turned off the rear A/C.

The wires I'm working with are still live. So, I flipped breakers one by one and the one marked "Micro" kills the wires in the bedroom. "BAC" kills the microwave. Micro is a single wide Mini breaker. BAC is a double wide. Both are 20 AMPS.

I'm thinking about opening the breaker box and swapping wires from Micro to BAC and so forth.

Any thoughts on this? Thanks in advance.

I'm trying to post pictures of this project but, I no longer have a working photo editing program. Any help would be appreciated. Thanks.

No photo editor required for posting photos, I think *.jpg, *.bmp, *.png, *.heic, and possibly other formats, are all acceptable for adding.

I am not aware of any 240 vac devices in RVs. That may not be true today though. A dbl breaker implies 240 vac (2 120 vac legs). That is assuming your RV is connected to a 50 amp service.

Suggest removing a wire from one side of the double breaker and see if the air cond line or microwave line only is still active. Then put that wire back on and remove the other wire to see if the other location is active.

If that works you can connect the appropriate wire to the microwave breaker.

The air cond on one side of the dbl breaker I believe will work but, if it were me, I would replace it with the appropriate single breaker and fill the vacant space with another, unused breaker.

Hopefully someone with more insight will chime in if this does not sound correct.

EDIT - Reread your post. Just swap the hot wires on the breakers. If the labels are on the power box and not on the breakers just swap the positions of the breakers. The dbl breaker should only have one hot wire connected. If it has wires connected to both screws then something else is going on.

Just move the labels. easy.

Those are double 120 volt breakers, 2 in a single slot. No big deal. Similar to 220 breakers that have a bar across the switches so you must move 2 at a time.

Ac should be a 20 though.

Well, the weather and my knee have finally cooperated so I can finish the install.
The good news is my height is 12' 10-1/2".
The bad news is the new unit, non-ducted, blows warm air on high cool.
Tomorrow I'm going to pull the plug for the heat strip and see if that changes anything.
Anybody have any other ideas?
