If you pull the cover off the breaker box, you will see a singular wire attached to the breaker. You should measure the amperage on that wire.
Now look at the MAIN breaker for the entire coach. You should see two wires attached to that breaker. One black and one red. Those are the two main legs. Measure each with just the AC’s running. The neutral leg is white, and the ground is green. You do not need to measure white or green.
Caution is the watch word. You are working with live voltage. Do not do this if you are not comfortable. Find a tech or friend who is.
Early in my coach days, I found a basic “how to wire a house” book was a huge help in understanding the basics of how a coach was wired on the 120 side. Learning the fundamentals of 120V wiring is a worthwhile endeavor for any coach owner.
When you open the breaker box cover, take some pics and post them here. Identify the AC breakers with a piece of tape or something.
