30 vs 50 amp electrical issue help

Well, the plot thickens. I just got off of the phone with Heart land I asked them to look up my build based on VIN.

They told me that my trailer was supposed to be shipped with the 50 amp cord that I have but that there is supposed to be an “adapter” between cord and trailer. He stated that the trailer itself is 30 amp but when I told him that I want to run a second AC he said that will be no problem at all.

I asked if this is some kind of hybrid between 50 and 30 and he said yes exactly.
So everything in my trailer is 120v…. And it’s 30 amp but supposedly I can run 2 ACs?

I was hoping for clarification but this makes the whole thing even more convoluted.

I talked to my sales guy and he said that was the craziest thing he’d ever heard, I don’t know much but I have to agree with him!

so, I can't remember if you posted what breakers were installed or any pictures of your ends of your cords, were all kind of speculating now.

but this could be right, and it could be a prep for the future install. the only difference between a 30 amp rv and a 50 amp rv really is the wires from the outside of the rv to the fuse panel, the breaker size, and sometimes the size of the fuse panel its self, but not always, after that there the same.

if they put a 50 amp cable on and put an adapter that only uses one leg of that power supply then that's fine, inside they may just have one wire taped off and not connected but in the area so when you do install your second AC they just have to hook that leg up with a 50amp breaker in the RV and it will put that second AC on its own leg so it won't compete with the first AC. Personally, I wouldn't have worried about the adaptor, and I would have just wired it up with 50amp cable on the 30amp breaker and left one pole off and isolated. You can have a smaller breaker one a larger feed for now with no issues as the breaker is to protect the wiring and that's just over protecting it from drawing too much. Then later you just change out the 30amp breaker for a dual pole 50amp breaker and hook the new AC up and away you go.
