Ok...always heard them referred to as 120 volt plugs (30 amp 120 volt, and 50 amp 120 volt). Sounds like is is 50 amp 240 then. Thanks.
That said, she has power to her RV. She has a lamp plugged in that works. Slides don't work, one ceiling light (12 volt?) works. Most (all?) others do not work. Her Air Conditioning does not work. Cycled all breakers (main and branch), no help. Started pulling fuses and checking them, the few I checked were good, did not check all. Where do I head next? Does the DC have anything to do with the air conditioning (control?)? If the converter was dead...I would think the ceiling lights (all) would not work. But thinking I need to find/check the converter next.
