This may be old hat to many of you but is it common for campground NEMA 14-50 to be 120V? I stopped at my first KOA and was disappointed to find the old style UMC 240 did not work. When I pulled out my meter it appeared that the plug was only 120V. If I measured between the two hots the voltage was 0 and 120 between a hot and neutral. I tried several sites with the same result.
Now the really quirky thing was I later stopped at a second camp ground and again they only had 120V NEMA 14-50 and my UMC 240 worked. The display on the Tesla said 240V and 30 amps but my meter said 0 volts between the hot legs and 120V between a hot and neutral. Was I just over tired and made a mistake or can the UMC 240 use a split legged NEMA 14-50 and charge like 240?
I had installed my own NEAM 14-50 for charging in my garage and I had just thought all such plugs were 240V. But in looking at several old posts several other have seen NEMA 14-50 at 120V.
By the way both campgrounds said they had NEMA 14-50 but had no idea if it was 240V.
Thank you
