Makes me want a 50 amp adapter that allows me to only use one leg or the other so at least I can pick the good side even if it cut total amps down to 50 instead of 100. I can run both a/c's off single 50 amp along with say a microwave for a little while.

This reminds me of a problem I had at a COE a few years back, one leg of the 50a had a breaker going bad and it happened to be the leg that powers my PD HW50C protector so I kept losing all power occasionally.

Thankfully the 30a connector at pedistal was on the good leg and i used it till the electrician could come out, just like the adapter you posted would allow to do. Until then I never realized or thought where the protector got its power from so at least I learned something good.

I worked at a campground in NW FL. Occasionally we would get complaints from people with EMS units that they couldn't get to work. I discovered that although the 50A receptacles were technically grounded via metal strap at the mounting screw, it required an actual ground wire from the receptacle to the GND block to work correctly. Our electrician could not explain why this was.
