It gave me two 30 amp/120V circuits, a neutral, and I plugged the ground wire into a nearby 120 outlet. Made sure it was happy with my 50 amp surge protector and circuit analyzer. Worked great.
There’s several versions of the 3-wire, 240 receptacles depending on amperage. I’ve seen 15, 20, 30, 40, 50 and 60-amp receptacles. I have a large chart of these variants, but I don’t see any way to post a picture of it in a comment. Should be in a future post.
Hi, I am the one that said you should show the welder diagram. It seems like now would be a good time to go ahead and show the full picture of the wiring back to the entrance panel and the risks.
I’ll do that on my next article covering this topic. I’ve drawn the schematic to include the wiring of the power company transformer which lets you see the service panel’s bonding and grounding paths more clearly.
WOW thats going to create a lot of havoc & damage in the RV parks! You know that eventually there are going to be RV & Level 2 EV chargers at the same pedestal! Hopefully they will be labeled or something to distinguish them apart other than destroying our RV electrical systems! Mike got any suggestions?
Visiting my brother we were able to park in his driveway and use his dryer outlet with this adapter:

Why does your pIC of NEMA 6-50P look like 15a/ 120V with narrow and wide blade and round ground?

All 50-amp 14-50 outlets in a campground should be wired with a neutral conductor, even if they’re intended to be used exclusively for EV charging.
Excellent point! I was not aware of the potential lack of Neutral on EV chargers. Keep up the great work.
I’ve seen a few garages wired for Tesla Chargers that had a 14-50 receptacle mounted in the wall WITHOUT a neutral.
