So if someone wired up an RV outlet the same as a welder outlet, and plugged a 50 amp RV plug into it, what would happen? Nothing?

I know I've read about people plugging into an outlet at someone's house and frying their electrics due to running 240 Volts to their 120 appliances. Would that just be a result of the outlet being wired incorrectly, and have nothing to do with the wirer copying a welder outlet?

Am I laboring under a misapprehension here? I know that I lost one leg of my 50 amp service and then had some appliances, lights, and outlets not work.

Welder is usually 6-50 outlet and the 14-50 plug will not fit. There is only one way to wire a 14-50 outlet or plug to meet code and no harm will come no matter where it is located. Nothing special about an RV park or at home. Same, same.

Unfortunately the NEMA TT-30 (120v RV) and the older but very common NEMA 10-30 (240v) dryer outlet look similar. People seem to force the mismatched plug in on a weekly basis and burn up half the items.
