Mike, if I tested this outlet without a neutral, how would it look?

Would I get any reading at all for L1 to neutral, or L2 to neutral?

Seems like this is another good reason to always check the pedistal/plug before llugging in.

Wow, what an eye opener! Thanks Mike! I’m kinda surprised (but glad) this story didn’t start with a readers’ horrifying letter talking about how they plugged their RV (with 50 A service) into a NEMA 14-50 receptacle wired for a Level-2 EV charger or a NEMA 6-50 with an adapter.

I had a NEMA 6-50 installed in my garage for possible future use with a welder or EV. I also installed a NEMA TT-30R for use with my 30 A RV. I did not think about the case where someone with a 50A RV might someday go looking for a place to plug it in and think mistakenly they could use the NEMA 6-50.

Your article made me think that I should label my NEMA 6-50 outlet to make sure that any future user is notified that no neutral is present. I’m wondering what other readers are thinking who are closer to the real life situation as I have neither an EV or a 50A RV?

My local permit office is requiring that all new residential garages include a 50-amp, 240-volt service for a Level-2 EV charger, but they don’t specify that a neutral conductor is required. I’ve seen several recent EV charger installations that used a NEMA 14-50R receptacle without a neutral for this application. And at least one RV owner plugged his 50-amp coach into it with predictable damage to his RV’s electrical system. That install was permitted and inspected. 😫

I predict more mayhem!
