50A EV Receptacle

[electrofelon]

There is an issue with multiple reports of failed receptacles for EV equipment. This really should not be happening as the testing in UL 498 accounts for a continuous load at the full rating of the receptacle, but something in the testing standard is likely wrong, so listed receptacles are failing in real world usage and they should not be.
The only dumb thing about this is that the approval requires the use of a product that does not exist and it may be a number of years until one exists.

I just don't see this as a NEC issue. I don't see why EV amps should be different than other amps. I vehemently oppose making this the electricians problem where they need to choose the "correct" receptacle for the type of amps it is supplying.

Should be product recalls not code changes. This what happened with the GFCI for dishwashers as well. Supposedly what got this requirement was some failing component on some models that tended to start fires when it failed, but GFCI would trip when that failure occurred. That should have also been a product recall issue and not a code issue, but manufacturers is looking for getting AFCI and GFCI implemented in about any place they can and pushing it to code members as much as possible

I would probably never omit the neutral on any 14-50 receptacle particularly in a garage or outdoors, potential for an RV to get plugged in is a big reason. If running raceway and not cable I'd at least run a 10 AWG neutral conductor over no neutral at all.

Omitting a neutral sounds like a lawsuit waiting to happen. Floating neutrals can do nasty damage to things on 120V branches.

product recalls not code changes

From what I've read, it's almost entirely Leviton's cheap trash 1450R that caused all the problems. That's 90% of reports/images I've seen. Recall and move on. Otherwise, making a receptacle that's 100% immune from occasional meltdowns is impossible, if you know any tell me I'll swap out my entire house tomorrow.
