Temperature rating of terminals on 14-50R

[darekelec]

Good afternoon. What’s the temperature rating of connections on 14-50R regular and for EV ?
Is it 75 or 60 ?

You would need to look at the actual receptacle. Most are 75C

Also there is no product standard for an EV receptacle at this time....while there are at least two 50 amp receptacles on the market marked EV, the design and specifications is totally from the manufacturer's engineers. One of the brands is simply their "industrial duty" receptacle that has been on the market for years, and simply rebranded as an "EV" receptacle.
UL 498 is working on a standard for EV receptacles so that the language in 2026 code that requires listed EV receptacles can be complied with.
