While I agree that those leviton recepts are likely made too cheap, I conjecture that a large percentage of devices and electrical equipment would not hold up to 80% loading for very long in the real world.
Residential applications ( lighting, power, etc) are pretty forgiving. For the most part EV charging is about the only “demanding” load that there could be.
No copyrights on "useful articles" like electrical receptacles.
Note that a 14-50 is a 4 wire wiring device.
Yes, code compliant at the time. I have worked on a number of houses of this & previous time period. Even worked on re-wiring one older house on peer & beams that used the old ribbon type TV wire. While crawling under it, there was a piece of ribbon TV wire that I started to cut, but decided to wait, cause it might help me pull in a new TV wire. When I took one base receptacle out, the TV ribbon wire was attached to it!!
Would you please expand on "a level 2 charger" ? Does it have 2 different charging rates or what ?
Can I nominate the idea that a NEMA 14-50 receptacle can be protected by, oh, whatever the heck breaker size you want. Because well, stoves only need a 40A breaker?
Level 2 simply indicates 240VAC. They can range anywhere from 16 to 80 amps. Many can be adjusted. Those that operate at 40A or less can be cord connected and plugged into a 14-50 receptacle. If your customer is asking for a 14-50, his charger is a level 2. The post you quoted is confusing the issue.
The way I read this is that it would not apply to cord and plug connected EV equipment.
Thank you.
I'd prefer if this had read "passed EVITP" for any EVSE, or "EVITP L2" for level 2 chargers at 60 amp breaker size or less.
That was the basis of my NITMAM on this subject: by exempting cord and plug,
