Has anyone had a NEMA 6-50 melt?

no reports that I'm aware of - but it should be no different for 14-50 vs. 6-50 socket - the 14-50's that have melted that I've seen all demonstrate thermal stress on one of the 120V "hot" connectors - which would be the same load/thermals on a 6-50 outlet.

Neutral is unused in the 14-50 socket - and is not even wired up in the 14-50 Porsche supply cable - so 14-50/6-50 supply cables are electrically/mechanically identical, with only variation in the blade pattern for compatibility.

Damn, I have a Leviton 279-500. Going to be such a pain to swap out, not fun manhandling 6AWG cable. Checked the receptacle and didnt see any stress/burns but usually charge at a DC station.

If you change it out be aware Hubbell takes a faceplate with larger diameter hole and deeper outlet box than "normal" 14-50Rs.

I saw that on amazon… $100 all in. Not looking forward to that project.

AT LEAST they plan on sending another update to preserve your set amperage. Regardless, I couldn’t stand the PMCC anymore so I recently installed a JuiceBox and omg it’s light years better. Instant connection and super reliable so far. It’s totally worth the extra few hundred bucks imho. Now I just keep the PMCC in the frunk as a backup when traveling.

I've been using the PMCC for 18 months at 40A with a Leviton 6-50 receptacle. Just checked it and no signs of heat stress. Still looks brand new.

The caveat is that my house was built in 2007 and I have 200A service.

Got the same email. I use my Tesla 220 v EVSE with a TeslaTap adapter (thanks to your advice DaveO) My question is the sentence saying not to use 110 v outlets.
Does this mean is I’m say visiting a relatives house I cannot use the 110 to trickle charge?

Yeah, me too. My gen 2 Tesla charger with TeslaTap adapter works flawlessly and charges my Taycan and my wife's Q4 e-Tron at about 60 miles/hour. My PMCC sits, unused since day one, in the storage space under the trunk.

If one uses 110V it will work - But takes 36+ Hours to charge.

Complete BS blaming the outlets. It's the cable between the EVSE and car.

I changed everything BUT the outlet (EVSE, car) and it's working flawlessly at 40 amps.

It's the cable between the EVSE and the outlet. The cable between the EVSE and the EV is fine.
