as a gentle reminder that if you're using the PMC+/PMCC please make sure you have it paired/installed with the appropriate hubble NEMA socket - if you don't have a hubble socket - you should consider:

• turning down your PMC+/PMCC to 32 amps or less
• getting a hubble socket installed before returning the PMC+/PMCC to maximum power 40 amps (9.6 kW)

no new information here - just a bump/reminder - we had a community failure just this week - with a PMC+ that actually caused socket melting…so it's not theory that it might happen - it does happen - and the PMC+/PMCC power supply cables get hot enough in normal operation to thermally stress cheap/wimpy/lesser plastic NEMA socket into thermal fatigue leading to eventual failure - the PMC+/PMCC demand a commercial/industrial grade NEMA socket - porsche's document has the correct part number.

again just a reminder because we had a failure this week witha cheap NEMA socket - and porsche seems to feel their nominal operating temperature of 90-100F + ambient temps is "just" fine - it's your crappy socket that's the problem not our hot-running EVSE…

so please consider eitehr running your PMC+/PMCC "slower" or get the hubble - anything else is just begging for eventual failure (or get another EVSE that doesn't run quite so hot).

Porsche just issued a recall for their EVSE - this is the same recall for VW/Audi - and makes 100% sense since the EVSE's are IDENTICAL other than the stickers on the units.

says we get new power supply cables mid-2024 w//thermal sensor - it's unclear if they are upping the wire gauge or just adding a thermal sensor so the cable will tell the EVSE to shutdown mid charging cycle leaving your Taycan partially charged over night.

I prefer:

1. thermal sensor
2. 6 gauge wire

that would add the safety of a thermal sensor
and lower the nominal operating temperature when running at full 9.6 kW charge rate

this all makes sense given the upcoming high-volume EV MacanEV releaes - going to market with their current EVSE's with the known problems was not going to be pretty in my opinion.

it's taken them 3 years - but oh well…

Tesla Gen3 Wall Charger w/Powersharing setup - example here - https://www.taycanforum.com/forum/th...9/#post-290467

Tesla Gen3 Universal Wall Chargers are about the best $600 EVSE in North America right now…hard to go wrong.

Chargers are weatherproof, Keep in mind 50amps is a large conductor so try to stay close to your panel. I would make an effort to keep it protected from weather if possible even though its weatherproof.
