Pre wire for EV charger

[slillie]

Debate is healthy, resorting to name calling is childish, surprised this is the route you've taken. This will be my last response to you on this topic.

To support my comment, I've had several instances in the past 8 years of EV charging, where my 32A mobile connectors will heat up to the point that the charge rate is reduced to 16A. This is using #6 AWG on a NEMA 14-50, which shouldn't even come close to being an issue with continuous charging over a period of hours (~4+ hours). Had this been an issue with one of my properties, I'd say its probably install related, but its happened at several (all located in differing states).

Sounds like an issue with your mobile charger, not the wiring between your 14-50 to the breaker box.

This is a small nuance, but it's relevant since the guide doesn't specify the conditions where #6 doesn't actually pass muster for a 60A circuit. When I was first learning about EVSE installation, I found this pretty confusing since I thought wire is wire. What's worse is that the code says that #6 THHN is good for 60A, and that's actually what's inside the NM (Romex) outer jacket!

THHN (Thermoplastic High Heat-resistant Nylon)…not the same as Romex. Sorry for the highlighting. Don’t know how to get rid of it.
