I've seen a few other posts on wiring, but still have questions.
First and foremost, I'm not sure what difference it makes having a NEMA 6-50 outlet rather than a NEMA 14-50 outlet, if any. I currently have a NEMA 6-50 outlet because it is what my GE WattStation required. I wired it with 6/2 copper wiring. From the panel to the plug is right at 40 feet. It currently has a 40 amp breaker on it.
Tesla does have a 6-50 adapter. If I buy a Tesla and want to plug into the NEMA 6-50 outlet I already have, I know I would need to buy the 6-50 adapter from Tesla, and I think I would also need to upgrade the breaker. What size breaker should be used? I'm also unsure whether or not I would need to upgrade the wiring. Is 6 gauge sufficient or should I change it out for 4 gauge? Other than buying an extra adapter, is there any downside to using a 6-50 instead of a 14-50?
Thanks for any thoughts.
