Tesla Motors Club

I'm 4-6 weeks out from getting my MX (100D). For now I plan to wire a 14-50 receptacle (50 Amp breaker) because it is cheap (relative) and easy. At some point down the road I'm hoping to score a referral and get a free wall charger (or maybe find one on Craigslist or ebay - anybody out there ???).

Anyway, I want to size the wire so that when I do install the wall charger, the AWG will be sufficient to support the 90A breaker (72A charging). I'm guessing folks out there have done this. What gauge copper wire is required. FYI - the run from the panel to the wall charger is approximately 60 feet.

I'm fairly certain 2 AWG copper will work. How about 3 AWG copper?

Thanks-
