Second week since i purchase my model s 70D. I had an electrician install a 240v nema 14-50 outlet and he used a 40amp breaker. However, i notice i'm going getting 32A from the outlet. My buddy used a 50amp breaker and he's getting 40amp. my breaker is not tripping and I'm just curious why i'm not getting a higher Amperage. The electrician is coming back to put in a 50a breaker but thought i would put this question to the forum. Your thoughts?
