I'm a rather late reservation holder (9,500) that is counting the costs for the Model S. Maintenance, delivery fees, electrical work, etc are all starting to add up, so I'm trying to cut back where I can. Which brings me to this question: My garage has already been wired by the previous owners with a NEMA 6-20 outlet. ( I am not an electrician, I googled the plug to see what kind it was!) My electrical panel has 2 20amp breakers, connected together with a piece of plastic. I'm not sure if that means i have 40 amps on the circuit? I'm curious if this plug would be sufficient to charge the Tesla, and I can perhaps get out of re-wiring my garage? Seems like there are a lot of knowledgeable folks here, so I thought I'd ask. Thanks!
