There's a high probability our garage will be the home of a Roadster and an S by the end of 2013. I'm charging 220 exclusively at the office right now, and would like to wire the home garage with a pair of outlets on one 220 line. Does anyone have any experience charging two cars on the same line simultaneously, particularly overnight? Obviously local codes may dictate otherwise, but is there any actual technical issue here, either with the electrical current or with the Teslas? My reasoning is I'm in a common garage area in a condo building, and wiring costs aren't going to be cheap, like adding an outlet for a freezer in your private garage adjacent to your kitchen. Literally might have to run 75 feet of conduit across and down from a 25 ft ceiling. If I can cut the install cost in half it would be great. The obvious workaround is to time one charge, for example, at 6p to 12p and the second from 12p to 6a, but that's not always going to be a possibility.
