I'm close to pulling the trigger on a new Model S, but I have concerns about getting a charging station installed. My Tucson house is older (built 1969, and the primary breaker box is a looong way (150+ ft) from the garage. I don't know the rated service capacity of the breaker box. I'd prefer a HPWC, but will settle for a NEMA 14-50. I'm not going to do the work myself. Can anyone recommend a good electrician for this kind of work, preferably one who has done a HPWC installation?
