I am in the process of moving to a new house and had a 50 amp circuit with a NEMA 14-50 outlet installed there yesterday so that I can use my JuiceBox. At this house, the electrical box is on the outside wall, on the opposite side of the house from the garage. The electricians (from the same company I used before) ran the wires up through the attic, following an existing run. I'm not sure how much wire they used, but probably more than 50 feet. The total for this job was $1,031 (that includes an $89 service call fee- so $942 for the work). It took them a few hours to complete. The price was right in line with what I was expecting.
