@sickbones The cost to run your wire is mostly going to depend on the size of the breaker (ampacity of the circuit you want), gauge of wire (related to the breaker rating), and the distance it needs to run. I had my guys run a 50A breaker so I can charge at 40A, and I have an attached garage. My total run was under 20’ as I mounted the charger near the house wall - the wall charger has a 25’ cord, so from that location I can reach anywhere in the garage, and it is actually long enough that I can park on my driveway and still charge. Since the wire was being run inside the garage (not in the wall) we used armoured cable. The night before the electricians came, a buddy and I mounted the charger to the wall, so all the electricians needed to do was pop in a new breaker, drill through the rim joist into the garage, run the wire, and connect it to the charger. Saved some of the electricians’ labour costs. After they were done I spray-foamed and fire-caulked the new penetration.
I got a quote from a Tesla-recommended company, but they were more of a commercial outfit and had a checklist from Tesla that they were required to do, which included a load calc. Based on that it was going to be a couple grand and I would have been limited to a 20A circuit; since it was a Tesla recommendation they had to be very conservative, I assume to limit Tesla’s liability in the event the new install burned my house down. I discussed with that electrician and he agreed that unofficially a 50A circuit would be fine since I charge at night when there are no other loads present. My electrician agreed so we went ahead and did it, I’ve never had an issue. It was one reason I bought the Tesla wall connector; in case I was tripping the master breaker, I could dial down the current using the dip switches. Of course, you can also set the desired charging current in the car, but I like a hardware solution instead of just software.
Talk to an electrician that will come out and look at the install requirement in person, not just over email, and anything you can do to reduce their labour is going to save you money. Under $1,000 would be pretty reasonable for an install similar to mine, I would think - a few hundred bucks for materials, maybe three hours of labour for two guys. My guys were done in less than 2 hours and they’d never installed one before.
