After putting down my depost on a Model 3 last year, I called around to a couple of places to get estimates for installing two NEMA 14-50 outlets in my garage. I received an estimate of $1650 for the work. That seemed outrageously high to me. This morning, I finally ran out to Lowes, bought $300 worth of hardware, and got started. Here I have one outlet completed, and the box mounted for the second one. I've since finished both outlets, and have big, thick 6/3 NM-B run through the basement rafters all the way to the breaker panel. In the next day or two, I'll finish wiring them up. Then I guess I need to buy a 240v EVSE so I can use these outlets to charge my Leaf while I wait for the Model 3.
