Chris with Coastline Electric in Santa Cruz. He installed my HPWC in my Garage. He did the breaker work, was able to use existing conduit, dug a small trench in a planter area, punched through the wall with conduit, and mounted nice on the inside, put dirt back neatly, cleaned up nice. We walked through the test dip switches so I could see that it worked per the HPWC's instructions. He was half the cost of the company that Tesla/Solar City sent out to bid the job, and they weren't going to do any clean up/finish work.
