I found them on the Tesla website and glad I called! Joey returned my call on the weekend and even walked me through the permitting process with the city of phx. They were able to come next day. David was very experienced with installing 50A outlets for Tesla cars with many installs under his belt! Because of this experience David was in and out in a single visit in less than 2hrs, very polite, clean and straight, and swept up after! Everything was done with a perfect fit and finish. I recommend them to all Tesla owners!
