While I am waiting for Tesla email (sep18-Nov18 delivery) I am thinking about installation of NEMA 14-50 in my garage. Generally it should not be complicated as I am an engineer electrician myself, but in USA I work as a programmer and not familiar with codes. I see some complications in my case: 1. Electrical box has only one pole free left. I am thinking of using wire nut to join wires of two circuits and piece of additional wire to connect the to one pole and make one breaker free. Then I could remove it and I will have two poles available. 2. Electrical box is installed in between two vertical wooden stands, so I guess I can use only bottoms holes for the cable (all top holes are busy). 3. There is some kind of shelf bellow the box, you can see on a picture (where also you can see the hose), and it looks like it is made of plywood. I do not know if I may install NEMA 14-50 receptacle on that surface. The electrical box has 100A main beaker. A/C uses 40 two poles breaker. I will use my car not often, as I do not use it to my work commute. Actually for me even 120V charge will be enough, but I still like to have NEMA 14-50 just in case. What would you do in my case?
