Just ordered a Model S and what to installed a NEMA 14-50. But for convenience was thinking of having 2 installed. I have a 3 car garage. I need at least 1 put in the center of the garage next to where I will park my car. But I might move it or I might get a second TESLA some day. The circurt breaker is on the same wall as the first NEMA 14-50 location which would not be used at first. Then from there need to run a wire to the middle of the garage for main location. I am just thinking the cost would not be much more to have two locations. Would this be a problem? Also, if in the future I get 2 TESLA's can I use both to charge both cars? I assume it would charge slower in that case. I understand that 2 Wall Chargers could talk to each other as an option. If that is required in the future could I easily convert the NEMA 14-50's to a Wall Charger(s) at that time? Or, should I put a junction box just instead the garage for the future and then run to the middle of the garage for now.
