Tesla told me to order the wall charger from the model S page. I ordered two, one for home and one for the weekend house. I was going to wire them for 80 amp, max 60 amp charging based upon the information on the MX. Much lower cost than wiring for the full 80 amp charge if not necessary. Today, a tesla rep said that the "single" charger on the MX was the "gen 3" charger and would draw up to 72 amps. Any info on this? I need to get moving on installing chargers but would hate to do it wrong, either too little or too much. Anyone have any additional info?
I think you've likely got just as much info on the Model X charger as anyone. This is the first we've heard of 72amps but that would be much more in line with Tesla trying to innovate. Given your particular situation it might make sense to wire for 80amps in order to get the max draw. They really should be able to tell you more. Also, is 72amps one of the outputs the HPWC is able to provide?
