I am taking delivery of my X75D this afternoon, and my electrician is coming this morning to install my HPWC. (I know....nothing like waiting till the last minute! Today was the soonest my electrician was available.) My Model X does NOT have the 72A charging option. How should my electrician install and configure the outlet? I believe I have up to 100amps of service available. While I may not have the 72A charging ability in this Tesla, I want to provide the flexibility to have faster charging in the future if I ever get another Tesla with the faster charging capability. If some can please shoot me a quick response, I would really appreciate it! Electrician is coming in an hour and Model X is being picked up this afternoon. Thanks so much!
