So here's my dilemma... I have a Model S showing up in a month or so which will only have the 48A charger, and I have a Model 3 hopefully showing up sometime later this year that I'm assuming will also be a ~48A car. These charging rates will meet my needs easily, since I rarely drive more than about 100 miles in a day. I've survived just fine with a LEAF and a 20A EVSE.
I have two wall connectors ready to install, and the nerd in me wants to just max them out with 100A wiring to future proof things. This will of course be more expensive and more complex to install. I'd need to run conduit for the wiring since NM isn't an option, and I'd have to architect it all around Power Sharing since I can't run two individual 100A circuits from my total 200A household service.
For 50A wiring I could just run some 6/2-NM through my crawl space and be done with it. I'd get 40A to the car vs. the max of 48A, but I'm sure I could live with that just fine.
Is there any reason at all to bite the bullet and install for 100A? Barring any future cars being massively LESS efficient, I just don't see a reason for me personally.
Is my logic sound?
