I'm on the board of a small company in NY that I visit for a day or so monthly. It's 200+ miles away and I stop to supercharge, but it would be nice to be able to destination charge on more than a 120v plug. They have this plug in the loading dock which the maintenance guy tells me is 240v@60A. My questions for your collective input please: 1) Is anyone familiar with this plug, know what it's called and used for and can confirm the output? 2) Does Tesla sell a UMC adapter for it? 3) if not, any ideas how to plug in? Make an adapter cable? 4) If it really is 60A, how fast will it charge - and at 48A? 5) Other things I should be thinking about? Thanks in advance.
