Want to charge with my mobile connector at a vacation home that has a NEMA 14-50 outlet (see attached) . everything seems compatible but I notice that the outlet says 14-50 and 50A 125/250V ... and looking carefully at the tesla cable (came with car) on the inside of the plug it says 14-50 adapter then below that 30A 250 V. The plug configuration looks obviously compatible. I've used superchargers, have a Tesla wall connector at home and use Chargepoint at work, so have no experience with this configuration -- and just want to be sure there's no problem -- I'll literally be up in the mountains when I get to this NEMA 14-50! Any help greatly appreciated, tnx.
