I just ordered my MY and I'm trying to get my charging situation setup. I bought my house from my parents and my dad had a woodworking shop with plenty of 240V hardwired to his equipment. There is an old hardwired planer on a 240V 30A circuit that I want to get rid of and install an outlet for my mobile connector with adapter. There are three wires coming out of the wall box (2 hot and one bare ground wire). I was planning to install a NEMA 10-30 receptible but the wiring diagram indicates 2 hot and 1 neutral wire. Is my ground wire essentially the same thing as a neutral wire in this situation or is this a mistake? Any help is appreciated.
