I have 220v service to a box in my garage. It's served by a 4 wire setup (two hots, a neutral and a ground). I want to be able to charge my electric vehicle from this location. The EVSE (ev charging cord) that I'm going to use comes with a 10-30p plug, which requires a 10-30r receptacle. This receptacle only takes 3 wires.
Forget about all of the EV stuff for a second - essentially I need to install a 10-30r dryer receptacle in a location that's served by 4 wires. In my research on how to wire this up, I understood that the right thing to do in this situation is to wire the two hots and the ground, and leave the neutral wire capped in the box. However, the instructions for the receptacle state that I should use the white wire (neutral) and the two hots. Which is correct?
