When we bought a Nissan Leaf 2 years ago, I assumed we would be a 2 EV car family eventually. I had an electrician install 2 - 240 Volt 50 amp outlets in our garage. The EVSE we bought required a NEMA 6-50 plug. He ran two 50 Amp circuits to the garage and put in 2 outlets (separate circuit breakers). I knew nothing about NEMA outlets then and now, I know slightly more than nothing. I do know that both supply 50 amps @ 240 Volts. The 14-50 has 4 wires (line 1, line 2, ground and neutral) and the 6-50 has 3 wires (line,1 line 2, and Ground). How difficult is it to change outlets to a 14-50, if that is what is needed. Would I find the neutral wire just capped off behind the outlet?
1) Should it matter from the standpoint of charging the car? I know I just have to choose the proper pug adapter.
2) Also, can I assume the Tesla wall charger must be hard wired to the wall, rather than have an option to plug into the outlet option, like my Siemens EVSE, should I choose to have a Wall Charger rather than just plugging the car into the wall?
