I might be buying an electric car soon and i was wondering if I could use my current nema 10-50 dryer plug for my 240v evse? The plug is not used since I have a gas dryer.
The receptacle was installed by the previous owners, it was run through 1/2 inch emt conduit from the main panel to the dryer (roughly 25 feet total run). I read nema 10-50 is supposed to have hot-hot-neutral, but it looks like this has hot-hot-ground since there is a red, black, and green wire (also verified at the main panel).
Can i safely convert this to a nema 6-50 receptacle since i've read nema 6-50 should be hot-hot-neutral anyways? The current circuit has a 30amp breaker with 10 awg cable for the two conductor wires and 12 awg for the neutral (green) wire. Is this wire gauge safe/code for 30 amps? Should the ground cable also have been 10 awg vs 12 awg? The evse is only 16 amps but i'd want to know the plug is safe for 30amps. Sorry for the long post and thanks in advance!
