It requires a 4-wire outlet with a separate neutral and ground so the electronics can run off of 120v while the car uses 240v. That means you can't run it off a 10-30 or 10-50 which only have 3 wires (2 hots and a neutral). You need a 14-30 or 14-50, or the specified L14-30. Making an adapter to run it off of 120v should be pretty easy, though.
Thanks for the responses. I was afraid of that answer about the Nema 10-50; I pretty much knew that was going to be the answer, but asked anyway. I'm not sure I can change the wall outlet and the plug on the tankless/instant hot water heater without raising too many eyebrows, but I might be able to, I will look further into it. There is a 480v Nema L14-30 even closer to where I park for a welder we have. Too bad I can' use that!maini wrote: 1) Yup a AWG 10 will work great
2) Use anything which has 4 prongs.. it will be fine.. just make sure you match the socket and plug properly
3) You definitely need Neutral as the EVSE checks for Ground before beginning to charge the car. It does not need Neutral to charge but needs neutral to run the EVSE circuit (as pointed out by all the EVSE circuit runs on 120V hence the need of one hot and the neutral). So you need to make modifications in your wall sockets if possible.
4) Keep the length of adapters 1-2 feet max.
L2 will change your life and the overall efficiency of your charging goes up a lot more.. you do a lot of service to yourself and the environment by moving to L2 charging
