@Sandyjb, you mentioned that the ZenCar EVSE you purchased was 16A, was it this one?

A link to the EVSE you purchased from ZenCar would be really helpful.

Again if you have a volt meter, measure on your outlet the voltage between the two outer vertical slots(not the roundish one or not the center vertical slot) it should be 240v, if not it's the outlet, if it is 240v then it sounds like the plug on your EVSE is wired wrong. Does your EVSE plug even have the center vertical pin? As it's not needed for EVSEs I believe most of the time it's been removed on the plug, at least it was on my Juicebox EVSE.
As Wmcbrine said yes the neutral should be wired to your 14-50 outlet, just in case someone ever plugs in something other than a EVSE like a range, without the neutral you'd have no option for 120v that would be used by things like the range light bulb or clock or maybe even convenience outlet in the range. Note when I first wired my 14-50 outlet I didn't wire the neutral because I knew my EVSE didn't use it but I later added the neutral, which I think may have been code all along.

The EVSE Alozzy linked sure looks like my Ebusbar 16a L2 EVSE, I'm kind of surprised it came with a 50a plug, unless they were thinking someone might already have a 14-50 outlet and wanted a EVSE to plug into it.
Alozzy's 30a EVSE has the 14-50 plug and outputs 240v so they must know how to wire it :?

Super helpful guys! Seriously...cant tell you how much I appreciate in the input. Based on what you said above, I decided to pop open the charging plug to see the wiring. Pics are below.

Wiring....it appears to be one of the hots is not wired? Image

The red one is the non wired pin Image

Based on the above, do I basically just disconnect the green/yellow wire and connect it to the non wired pin?

Looks like they've got the neutral and the ground connected and only one hot. Weird.

Again though, which EVSE did you actually purchase from ZenCar?

Nice photos! Photo #2 tells it all, it's wired wrong :o
Green is correct as is RED but the BLACK should go to the other verticle pin, not the middle neutral pin!
Personally I'd just move it and also remove the middle pin(neutral) that the black wire is going to now, it's just not needed.
Just to verify, your EVSE does say it's capable of 240v? I'm sure it is but if for chance it says 120v only and you rewire it the way I'm saying......well lets just saying by rewiring it you WILL be putting 240v to the EVSE, just want to make sure it's truly a 240v EVSE :)

You could go through the hassle of mailing it back to China but truthfully it will probably only take you a few minutes to rewire it and it will be as good as new, it would take you more time to drive to the PO to mail it, kind of bad someone didn't know how to wire it though :? Of course they don't use the 14-50 outlet in China but it's still kind of unforgivable they made that kind of mistake!

Its this one (that I sent the link to zencar when ordering)
https://www.alibaba.com/product-detail/ ... 24679.html

Off their website, I assume its this one since the actual EVSE and J1772 connector look pretty much exactly like what I got.

NO! doing that would most certainly blow your EVSE!
Move the black wire to the unused pin :)
Leave the red and green wires where they are.

Yes the back does say till 240 50hz. Its the first thing we checked when the car was only getting 120.
Thanks so much for the quick turn around. Going to re wire it right now and see what happens!

Thank you! I always assume the black and white wires are the neutral/ground. Good thing Im not an electrician!

In the automotive world black is ground, in AC home wiring black is a hot as is red, green is always ground in the AC world.
