And that worked! Now charging at 240 on both cars! Really....thank you wmcbrine and jjeff!
A quick rewire and things are working as they should. Baffled how they managed to screw that up! And so glad it was an easy fix.
Thank you again very much!

Great, congrats! And note if you ever want to make an adapter plug to plug your EVSE into a standard(20a) 120v outlet, you'd need a 120v male plug and 14-50 female plug. Wire the 120v black or hot(smaller blade) to one of the 14-50's hot, and wire the neutral 120v(wider blade) to the other 14-50 hot, finally the green or ground 120v plug to the green or semi-round 14-50s ground. You now know your EVSE is capable of 120v operation :lol: but note it will still be capable of 16a so if your car can draw 16 or more amps on 120v, make sure your outlet/wiring/breaker is capable of 20a use. 16a 120v charging will give you about 33% faster charging than your OEM Leaf EVSE assuming you have a Leaf with the 6.6kw charger and a 20a 120v circuit.

I actually have a Volt and 500e. The 120V was never an issue.....there are 2 120v chargers already with the car so I wasnt particularly concerned with getting more 120v charging. 240V was all I wanted and now I finally have it after more than 3 years of having a EV. Cant thank you guys for super quick turn around!

Re: Duosida EVSE Just Arrived.

Thanks for all the info in this thread, everyone. I've been investigating the same 240v / 16amp Duosida unit that others have. My only issue is around the plug options. At the location where I intend to use this, I have a 240v / 30 amp circuit available (served by two hots, a neutral and a ground). These EVSE units seem to typically come with a 10-30 or 6-20 plug, and I've also been offered a 14-50 plug. But there are issues with all the plug options:

1. 6-20 plug: As far as I understand, code for larger amperage outlets says that a receptacle must match the amperage of the circuit (there are some exceptions for stoves and such). This means that I can't go with the 6-20 plug, as this would require a 20 amp receptacle, which doesn't match my 30 amp breaker (and I don't want to change out the breakers at the box to make them 20 amp).

2. 10-30 plug: As far as I understand, most 240v EVSEs have two hots and a ground - no neutral. 10-30 receptacles have two hots and a neutral. So I don't understand how the 10-30 configuration is electrically sound. Does it bank on the neutral in the 10-30 receptacle being bound to the earth-ground back at the panel? If so, that seems a little risky, as my understanding is that the neutral wire is always capable of back-feeding electricity.

3. 14-30 plug: This would be ideal, as my receptacle box was built to recent code for 240v outlets and has two hots, a neutral and a ground. But nobody seems to offer this plug.

4. 14-50 plug: See #1 (can't have a receptacle that doesn't match the amperage of the circuit). I suppose I could order it in this configuration, and then remove the 14-50 plug and just re-wire a 14-30 plug onto it.

At this point I'm most inclined to go with the 14-50 and swap the plug for a 14-30. But I'd appreciate any other thoughts on the other options.

Thank you!

Is the receptacle going to be the only load on that 30 amp circuit? If so, the only NEC rule is that the receptacle rating be no smaller than the breaker rating. So you could install a 14-50 receptacle on a dedicated 30 amp circuit.

Cheers, Wayne

If you prefer the 14-30 option, you could just order a 14-30p on Amazon and swap the 14-50 plug out. Or buy an adapter cable:

While technically obsolete the 10-30 plug is still in millions of houses and you can still buy them. The ground is shared with the neutral but in your case you won't be using the neutral so that wire/pin will just be used for ground. While ground and neutral are generally separate at the outlet and wiring, they both attach to the same point inside your electrical panel, they are bonded together. If your not comfortable with that then just do as wwhitney said and use a 14-50 plug/outlet. Note if using a 14-50 outlet without a neutral you might also run into code issues. The 14-50 is supposed to have a netural and if you don't wire one and then someone down the line plugs in something requiring a neutral.....A better option for EVSE use is the 6-50 which lacks a neutral, unfortunately, very few EVSEs use that more fitting plug as the 14-50 is more likely to be found in peoples homes.
I'm not sure what kind of Leaf you have but if your Leaf is capable of more than 16a(3.6kw charger) I'd really suggest spending a bit more and getting the Zencar adjustable EVSE. They output up to 30a(27.5a in your case) and would make more use of your 30a service. Just get yours configured for a 24a option, you can pick up to 4 output settings. The Zencar is much nicer than the bare bones simple Duosida EVSE and still <$300.

You can get this for adapter for electric clothes dryers, if the unit has a NEMA L6-20 plug.

This one is a universal adapter from 14-50R to 14-xxP, cool!
