Is there something special about the Nissan Leaf plug - like neutral is not supposed to be connected??
The EVSE still works fine on 110-120 but I dare not try it again on the 200 till the dealer explains what is going on. 50 amps could do some real damage to a human being.

I assume 25ft but I can't seem to find it listed anywhere in the specs.

My guess is because it's an RV park outlet. You theoretically could charge the car just about anywhere in the country.mxp said:Why is the NEMA 14-50P plug chosen?
It's nearly impossible to find a 40 amp plug and a 30 amp plug would be out of compliance for any charge period for more than 3 hours (by code you have to de-rate the plug 20% if it's in continuous use for more than 3 hours). That leaves the 14-50 plug as the obvious choice. The big plus is that they are as common as dirt and used in RV parks and campsites all the time. Most homes won't have one unless there's an electric range installed. It's becoming more common in new construction to include one in the garage for future EV use. Anything over 50 amps is normally hardwired to a breaker.Tsiah said:My guess is because it's an RV park outlet.

I'm guessing mxp might just be wondering why as EVs don't need a neutral, why the Leaf EVSE didn't just come with a 6-50 plug and to that I'd agree it's probably because the 14-50 standard is much more common than the 6-50 standard. Tesla also standardized on the 14-50 very early on so it's kind of a standard for higher-powered EVSEs.johnlocke said:It's nearly impossible to find a 40 amp plug and a 30 amp plug would be out of compliance for any charge period for more than 3 hours (by code you have to de-rate the plug 20% if it's in continuous use for more than 3 hours).

And actually a 14-30 plug with the neutral prong removed or not installed, will easily plug into a 14-50 outlet. Juicebox EVSEs used to come standard with a 14-50 plug without the neutral, allowing you to plug into either outlet. I believe the newest Juiceboxes come with the 50a neutral prong installed, probably a CIA thing so someone doesn't plug their 40a Juicebox into a 30a outlet. Juicebox is a lot more "UL" than they were at one time.smkettner said:I think for the US market Nissan could have gone with a 24 amp EVSE with 14-30 plug and let the customer use an adapter if needed.
Of course it should have also been compatible with 208v.

It is a NEMA 14-50 even tho the shadow makes it look like a 14-30.
Hello friends, I have sent the photo of the wall plate inside my parking lot and I have also bought the converter from Amazon, but when I connect it to the Nissan leaf adapter, then After a few seconds, the red light of the adapter will light up and the charging will stop Do you know where the problem is? Please help me, thanks
Thank you for your quick response, I checked everything and it's true that after 5 seconds the lights of the adapter will turn on like the picture below.پیشنهاد می کنم ابتدا زمین خوب را بررسی کنید. من می بینم که مجرای زرهی وجود دارد و باید زمینه را فراهم کند، اما گاهی اوقات اینطور نیست. مورد بعدی که باید بررسی کنید این است که بررسی کنید که پریز شما به درستی سیم کشی شده است، هم در جعبه خروجی و هم در پنل سرویس.
I would check to see if your Nissan OEM portable charger unit (EVSE) works by plugging it into at a NEMA 14-50 receptacle and try charging from it. If it works fine, then the problem may be with that Westinghouse adapter you purchased....converter from Amazon, but when I connect it to the Nissan leaf adapter, then After a few seconds, the red light of the adapter will light up and the charging will stop Do you know where the problem is?
