240 Volt Outlet Problem

[James Rovner]

I had an electrician install a 240-volt outlet in my garage for charging my 2024 Leaf

When I connect my OEM charge connector the power blinks and the fault light comes on.

I tried a different connector and a different Leaf and got the same issue

What can I tell the electrician to do to fix this?

Most likely a ground fault. esp if he didn't pull a ground wire and expected the conduit to be the ESG.

Electrician is the expert. Tell him what you told us and tell him to fix it. Its not your job to fault find!!

Find a different electrician

Another thought also comes to mind, this is a residence and not a condo right?
Some commercial buildings have 208 volt instead of 240 volt and the OEM EVSE will not work on that voltage, but aftermarket EVSE will.
208 volt is across two legs of a three phase wye supply. It would not be found in a residential single phase supply.

Good point, but you would think the electrician would have tested/verified the voltage at the time of "sign-off"...and I would have had him test it under load (e.g. charging the car).
Another reason to find a different electrician.

Almost all 240 stuff can be run on 208, so much so that most don't even consider it a problem. The Nissan provided EVSE seams to be the exception to the rule.
The OBC on the Leaf doesn't care, the EVSE does (for some reason), at least that is what has been reported on this site.
An aftermarket EVSE can be used if that is the source of the problem. Most work from 200 to 240 volts.

The owners manual shows how to determine what is wrong with the charging cable. It shows what the problem is with a combination of the lights being on, off, blinking or not blinking. Like others have mentioned there is a problem with the receptacle that the electrician installed.

Most likely a ground fault. esp if he didn't pull a ground wire and expected the conduit to be the ESG.

If he didn't bother installing a pesky green wire, I have to wonder what receptacle he used. OP might want to check. How would an inspector have overlooked a missing ground wire? And how do we know the electrician was a he?

In some jurisdiction it is permissible to use PROPERLY bonded EMT as the ESG (Ground). I am not in favor of this a pull a separate ground wire regardless, bonding to the metal box at every jct.
I was surprised to find this at my brother house. That said, I don't know nor have I looked up if there is a restriction on how large or what type circuits that it is permissible, as I said, I always pull a separate ground.
However, in his case, the lights may be indicating a ground fault, regardless of the cause, IDK because I don't have that Nissan supplied EVSE.

Guilty as charged, I am old enough that the male pronoun was commonly used.
That is not to say that a women can't do anything I can.
Nor is it a slight on any GBTQ person who also could do anything I can.
Old habits die hard.
I was refering in the generic form to whoever did the install, close enough?

Hi I would definitely say it an earth/ ground fault. Had the same problem using the EVSE with my 2016 leaf.
Had separate earth/ ground wire connected to the socket and back to the main earth/ ground point and all was fine.
Haven’t had a problem since.
As others have said get the electrician back to rectify the problem.
