Installed 240v outlet but Ford mobile charger shows yellow light

this picture shows the receptacle end, but not inside the panel. He may have wired ground to Neutral bus

Yes you may be right. Seems unlikely for an electrician to make that mistake, but it is possible I guess.

I doubt the EVSE would detect this as a fault, though. How could an EVSE test for this particular code compliance concern?

Both of those key sets are metric. Color has no determination on what kind of set it is.

Maybe not, I have mine grounded by a ground rod into the earth.

I'm not an electrician or an electrical engineer, but I think your approach is unusual and while trying to learn more, I found this interesting article:

I am not making any assumptions since the electrician didn't have SAE allen set to torque receptacle.

the charger MAY error out if there is continuity between N and G, I dunno. ground loops can be very tricky.

the OP can eliminate that by either looking behind the deadfront, or testing the charger somewhere else that has a known good outlet.

Is it, I don't know a thing about electrical till a week ago. Now I am learning

Look at the numbers. They are all mm. Standard will have fractions.

That is against code. You must have a grounding conductor going back to the main panel.

At the main panel the neutral buss and the ground bus should be bonded together and connected to an earth ground at the service entrance to the building. If this is not the case in this installation, then the Ford charger would not have an earth ground. Also if the panel is grounded correctly you would not need the extra ground rod connected to the charger. At my outlet there was an existing ground rod so I used it as additional grounding.

Yes, I have that also.

Yes, I have that also.

Gotcha.

my point is that we have not seen a picture behind the deadfront to see what the N and G wires from the outlet are bonded to. The ground wire we see at the outlet may, or may not, go back to Ground at the panel.

People, this won’t matter, this isn’t the problem, it will still work. Because neutral and ground are connected together somewhere, where the bond exists is electrically indistinguishable to the EVSE. It can’t know if you put the ground on the neutral or ground bus.

We now know the outlet is wired correctly from the photo. The EVSE is showing an internal error, not a ground fault. It’s defective EVSE. Case closed.

Bought this Allen wrench in inches (red) and it fits. Tightened it more.
Put everything back and same yellow light.

I am thinking it is the adapter problem.

Attached are the pics of writing(the wire coming from bottom left is the 240v, breaker is the top right 50 amp)

The volt meter shows correctly shows 120v for each outlet

you really should check between L1-N and N-L2 for 12v, and then L1-L2 for 240v.

But if I were you, and you have the panel open still, before you bring your charger to some other outlet somewhere.... vacuum out the wood chips, and just TRY moving the white wire to the Neutral bus.

I wonder how the electrician can leave the wood dust like that. Thanks for the tip.
