Had new 220 outlet installed but get fault light

Tue Oct 23, 2018 7:16 pm

I had a 220 outlet installed to charge my 2018 Leaf, but I get a fault light on the EVSE when I plug everything in...what’s up?

A couple of possibilities:
1. Wiring problem with new receptacle circuit (such as improper ground or lose connections).
2. Low voltage if you are using the dual-voltage Nissan EVSE that came with the car. It is documented in other threads on this forum that the Nissan dual voltage EVSE will not work on 208-volt circuits which are common in industrial/commercial facilities.

In either case, have the receptacle wiring and actual circuit voltage checked/repaired by a qualified electrician. The voltage should be about 240 volts if you intend to use the Nissan dual-voltage EVSE.

Yes measure the actual voltage between the hots, s/b very close to 240.
Then measure voltage of each hot to ground, s/b very close to 120 each.

Post the results.

You can start by looking at page 92 of the 578 page manual although I don't think it is very clear. My outlet has a little over 240V between the two opposing vertical slots in the outlet and a little over 120V between each of those slots and ground, the bottom vertical slot.

I wonder how many people have multimeters these days? Mine must be 40 years old.

Everybody should have multimeters nowadays, they are so cheap.... They even give them away at Harbor Freight stores...

The Electrical contractor says it could be a bad ground from the main ground wire within the foundation. When I plug the EVSE in the outlet the power light indicator is on, when I plug it into the car the normal activity starts and only after about 10 second the EVSE goes to fault.

So it could, but I'd be more suspicious of the new work than the old work.

You can get a ground tester cheap. You can also just use an electrician's test light and test between Hot(s) and Ground. If the light is strong and unwavering the ground is likely good.

EVSE has no idea where and how the ground is connected. EVSE may check voltage to the hots and that is about it. If there is a neutral it may check neutral/ground potential and continuity but most L2 EVSE has no neutral.

Have the handyman check the voltage potentials and post right here.

Most EVSEs leak a little current to ground to test during initialization. A poor or disconnected ground can be detected this way. I find it much more likely that the electrician goofed his install rather than the house ground being bad.
