Re: Had new 220 outlet installed but get fault light

Probably a bad ground.

I initially tried plugging my 120VAC charger into with a 2 prong 120VAC socket! No workie! Needed a good ground.

I agree with others that a poorly-installed ground is the most likely cause. You’re pulling a lot of amps through a home circuit and the EVSE has a lot of fault detection to ensure the safety of the charging process.

That said, one other possibility from my own experience: you may just have a flaky EVSE. My original AeroVironment EVSE did throw faults on a newly-installed and tested circuit. After the installing electrician ran every diagnostic he could to verify the line install, I reported the faulting to Nissan. They had a tech come out to replace the EVSE under warranty and that was the end of my fault issue.

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.



The Electrician brought a more accurate Fluke tester and apparently the circuit is only getting 211 volts. I guess I need to call the electric company to turn up the juice

Is this a SFR or condo? Sounds like you might be on 208 service and that could be the issue.
Your electric clothes dryer and electric oven both operate at lower power level on 208.

Does your electric bill say 240 volt service?

ClipperCreek and most other L2 EVSE operate fine on 208 service.

Electrician only checked 1/2 of the installation.

What is the voltage from each hot leg to neitral? If hot to hot reads 211 and hot to neutral reads 120 then you are on a 208 line and the Nissan 240v Charger will not work.

If your hot to hot reads 211 and hot to neutral reads 106 volts (1/2 of the 211v) then call the power company and complain about low voltage.

Yes, Electric company confirmed 208 service in a cheap production home, now what?

Does it matter which Clipper Creek unit or will they all work?

If you have a friend with an electric range (should be a NEMA 14-50R for a newer one), you could try plugging in to that receptacle to see if the fault light still comes on. That should confirm that the stock EVSE is OK. Another alternative would be to drive to an RV park and try charging on a 50A hookup (NEMA 14-50R).

Sounds like you have a three phase supply though, so you'll likely need to buy another EVSE that works on 208V.

ALL CC L2 work on 208-240 service. But go ahead and call them to verify before you click and buy.
Customer service is very helpful.

Then it is just a matter of getting the right amp rating and plug to match. Call today.
