So just got my i-Pace. I don't get the 50AMP circuit done until Monday. No worries I'll just use the included charger. I've tried two different 20 AMP circuits. The charger immediately trips the GFCIs when the light goes green on the car. If I get creative with extension cords and plug it into an old non-GFCI outlet inside the house it doesn't trip and it appears to charge. Bad charger? Or are these normally this finicky?
Cant say i tried the level charger on gfi circuit. It works fine on just a regular socket in my garage. I do have a gfi circuit that gets tripped though with everything i plug into it - setup wrong. Do other things work properly from your plugs?
Poking around the EV forums for Bolts and Leafs this does come up from time to time. Sometimes it's the GFCI. Other times it's the charger. I'm less concerned about my house since I'll have the brand new 2020 version of Juice Box 40 up and running Monday. I'm more concerned if people have run into this trying to plug this into 120v outlets while on the road?
The first GFCI I tried was just installed Thursday by an electrician when I updated my panel to 200Amp service. It's likely a cheap builder grade CFCI. I could likely ask them to put a commercial or hospital grade one. But any house or renovation done in the last 10-15 years will have that builder "quality" of GFCI in the garage or outdoors.
In the meantime a closer look at the charger showed it's just a 10 amp device. So I plugged it into a non-GFCI 15A circuit and it seemed to work just fine.
It is rathe common with EVSE/cars dumping a spike current into ground on start of charging. For example early EVSEs (even Simons) would fault because of this with the Tesla Roadster. Over time they have changed how they trip to allow the initial ground spike and not count it as a problem. GFCIs are a pain and I am sure they would trip always. Heck my GFCIs trip sometimes when I turn on the lights!
So it doesn’t necessarily mean there is any issue. I have never plugged a 110 into a GFCI circuit, so can’t help. But I’ll do some tests at home and report.
Same thing happened to me when I first got the car. My house was less than a year old and passed all required inspections, so it wasn't a wiring issue. It could be the amps on the breaker for the GFCI outlet is below the spec required. I didn't bother to figure it out because I was getting the ChargePoint installed. I haven't thought about it in a couple of months.
