My apartment has a ChargePoint station with two connectors. One is a J1772, which charges at 208/30A very reliably. The other is a NEMA 5-15/20. I've had no trouble charging using the 5-15 adapter. If I try the 5-20, the station will trip an over-current fault after about 5-10 minutes. 12A charging is pretty painful, so I really want the 16A if I can get it. I've not tried messing with limiting charge current to find a sustainable current above 12A but below 16A.
I've contacted ChargePoint and they claimed they do see "GFCI trips" on their end. I found that explanation unsatisfactory, considering the station itself is reporting detection of an over-current condition. Could just be the support person has limited visibility into the faults themselves, though.
Has anyone else had similar issues with this type of station?
