Hi!
I have a Leviton J1772 charger at my office (208v). It says on the front of it that it is 40 amp. When I plug my car in, it charges at 30 amps. VisibleTesla shows the pilot current is 40 amps (attached screenshot of when charging).
Shouldn't the car charge at the full 40 amps in this situation? I understand when charging off a 14-50 or similar plug it uses 80% of the line capacity but I didn't think that applied to fixed-mounted EVSE's like this (or for that matter a Chargepoint or Blink unit out there in the world). I am using the J1772 to Tesla adapter. If not, shouldn't it charge at 32 amps (80% of 40) ?
Is there something wrong with the installation of this unit or is this normal?
Thanks.
