The current Level 1/Level 2 EVSE supplied with the US Nissan Leaf fully complies with the current NEC, I believe.
Do ANY of the "EVSE Upgrade" Nissan EVSEs similarly fully comply?
Does anyone want to discuss the "pros and cons" of the safety aspects of NEC compliance for EVSEs?
The EVSE Upgrade that was done in April 2015 to my original Nissan unit kept when the 2011 was totaled essentially complies because it has a short cord (not more than 12 inches) with L6-30 plug and allows a maximum of 24 amperes on 208 or 240 volts. It allows a maximum of 12 amperes at 120 volts so an adapter for standard 15-ampere, 120-volt receptacle does not cause an issue except the overall cord length exceeds the 12-inch maximum requirement. The current settings can be set in 1-ampere increments from 6 to 24 amperes at 208 or 240 volts and 6 to 12 amperes at 120 volts if it is necessary to reduce the charge rate.
Personally, I disagree with that 12-inch maximum cord length requirement because it can be difficult to find a way to support the body of the EVSE so it doesn't hang by the cord. A 24-inch cord would be safer because it would allow the EVSE to rest on the floor.
Incidentally, the Nissan dual-plug unit works fine when plugged in to a 14-50 receptacle fed by 240 volts, but it will not work if the receptacle is fed by 208 volts. Most utilization equipment with 14-50 plug will function OK when plugged in to a receptacle fed by 208 volts.
