Likewise, it is often difficult (or impossible) to determine if a particular "home" socket is on a 20-amp breaker, or 15-amp.
Although 16 amps from a 20-amp breaker is allowed, it would "trip" most 15-amp breakers.
So, the "included" 120v EVSE might be "set" to tell the car "12 amps max.", not 16. Or, there might be a user-setting on the EVSE (or in the car) to select the 12/16 current-draw setting?
The EVSE is also supposed to contain a "GFI" type function, I believe.
I believe over with the "other" car, GM has stated there is a setting at the connector on the 120v pluggable cable they will provide with the Volt. I would rather expect to see the same thing on the one Nissan gives us. (It might even come from the same company!)
Yes, ground fault interruption is required by code to be embedded in 120v EVSE pluggable cable. But DaveinOlyWA may still have an important point. I didn't realize that all garage and outdoor circuits had to be 20A and GFCI. If so, there might be less call for running on 15A than we thought, especially since it appears that use of extension cords is not legal.
But there still would be the issue of sharing a 20A garage circuit with tools in the garage. Wanta use your Skilsaw while your wife is sanding a dresser the easy way and the Leaf is charging? (OK, so I haven't seen a real Skilsaw for decades, but you know what I mean - a plug-in portable rotary saw.)
