THANKS ! I did "enjoy" thatAndyH wrote:...But it's not up to the NEC.
To view the 'rules of installation' from one of the 'local jurisdictions' that adopted the guidance into law, enjoy this "ELECTRIC VEHICLE
INFRASTRUCTURE INSTALLATION GUIDE" from Pacific Gas and Electric:
http://www.pge.com/includes/docs/pdfs/a ... ehicle.pdf
It's from 1999, but page 13 (also page 20 on left-side index), says (in part) (color emphasis and square bracket comments are mine):
B. EVSE Used in Level 2 Installations
The code and regulatory requirements that affect Level 2 EVSE (apart from those listed in the
section on Level 1 EVSE) include:
* Overcurrent Protection: [... paragraph skipped ... ]
* Safety Switch: [... paragraph skipped ... ]
* Receptacle and Wall Plug: Where the EVSE calls for an in-wall receptacle, a 50 amp, 240
volt, 3- or 4-wire wall plug configuration is required. However, most charging equipment will
be directly wired, eliminating the need for an in-wall receptacle. Level 2 EV connectors are
designed so that they cannot be used with receptacles for other electric equipment, and the
EVSE is labeled “For Use With Electric Vehicles” (CEC §625.15, 625.16).
