PEV Sub-Meter Socket Installation:
Refer to Figure 3 for a typical PEV sub-meter socket installation. The
installation involves a new 100 Amp sub-meter socket for the PEV car charging
station, supplied by a new breaker in the existing service panel. The sub-
meter socket should be installed as close as possible to the existing meter,
and a label stating “SUB-METER FOR CAR CHARGING STATION” should be placed.
Existing Service (OH or UG) should be 5 feet away from the sub-meter socket installation.
Customer Service Panel Detail:
Refer to the existing customer service panel for new wiring circuit details
for the PEV car charging station.
