1.04DEFINITIONS
A.CHARGING CIRCUIT INTERRUPTING DEVICE (CCID) – A device that continuously monitors the differential current among all of the current-carrying line conductors in a grounded system and rapidly interrupts the circuit under conditions where the differential current exceeds the rating of the charging circuit interrupting device. The device is identified by the letters CCID followed by the differential trip current rating of either 5 or 20 mA.
B.LEVEL 2 CHARGING – A method that utilizes dedicated a.c. EV supply equipment in either private or public locations. The vehicle shall be fitted with an on-board charger capable of accepting energy from alternating current electric vehicle supply equipment. AC Level 2 charging permits the vehicle to be charged by connecting to a single phase voltage of either 208 to 240 Vac.
C.GROUNDING MONITOR/INTERRUPTER – A device that monitors equipment grounding continuity in a charging system, and either prevents the circuitry from becoming energized under conditions where the grounding is not available or interrupts the circuit under conditions where the grounding is lost during operation.
1.05SYSTEM DESCRIPTION
A.Electric vehicle supply equipment (EVSE) for SAE J1772 Level 2 charging, rated a maximum of 250 V ac, with a frequency of 60 Hz, and intended to provide power to an electric vehicle with an on-board charging unit. This specification covers electric vehicle supply equipment intended for use where ventilation is not required.
B.EVSE shall be suitable for use on a solidly grounded power distribution system.
