Single / Dual System
Electrical Connection
Single Sided Charger Connection
•
Two (2) appropriately gauged hot leads (refer to local electrical code)
•
One (1) appropriately gauged ground (green) lead
•
Electrical conduit per all applicable state and federal regulations
•
AC input power should be inserted through bottom of EVSE enclosure
•
Electrical connections shall be made as specified in this section
NOTE
For the dual units, two separate line pairs need to be connected from independent service
panel breakers of the appropriate rating. Each hot lead should measure 120VAC to ground.

Wiring Standard
3-wire (L1, L2, earth)
5-wire (L1, L1, L2, L2, earth)
For a 3-phase system, the 2 ports should be
distributed between 2 different phases
(e.g. L1 & L2, and L2 & L3)
To reduce the risk of fire, connect only to a circuit provided with the appropriate maximum
branch circuit overcurrent protection (40A, 50A, & 100A for 30A, 40A, and 70A output rating,
respectively) in accordance with the ANSI/NFPA 70 National Electrical Code. On a dual-port
charger, this circuit breaker is for each port.
