Wiring Color Code

Connect the charger to a single phase 120/240 volt, bonded neutral power source. All wire must be sized in accordance with the National Electric Code.

Wiring Diagram

Electric vehicle charging stations must be equipped with an internal Ground Monitor/Interrupter circuit (GMI circuit). For the GMI circuit to function, a reference to ground must be made through a main bonding jumper or system bonding jumper (located where the neutral connection is established and bonded to ground). Without the neutral to ground connection, GMI protection is not possible, and the charger will be inoperable.

If you have an electrical system without a neutral you must upgrade your electrical service from the utility or provide a separately derived system to effectively power and protect the electric vehicle charger.
