Insert the J1772 cable through a Cable Gland and assemble loosely into the RIGHT hole in the box.

Thread BOTH AC lines through the Ground Fault Coil (4-pin). If you are using the OpenEVSE 40A J1772 Cable, this is both the red pairs AND the black pairs.

Thread one AC line through the current-measurement CT (2-pin OpenEVSE Current CT) . If you are using the OpenEVSE 40A J1772 Cable, this is either the red pair OR the black pair of wires.

The Ground should be connected with some extra slack so if the cable is forcefully pulled the pilot disconnects first and ground last.
