Step6:
Install the UF Cable Connector 1/2 in. Cut the
insulation and strip the wires like the photo
depicted. Refer to the wire size selection table
below for sizing. Tip: Run cable inside grounded
conduit pipe for improved durability and safety.
Step7:
Use the wire connectors to twist the
connections in place.
1. Connect the Yellow/Green wire from the
Straight-Harness to ground. Ground is the
exposed wire without insulation.
2. Connect the Brown wire from the Straight-
Harness to Hot.
3. Connect the Blue wire from the Straight-
Harness to Neutral.
Step8:
Close the outlet box with the cover to provide a
weatherproof seal.
Tighten the UF Cable Connector and the Cord
Grip Connector to provide a weatherproof seal.
Reconnect the T-Harness with the Straight
Harness. Restore power to the circuit.
