Installation Instructions
Important: All electrical work should be performed by a qualified electrician or in accordance with local electrical codes. Ensure power is OFF at the main breaker before starting.
- Prepare Mounting Location: Choose a suitable outdoor location for the outlet box. Ensure the surface is flat and stable.
- Disconnect Power: Turn off the power to the circuit at the main service panel. Verify power is off using a voltage tester.
- Mount the Box: Secure the steel box to the mounting surface using appropriate screws and anchors (not included, unless specified in package contents). The box features mounting holes for easy attachment.
- Select Knockouts: Identify the desired knockout locations for wiring entry (bottom, back, or sides). Use a knockout punch or screwdriver and hammer to remove the chosen knockouts. The box has various sizes from 1/2" to 1-1/4".
- Run Wiring: Feed the electrical wires through the selected knockout(s) into the box. Use appropriate weatherproof conduit fittings (not included) to maintain the NEMA 3R rating.
- Wire the GFCI Outlets:
- Connect the incoming LINE wires (hot, neutral, ground) to the designated LINE terminals on the GFCI receptacles. The GFCI outlets are pre-installed and pre-wired for ground.
- If extending power to another outlet, connect the outgoing LOAD wires to the designated LOAD terminals. Ensure correct polarity.
- Connect the ground wire to the green grounding screw in the box and to the GFCI outlets.
- Ensure all connections are tight and secure.
- Secure Gasket and Cover: Place the gasket over the outlets and then attach the metal cover, ensuring a tight seal to maintain weather resistance.
- Restore Power and Test: Turn the power back on at the main service panel. Press the "RESET" button on each GFCI outlet, then press the "TEST" button. The GFCI should trip, cutting power. Press "RESET" again to restore power. If it does not trip, consult a qualified electrician.
