4. Setup and Installation
Tools Required:
- Pencil
- Drywall saw or utility knife
- Screwdriver (Phillips head)
- Wire strippers/cutters
- Voltage tester
Installation Steps:
- Turn off Power: Locate the appropriate circuit breaker or fuse and turn off the power to the area where you will be working. Use a voltage tester to confirm that the power is off.
- Mark the Opening: Place the Carlon Old Work Box against the wall at the desired installation location. Use a pencil to trace the outline of the box onto the wall surface. Ensure the orientation is correct for your device.
- Cut the Opening: Carefully cut along the traced line using a drywall saw or utility knife. Ensure the opening is clean and sized appropriately for the box.
- Prepare Wiring: If new wiring is being run, feed the electrical cable through the wall opening. If existing wiring is present, gently pull it through the opening.
- Insert the Box: Push the electrical cable through one of the knockouts on the Carlon Old Work Box. Insert the box into the prepared wall opening. The swing-out tabs should be retracted or folded inward as you insert the box.
- Secure the Box: Once the box is fully inserted and flush with the wall surface, tighten the screws located at the top and bottom of the box. As you tighten, the swing-out tabs will rotate outward and press against the inside of the wall, securing the box firmly in place. Do not overtighten.
- Wire the Device: Strip the insulation from the electrical wires as required. Connect the wires to your electrical device (switch or receptacle) according to the device's instructions and local electrical codes.
- Install Device: Mount the electrical device into the Carlon Old Work Box using the provided screws.
- Restore Power: Once the device is securely installed and covered with a faceplate, turn the power back on at the circuit breaker.
