5. Installation
Follow these steps for safe and proper installation of your lampholder:
- Turn Off Power: Locate the circuit breaker or fuse controlling the power to the installation area. Turn it OFF completely. Verify that the power is off using a voltage tester before proceeding.
- Prepare Wires: Strip approximately 1/2 inch of insulation from the ends of the electrical wires (hot and neutral) that will connect to the lampholder.
- Connect Wires: Loosen the screw terminals on the lampholder. Insert one stripped wire end under each screw terminal. Ensure no loose strands of wire are exposed. Tighten the screws firmly to secure the wires.
- Mount Lampholder: Use appropriate screws (not included) to secure the lampholder to your desired surface through the pre-drilled mounting holes. Ensure it is mounted securely and stably.
- Install Bulb: Once the lampholder is securely mounted and wired, carefully screw in a candelabra base incandescent bulb (max 75W) into the socket.
- Restore Power: Turn the power back ON at the circuit breaker or fuse box. Test the light to ensure it functions correctly.
Note: Always ensure proper grounding if required by local electrical codes.
6. Operation
The Leviton Model 10028 is a keyless lampholder, meaning it does not have an integrated switch. Operation is controlled by an external switch connected to the circuit. Simply turn on the external switch to illuminate the bulb and turn it off to extinguish the light.
7. Maintenance
Regular maintenance helps ensure the longevity and safe operation of your lampholder:
- Cleaning: Before cleaning, always turn off power to the lampholder at the circuit breaker. Use a soft, dry cloth to wipe down the exterior. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the lampholder for any signs of damage, such as cracks in the housing, frayed wires, or corrosion on the terminals. If any damage is observed, turn off power immediately and replace the lampholder.
- Bulb Replacement: Ensure power is off before replacing a light bulb. Allow the old bulb to cool completely before removing it.
8. Troubleshooting
If your lampholder is not functioning as expected, consider the following common issues and solutions:
- Light Does Not Turn On:
- Check if the circuit breaker is tripped or the fuse is blown. Reset the breaker or replace the fuse.
- Ensure the light bulb is securely screwed into the socket and is not burnt out. Try a new bulb.
- Verify that the external switch controlling the light is in the ON position.
- Confirm that all wiring connections to the lampholder are secure and correct. (Turn off power before checking wiring).
- Flickering Light:
- Ensure the bulb is tightly screwed in.
- Check for loose wiring connections at the lampholder or the external switch. (Turn off power before checking wiring).
- The bulb itself might be faulty or nearing the end of its life. Try a new bulb.
- Burning Smell or Smoke:
- Immediately turn off power at the circuit breaker. Do not attempt to use the lampholder. This indicates a serious electrical issue. Contact a qualified electrician for inspection and repair.
