5. Installation / Setup
This section outlines the general steps for installing the Leviton 85103 wall plate. Ensure you have read and understood the safety information before proceeding.
- Turn Off Power: Locate the circuit breaker or fuse that controls the power to the electrical outlet where you intend to install the wall plate. Turn off the power completely. Verify that the power is off using a voltage tester.
- Remove Old Wall Plate (if applicable): Carefully unscrew and remove the existing wall plate from the electrical receptacle.
- Inspect Receptacle: Ensure the duplex receptacle is properly installed and securely mounted to the electrical box.
- Position New Wall Plate: Align the Leviton 85103 oversized duplex wall plate over the duplex receptacle, ensuring the openings match the receptacle's slots.
- Secure Wall Plate: Insert the provided mounting screw(s) into the center hole(s) of the wall plate and thread them into the receptacle. Do not overtighten, as this can cause the thermoset plastic to crack. Tighten just enough so the plate is snug against the wall.

6. Operation
The Leviton 85103 wall plate serves as a protective and aesthetic cover for a standard duplex electrical receptacle. Once installed, it provides a finished look and helps to prevent accidental contact with electrical wiring within the wall box. The operation of the wall plate itself is passive; its primary function is to safely enclose the electrical device.
7. Maintenance
The Leviton 85103 wall plate requires minimal maintenance.
- Cleaning: To clean the wall plate, wipe it with a soft, damp cloth. Use mild soap if necessary. Avoid abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or material.
- Inspection: Periodically check the wall plate for any signs of damage, cracks, or discoloration. If damage is observed, turn off power to the outlet and replace the wall plate.
8. Troubleshooting
- Wall Plate Does Not Sit Flush:
- Ensure the electrical receptacle is properly seated and secured within the electrical box.
- Check for any obstructions behind the wall plate.
- Verify that the mounting screws are tightened evenly, but not excessively.
- Wall Plate Cracks During Installation:
- This typically occurs due to overtightening the mounting screws. The thermoset plastic, while durable, can crack under excessive pressure. Replace the cracked plate and tighten screws gently until snug.
- Missing Mounting Screw:
- If a mounting screw is missing, contact Leviton customer support or obtain a suitable replacement screw designed for wall plates.
