Installation and Setup
Follow these steps for proper installation of the Leviton 2460 Receptacle:
- Turn Off Power: Locate the circuit breaker or fuse controlling the circuit where the receptacle will be installed. Turn it OFF. Verify power is off with a voltage tester.
- Prepare Wires: Strip approximately 1/2 inch (12-15 mm) of insulation from the ends of the circuit wires. Ensure wires are clean and free of nicks.
- Connect Wires: Connect the circuit wires to the corresponding terminals on the receptacle. This L20-20R receptacle is a 4-wire, 3-phase, non-grounding device. Refer to the wiring diagram provided with your specific electrical system documentation for correct phase connections. Ensure all screws are tightened securely to the manufacturer's specified torque.
- Mount Receptacle: Carefully position the receptacle into the electrical box. Secure it using the mounting screws provided. Ensure no wires are pinched or damaged during mounting.
- Install Faceplate (if applicable): Attach the appropriate faceplate or cover to the electrical box.
- Restore Power: Once installation is complete and all connections are secure, turn the power back ON at the circuit breaker or fuse box.
Operation
To use the Leviton 2460 Locking Blade Receptacle:
- Insert Plug: Align the blades of the mating L20-20P locking plug with the slots on the receptacle.
- Twist to Lock: Insert the plug fully and then twist it clockwise (typically 1/4 turn) until it locks into place. You should feel a positive engagement, and the plug will be securely retained.
- Remove Plug: To remove the plug, twist it counter-clockwise to unlock and then pull it straight out from the receptacle. Do not yank the cord.
Maintenance
Regular maintenance helps ensure the longevity and safe operation of your receptacle:
- Periodic Inspection: Annually inspect the receptacle for any signs of physical damage, such as cracks, discoloration, or loose connections.
- Cleaning: If necessary, clean the exterior of the receptacle with a dry, lint-free cloth. Do not use liquid cleaners or solvents. Ensure power is off before cleaning.
- Tighten Connections: Periodically check and re-tighten terminal screws to ensure secure electrical connections. Turn off power before performing this check.
- Environmental Conditions: Ensure the receptacle is not exposed to conditions beyond its specified operating environment (e.g., excessive moisture, extreme temperatures) unless specifically rated for such conditions.
Troubleshooting
If you encounter issues with your Leviton 2460 Receptacle, refer to the table below:
