Installation Instructions
Follow these steps to properly wire your Leviton 2761 locking plug. Refer to the accompanying video for visual guidance.
Video: This video demonstrates the wiring process for Leviton Black and White Plugs and Connectors, including the steps for disassembling, preparing wires, making connections, and reassembling the device.
- Ensure Power is Off: Before beginning, verify that the power to the cable is completely off at the circuit breaker to prevent electrical shock.
- Identify Plug Configuration: The faceplate of the plug is stamped with the NEMA configuration, amperage, and voltage. Confirm these match your requirements.
- Disassemble the Plug:
- Using a Phillips head screwdriver, loosen the quick screws on the faceplate.
- Carefully remove the faceplate from the body housing.
- Loosen the two strain relief screws on the strain relief component.
- Prepare the Cable:
- Feed the cable through the loosened strain relief and then through the body housing.
- Strip the cord jacket according to the diagram on the instruction sheet (typically about 1.5 inches). Remove the stripped cord jacket to expose the individual wires.
- Prepare Individual Wires:
- Cut the green (ground) wire to approximately 1 inch in length.
- Strip approximately 5/8 inch of insulation from all remaining wires using wire strippers.
- Connect the Ground Wire:
- Insert the green (ground) wire into the wire well of the green (ground) terminal screw, located in the center of the device.
- Tighten the terminal screw securely with a Phillips head screwdriver.
- Connect the Neutral Wire:
- Insert the white (neutral) wire into the wire well of the silver terminal screw.
- Tighten the terminal screw securely.
- Connect Remaining Wires:
- Insert the remaining three wires into the wire wells of the brass terminals.
- Tighten each brass terminal screw securely.
- Reassemble the Plug:
- Slide the faceplate back into the body housing, ensuring the channel guide on the body housing aligns perfectly with the faceplate.
- Tighten the quick screws on the faceplate with a Phillips head screwdriver.
- Secure Strain Relief:
- Tighten both screws on the strain relief to secure the cable.
- Note: If your wire is larger than the groove on the strain relief, a section of the strain relief can be removed to accommodate larger wire sizes.
Operation
Once properly wired and assembled, the Leviton 2761 locking plug is ready for use. Insert the plug into a compatible NEMA L19-30R receptacle and twist to lock it into place, ensuring a secure electrical connection. To disconnect, twist in the opposite direction and pull.
Maintenance
Regularly inspect the plug for any signs of wear, damage, or loose connections. Ensure the cable jacket and strain relief are intact to prevent wire exposure. Clean the plug exterior with a dry cloth as needed. Do not use abrasive cleaners or solvents. If any damage is observed, discontinue use and replace the plug.
Troubleshooting
- No Power: Check the circuit breaker to ensure power is on. Verify all wire connections within the plug are secure and correctly terminated.
- Loose Connection: If the plug feels loose in the receptacle, inspect the plug blades for damage or wear. Ensure the locking mechanism is fully engaged.
- Overheating: If the plug or cable feels hot during operation, immediately disconnect power. This could indicate an overload, a short circuit, or a loose connection. Consult a qualified electrician.
