Product Overview
The Leviton 515PR is a 2-pole, 3-wire grounding plug designed to meet NEMA 5-15P standards. It features a durable elastomeric rubber husk for protection and a two-piece strain relief cord grip clamp to secure the cable and prevent stress on the wire terminals. The plug utilizes triple drive head screws (compatible with Slotted, Philips, and Robertson screwdrivers) for easy and secure wiring. The husk and module are keyed for correct alignment during assembly, and the NEMA rating is molded into the front for clear identification.

Setup and Installation
This section outlines the steps for wiring the Leviton 515PR plug to an electrical cord. Ensure power is disconnected before proceeding.
Tools Required:
- Wire strippers
- Screwdriver (Slotted, Philips, or Robertson compatible with 3/16-inch screws)
- Utility knife (optional, for outer jacket)
Wiring Steps:
- Prepare the Cord: Carefully cut the end of your electrical cord to the desired length. Using a utility knife or wire strippers, remove approximately 1.5 to 2 inches of the outer jacket of the cord, exposing the insulated inner wires (typically black, white, and green/bare copper). Be careful not to nick the insulation of the inner wires.
- Strip Inner Wires: Strip approximately 1/2 inch of insulation from the end of each inner wire (black, white, green/bare copper). Twist the strands of each wire tightly to prevent fraying.
- Disassemble the Plug: Loosen the two screws on the side of the rubber husk and separate the husk from the plug module.
- Route the Cord: Slide the rubber husk onto the prepared electrical cord, ensuring the narrow end of the husk faces the stripped wires.
- Connect Wires to Terminals: The plug module has three screw terminals. Connect the wires as follows:
- Green Wire: Connect to the Green screw terminal (ground).
- White Wire: Connect to the Silver screw terminal (neutral).
- Black Wire: Connect to the Brass screw terminal (hot/live).
- Secure Strain Relief: Position the cord within the two-piece strain relief clamp inside the plug module. Tighten the screws on the strain relief to firmly grip the cord, preventing it from being pulled out or stressing the wire connections. The strain relief is designed to center the cord for a neat installation.
- Reassemble the Plug: Align the keyed features of the plug module with the rubber husk. Carefully push the husk over the module until it is fully seated. Tighten the two screws on the side of the husk to secure the assembly.
- Test: Once assembled, visually inspect all connections. Restore power and test the wired cord with a suitable appliance.
This plug is compatible with 18-3, 16-3, 14-3, and 12-3 AWG cord sizes, accommodating diameters from 0.245 to 0.655 inches.
Operating Instructions
Once properly installed and wired to an electrical cord, the Leviton 515PR plug operates like any standard NEMA 5-15P plug. Insert the plug firmly into a compatible 125 Volt, 15 Amp NEMA 5-15R receptacle. Ensure the appliance connected to the cord is within the plug's electrical ratings.
Maintenance
Regular inspection and proper care will ensure the longevity and safe operation of your Leviton 515PR plug.
- Visual Inspection: Periodically inspect the plug and the connected cord for any signs of damage, such as cracks, cuts, fraying, or discoloration. Check for loose connections or exposed wires.
- Cleaning: If necessary, clean the exterior of the plug with a dry cloth. Do not use liquid cleaners or immerse the plug in water.
- Storage: Store cords equipped with this plug in a dry, safe place when not in use, away from extreme temperatures or direct sunlight.
- Repair/Replacement: If any damage is found, discontinue use immediately. Do not attempt to repair a damaged plug. Replace it with a new, properly wired plug.
Troubleshooting
