Leviton 4720-PLC Locking Plug L5-15P 125V 15A

Product Description

The LEVITON 4720-PLC is an industrial-grade locking plug rated for 125 volts and 15 amps, configured to the NEMA L5-15P standard. It features a 2-pole, 3-wire self-grounding design built from impact-resistant nylon, making it a reliable termination point for portable power cords in demanding electrical environments. The plug accepts cord diameters from 0.24 inches to 0.70 inches, covering a wide range of standard flexible cord sizes. Licensed electricians and industrial maintenance technicians install this plug when a twist-lock connection is required to prevent accidental disconnection under load.

The 4720-PLC suits single-phase applications in industrial facilities, commercial buildings, and job-site environments where NEMA L5-15P locking connectors are specified. It is commonly used to terminate extension cords, portable equipment power leads, and temporary power runs where a secure, vibration-resistant connection is required. The two-color black and white housing aids polarity orientation during field termination.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit completely before disassembling or wiring the plug. Ensure cord strain relief is properly engaged and that wire terminations are tight before reassembling the plug body. Do not exceed the 15-amp or 125-volt ratings in service.
