Leviton 2311-PLC Locking Plug L5-20P 20A 125V

Product Description

The LEVITON 2311-PLC is an industrial-grade locking plug rated at 20 amps and 125 volts, configured to the NEMA L5-20P standard. It features a 2-pole, 3-wire self-grounding construction built for demanding job-site and facility power connections. The body is molded from nylon for durability and resistance to impact. Single-phase design suits portable equipment, generators, and temporary power distribution panels where a secure, twist-lock connection is required. Licensed electricians and facilities maintenance professionals are the primary installers.

This plug is suited for industrial and commercial applications where a reliable locking power connection prevents accidental disconnection under load. Typical use cases include portable generators, temporary construction power, industrial machinery, and stage or event power distribution. The L5-20P configuration is a common choice for 20-amp, 125-volt single-phase circuits in facilities that require NEMA locking-type connectors throughout their power distribution infrastructure.
