Leviton Telcom 2520 Locking Receptacle L22-20R

Product Description

The LEVITON TELCOM 2520 is a locking receptacle designed for demanding electrical installations where secure, vibration-resistant connections are required. Built to the L22-20R configuration, it features a 4-pole, 5-wire layout that supports high-voltage three-phase circuits commonly found in industrial and commercial electrical systems. This receptacle is installed by licensed electricians working on panel feeds, equipment drops, and machinery connections where accidental disconnection cannot be tolerated. The twist-lock design ensures the mating plug stays engaged under load, reducing arc risk and unplanned downtime.

This receptacle is suited for commercial and industrial environments where three-phase power distribution is standard. Typical applications include motor-driven equipment, large HVAC systems, and process machinery that require a secure 20-amp twist-lock termination point. It is sold as an individual unit and is appropriate for new installation or replacement of a worn or damaged L22-20R outlet in an existing panel or enclosure.

Key Features

• L22-20R twist-lock configuration prevents accidental plug disengagement under load
• 4-pole, 5-wire design supports three-phase circuit wiring
• Single-unit packaging for direct replacement or new installation
• Hardware accessory grade construction suited for industrial service environments

Compatibility

Designed as an OEM-style replacement or new-install locking receptacle for commercial and industrial electrical systems requiring an L22-20R 4-pole 5-wire twist-lock outlet.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit and verify zero voltage with a meter before handling any wiring connections. Ensure the enclosure or box rating matches the receptacle body and that all conductors are properly torqued to terminal screws per the NEC. Do not install on a circuit that exceeds the receptacle amperage rating.
