Leviton Telcom 29W81-B Locking Connector L21-30R

Product Description

The LEVITON TELCOM 29W81-B is a locking electrical connector rated for 4-pole, 5-wire, 3-phase wiring in the NEMA L21-30R configuration. This body and grounding connector is designed for secure, twist-lock engagement, preventing accidental disconnection under load. The L21-30R designation indicates a 30-amp, 120/208-volt, 3-phase Y configuration. Electricians use this connector in commercial and industrial power distribution applications where a reliable, code-compliant connection is required. The twist-lock mechanism provides a positive retention system suited for environments where vibration or movement could otherwise loosen a standard straight-blade connection.

This connector is suited for use in commercial buildings, light industrial facilities, and portable power distribution systems where 3-phase, 5-wire service is present. Typical applications include generator hookups, power distribution units, and temporary or permanent equipment connections requiring a secure locking interface. It is sold as a single unit and is intended for installation by a licensed electrician in accordance with applicable electrical codes.
