Industrial Locking Connector

The Legrand L520CGCM is a NEMA L5-20R locking connector rated for 20 A at 125 V AC. It accepts three conductors in a straight orientation and features ground continuity monitoring for added safety on job sites. The nylon housing resists chemicals and impacts.

Three-Phase Service Installers

This connector suits electricians wiring 20 A, 125 V locking receptacles on three-phase distribution where ground monitoring is required. It will not serve applications needing a shrouded body, an IP-rated seal, or a higher current rating than 20 A.

NEMA L5-20R Configuration

The single specification that decides fit is the NEMA L5-20R configuration, which defines a 2-pole, 3-wire, 125 V AC locking interface. Cable diameter must fall between .385 in and .69 in for proper strain relief.

How can I verify the ground continuity monitoring is active once installed?
