Built from impact-resistant nylon with a self-grounding design, this plug is engineered for demanding three-phase power connections in commercial and industrial environments. It accepts cord diameters from 0.35 inches to 1.15 inches, providing compatibility with a wide range of heavy-duty flexible cordsets. Licensed electricians and industrial maintenance technicians are the primary installers for this type of connector.\u003c\/p\u003e\n\u003cp\u003eThis locking plug is suited for industrial facilities, manufacturing floors, data centers, and commercial construction sites where three-phase 277\/480-volt power distribution is required. The L22-20P configuration is a standard NEMA locking pattern used in high-voltage branch circuit applications. Its IP20 ingress protection rating makes it appropriate for indoor dry-location installations where accidental finger contact with live parts must be prevented.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eL22-20P NEMA locking configuration for secure 277\/480-volt three-phase connections\u003c\/li\u003e\n  \u003cli\u003e20-amp amperage rating across 4 poles and 5 wires\u003c\/li\u003e\n  \u003cli\u003eImpact-resistant nylon construction for durability in industrial environments\u003c\/li\u003e\n  \u003cli\u003eSelf-grounding design simplifies installation and ensures reliable ground continuity\u003c\/li\u003e\n  \u003cli\u003eAccepts cord diameters from 0.35 inches to 1.15 inches\u003c\/li\u003e\n  \u003cli\u003eIP20 ingress protection rating for indoor dry-location use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with L22-20R locking receptacles and inlets in industrial 277\/480-volt three-phase wiring systems.
