20 A Three-Phase Locking Connector

This 20 A locking connector uses a straight NEMA L21-20R configuration with four poles and five wires for 120/208 V AC three-phase power. The nylon housing in black and white provides chemical and impact resistance. Brass contacts and screw terminals accept cables up to 1.15 in. diameter. It is rated IP20 and ships without a cap or cover.

Screw-Terminal Installation Notes

Installation requires stripping conductors and securing them under the screw terminals, a straightforward process for qualified electricians. Common issues include loose terminal screws leading to overheating, incorrect phase wiring on the five-wire layout, and exceeding the 1.15 in. cable diameter limit which prevents proper gland sealing. The straight orientation demands adequate clearance behind the panel.

Pre-Order Compatibility Check

Verify that the supply is a three-phase 120/208 V AC system matching the NEMA L21-20R pinout. Confirm the existing cable outer diameter does not exceed 1.15 in. and that the jacket material suits the nylon housing's chemical resistance. Ensure the mounting location meets IP20 environmental requirements and provides space for the straight-back wiring style.
