IP67 watertight protection minimizes water and dust ingress, lowering corrosion risk and unplanned maintenance. This translates to fewer service interruptions in outdoor or washdown environments, saving downtime and maintenance costs for conveyors, pumps, and processing lines. Three-pole, four-wire configuration (NEMA L15-20) with back wiring for #18-10 AWG simplifies field wiring, accelerating installation and reducing labor time on a busy plant floor. The torque rating of 14-16 lbf-in paired with nickel-plated brass contacts ensures consistent, reliable terminations under vibration and load, improving electrical reliability and reducing contact-resistance concerns. Santoprene sealing and a nylon body deliver durable moisture resistance without adding excessive weight, supporting easy handling in tight panels or elevated installations. RoHS compliance alongside UL Listed, cULus Listed, NOM, and CSA certifications helps with procurement and regulatory alignment while the yellow body enhances visibility for safe, quick identification in busy environments. Overall, these design choices enable longer service intervals, easier maintenance, and safer, compliant power distribution in industrial settings.

FAQs
Begin by wiring the conductors per the device’s back-wire method, ensuring the wires are within the #18-10 AWG range. Insert each conductor into its designated terminal and tighten to the specified torque range of 14-16 lbf-in. Verify insulation integrity and secure the connector housing to prevent movement. Finally, test the connection for proper conductivity and observe IP67 sealing after reassembly to confirm watertight performance in the intended environment.
L1520PW is a 20A, 250V locking plug configured as a 3-pole, four-wire assembly (NEMA L15-20). It supports back wiring with #18-10 AWG conductors and provides IP67 ingress protection. The device uses nickel-plated brass contacts and a Santoprene seal inside a yellow nylon body, optimized for rugged industrial use with reliable torque and electrical performance.
Yes. The L1520PW is explicitly rated for NEMA L15-20 configurations and is designed for IP67 protection, making it suitable for outdoor and washdown environments. The locking mechanism, corrosion-resistant contacts, and robust materials further enhance suitability for rugged industrial applications where reliable locking power connections are required.
The L1520PW carries UL Listed, cULus Listed, NOM, CSA certified, and RoHS compliance. These certifications help ensure electrical safety, cross-border regulatory acceptance, and sustainability requirements. For procurement, these marks simplify supplier qualification and support compliance with industry standards in manufacturing, food processing, and harsh-duty environments.
The IP67 watertight design reduces ingress-related corrosion and failure, lowering maintenance frequency and downtime. Durable nickel-plated contacts, Santoprene seals, and a robust nylon body withstand vibration and environmental exposure, extending service life. While upfront cost may be higher than generic plugs, the reduced maintenance, fewer unplanned outages, and improved reliability contribute to a favorable total cost of ownership in demanding industrial settings.
