Locking receptacle
Watertight protection translates to fewer field failures in wet locations, improving uptime and safety for outdoor equipment. This locking receptacle secures connections under vibration and harsh conditions, reducing accidental disconnections and rework in high-motion industrial environments. Back wiring for #14-8 AWG conductors enables faster, error-resistant installations, lowering labor costs and field fatigue. Glass-filled nylon face and thermoplastic body deliver impact resistance and long-term durability in demanding plants, while nickel-plated bronze contacts ensure consistent conductivity and corrosion resistance in challenging environments. Compliance with IP66/NEMA 4X and Federal Specifications W-C375 helps satisfy procurement requirements for regulated projects and ensures market acceptance. Torque values—14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG—support reliable performance and predictable field servicing. This receptacle is compatible with standard L14-20 configurations and aligns with industry best practices for industrial power distribution in outdoor facilities.

FAQs
The L1420RW supports back-wiring and is rated for #14-8 AWG conductors, enabling straightforward field termination. This simplifies installation, reduces terminal footprint conflicts, and minimizes wiring errors, which speeds up commissioning and lowers onboarding costs for maintenance teams.
The L1420RW is NOM cULus Listed, UL Listed, and CSA certified, with Federal Specifications W-C375. These approvals indicate conformity with safety, performance, and regulatory standards across North American markets, easing procurement for regulated projects and ensuring supplier reliability.
Ideal for outdoor and wet-location applications, including outdoor equipment, weather-exposed motor controls, and service pedestals. Its IP66/NEMA 4X protection and locking design make it suitable for installations subject to moisture, dust, and vibration, reducing downtime and improving uptime in harsh environments.
For #10-14 AWG conductors, tighten to 14-16 lbf-in. For #8 AWG, use 20 lbf-in. Following these torque values ensures a secure connection, minimizes resistance changes over time, and reduces the risk of overheating or loosening under vibration.
Regular inspection for seals and locking integrity is recommended in outdoor or wash-down environments. Ensure the closure remains watertight, verify terminal integrity if rewiring, and replace any worn components promptly. The rugged construction and corrosion-resistant materials help extend service life when combined with periodic checks.
