Eaton L2020RWBK Watertight locking receptacle - IP66
Part Number: L2020RWBK
Quick Summary
Eaton L2020RWBK watertight locking receptacle delivers reliable power connections for industrial equipment in harsh environments. Moisture, dust, and vibration spike downtime and safety risks if connectors aren’t sealed and locked. This model carries cULus Listed NOM certifications and rugged IP66/NEMA 4X protection to meet harsh-site requirements. In addition to back wiring for quick field installs, it supports #14–8 AWG conductors and a four-pole, non-grounding layout. These features translate to reduced commissioning time, safer connections, and lower maintenance costs in industrial facilities. Its thermoplastic housing with glass-filled nylon face ensures chemical resistance, impact protection, and a durable seal. Additionally, the 347/600V rating supports heavy three-phase distribution in industrial plants.

FAQs
L2020RWBK supports 347/600V three-phase systems and back wiring for #14–8 AWG conductors. To install, prepare the panel or enclosure, strip conductors to the correct length, insert into the back-wiring terminals, secure with proper torque, and verify the locking mechanism engages. This approach minimizes field wiring errors and accelerates commissioning in industrial cabinets.
Key specs include 20A amperage, NEMA configuration L20-20, four poles with four wires (non-grounding), and a 3ØY 347/600 V rating. The device is designed for industrial environments, with back wiring support for #14–8 AWG wires and a locking receptacle type to prevent accidental disconnection during operation.
Yes. The receptacle carries IP66 and NEMA 4X environmental ratings, along with NEMA 4, 3R, 3, and 12 protections, making it suitable for outdoor installations and washdown areas. Its watertight design, durable thermoplastic housing, and corrosion-resistant contacts ensure reliable performance in harsh industrial settings.
The L2020RWBK is cULus Listed and NOM certified, reflecting compliance with North American electrical safety standards. The IP66 and NEMA 4X ratings further reinforce suitability for demanding environments, helping facilities meet regulatory and safety requirements during audits and inspections.
Upgrading to a watertight locking receptacle like L2020RWBK reduces downtime from ingress-related faults and disconnections, lowers maintenance costs due to robust sealing and durable materials, and accelerates installation with back wiring. In practice, facilities see improved process uptime, safer connections, and simpler compliance reporting for industrial power connections.
