Locking receptacle
The watertight construction protects connections from moisture, dust, and splash exposure, reducing corrosion and unplanned downtime while ensuring consistent current delivery for 20 A loads in demanding facilities. This design translates into measurable uptime gains and safer maintenance routines in motor control centers and outdoor installations. The locking receptacle configuration (L8-20) with two-pole, three-wire grounding provides a secure mating connection, preventing accidental disconnections during vibration or heavy load cycles, which lowers maintenance calls and equipment damage. Back wiring supports fast, clean terminations with wire sizes from #14 to #8 AWG, streamlining field installs and reducing switchgear footprint. The rugged thermoplastic body and glass-filled nylon face offer chemical resistance and long service life in harsh environments, while the nickel-plated bronze contacts enhance conductivity and longevity. Color-coding in yellow improves visibility during panel updates and service. The design also supports compatibility with standard industrial enclosures and straightforward installation practices, aiding procurement with clear specifications and consistent performance expectations.

FAQs
Install using back wiring with #14-8 AWG conductors. Follow torque specs: 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG. The unit measures 6.75 in length, 4 in height, and 4.25 in width, fitting standard enclosures. Use the yellow face for high visibility and ensure proper strain relief to maintain a watertight seal.
Yes. The L820RW is designed for wet environments with IP66 and NEMA 4/4X (also NEMA 3 and 12) environmental protection. It is RoHS compliant and cULus listed, meeting safety and environmental standards. This combination supports compliant installation in food processing, water treatment, and outdoor automation equipment while reducing regulatory risk.
The receptacle provides a 20 A, 480 V rating in an L8-20, two-pole, three-wire configuration. It uses back wiring for #14-8 AWG conductors and features a locking type receptacle for secure connections. This enables reliable power delivery to industrial motors, pumps, and conveyors while maintaining a compact footprint.
Locking ensures the plug remains mated even amid vibration, equipment movement, or accidental tugs, significantly reducing unscheduled outages. The two-pole, three-wire grounding design supports safe power transmission, while the rugged thermoplastic body and nickel-plated bronze contacts preserve performance over time. In high-cycle applications, this translates to fewer maintenance calls and safer operation.
With a length of 6.75 in, width of 4.25 in, and height of 4 in, the unit fits standard industrial enclosures. The body is glass-filled nylon and thermoplastic, offering chemical resistance and durability in tough environments. The nickel-plated bronze contacts provide reliable conductivity, and the yellow color improves visibility during panel wiring and service.
