Feature → Business Impact → Application: The L1420RWBK uses a thermoplastic body with glass-filled nylon faces to resist impact and chemical exposure, increasing panel life in harsh environments and reducing replacement costs in manufacturing lines. This translates to higher uptime in automotive, food & beverage, or packaging facilities where frequent washdowns occur. Feature → Business Impact → Application: Nickel-plated bronze contacts provide superior corrosion resistance and low contact resistance, improving connection reliability under continuous vibration and heavy loads typical of material handling and processing lines. This supports safer operation and minimizes arc faults in high-duty-duty cycles. Feature → Business Impact → Application: Back wiring with #14-8 AWG capability simplifies field terminations, cutting installation time and enabling rapid panel upgrades in large electrical rooms or retrofit projects. Feature → Business Impact → Application: Locking receptacle design reduces accidental disconnections in conveyors and outdoor equipment, delivering consistent power delivery and reducing maintenance dispatches in harsh environments. Feature → Business Impact → Application: Environmental protection including IP66/NEMA 12, 3R, 4 and 4X ensures resistance to water, dust, and corrosion, supporting outdoor installations and washdown zones without additional enclosures. This aligns with compliance objectives for facilities requiring robust weatherproof electrical components. Feature → Business Impact → Application: The device is rated for 125/250 V and 20 A, enabling flexible configuration for industrial machinery that needs dual-voltage capability while maintaining a compact footprint in control panels and motor starter assemblies. The overall result is improved reliability, safer operation, and a lower total cost of ownership for electrical distribution systems in manufacturing, logistics, and process industries.

FAQs
Yes. The L1420RWBK supports back wiring with #14-8 AWG conductors, making field terminations faster and neater. Its design accommodates common panel layouts, reducing the need for rework and enabling quicker retrofit or new-install projects in manufacturing floors and control cabinets.
The receptacle is rated for 20A and 125/250V with an L14-20 configuration, three poles and four wires (including grounding). It carries NOM and cULus listings and provides weatherproof, watertight protection (IP66/NEMA 12/3R/4/4X), supporting reliable operation in demanding industrial environments.
Ideal for outdoor, washdown, and dusty environments, including manufacturing floors, process plants, and outdoor equipment enclosures. Its watertight design, multiple NEMA/IP protections, and robust materials make it suitable for harsh industrial applications requiring dependable, sealed power connections.
The L1420RWBK is NOM and cULus Listed, confirming compliance with relevant North American electrical safety standards. Its IP66 and NEMA 12/3R/4/4X protections further ensure suitability for moisture, dust, and corrosion-prone environments in industrial facilities.
Locking connections prevent accidental disconnections, reducing downtime and rework. Nickel-plated bronze contacts withstand corrosion, while a thermoplastic, glass-filled body resists wear. Together with high ingress protection, this lowers maintenance frequency and extends service life in harsh duty cycles.
