Back wiring and a four-wire configuration streamline field terminations, reducing installation time on crowded control panels and in fixed installations. This translates to lower labor costs and fewer wiring mistakes in high-volume manufacturing and packaging lines where uptime matters. The L1620RW is designed for 3Ø 480V power distribution in industrial facilities, delivering reliable connections for motors, drives, and heavy-duty loads. The locking receptacle design minimizes accidental disconnections in vibration-prone equipment such as conveyors, crushers, and mobile tools. This results in fewer outages, safer startup sequences, and improved mean time between failures (MTBF). The device supports back wiring with #14-8 AWG allowed, including torque specs for #10-14 AWG and #8 AWG to ensure proper clamping. Rugged housing materials—glass-filled nylon body and thermoplastic face—resist impact, moisture, and chemical exposure common in plant floors and outdoor installations. Nickel-plated bronze contacts maintain low contact resistance over temperature swings, delivering consistent performance and reduced energy loss. IP66 environmental resistance along with NEMA 3R, 4X, 4, 3, and 12 ratings provides protection against water, dust, and washdowns while maintaining electrical integrity in demanding applications. RoHS compliance and cULus listing enable global deployment across facilities and supply chains, while the color coding (yellow) enhances visibility during installation and testing. The combination of compact form, back-wiring, and rugged construction supports fast retrofits and scalable integration into existing industrial power distribution networks.

FAQs
The L1620RW supports back-wiring with allowable wire sizes of #14-8 AWG. For field terminations, torque requirements are 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG. Grounding is included in the four-wire configuration, and the device is compatible with 3Ø 480V systems, enabling quick and secure panel connections in demanding environments.
The receptacle delivers 20A at 3Ø 480V, with NEMA configuration L16-20 and a three-pole, four-wire arrangement. Its locking design provides a secure connection under vibration, while the IP66 rating and multiple NEMA protections ensure reliable operation in exposure to dust and water in industrial settings.
Yes. The L1620RW features IP66 environmental resistance and is compatible with NEMA 3R, 4X, 4, 3, and 12 protection schemes, making it suitable for outdoor installations and washdown zones. Its yellow, high-visibility housing, locking mechanism, and rugged materials further enhance reliability in harsh, moisture-prone facilities.
The L1620RW is RoHS compliant and cULus listed NOM, supporting global deployment and regulatory compliance. These certifications help customers meet environmental and electrical safety standards across regional markets, reducing risk in cross-border projects and supplier audits.
Locking connections reduce the risk of unintended unplugging, improving uptime and MTBF in dynamic industrial settings. Durability comes from a glass-filled nylon body, thermoplastic construction, and nickel-plated bronze contacts, delivering long service life with lower maintenance costs. Back wiring also simplifies field wiring, shortening installation time and lowering labor expenses during retrofits or upgrades.
