FAQs
The L820PW uses back wiring and supports #18–10 AWG conductors. Installation involves loosening the terminal screws, inserting conductors into the back of the body, and tightening to 14–16 lbf-in torque. Nickel-plated brass contacts provide reliable conductivity and corrosion resistance, ensuring a solid, field-friendly terminations for industrial wiring.
The plug is rated for 20A at 480V, in a two-pole, three-wire (NEMA L8-20) configuration. It features IP67 sealing, a locking mechanism to prevent accidental disconnection, and a torque rating of 14–16 lbf-in, making it suitable for demanding industrial circuits with rugged environments.
Yes. With IP67 sealing and compatibility with NEMA 4X/6P environments, the L820PW is designed for washdown areas, outdoor installations, and harsh facilities. The Santoprene seal and durable body materials help protect against moisture and particulates, supporting reliable operation in high-pressure cleaning or humid settings.
The L820PW is RoHS compliant and cULus listed, ensuring regulatory compliance and safer material usage. Its IP67 rating, along with NEMA L8-20 configuration, reinforces suitability for hazardous or moisture-prone environments, giving engineers confidence in safety, performance, and traceability for industrial applications.
Expect reduced downtime due to robust moisture protection, corrosion resistance, and a secure locking mechanism that prevents accidental disconnections. Back wiring simplifies field installation, saving labor time. Combined with a durable nickel-plated contact system and Santoprene seals, this plug lowers ongoing maintenance costs and extends service life in rugged, high-use lines.
