FAQs
Start by inspecting the back-wiring terminals and preparing #18-10 AWG conductors. Strip to the correct length, insert into the back-wiring terminals, and tighten to the specified torque (14-16 lbf-in). Ensure the Santoprene seal and nylon housing are properly seated to maintain IP67 integrity. Verify the L6-20 configuration and perform a continuity check before energizing the circuit.
Ideal for outdoor or washdown areas, the L620PWBK supports industrial equipment connections requiring IP67 protection and 20A at 250V. It is suitable for panels, motors, pumps, and other equipment that demand a rugged, watertight connection with back wiring for efficient field terminations.
The plug is RoHS compliant and cULus Listed NOM, with IP67 protection and NEMA compatibility for 4/6/4X environments. It also supports NEMA L6-20 configurations, making it suitable for industrial power distribution in harsh conditions while meeting safety and regulatory requirements.
Yes, the L620PWBK uses the L6-20 configuration and accepts #18-10 AWG conductors with back wiring. The design includes a 14-16 lbf-in torque rating for reliable retention, ensuring a secure connection in vibration-prone applications and simplifying replacement in service environments.
The watertight design minimizes ingress and corrosion, reducing downtime and maintenance costs in washdown or outdoor settings. Regulatory compliance (RoHS, cULus NOM) streamlines audits, while back wiring speeds installation. Combined with a durable nylon/santoprene construction and nickel-plated contacts, the plug extends service life, lowers replacement frequency, and improves overall equipment availability.
