FAQs
The L2220CWBK supports back wiring for #18-10 AWG conductors. Strip the insulation per conductor size, insert the conductors into the back-wiring terminals, and tighten to the specified torque. Use 14-16 lbf-in for #10-14 AWG or 20 lbf-in for #8 AWG to ensure a secure connection. Verify polarity and grounding before closure.
This connector is rated at 20A and supports 277/480V in a four-pole, five-wire configuration (L22-20). It is intended for three-phase power distribution in industrial equipment and control panels, with grounding included for safe operation in demanding environments.
Yes. The connector offers IP67 protection and is compatible with NEMA 6, 6P, and 4X environments. This watertight design protects against dust, water immersion, and washdown conditions, helping maintain performance and reducing maintenance in outdoor and wet-process installations.
The L2220CWBK is RoHS compliant and cULus Listed, ensuring regulatory alignment and safety for North American applications. Its IP67 rating and NEMA compatibility further support compliance in industrial automation and hazardous-duty environments.
Use the back-wiring method with the correct wire gauge (#18-10 AWG) and apply the specified torque to ensure a secure, vibration-resistant connection. The nylon body, Santoprene seal, and nickel-plated brass contacts promote durability and corrosion resistance, reducing downtime and extending service life in automation and control-panel applications.
