Corrosion resistance protects terminations from moisture and chemicals, extending service life and lowering maintenance costs. In practice, you’ll experience fewer field failures and longer intervals between replacements in outdoor panels, washdown zones, and coastal facilities. The locking mechanism with a safety grip provides positive retention amid vibration, reducing the risk of accidental disconnections and electrical faults during high-load cycles in motors, compressors, and HVAC equipment. Back wiring delivers clean terminations and faster installs, simplifying field wiring while accommodating a wide range of cables. The nylon body and nickel-plated brass contacts offer durability and low contact resistance, ensuring reliable performance under temperature swings and mechanical wear. With a three-pole, four-wire L14-20 configuration, this connector fits common industrial power layouts and minimizes panel clutter. Design features such as the yellow color enhance visibility for quick identification in busy environments. Engineered for #14-8 AWG conductors and a cord diameter of 0.38–1 in, it integrates smoothly with Eaton’s locking devices ecosystem, reducing part variety and training needs. These attributes collectively deliver measurable ROI through reduced downtime, faster maintenance, and regulatory compliance across North American facilities.

FAQs
To install CRL1420C with back wiring, power must be off and conductors prepared to #14-8 AWG. Remove the terminal block cover, insert conductors into the back-wiring terminals, and tighten to the specified torque (14–16 lbf-in). Confirm correct polarity and secure the connector so the locking mechanism engages fully, ensuring vibration resistance and a safe, durable connection in panels and equipment.
CRL1420C is rated for 20A at 125/250V with an L14-20 NEMA configuration. It is a three-pole, four-wire locking connector designed for industrial power distribution, motors, and generators. This configuration supports versatile three-phase and single-phase applications while maintaining secure, code-compliant terminations in demanding environments.
Yes. The connector’s corrosion-resistant nylon body and nickel-plated brass contacts are built for durability in harsh environments. Its back-wiring capability and robust locking mechanism minimize vibration-related disconnections. With a wide cord diameter range (0.38–1 in) and wire size compatibility (#14-8 AWG), it supports field wiring needs common in motor control centers, generator sets, and heavy machinery.
CRL1420C carries cULus Listed, NOM certified, and CSA certified markings. These certifications verify safety, performance, and regulatory compliance for North American installations. They help ensure the connector meets recognized standards for electrical assemblies used in industrial settings, reducing compliance risk and aiding supplier qualification and inspection processes.
Adopting CRL1420C yields ROI through reduced downtime, fewer maintenance cycles, and longer service life due to corrosion resistance and robust construction. The locking design minimizes disconnections during vibration, while back wiring speeds installation and simplifies future servicing. Over time, these factors translate into lower labor costs, improved equipment uptime, and safer, compliant power connections.
