FAQs
Yes. The L720RWBK is designed for back wiring with #14-8 AWG conductors. It supports straightforward termination in confined spaces, aided by its compact footprint and clearly labeled wiring path. For best results, follow the torque guidelines (14-16 lbf-in for #10-14 AWG; 20 lbf-in for #8 AWG) to ensure a reliable, vibration-tolerant connection.
This receptacle carries IP66 environmental protection and NEMA compatibility (12, 4, 4X, 3R, 3). It is RoHS compliant and cULus listed, which supports safety, reliability, and regulatory alignment in industrial facilities and outdoor installations.
Absolutely. The unit is rated for 277 V and 20 A in a two-pole, three-wire configuration (L7-20), making it compatible with common industrial motors, pumps, and portable equipment that require locking receptacles for secure connections in dynamic work environments.
Plan periodic inspection of the locking mechanism, seals, and contacts. Thanks to nickel-plated bronze contacts and a thermoplastic body, the receptacle offers longevity and corrosion resistance. If ingress protection is compromised or wiring shows signs of wear, replace the receptacle to maintain uptime and safety.
By combining watertight IP66 protection, rugged materials, and back-wiring efficiency, the L720RWBK lowers maintenance time, reduces field repair costs, and minimizes downtime. Compatibility with RoHS and robust NEMA ratings further enhance reliability and regulatory compliance, delivering a favorable long-term total cost of ownership for industrial deployments.
