FAQs
CRL620P supports back-wiring with a two-pole, three-wire L6-20 configuration rated at 20A and 250V. It accepts #14-8 AWG conductors within a 0.38–1 inch cord diameter, making it suitable for industrial equipment, control panels, and harsh environments where a secure locking connection is required.
Back wiring involves inserting conductors into the rear terminals and securing them to specification. The required torque range is 14–16 lbf-in to ensure a stable, low-resistance connection. Use the manufacturer’s guidance to avoid over-tightening while meeting the 20A/250V rating and two-pole, three-wire configuration.
Yes. The CRL620P uses a corrosion-resistant nylon body and nickel-plated brass contacts designed for longevity in challenging conditions. It carries UL Listed, cULus Listed, CSA certified, and NOM certifications, along with RoHS compliance and Federal Specifications classification W-C375 for regulated deployments.
Locking plugs prevent accidental disconnection in vibration-prone settings, improving system reliability. The design also features a safety grip, visible yellow body, and back-wiring compatibility that streamlines installation and reduces wiring errors. These traits translate into lower maintenance, safer operation, and predictable uptime for industrial systems.
The corrosion-resistant construction and robust electrical contacts minimize corrosion-related failures and contact resistance over time. Combined with easy installation and regulatory compliance, this reduces downtime, service calls, and field labor costs, delivering a favorable total cost of ownership for control panels and harsh-environment equipment.
