FAQs
AHCL820C supports back-wiring with a 3-wire, two-pole L8-20 configuration and is rated for #14-8 AWG conductors. It delivers a 20A, 480V capacity, and a cord diameter range of 0.38-1 inches, enabling straightforward field terminations. This compatibility reduces the need for rewiring adapters, speeds panel assembly, and simplifies maintenance when replacing older connectors. Ensure correct wire sizing and torque per the spec sheet to maintain safe, code-compliant connections.
Torqueing varies by conductor size: 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG. Use a calibrated torque tool and tighten each terminal to the specified value to prevent looseness or overheating. With the back-wiring method and nylon Ultra Grip housing, you’ll experience consistent torque retention and lower termination stress, which translates to longer connector life and reduced maintenance intervals in motor and conveyor installations.
Yes. The AHCL820C is designed for industrial applications, including motor control panels and conveyors, with a -40 to 60 °C operating range and a robust nylon housing featuring Ultra Grip. The color-coded terminals help prevent cross-wiring during routine service, while the back-wiring capability supports quick terminations in tight spaces. Its compliance slate (RoHS NAFTA, cULus NOM) also supports deployment in regulated manufacturing facilities.
AHCL820C carries RoHS compliance, NAFTA conformity, and cULus Listed NOM certifications, signaling adherence to environmental and safety standards, cross-border trade requirements, and electrical safety. These certifications accelerate procurement approvals, simplify supplier qualification for OEMs, and support regulatory audits in North American and international markets.
Using AHCL820C provides measurable ROI through faster installation, reduced wiring errors thanks to color coding, and improved regulatory compliance with RoHS, NAFTA, and cULus NOM. The nylon Ultra Grip design resists wear in demanding environments, reducing replacement cycles and downtime. Its compatibility with #14-8 AWG, 20A at 480V, and L8-20 configurations supports scalable, reusable wiring schemes across multiple machines and lines.
