Eaton AHCL820P Locking Plug - cULus Listed, 480 V
Part Number: AHCL820P
Quick Summary
Eaton Arrow Hart color coded locking plug provides secure, color-coded electrical connections for industrial machinery. This device helps prevent miswiring and accidental disconnections in high-demand automation lines. Designers and maintenance teams often wrestle with cord mouting and incorrect wiring that causes downtime; a locking plug reduces that risk by ensuring a true mechanical lock and consistent polarity. With cULus listing, RoHS compliance, and NAFTA compatibility, the AHCL820P meets stringent safety and regulatory requirements while supporting efficient procurement. The nylon Ultra grip body and back-wire design offer durable installation in harsh factory environments, and its L8-20/NEMA configuration aligns with common 480V industrial circuits, delivering reliability and measurable uptime improvements. Additional benefits come from color coding and robust torque specifications that simplify field service.

Eaton Specification Sheet - AHCL820P
Color coded locking plug design improves safety by clearly indicating voltage and polarity, reducing miswiring events and downtime in 480 V industrial circuits. This directly supports faster, safer maintenance and changeovers, while aligning with long-term reliability expectations for automation lines and assembly cells. The L8-20 two-pole, three-wire configuration combined with a 20A rating provides a robust solution for demanding equipment using 480 V power, enabling predictable current handling and reduced nuisance trips during startup. Its back wiring method and 0.38-1 in cord diameter compatibility simplify installation for electricians and contractors, cutting field labor time and errors. Nylon Ultra grip housing enhances durability against vibration and harsh factory conditions, contributing to lower part replacement costs and extended service life. The operating range of -40 to 60 °C supports outdoor or unconditioned environments common in manufacturing floors. RoHS compliance and NAFTA participation streamline sourcing and regulatory adherence. Torque values of 14-16 lbf-inch for smaller AWG and 20 lbf-inch for #8 AWG provide clear, repeatable installation guidance, reducing maintenance variability. Color coding further supports quick identification during wiring, panel assembly, and inventory management, while the back-wired configuration minimizes the need for wire ferrules and simplifies rework when wiring changes are required.

FAQs
AHCL820P is a two-pole, three-wire locking plug configured for L8-20 (NEMA) outlets, rated at 20A and 480V. It uses a back-wire termination method compatible with #14-8 AWG conductors and a cord diameter range of 0.38-1 in. The design supports secure, code-compliant mating with standard L8-20 receptacles in industrial installations.
Torque guidance ensures a reliable, vibration-resistant connection. The product specifies 14-16 lbf-in for #10-14 AWG conductors and 20 lbf-in for #8 AWG. Following these torque values helps prevent loosening from startup transients, reduces connection resistance, and minimizes downtime due to loose or unreliable terminations on 480 V circuits.
Yes. The AHCL820P uses a nylon body with Ultra grip design, offering durability in environments with vibration and temperature variation. Its operating range of -40 to 60 °C supports cold factory floors and warm production lines, while the locking mechanism reduces accidental disconnections during machine cycles, enhancing uptime for automation equipment.
AHCL820P carries cULus Listed NOM certifications and RoHS compliance with NAFTA compatibility. These certifications help ensure regulatory compliance, safer electrical installations, and easier procurement across North American projects, while supporting end-user confidence in product safety and environmental responsibility during audits.
The locking design reduces inadvertent disconnections, cutting downtime and rework. Its durable nylon housing and back-wiring capability simplify field servicing and replacements, lowering maintenance labor costs. Over time, the reliable 480 V, 20 A performance and color coding help reduce wiring errors, contributing to faster maintenance cycles and a favorable return on investment.
