Locking mechanism and color coding reduce misplugging and improve safety in busy panels. By ensuring a secure lock and clear identification, maintenance crews can connect equipment quickly and with confidence. This is ideal for motors, conveyors, and other industrial loads that demand reliable startup in harsh environments. Back and side wiring compatibility simplifies field installations. The 3 wire three conductor arrangement supports flexible mounting and wiring options, reducing panel modification time and enabling faster retrofits in existing distribution networks. Rugged construction uses glass filled nylon withstanding -40 to 70 C. Coupled with a 20 lbf-in torque rating and Ultra grip design, the receptacle maintains a solid connection through vibration and temperature swings common in industrial plants. Color coded voltage coding aligns with code requirements and reduces human error across shifts. This feature plus UL Listed and CSA certified compliance ensures safer installations and easier audits. L7-20 277V 20A rating ensures compatibility with typical industrial motors and equipment; RoHS compliance reduces hazardous substances; The unit supports reliable operation in demanding environments and simplifies maintenance planning for facilities with mixed voltage deployments.

FAQs
Ensure panel is rated for 277V and meets L7-20 compatibility. Use back and side wiring with #14-8 AWG conductors, tighten to the 20 lbf-in torque specification, and verify a secure lock with the color coded terminals. Follow all local codes and NEC guidance when mounting and routing cables, and confirm UL CSA approvals are reflected in the panel schedule.
The AHCL720R is a 20A, 277V locking receptacle with a two pole three wire configuration. It uses back and side wiring, accepts #14-8 AWG wires, has a torque rating of 20 lbf-in, and a NEMA configuration of L7-20. It operates from -40 to 70 C and features voltage color coding for quick identification.
Yes. The device uses glass filled nylon with a rugged Ultra grip design and is rated for -40 to 70 C operation. Its construction resists vibration and temperature swings typical in manufacturing facilities, while the locking mechanism minimizes accidental disconnections during high duty cycles.
The AHCL720R carries UL Listed and CSA Certified marks, is RoHS compliant, and aligns with NOM Federal Specification Classification 6233 01. These certifications support compliance audits, safety assurances, and compatibility with North American electrical standards.
Color coding reduces mis-wiring and speeds testing and startup, while the locking mechanism prevents accidental disconnects during operation. Together they lower downtime, improve safety audits, and shorten maintenance cycles, delivering measurable ROI through reduced replacement events and faster service repairs in busy industrial environments.
