Color-coded locking inlet design delivers immediate safety and efficiency gains. The ANSI/IEC-compliant voltage color coding helps technicians verify correct connections at a glance, reducing mis-wiring during panel assembly or field service. The locking mechanism resists accidental pulls and vibration, which translates to fewer de-energized events and lower warranty costs. In practical terms, this configuration is ideal for industrial control panels, motor starters, and equipment cabinets where 480 V feeders must be clearly identified and securely retained. Nylon body and Ultra grip features combine lightweight handling with rugged durability. The nylon face and body resist impact, oils, and chemicals common in automated facilities, while the textured grip accelerates removal and replacement during maintenance windows. This material choice also contributes to noise reduction and ease of cleaning in dusty environments, which translates into longer service intervals and reduced downtime in high-cycle applications. Back-wiring and wiring method: Back, 3 wires, two-pole L8-20 configuration. Allowable wire size #14-8 AWG; torque ratings: 14-16 lbf-in for #10-14 AWG and 20 lbf-in for #8 AWG. This leads to faster, more repeatable terminations and consistent electrical performance across assemblies. Wide operating temperature range -40°C to 60°C enables reliable operation on shop floors, outdoors, or in refrigerated environments. The wide range reduces the need for multiple part numbers across geographic deployments, lowering procurement complexity and stocking costs. Regulatory and environmental compliance: RoHS compliant materials and cULus Listing NOM address common regulatory requirements in North America and Europe where applicable. The combination of these certifications supports supplier qualification packages and end-user audits, helping teams maintain compliance while accelerating project timelines.

FAQs

The AHCL820FI uses back-wiring for three conductors in a two-pole, L8-20 configuration. Use #14-8 AWG conductors within the rated torque range (14-16 lbf-in for #10-14 AWG; 20 lbf-in for #8 AWG). Ensure correct color-coded connections to hot, neutral, and ground per the color coding scheme. Tighten terminals to the specified torque, then secure the inlet in its flange and verify polarity before energizing the circuit.
Specifications include a 20A amperage rating and a 480 V voltage rating, back wiring, and a 3-wire configuration. It is a two-pole NEMA L8-20 arrangement with nylon face and body. Allowable wire size is #14-8 AWG, and operating temperature is -40 to 60 °C. The torque values ensure reliable terminations, and the color coded design supports correct installation and maintenance activities.
Yes. The AHCL820FI is specifically designed for color-coded locking connections in industrial panels, with back-wiring suitable for L8-20, 480 V systems. Its nylon housing and Ultra grip feature enhance durability and ease of installation. This makes it ideal for control panels, motor starters, and equipment cabinets operating in harsh environments and variable temperatures.
The AHCL820FI carries RoHS compliance and cULus Listed NOM certification, addressing environmental and safety requirements for North American installations. These certifications simplify supplier qualification, assist with regulatory audits, and reduce risk during customer approvals, helping projects stay on schedule while maintaining high safety and environmental standards.
The locking mechanism and color-coded design minimize miswiring and disconnections during machine start-ups, reducing unplanned downtime. Nylon housing offers durability against impact, oils, and dust, lowering replacement costs. The back-wired 3-wire configuration speeds maintenance, while the broad -40 to 60 °C range supports deployments across diverse facilities, delivering a measurable return on investment through safer, faster servicing and extended component life.
