FAQs
To install the AHL1420P, prepare the back-wiring terminals for #16-8 AWG conductors, connect each conductor to its corresponding terminal per the L14-20 pinout, and tighten to the manufacturer's recommended torque. Ensure the unit is oriented for correct polarity, then mount and secure the locking flange to prevent accidental disconnection. Verify continuity and insulation after termination and test under load to confirm secure operation.
Yes. The AHL1420P is a three-pole, four-wire locking plug designed for L14-20 configurations, rated at 20A and 125/250V. It is suited for industrial panels, transfer switches, and equipment hookups that require a secure, vibration-resistant connection with locking capability. Its nylon body and Ultra Grip mechanism enhance compatibility with standard industrial receptacles.
The AHL1420P carries RoHS compliance, which restricts hazardous substances, and is cULus Listed NOM, indicating UL and Canadian safety recognition for the product. These certifications support regulatory compliance in North American installations and facilitate safer audits, aligned with industrial safety standards.
The device operates from -40 to 60 °C (-40 to 140 °F), suitable for harsh industrial environments and outdoor or dirty facilities. The nylon body provides chemical and impact resistance, maintaining performance across temperature fluctuations and demanding site conditions without frequent replacements.
Ultra Grip locking devices reduce unintended disconnections and minimize maintenance downtime by ensuring a secure, vibration-resistant connection. The back-wiring capability speeds installation and reduces termination errors, lowering field labor costs. For capital projects, this translates to faster commissioning, fewer service calls, and improved uptime for critical manufacturing lines.
