FAQs

AH5366 supports back-wire terminations for #16-12 AWG conductors with a cord diameter of 0.33-0.66 inches, plus a screw-terminal option. To install, power off the circuit, prepare the conductors, insert into the back-wire clamps or tighten the screws to the manufacturer’s torque spec of 14 lbf-in, and verify polarity and grounding. The result is a secure, vibration-tolerant connection suitable for industrial equipment.
AH5366 is rated for 20A at 125V and follows the 5-20P NEMA configuration. It uses brass contacts and a Nylon body, offering good conductivity and chemical resistance. The device is RoHS compliant and UL listed, with NOM certification and Federal Specification 6221 02. These specifications support reliable operation in industrial controls, with controlled torque and durable performance.
Yes. The two-pole, three-wire grounding receptacle, extra heavy-duty industrial specification grade, and straight blade design make AH5366 well-suited for control panels, conveyors, motors, and other industrial equipment. Its robust nylon body and brass contacts resist wear and corrosion, while back-wire wiring reduces field install time in dense panel configurations, delivering consistent performance in vibration-prone environments.
AH5366 carries UL listing, NOM certification, and Federal Specification Classification 6221 02, along with RoHS compliance. These certifications help streamline regional approvals, support safety and environmental requirements, and minimize the need for additional qualification testing when deploying across multiple sites.
The AH5366’s durable brass contacts and nylon housing reduce wear, rework, and replacement frequency, contributing to lower maintenance costs. Fast, secure back-wire terminations save installation time, reducing labor costs during panel wiring. In multi-site deployments, standardized components improve procurement efficiency and spare parts availability, delivering measurable uptime gains and predictable maintenance budgets.
