FAQs
AH5666 supports back-wire and screw termination for #18-12 AWG conductors. For back-wire, strip the insulation per manufacturer guidelines and insert into the clamp until seated, then verify polarity. For screw termination, loosen terminal screws, insert conductors fully, tighten to the recommended torque (14 in‑lb), and retorque after a brief tug test. Ensure proper strain relief and enclosure clearance.
The AH5666 is rated for 15A at 250V and uses a NEMA 6-15P configuration. It is a two-pole, three-wire grounding device with back-wire or screw termination. This combination supports industrial equipment such as motors and control panels with reliable, code-compliant power connections in rugged settings.
Yes. AH5666 is designed for industrial wiring and control panels, featuring extra heavy-duty industrial specification grade construction, brass contacts, and a nylon body. Its RoHS compliance and UL NOM 6221-02 certification meet stringent safety and environmental standards, while its back-wire/screw options and 0.33–0.66 in cord range support flexible, durable panel wiring.
AH5666 carries RoHS compliance and UL NOM Federal Specification Classification 6221 02, signaling conformance to environmental and safety standards. This matters for regulatory compliance in many industrial facilities, ensures safer handling and disposal practices, and supports traceability during audits. The certification set reduces risk when integrating into regulated power distribution systems.
The combination of brass contact material and nylon body provides durable, corrosion-resistant performance with low contact resistance over time, reducing re-termination and maintenance needs. Its robust design, secure mating (14 in‑lb torque), and compatibility with common #18-12 AWG wiring contribute to lower replacement frequency and favorable total cost of ownership in high-use industrial environments.
