FAQs
For back-wire terminations, ensure conductors are clean and properly stripped to the recommended length, insert into the back-wire clamps, and torque screws to 30-35 in-lbf to achieve a secure clamp without damaging conductors. This method reduces field errors and speeds up installation in control panels and enclosures.
The 5712N is rated for 50 A at 125 V and uses brass contact material with a nylon body, providing robust current handling, resistance to wear, and long-term reliability for high-load devices such as motors and machinery feeding in manufacturing environments.
Yes. It uses a two-pole, three-wire grounding configuration with NEMA 5-50P compatibility and back-wire screw terminations, facilitating integration with common industrial power distribution layouts and minimizing panel adaptation risk.
The plug is cULus Listed, NOM certified, and aligned with Federal Specification Classification 6221 02. These certifications support NEC/UL compliance, enable broader product acceptance, and simplify regulatory audits across North American facilities.
The auto-grip design and secure screw back-wire terminations reduce loose connections and maintenance calls, improving uptime. Its durable nylon/brass construction resists wear, lowering replacement frequency and contributing to lower total cost of ownership over the equipment lifecycle.
