FAQs

The 1433 is a 20A, 125V back-wire plug with a 5-20P NEMA configuration, designed for industrial equipment requiring a two-pole, three-wire grounding receptacle. It aligns with common control panels and 125V circuits, ensuring straightforward integration with existing gear and cords within the 0.38–1 inch diameter range.
Power must be shut off before wiring. Strip wires to the recommended length for back-wire termination, insert into the appropriate terminal, and tighten to the 14 lbf-in torque specification to ensure a secure, reliable connection. Verify polarity and perform a continuity check prior to energizing the circuit.
Yes. The plug uses corrosion-resistant nickel-plated brass contacts and a corrosion-resistant nylon body, designed to withstand harsh environments typical in industrial settings and washdown areas, thereby improving longevity and reducing maintenance cycles.
The 1433 is cULus Listed, indicating compliance with UL safety standards for industrial wiring devices. This certification supports regulatory acceptance, safer installations, and reliability in workplace environments that require validated electrical components.
The combination of corrosion resistance, robust contacts, and secure wiring reduces maintenance frequency and downtime. The result is improved uptime for critical equipment and lower lifecycle costs, making the Eaton 1433 a cost-effective choice for demanding industrial installations.
