FAQs
The 5366 accepts solid #16-12 AWG conductors via back-wire and provides a secure screw-terminal option. Proper stripping length and clean insertion ensure a solid clamp, reducing the chance of loose connections in vibration-prone panels. This makes field wiring faster and more reliable for industrial control circuits.
Yes. The 5366 is a two-pole, three-wire grounding straight-blade plug rated at 20A and 125V, designed for NEMA 5-20P configurations. It aligns with standard industrial power layouts, enabling safe and consistent connections in control panels and equipment enclosures.
The plug carries UL NOM Federal Specification Classification 6221 02, confirming compliance with established electrical safety and performance criteria for industrial wiring devices, which helps streamline regulatory approvals and supplier qualification in manufacturing environments.
The 5366 features a nylon body with brass contacts, designed for back-wire or screw termination, and supports #16-12 AWG with a cord range of 0.33–0.66 inches. Its robust nylon/Brass construction and the standard configuration help ensure compatibility with common panel cutouts and protective enclosures used in industrial facilities.
With durable nylon construction, secure terminations, and vibration resistance, the 5366 reduces field rework and downtime, improving maintenance efficiency. The combination of core-pack packaging and standard wiring compatibility also lowers stocking costs and speeds installation, delivering cost savings over long project lifecycles in heavy-duty manufacturing environments.
