FAQs
Installation begins with mounting the box using the S or stud brackets provided, then routing conductors through the appropriate knockouts: eight side KO positions for flexible conduit routing, plus bottom and end knockouts for power and device connections. A ground screw with a pigtail lead is included to establish a solid ground path. Conduit connections are supported as conduit (no clamps) to reduce hardware, and the box is pre-wired for straightforward grounding and termination.
The TP411PFRED is designed to meet NEC/CEC standards and is suitable for Ordinary/Non-Hazardous Locations. Canadian certification is available through the referenced UL listings, supporting cross-border deployments. This combination helps streamline procurement and compliance audits for North American projects, reducing risk when sourcing enclosures for panel assemblies.
This 4-inch steel square box is ideal for control panels, junction boxes, and equipment enclosures requiring reliable terminations in non-hazardous environments. Its large 50.0 cu in capacity accommodates multiple conductors and devices, while the welded construction and grounded mounting support long service life in busy manufacturing environments.
Consider the box’s knockouts layout, mounting brackets, and grounding features to minimize additional fittings and clamps. NEC/CEC compliance plus optional Canadian certification simplify regulatory checks, while the ground screw with pigtail and conduit-ready design reduce install time and material costs, delivering faster project turnover and clearer documentation for audits.
The welded steel construction provides durable enclosure protection against field stresses, reducing maintenance calls and unexpected downtime. The ample 50 cu in capacity lowers the need for multiple boxes, while the integrated grounding and mounting options speed future upgrades or reconfigurations, delivering measurable ROI through reduced labor and fewer part substitutions.
