Eaton TP411 Square Outlet Box - 46 cu in NEC/CEC Certified
Part Number: TP411GRED
Quick Summary
The Eaton TP411 Square Outlet Box provides sturdy enclosure for surface conduit terminations in industrial electrical installations. When space is tight or mounting is complex, panel designers struggle to fit reliable protection and easy access. It carries NEC/CEC compliance and is suitable for Ordinary/Non-Hazardous Locations, with Canadian certification reflected in UL listings. Built for steel square boxes and conduit systems, it helps installers speed wiring, reduce field rework, and improve panel reliability. Our engineers value the 46 cubic inch capacity and the welded construction, which maintain enclosure integrity in demanding environments. The 4 in box size with flexible side and bottom knockouts supports rapid routing of cables and future upgrades.

FAQs
TP411 is designed for conduit without integrated clamps; clamps are not included and must be added per the conduit type used. The enclosure provides standard knockouts that accommodate common conduit fittings, enabling straightforward installation with existing hardware. This approach reduces part variety, speeds up field assembly, and keeps wiring paths clean while maintaining compliance with NEC/CEC requirements.
TP411 includes side knockouts totaling twelve 1/2 inch openings plus one 3/4 inch C, and bottom knockouts with four 1/2 inch openings plus one 3/4 inch C. This mix supports versatile cable routing for typical 4-inch square boxes, allowing engineers to tailor wiring routes to equipment layouts without extra adapters or fittings.
No. The TP411 is specified for Ordinary/Non-Hazardous Locations and is designed for general industrial environments. For hazardous or potentially explosive atmospheres, a different enclosure with appropriate certification and enclosure rating would be required, such as explosion-proof or intrinsically safe variants that are specifically rated for those conditions.
TP411 carries NEC/CEC compliance and UL Canadian certification, aligning with North American electrical codes and cross-border requirements. These certifications help ensure electrical safety, simplify regulatory approvals, and reduce project risk when sourcing enclosures for multi-site deployments, especially in facilities spanning the US and Canada.
The TP411 delivers tangible value through durable welded steel construction, 46 cubic inches of capacity, and a 4" box footprint that fits compact installations. The complete knockouts offer flexible wiring options, reducing the need for adapters and rework, while NEC/CEC compliance lowers compliance risk. Overall, it speeds installation, improves reliability, and lowers lifecycle costs in control panels and electrical housings.
