The TP452 combines a robust welded steel construction with a practical 4-inch square footprint, delivering durable protection for splices and terminations in demanding environments. Feature → Business Impact → Application: welded steel enclosure translates to long service life and reduced field maintenance, which lowers downtime and total cost of ownership in panel upgrades or new machinery installations. The 30.3 cubic inch capacity supports multiple conductors and connectors, enabling faster terminations and fewer extensions in small control panels and electrical cabinets. NM clamps and the VMS bracket simplify wiring and mounting, cutting installation time while improving cable management and reliability in factory floors. Side knockouts include two 1/2 in, one 1/2 in E, and one 3/4 in E, with a bottom 1/2 in knockout, providing flexible conduit routing for stair-stepped installations or retrofits. Four cable knockouts further support versatile routing, reducing the need for adapters and field fabrication. The 4 in by 4 in by 2-1/8 in form factor fits standard mounting schemes, facilitating compatibility with existing enclosures and covers. The enclosure is designed for ordinary/non-hazardous locations, aligning with NEC/CEC compliance and reducing risk during audits. Overall, this box enables faster project delivery, safer terminations, and scalable configurations for growing industrial systems.

FAQs
For reliable TP452 installation, verify the 4x4 in footprint and confirm the side and bottom knockouts meet your conduit plan. Use NM clamps to secure conductors and the included VMS bracket to mount the box rigidly to the enclosure wall. Ensure the box is oriented for cable entry and that all terminations comply with NEC/CEC wiring methods. Use appropriate gaskets or covers to maintain enclosure integrity in ordinary locations.
TP452 features side knockouts: (2) 1/2 in, (1) 1/2 in, (1) 3/4 in E, plus a bottom knockout (1) 1/2 in and a total of four cable knockouts. This arrangement supports flexible conduit routing and wiring layouts, enabling you to bring conductors from multiple directions with minimal field modification. Plan routing to minimize bending radii and ensure proper strain relief and ground continuity.
Yes. TP452 is designed for ordinary/non-hazardous locations and complies with NEC/CEC standards, making it suitable for control panels, electrical cabinets, and machine enclosures in non-hazardous industrial environments. Its welded steel construction provides durability under typical factory conditions, while NM clamps and knockouts support robust, code-compliant wiring in these settings.
TP452 carries NEC/CEC standards and is referenced for UL-certified steel square boxes, covers, and extension rings, supporting compliance in North American installations. The Ordinary/Non-Hazardous Locations area classification further confirms suitability for standard industrial environments. This combination helps with regulatory audits, reduces risk of non-compliance penalties, and streamlines procurement for projects requiring recognized safety and performance benchmarks.
The TP452 delivers measurable ROI through reduced field rework, faster installation, and longer service life. Welded steel construction resists impact and corrosion, NM clamps simplify wiring, and the VMS bracket speeds mounting. With a 30.3 cubic inch capacity and flexible knockouts, it supports scalable, modular upgrades for control panels, lowering total cost of ownership and downtime during modernization projects.
