Welded steel construction delivers a rigid enclosure that resists impact in busy plant spaces. This durability reduces field repairs and replacement costs, improving total cost of ownership for automation cabinets and machine wiring. It’s well suited for control panels and junction boxes in harsh industrial environments. Multiple knockouts and no clamps provide flexible wiring options. The side and bottom knockout patterns enable straightforward conduit routing for motor control centers and machine frames, reducing the need for clamps and adapters and speeding install times. The included ground screw with pigtail simplifies grounding practices and reduces field wiring steps, supporting safety-critical installations and reliable fault paths in automated systems. With a 30.3 cubic inch capacity, the interior accommodates conductors and splices without crowding, improving termination reliability and future rework flexibility. The product’s NEC/CEC alignment and Ordinary/Non-Hazardous area classification ensure compliant, low-risk installations, while compatibility with standard 4-inch covers and fittings enhances field adaptability and lifecycle value.

FAQs
The TP403PFA is a 4-inch square welded steel box with multiple knockouts (side and bottom) and conduit entries that do not require clamps. When installing, plan for eight 1/2 in and four 1/2 in side knockouts plus a 3/4 in E entry, plus bottom knockouts. Use the included ground screw with pigtail to ensure proper grounding, and verify the enclosure is suitable for Ordinary/Non-Hazardous locations per NEC/CEC.
TP403PFA aligns with NEC/CEC standards and is classified for Ordinary/Non-Hazardous Locations. This matters because it ensures compliance with general electrical installation codes, reduces regulatory risk for machinery and control panels, and supports steady long-term performance in typical industrial environments where hazardous atmospheres are not present.
Yes. The 4-inch square box provides 30.3 cubic inches of interior space, accommodating conductors and terminations for many automation devices. Its welded steel construction delivers durability in busy manufacturing lines, while its conduit entries and ground provision support reliable, code-compliant panel assemblies with easier future rework of wiring layouts.
The TP403PFA includes a ground screw with a pigtail lead, simplifying the grounding process for enclosure installations. Connect the pigtail to the equipment grounding conductor and attach the screw to the box or mounting surface as required by your panel design. This setup provides a robust fault path and reduces installation steps compared to separate grounding hardware.
Choosing TP403PFA yields a favorable lifecycle ROI through robust welded steel construction, reduced maintenance needs, and flexibility from multiple knockouts and clamps-free conduit entries. The box’s compatibility with standard 4-inch covers simplifies upgrades, and its compliant NEC/CEC profile lowers the risk of non-compliance costs while delivering reliable long-term performance in ordinary locations.
