Eaton TP451PFRED Square Outlet Box - 30.3 cu in capacity

Welded steel construction delivers rugged durability for industrial enclosures. The TP451PFRED uses a 4-inch square box with a 2-1/8 inch depth and a 30.3 cubic inch capacity, maximizing wiring space without expanding footprint. This geometry supports complex terminations in control panels and aligns with standard sizes used in Eaton’s Crouse-Hinds steel square box family, reducing part variety and project risk. Grounding reliability is enhanced by a dedicated ground screw with pigtail lead, simplifying safe fault paths and accelerating commissioning. This feature reduces rework by guaranteeing a solid, code-compliant equipment ground in every enclosure, even in retrofit scenarios where grounding routes are constrained. VMS stud bracket included aids quick mounting to structural members, improving alignment and reducing hardware handling during installation, especially in tight panels or crowded electrical rooms. Knockout versatility: side, bottom, and end knockouts provide flexible routing for 1/2 and 3/4 inch conduits with EKO options, enabling clean wiring runs and fewer field adaptations. Conduit (no clamps) designation means you can pair with your preferred external clamps, streamlining vendor coordination and enabling faster field upgrades. Red color improves visibility in dense equipment spaces and supports color-coded wiring schemes used in industrial installations. NEC/CEC compliance ensures regulatory alignment for ordinary locations, reducing compliance risk across multiple sites.
