Quick Summary
Eaton TP403PF square outlet box provides a durable steel enclosure for 4-inch conduit runs in industrial electrical installations. In the field, space constraints, grounding integration, and varied knockout patterns can slow panel builds, complicating routing and wiring. It meets NEC/CEC standards for ordinary locations, with Canadian certification documentation available. By combining rugged welded steel construction with a practical 4" box size and proven grounding features, this enclosure supports efficient, compliant installations in control panels and equipment rooms, while reducing rework and maintenance costs for steel square boxes and Crouse-Hinds series solutions.
