Eaton TP404 Square Outlet Box - NEC/CEC Compliance

Construction durability is achieved through welded steel, delivering a rigid enclosure that resists impacts and maintains enclosure integrity in demanding environments. This stability translates into lower field rework and longer service life in machine controls and production equipment. The benefit is tangible: fewer enclosure-related failures and reduced maintenance costs over the life of the installation. The TP404 supports flexible conduit routing with a comprehensive knockout pattern, including side knockouts and bottom knockouts, enabling clean wiring runs and faster termination. With a 22 cubic inch capacity and a 4-inch square footprint, technicians gain efficient space planning and room for essential wiring without oversized boxes. The combination of (8) 1/2 in, (4) 1/2 in, (1) 3/4 in E side knockouts and (2) 1/2 in, (2) 1/2 in, (1) 3/4 in E bottom knockouts reduces the need for adapters and extension rings. Conduit (no clamps) simplifies hardware selection and minimizes installation time. This enclosure is compliant with NEC/CEC standards for ordinary/non-hazardous locations, giving customers confidence in code readiness and safety. The TP404 is compatible with standard 4-inch square box installations, supporting quick swap-ins in legacy control cabinets and upcoming upgrades. Installed as part of Eaton Crouse-Hinds steel square boxes, it contributes to consistent wiring practices and streamlined procurement across projects.
