Eaton TP620 Octagon Concrete Box 4-in Steel - NEC/CEC

The TP620 uses a durable steel octagon box with a 4-inch box size and 23 cubic inches of capacity, delivering reliable protection for electrical connections in concrete installations. This translates to fewer field failures and lower maintenance costs, providing a clear business case for projects with long-term uptime requirements. The design includes 1/2 inch and 3/4 inch knockouts in a single row, enabling flexible wiring without the need for aftermarket adapters, which speeds installation and reduces material waste on site. In practice, this means installers can route conductors efficiently around tight spaces while maintaining a clean, code-compliant enclosure. The Ordinary/Non-Hazardous location rating ensures safe use in standard industrial facilities without requiring explosion-proof or specialized housing, saving upfront equipment costs. NEC/CEC standards alignment supports code-compliant designs and smoother inspections, minimizing project delays and rework. UL Canada certification further validates cross-border applicability, simplifying procurement for multi-country builds. Compatibility with the Crouse-Hinds line and 4-inch steel outlet boxes helps standardize enclosures across facilities, reducing training time and inventory complexity. Overall, the TP620 delivers improved installation velocity, durable performance in concrete environments, and predictable lifecycle costs for control panels and distribution nodes.
