Eaton TP677 Switch Box - Steel, 14 cu in, NEC/CEC
Part Number: TP677
Quick Summary
Eaton TP677 switch box provides a durable steel enclosure for conduit connections in industrial panels. This rugged unit helps electricians avoid field-fit failures by delivering precise dimensions, gangable capability, and reliable mounting options. Operators often struggle with undersized or non-gangable boxes that complicate wiring, create clearance issues, and slow installation; TP677 addresses these pain points with a compact 3 in depth, 2 in width, and 2-3/4 in depth profile plus set 5/8" S brackets. The product aligns with NEC/CEC standards and ordinary/non-hazardous location classifications, ensuring dependable compliance across North American installations. For integrators, its compatibility with standard conduit layouts and the proven Crouse-Hinds lineage delivers cost-efficient, scalable protection for electrical terminations in panels and enclosures.

Feature: Steel construction delivers rugged protection for electrical terminations in harsh environments. Business impact: reduces risk of damage from impact or corrosion, lowering repair costs and downtime. Application: ideal for steel switch boxes in industrial panels where durability and long life are essential. Feature: 14 cubic inch capacity with gangable 2-3/4 inch depth and 3/4 inch knockouts. Business impact: accommodates a range of components without crowding, speeding assembly and improving reliability. Application: suitable for compact control cabinets and enclosures requiring moderate packing density. Feature: Conduit (no clamps) with End, Side, and Bottom knockouts, plus bracket set S, 5/8 inch. Business impact: flexible routing and straightforward mounting to streamline installation and reduce hardware needs. Application: preferred in retrofit upgrades and new builds where conduit routing varies. Feature: Material is steel with a 0.67 lb weight. Business impact: lightweight yet robust, facilitating handling during site installs and reducing shipping costs. Application: supports rapid deployment in ordinary locations, aligning with NEC/CEC compliance and standard switch-box workflows. Feature: Area classification Ordinary/Non-Hazardous Locations and NEC/CEC standards. Business impact: clear regulatory alignment lowers risk of non-compliance and expedites permit-ready documentation. Application: widely used in general industrial, commercial, and light manufacturing settings where safe, code-compliant enclosures are required. This combination supports cross-compatibility with Eaton’s Crouse-Hinds series and standard mounting patterns, reducing vendor complexity and accelerating project timelines.

FAQs
To install TP677, mount the gangable steel enclosure using the S bracket set (5/8 in) for secure alignment. Run conduit through the appropriate knockouts (end, side, or bottom) without clamps, then terminate conductors inside the 14 cu in capacity cavity. Verify NEC/CEC compliance for ordinary locations and ensure clearances match panel specifications. The box’s 3 in length, 2 in width, and 2-3/4 in depth support compact layouts while maintaining serviceability for terminations and future upgrades.
TP677 is a gangable steel switch box with a 14 cubic inch capacity, 3 in length, 2.75 in height, and 2 in width. It features one end knockout and one side knockout at 3/4 in, and one bottom knockout at 1/2 in. The bracket style is S with a 5/8 in set, and the conduit entry is provided without clamps. The enclosure is designed for ordinary/non-hazardous locations and complies with NEC/CEC standards.
Yes. The TP677 is explicitly rated for Ordinary/Non-Hazardous Locations and conforms to NEC/CEC standards, making it appropriate for general industrial and commercial wiring scenarios. Its steel construction provides robust protection for terminations in non-explosive environments, and its gangable design supports modular expansion in panel assemblies without compromising code compliance or safety considerations.
TP677 carries NEC/CEC compliance for North American installations and is associated with Canadian certification references through related product documentation and UL certification pages. For cross-border projects, this means you can leverage the same enclosure in both U.S. and Canadian facilities, simplifying procurement and validating conformity during inspections while maintaining consistent material and dimensional specifications.
TP677 mitigates common panel installation challenges by delivering a compact, gangable enclosure with defined knockouts (end, side, bottom) and a clear 14 cu in capacity. Its standard S bracket and conduit-ready design reduce field fabrication, lower labor time, and minimize the need for adapters. The result is faster wiring, easier future expansions, and reliable protection for conductors in ordinary-location environments.
