Eaton TP252 Switch Box - 18 cu in Steel, NEC/CEC
Part Number: TP252
Quick Summary
The Eaton Crouse-Hinds series TP252 switch box is a rugged steel enclosure for mounting switches and conduit in electrical control installations. Engineers often wrestle with enclosures that fail under harsh environments or limit future expansion. This TP252 model complies with NEC/CEC standards and is suitable for ordinary/non-hazardous locations, giving teams a dependable baseline for commercial or light industrial projects. Its 18 cubic inch capacity, 3-1/2 inch depth, and 2 x 1/2 inch knockouts support flexible wiring schemes while maintaining a compact footprint. The steel construction and gangable design reduce total enclosure count on complex panels and simplify future upgrades, lowering lifecycle costs. With standard conduit options and durable steel, it adapts to evolving electrical layouts without the need for special accessories.

FAQs
TP252 supports standard conduit entry with two end knockouts, two side knockouts, and one bottom knockout, all 1/2 in, and is designed for conduit without clamps. This arrangement gives flexible routing for power and control wiring. The unit is gangable and ships with mounting ears, enabling rapid surface or backplane installation in compact panels and multi-box configurations.
Not for hazardous locations. The TP252 is listed as Ordinary/Non-Hazardous Locations under NEC/CEC standards, which means it’s designed for general purpose environments without explosive atmospheres. If your application requires hazardous-area protection, choose enclosures with appropriate ratings (for example explosion-proof or dust-ignition-protected) and verify local codes before installation.
NEC/CEC standard compliance is specified for the TP252, ensuring electrical safety and installation compatibility within North American codes. Canadian certifications are also referenced in the product documents, and UL listings support cross-border use. Always confirm the latest listings and any site-specific requirements before field deployment.
Yes. The TP252 is explicitly designed to be gangable, reducing the number of enclosures required in panel assemblies. When used with ears and compatible hardware, multiple boxes can be mounted together to create a larger, shared enclosure. This simplifies wiring, shortens installation time, and lowers overall material costs on complex control panels.
Dimensions are listed as 3.5 in wide, 3 in high, and 2 in deep with a 3-1/2 in depth specification noted in the spec sheet; weight is 0.76 lb. The 18 cubic inch capacity accommodates typical starters, relays, and conduit fittings. Plan for surface or back-mount installation and ensure sufficient space for knockouts and mounting ears.
