Eaton TP405 Square Outlet Box with 22 cu in, NEC/CEC
Part Number: TP405
Quick Summary
The Eaton TP405 Square Outlet Box provides a durable junction housing for industrial control panels and conduit runs. Engineers often face cramped enclosures that cap conductor counts and complicate wiring. This product aligns with NEC/CEC compliance and is designed for ordinary/non-hazardous locations, helping you meet code without overdesign. UL certification references support reliable field validation, while its 22 cu in capacity accommodates a practical mix of conductors and devices. Made from steel with drawn construction, it accepts multiple knockouts for flexible wiring and fast installs, reducing labor time and field rework. Ideal for 4-inch steel square box installations, it pairs with Crouse-Hinds accessories to streamline projects.

Feature: 4-inch steel square box with 22 cubic inches of internal capacity. Business Impact: Provides ample space for conductors and devices, minimizing overcrowding and field rework while meeting common enclosure standards. Application: Supports industrial control panels, wall-mounted wiring, and equipment racks where a compact, code-compliant enclosure is required. Feature: Conduit (no clamps) design. Business Impact: Reduces part counts and procurement time; speeds up field installation by letting electricians apply existing clamps or connectors. Application: Ideal for standard conduit runs in manufacturing facilities and service panels where clamps are sourced separately. Feature: Knockout layout (side: four 1/2 in, six 1/2 in, one 3/4 in; bottom: three 1/2 in, two 3/4 in). Business Impact: Enables flexible wiring schemes and quick customization without modifying the box. Application: Quick integration of diverse conduit entries for control circuitry and power distribution in industrial enclosures. Feature: Drawn steel construction. Business Impact: Delivers rugged protection against impact and wear in harsh environments, extending lifecycle and reducing maintenance. Application: Suitable for factory floors, machine rooms, and outdoor-rated indoor spaces requiring durable enclosures. Feature: Certifications and standards alignment (NEC/CEC; Ordinary/Non-Hazardous Locations). Business Impact: Ensures code-compliant installations and provides confidence for audits; UL certification references add validation. Application: Fits typical North American electrical installs with compatible accessories and covers from the Crouse-Hinds lineup.

FAQs
For TP405 installations, plan for a 4x4 in footprint with 22 cu in of internal space, use the side and bottom knockouts as required, and source conduit clamps separately since this model is listed as conduit (no clamps). This reduces part counts while preserving code-compliant wiring routes.
Yes. The TP405 is designed for ordinary/non-hazardous locations and adheres to NEC/CEC standards. This alignment simplifies code compliance during audits and project handoffs, while supporting reliable, durable enclosures for commercial and industrial environments.
TP405 excels in industrial control panels, wall-mounted wiring, and junctions requiring robust metal enclosures. Its 22 cu in capacity accommodates multiple conductors and devices, and the 4x4 footprint integrates with standard panels and Crouse-Hinds accessories for streamlined installations.
TP405 is compatible with Crouse-Hinds steel square boxes and covers, extension rings, and standard 4-inch square box accessories. Although it ships without clamps, you can pair it with Eaton-approved conduits and connectors to tailor the final enclosure to your wiring plan.
The TP405 features a deliberate knockout pattern (side and bottom) that supports flexible routing and quick field changes. This reduces wire routing time, minimizes the need for drilling or modification, and improves maintenance efficiency when reconfiguring panels or adding circuits.
