Quick Summary

Eaton TP423 Square Outlet Box is a rugged steel enclosure designed for protecting wiring connections in industrial conduit systems. Too often, installation delays stem from limited knockout options and insufficient volume for field wiring. This box meets NEC/CEC standards and is rated for Ordinary/Non-Hazardous Locations, providing reliable performance in harsh factory environments. It also offers durable welded construction and a 4 x 4 inch footprint that fits standard installation spaces without compromising capacity. With a 22 cubic inch capacity and a 1-1/2 inch depth, it delivers essential enclosure real estate while supporting VMS mounting and conduit entries without clamps. These traits translate to faster installs, predictable code compliance, and lower lifecycle costs in automation facilities.

Feature: Welded steel construction delivers a rigid, durable enclosure that resists flexing and impulse damage in busy industrial spaces. Business impact: longer service life for conduit connections reduces maintenance and replacement costs while improving system uptime. Application: ideal for control panels, motor starters, and power distribution housings in factory floors where vibration and moisture are concerns. Feature: Conduit entry without clamps simplifies routing and eliminates bulky clamp hardware. Business impact: faster installations, fewer parts to stock, and clearer interior layouts that speed wiring and inspections. Application: suitable for compact control panels and short runs in automated lines where space is at a premium. Additionally, the absence of clamps reduces potential corrosion sites and helps meet enclosure integrity requirements in challenging environments. Feature: VMS bracket style and 4-inch box footprint provide flexible mounting and clean panel aesthetics. Business impact: reduces mounting complexity and speeds enclosure integration with backplanes and wall installations. Application: ideal for machine control zones, industrial cabinets, and panel assemblies in manufacturing facilities. Feature: Multiple knockouts on the sides and bottom enable versatile conduit routing for 1/2 inch and 3/4 inch entries. Business impact: minimizes the need for adapters and rework, improving field wiring efficiency. Application: supports diverse wiring schemes in electrical rooms, OEM equipment, and process lines. Feature: NEC/CEC compliance and Ordinary/Non-Hazardous Locations rating ensure safe, code-conforming installations. Business impact: lowers regulatory risk and accelerates project sign-offs. Application: suitable for general industrial facilities, automation equipment, and electrical distribution in non-hazardous environments.

FAQs

Begin with a clean, square mounting surface and mark for the 4x4 in footprint. Use the VMS mounting options to secure the enclosure, then route conductors through the side or bottom knockouts (6x 1/2 in, 3x 1/2 in, 1x 3/4 in E on sides; 2x 1/2 in, 2x 1/2 in, 1x 3/4 in E on bottom) with conduit entering without clamps. Seal as needed and mount covers to complete the enclosure.
Yes. The TP423 is designed for Ordinary/Non-Hazardous Locations and complies with NEC/CEC standards, making it appropriate for general industrial environments where standard electrical codes apply. Its welded steel construction and standard knockouts support safe, code-conforming terminations in panels and equipment enclosures.
Ideal for control panels, machine junctions, and power distribution housings in factory automation, conveyors, and robotics cells. The 4x4 in footprint, 22 cubic inch capacity, and VMS bracket style enable versatile mounting in tight spaces, while multiple knockouts accommodate diverse conduit routing schemes common in manufacturing facilities.
The TP423 aligns with NEC/CEC standards and is rated for Ordinary/Non-Hazardous Locations, ensuring regulatory compliance for non-hazardous industrial environments. Its welded steel construction and conduit entry without clamps further support durable, code-compliant installations in typical factory facilities.
The clamp-free conduit entries and welded steel design reduce fastener count and setup steps, speeding initial installation. The robust construction minimizes jiggle-related wear, lowering maintenance costs and extending service life for electrical terminations in demanding environments; this translates to higher overall equipment uptime.
