The 4-inch steel square box delivers a generous 30.3 cubic inch capacity, enabling secure terminations for complex wiring runs and reducing the need for field extensions, which translates to faster panel wiring and fewer rework cycles. The MSB stud bracket paired with welded steel construction provides a rigid, vibration-resistant mounting platform that improves reliability in demanding environments and simplifies alignment when integrating with existing control panels. Multiple knockouts (two side 1/2 inch, two bottom 3/4 inch, and end knockouts including EKO options) give installers flexible conduit routing without resorting to adapters, minimizing labor and clamp costs while supporting diverse installation topologies. Ground screw installed standardizes grounding practices, saving time and ensuring consistent safety. The red finish enhances visibility for maintenance crews, aiding rapid inspections and reducing accidental impacts in busy facilities. NEC/CEC compliance and ordinary/non-hazardous area rating guarantee regulatory alignment for most industrial applications, while the option to reference Canadian certification materials supports cross-border projects and audits.

FAQs
Mounting is simplified by the MSB stud bracket designed to align with standard panel studs. Secure the box with the included hardware, ensure the 4-inch box sits square, and use the welded steel body for rigidity. The ground screw is pre-installed to expedite grounding, and the 30.3 cubic inch interior supports multiple conductors, reducing the need for rework during relay or terminal block upgrades.
The TP4MSBGRED provides side knockouts at 1/2 inch, bottom knockouts at 1/2 and 3/4 inch, and end knockouts including EKO options. This mix offers flexible conduit entry points for various layouts, enabling direct conduit routing to control panels or machine enclosures. Conduit can be run without clamps, simplifying installation in tight spaces and reducing hardware costs.
This enclosure is designed for ordinary and non-hazardous locations, aligned with the area classification stated for the product. It is NEC/CEC compliant for general industrial use, but it should not be used in hazardous environments unless specified for such ratings. Always verify local codes and safety requirements before deployment in a plant.
The TP4MSBGRED meets NEC/CEC standards and is intended for ordinary/non-hazardous locations. Documentation is available for Canadian certification via UL references, and Eaton provides catalogs and spec guides to support compliance reviews. Use these references during audits and cross-border commissioning to demonstrate regulatory alignment.
Choosing the TP4MSBGRED delivers measurable value: higher wiring capacity with 30.3 cu in interior, faster installation through MSB mounting and pre-installed ground screw, and enhanced reliability from welded steel construction. The multiple knockouts reduce configuration time, while the red visibility aids maintenance checks, contributing to lower lifecycle costs and fewer field modifications in busy facilities.
