Welded steel construction provides rugged protection against impact and dust ingress, reducing field damage and warranty risk while meeting NEC/CEC requirements in non-hazardous locations. This translates to lower maintenance costs and fewer unexpected downtime events in high-cycle manufacturing lines. The 4" box footprint, 2-1/8" depth, and 30.3 cubic inch capacity give engineers ample space for conductors, reducing the need for aggressive wire packing and enabling cleaner terminations in control panels. The configuration includes (6) side knockouts and (4) additional E side knockouts plus (2) bottom knockouts, plus bottom E knockouts, enabling flexible conduit routing and faster installation, especially when retrofitting existing cabinets. Ground bump and steel construction improve grounding reliability and code compliance across mixed-spec environments. AC/MC clamps compatibility supports quick, secure cable entries with minimal rework during panel upgrades or migrations. These features collectively reduce installation time, improve wiring quality, and lower lifecycle costs in automation projects.

FAQs
TP4Q10 is ideal for non-hazardous locations where reliable terminations and durable protection are required. Its welded steel construction, 30.3 cu in capacity, and multiple knockouts support clean wiring runs in machine panels and control cabinets, helping minimize field modifications and downtime.
TP4Q10 offers (6) side knockouts and (4) side E knockouts, plus (2) bottom knockouts and (2) bottom E knockouts, along with 2 cable knockouts. This configuration provides flexible conduit routing for complex wiring while maintaining a compact 4" box footprint suitable for tight panel spaces.
TP4Q10 is rated for Ordinary/Non-Hazardous Locations and adheres to NEC/CEC standards. It is not specified for hazardous (explosive) atmospheres. For hazardous locations, a variant with appropriate ratings or enclosures designed for those classifications should be selected.
The TP4Q10 complies with NEC/CEC standards and is UL certified for steel square outlet boxes. It is intended for ordinary/non-hazardous locations, ensuring code-compliant grounding, wiring practices, and safe enclosure integrity across cross-border installations.
Key considerations include leveraging the ground bump for solid grounding, using AC/MC clamps compatible with the knockouts for quick entry, and planning knockouts to minimize wire bending and conductor fill. The welded construction and 2-1/8" depth help maintain panel density, while the 30.3 cu in capacity accommodates future cable expansion without reworking the enclosure.
