FAQs
The TP178 measures 2 in depth, 3 in height, and 2.5 in width. It features one 1/2 in side knockout and one 1/2 in bottom knockout, plus two cable knockouts for flexible wiring. This combination supports a compact footprint with versatile entry points for power and control cables in typical panel builds.
Yes. The TP178 provides AC/MC clamps for secure conduit termination and is designed to be gangable, allowing multiple boxes to be linked for larger circuits. This enables scalable panel configurations without sacrificing access to wiring and terminations, ideal for expanding control systems in evolving facilities.
The TP178 is NEC/CEC compliant and carries Canadian certifications for steel switch boxes. This ensures suitability for ordinary/Non-Hazardous locations and supports regulatory approval workflows in North American manufacturing environments, backed by documented certification references and catalog information.
Best suited for electrical distribution in control panels and machine enclosures within manufacturing, packaging, and automation lines. Its 12.5 cu in capacity, 2-1/2 in depth, and gangable steel construction support compact layouts with scalable expansion, reducing installation time and improving wiring organization in non-hazardous settings.
Plan for efficient wiring by leveraging the side and bottom knockouts and the AC/MC clamps to minimize field adjustments. Use the ears for quick mounting on panels, and consider gangable configurations to reduce inventory while enabling future expansion. The result is faster installs, fewer reworks, and lower total cost of ownership.
