FAQs
The TP404RED is designed for ordinary/non-hazardous locations with NEC/CEC compliance, UL certification, and a welded steel construction. For installation, plan for the eight 1/2 in and four 1/2 in side knockouts plus bottom knockouts to route conductors, using conduit entries without clamps. Ensure the enclosure is mounted securely to minimize vibration and protect internal components from dust and moisture exposure typical in general manufacturing settings.
With 22 cubic inches of internal volume, the TP404RED accommodates a practical amount of wiring and small devices, reducing the need for splices and multiple smaller boxes. This streamlines assembly, lowers labor time, and improves airflow around components. In tight control panels, the space efficiency helps fit relays, terminations, and basic wiring harnesses without crowding.
Yes. The TP404RED carries NEC/CEC standards and UL certification, and it is classified for Ordinary/Non-Hazardous Locations. This makes it appropriate for typical factory floors, machine enclosures, and control panels where standard electrical safety code adherence is essential. For compliance, avoid location classifications beyond Ordinary/Non-Hazardous and verify panel ratings match your process requirements.
The box is engineered for conduit (no clamps) with a set of side and bottom knockouts (8× 1/2 in and 4× 1/2 in side knockouts, plus 1× 3/4 in E; bottom: 2× 1/2 in, 2× 1/2 in, 1× 3/4 in E). This provides flexible routing options and reduces field modification time. Use appropriate conduit fittings and ensure knockout openings align with your wiring plan for a sealed, code-compliant installation.
The welded steel construction and 22 cu in capacity contribute to a durable enclosure with low maintenance needs, reducing rework and replacement costs over time. Its standard 4-inch footprint and compatibility with common conduit practices simplify replacements or upgrades in aging systems. This translates to predictable maintenance budgeting and steadier project timelines.
