Feature → Business Impact → Application: Steel construction and 18 cubic inch capacity deliver durable, scalable wiring space that supports expanding control systems and reduces enclosure replacements, lowering lifecycle costs. This enables maintenance teams to wire cleanly and document layouts for future modifications, especially in evolving automation projects where panel density increases. Application: control panels in manufacturing lines and process equipment that require a robust, gangable steel switch box. Feature → Business Impact → Application: Gangable design enables quick expansion by adjoining boxes, increasing total capacity without needing new housings, which accelerates project timelines and minimizes downtime. Application: modular panel builds in multi-sentence automation or retrofit projects where space is at a premium. Feature → Business Impact → Application: (2) end knockouts at 3/4 in and (1) bottom knockout at 1/2 in provide flexible routing for 1/2 in to 3/4 in conduits, reducing wiring complexity and installation errors. Application: field installs where wiring paths must be adjusted to fit existing conduit layouts. Feature → Business Impact → Application: Conduit (no clamps) simplifies mounting and reduces accessory costs, saving installation time and avoiding extra hardware. Application: new installations in space-constrained control panels. Feature → Business Impact → Application: Product dimensions (3 in depth, 3.5 in height, 2 in width) and weight (0.73 lb) deliver a compact, lightweight enclosure that minimizes panel footprint and handling effort during installation. Application: retrofits and space-limited electrical rooms. Feature → Business Impact → Application: NEC/CEC compliance and ordinary/non-hazardous location suitability provide regulatory alignment, protecting projects from rework and speeding procurement. Application: industrial facilities operating under standard location classifications.
