No. The 30244 SC NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, hose-down, dust, or corrosive atmospheres. Keep it in dry, conditioned indoor spaces like electrical rooms, mechanical rooms, or above-ceiling runs. For wet or outdoor locations you need a Type 3R or Type 4 enclosure instead.

No knockouts. The SC NK designation is a no-knockout box, so every conduit entry gets punched or hole-sawed in the field where you want it. That is an advantage on a custom pull box layout, but it means you need a knockout punch set on the truck. The body is 14 gauge carbon steel, so size your punch and draw stud accordingly.

Surface mount, using thru holes in the back of the box. There is no flush or recessed trim kit involved, and no mounting feet to install. Because the fasteners pass through the enclosure wall, pick hardware rated for the 41.1 lb box weight plus whatever conductors and devices land inside, and seal nothing, since a Type 1 box is not intended to be sealed.

Order it as Eaton B-Line 30244 SC NK. The number reads as the dimensions first, 30 inch height by 24 inch width by 4 inch depth, then SC for screw cover and NK for no knockouts. Quote all of it, since the same size exists in knockout and hinged versions.

The finish is painted ANSI 61 grey, the standard light grey used across most commercial switchgear and enclosure lines, so it reads as a match next to typical panel and gear finishes. Over carbon steel, that paint is the only corrosion protection, which is another reason to keep it indoors.
