B-Line Eaton series Type 1 junction boxes, 30" height, 10" length, 30" width, 1, Screw cover, SCGV NK enclosure, Surface mounted, Medium single door,

No. This is a NEMA Type 1 enclosure, which is indoor-only protection against incidental contact and falling dirt. It offers no rating against rain, hose-down, dust ingress, or corrosive atmospheres, so keep it in dry interior spaces like electrical rooms, mechanical rooms, and finished utility areas. For wet or outdoor locations you need a Type 3R or Type 4 enclosure instead.

It is a 30 x 30 x 10 inch box: 30 inches high, 30 inches wide, and 10 inches deep. That depth gives room for wire bending and gutter space on larger feeder pulls, and the 30 by 30 face is a common size for junction and pull box applications where several conduits land on one box.

No knockouts. The SCGV NK is supplied blank, so the installer drills or punches every conduit entry where the job needs it. Plan on a hole saw or knockout punch set for your conduit sizes and budget the labor. If you want factory openings, you need a knockout version rather than the NK.

Surface mount, using thru holes in the back of the box. There are no external mounting feet, so your fasteners pass through the enclosure interior and into the wall or strut behind it. At 79.7 lb empty, anchor into structure, strut, or blocking rather than drywall alone, and account for the weight of conductors after the pull.

It is a screw cover, not a hinged door, so the cover lifts completely free once the plated screws are out. The cover has keyhole slots, which let you back the screws out part way and lift the cover off without removing them entirely, then hang it back on for re-fastening. On a 30 x 30 panel that keyhole detail is what makes it manageable solo. The whole assembly weighs 79.7 lb, so mount it with help.

Built from 12 gauge galvanized steel, which is heavy wall for a box this size and holds its shape when conduit and conductors load one side. The finish is unfinished galvanized, grey in appearance, so no paint is applied from the factory. If the spec calls for a painted enclosure to match other gear, it has to be field finished or you specify a painted model.

A screw cover box such as the 303010 SCGV NK suits junction and pull box duty, where you open it at rough-in and then rarely again. The cover comes fully off, giving unobstructed access to all four corners for a large pull. If a technician has to open the box routinely for terminations, metering, or controls, a hinged door enclosure is the better choice, since a loose 30 x 30 screw cover has to be set down and re-fastened every time.

Order Eaton B-Line part number 303010 SCGV NK. The number reads directly off the dimensions: 30 inch height, 30 inch width, 10 inch depth, screw cover galvanized, no knockouts. Getting the NK suffix right matters, since the knockout and no-knockout versions are different parts.
