B-LINE 30248 SC NK – Frequently Asked Questions

1) Can a NEMA 1 screw cover junction box like the B-Line 30248 SC NK be used outdoors or in a washdown area?
No. The 30248 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against water, rain, hose-down, dust, or oil. For outdoor or wet locations you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions of the B-Line 30248 SC NK enclosure?
30 inches high, 24 inches wide, and 8 inches deep. That 8 inch depth is what gives you room for wire bending and gutter space behind a screw cover, so check your wall clearance before ordering since it is surface mounted and projects the full 8 inches off the wall.
3) Does this B-Line junction box come with knockouts, or do I have to punch my own conduit holes?
It ships with no knockouts. The 30248 SC NK is a blank-side box, so you punch or drill every conduit entry where you want it. That is an advantage on a custom layout but means you need a hole punch set on site. If you want factory knockouts, order a KO version of the same size instead.
4) How is this B-Line box mounted to the wall?
Surface mount through the back, using thru holes in the rear panel. There are no external mounting feet or flanges in that arrangement, so your fasteners pass through the inside of the box. At 50.2 lb empty, anchor into studs, strut, or masonry rather than drywall alone.
5) How does the cover attach on a screw cover junction box, and can one person hang it?
The cover is a screw-on type fastened with plated screws, and it has keyhole slots so you can hook it onto the screws and let it hang while you start the rest. That is the detail that makes a 30 x 24 cover manageable solo. Note the whole assembly weighs 50.2 lb, so mounting the body itself is a two-person lift in most cases.
6) What gauge steel is this enclosure and what is the finish?
Carbon steel at 14 gauge, painted ANSI 61 grey. Fourteen gauge is a heavy-wall body for a box this size and resists oil-canning on the 30 x 24 face. ANSI 61 grey is the standard industrial gear grey, so it matches switchgear, panelboards, and control cabinets already in most plant rooms.
7) What is the exact part number to order this 30 x 24 x 8 B-Line screw cover box?
Order Eaton B-Line part number 30248 SC NK. The number reads off the dimensions: 30 inch height, 24 inch width, 8 inch depth, SC for screw cover, NK for no knockouts. Confirm the NK suffix if you want the blank version, since the same size is also built with knockouts.
