B-LINE 24186 SC NK – Frequently Asked Questions

1) Can a NEMA 1 screw cover junction box like the B-Line 24186 SC NK be used outdoors or in a washdown area?
No. The 24186 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 rain, hose-down, dust ingress, or corrosive atmospheres. For wet or outdoor locations you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions on the B-Line 24186 SC NK junction box?
24 inches high, 18 inches wide, and 6 inches deep. That 6 inch depth is what usually decides the job, since it sets how much room you have for conduit bodies, gutter fill, and wire bending space behind the cover.
3) Does this B-Line junction box come with conduit knockouts already punched?
No. The NK in 24186 SC NK means no knockouts, so the box ships blank on all sides and you punch your own openings where the conduit runs actually land. If you want factory knockouts, order the knockout version of the same size rather than this one.
4) Is this box meant to be surface mounted on a wall, or flush recessed?
Surface mount. The 24186 SC NK has thru holes in the back pan for bolting or lagging flat to a wall, strut, or backboard. It is not a flush or recessed enclosure, and there is no trim ring for drywall cut-in.
5) How does the cover attach, and can one person handle it during install?
The cover is a screw cover with keyhole slots and plated screws. The keyholes let you back the screws out partway and lift the cover off without fully removing them, which matters when you are working off a ladder alone. Total box weight is 25.6 lb.
6) What gauge steel is the B-Line 24186 SC NK, and will the finish match our other electrical enclosures?
Body is carbon steel at 16 gauge, painted ANSI 61 grey. ANSI 61 is the standard grey used across most industrial enclosures and panelboards, so it lines up with the rest of a typical electrical room without repainting.
7) Is this junction box UL listed for a commercial or institutional spec job?
It is built to UL 50, the standard covering enclosures for electrical equipment, and it is US made. That plus the NEMA 1 rating is what most indoor commercial pull box and gutter specs call for.
8) Is a screw cover box like this the right choice, or should I use a hinged door enclosure?
A screw cover box such as the 24186 SC NK suits pull boxes, splice points, and wireways you rarely open, since the cover is fastened with plated screws through keyhole slots. If the enclosure will be opened regularly for servicing or houses devices someone needs frequent access to, a hinged door enclosure is the better pick.
