B-LINE 12124 SC NK – Frequently Asked Questions

1) Can the Eaton B-Line 12124 SC NK junction box be used outdoors or in a washdown area?
No. The 12124 SC NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, hose-down, dust, or corrosive conditions. It's for dry indoor locations such as mechanical rooms, electrical closets, and back-of-house walls. For any outdoor or wet location you need a NEMA 3R, 4, or 4X box instead.
2) What are the actual box dimensions of the B-Line 12124 junction box?
The box measures 12 inches high, 12 inches wide, and 4 inches deep. That 4 inch depth is what usually decides the job, it gives room for splices and wire bending space but it is not a deep gutter box. It weighs 8.4 lb, so a single person can hang it.
3) Does the B-Line 12124 SC NK come with knockouts for conduit?
No knockouts. The NK in the model designation means no knockout, so the box ships blank and you punch or drill conduit entries exactly where your run lands. Plan on a knockout punch set for the installation. If you want factory conduit openings, order a knockout version of the same size instead.
4) How is this B-Line junction box mounted to the wall?
Surface mount, through thru holes in the back of the box. You fasten it flat to the wall or to unistrut with your own hardware, screws and anchors are not part of the box. It is not a flush or recessed enclosure, so the full 4 inch depth sits proud of the finished wall.
5) How does the cover come off on a B-Line screw cover junction box?
It's a screw cover, not a hinged door. The cover is secured with plated screws and has keyhole slots, so once the screws are backed off part way you can lift and slide the cover free without fully removing every screw. That makes a one-person pull-off practical on a 12 x 12 cover. If you need frequent access with the cover staying attached, a hinged-cover enclosure is the better choice.
6) What gauge steel is the B-Line 12124 junction box, and will it rust indoors?
Carbon steel at 16 gauge, painted in ANSI 61 grey. That's a standard commercial-grade wall thickness for a box this size and it holds shape when you punch conduit entries. The paint is a finish coat for indoor service only, in damp or corrosive areas the carbon steel will corrode and you want a stainless or non-metallic enclosure instead.
7) Will this match the grey enclosures already installed in my building?
The finish is ANSI 61 grey, the standard light grey used across most commercial electrical enclosures and panelboards, so it lines up visually with existing gear in a typical electrical room. It is a painted carbon steel finish.
8) Is the B-Line 12124 SC NK made in the USA?
Yes, country of origin is the United States. That matters on public and institutional work where domestic sourcing is written into the spec. The orderable part number is 12124 SC NK.
