B-LINE 362412 SC NK – Frequently Asked Questions
1) Can a NEMA 1 screw cover junction box like the B-Line 362412 SC NK be used outdoors or in a washdown area?
No. The 362412 SC NK carries a NEMA Type 1 rating, which is indoor use only and offers no protection against rain, dust ingress, or hosedown. For outdoor or wet locations you need a Type 3R, 4, or 4X enclosure instead. Keep this one in dry indoor electrical rooms, mechanical spaces, and above-ceiling pull-box applications.
2) What are the actual box dimensions of the B-Line 362412 SC NK junction box?
36 inches high, 24 inches wide, and 12 inches deep. That 12 inch depth is what gives you room for bending radius on larger conductors and for stacking splices, so it works as a pull box on heavy feeder runs, not just a small tap point. Verify the depth against your conduit entry positions before you lay out the wall.
3) Does the B-Line 362412 junction box come with knockouts, or do I have to drill my own conduit entries?
It is the NK (no knockout) version, so the walls come blank. You drill or punch every conduit entry yourself wherever the run lands. That is the reason to spec NK: full freedom on hole placement. If you want factory holes so the crew is not punching 14 gauge steel on site, order a knockout version instead.
4) How is this B-Line enclosure mounted to the wall, and does it need a separate mounting kit?
It is a surface mount box with thru holes in the back pan, so it bolts straight to the wall or to strut through those holes with hardware sized to your substrate. No panel or flush trim kit is involved. At 68.6 lb empty, plan anchors into studs, masonry, or unistrut rather than drywall alone, and get two people on the lift.
5) What gauge steel is the B-Line 362412 enclosure, and what finish does it come in?
Carbon steel at 14 gauge, painted ANSI 61 grey. That is the standard grey used across most commercial switchgear and panel lineups, so it blends with existing gear in an electrical room. Because it is painted carbon steel, keep it away from corrosive or damp environments where you would want stainless or a coated Type 4X box.
6) Is the B-Line 362412 SC NK junction box UL listed for an inspected commercial job?
It is built to UL 50, the standard covering enclosures for electrical equipment. Combined with the Type 1 rating, that is what an inspector looks for on an indoor pull or junction box. The unit is made in the US.
7) What part number do I give my distributor for the 36 x 24 x 12 B-Line screw cover box?
Order Eaton B-Line 362412 SC NK. The number reads as the dimensions first (36 high, 24 wide, 12 deep), then SC for screw cover and NK for no knockouts. If your spec calls for factory conduit openings, the NK suffix is the part to change.
