B-LINE 242412 SC NK – Frequently Asked Questions

1) Can a NEMA 1 junction box like the B-Line 242412 SC NK be installed outdoors or in a washdown area?
No. The 242412 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact with the enclosed equipment and falling dirt. It offers no protection against water, rain, hosedown or corrosive atmospheres. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead.
2) What are the actual box dimensions on the B-Line 242412 junction box?
24 inches high, 24 inches wide, and 12 inches deep. That 12 inch depth is what gives you room for wire bending space and gutter taps behind the cover, and it is the number to check against your available wall clearance before you set the box.
3) Does this B-Line screw cover box come with knockouts, or do I have to punch my own conduit openings?
No knockouts. The SC NK box ships blank, so every conduit entry is field punched wherever your raceway lands. Plan on a knockout punch set for the trade sizes you are running. If you want factory knockouts, you need a different B-Line box configuration.
4) How does this junction box mount to the wall?
Surface mounting, using thru holes in the back of the enclosure. You fasten directly through the box into the wall or into strut, so your anchors have to suit the substrate and carry a box that weighs 43.9 pounds empty, before conductors. It is not a flush or recessed box.
5) Is a screw cover box the right choice, or should I use a hinged door enclosure?
A screw cover box like the 242412 SC NK is for pull points, splices and terminations you rarely open. The cover comes off entirely with plated screws, and keyhole slots on the cover let you hang it on the screws while you start them, which is what makes a 24 x 24 cover manageable overhead on your own. If the box houses equipment you need to access routinely, a hinged door enclosure is the better pick.
6) What gauge steel is the B-Line 242412 junction box, and what is the finish?
14 gauge carbon steel, painted ANSI 61 grey. That is the standard commercial enclosure gauge and grey, so it matches typical panel and gutter work in the same room. Painted carbon steel suits dry indoor areas; it is not a stainless or corrosion service box.
7) What is the exact part number to order this B-Line 24 x 24 x 12 screw cover box?
Eaton B-Line part number 242412 SC NK. The number reads as the dimensions first (24 high, 24 wide, 12 deep), then SC for screw cover and NK for no knockouts.
