B-LINE 15156 SC NK – Frequently Asked Questions

1) Can a NEMA 1 screw cover junction box like the B-Line 15156 SC NK be used outdoors or in a washdown area?
No. The 15156 SC NK carries a NEMA Type 1 rating, which is indoor use only and protects against incidental contact and falling dirt. It offers no protection against water, oil, or dust, so anywhere exposed to rain, hosedown, or high humidity needs a gasketed Type 3R, 4, or 12 enclosure instead.
2) What are the box dimensions on the B-Line 15156 junction box?
It measures 15 inches high, 15 inches wide, and 6 inches deep. The 6 inch depth is the number that usually decides it, since that is what gives you bending room for larger conductors and space for terminal blocks or small din rail behind the cover.
3) Does this B-Line enclosure come with conduit knockouts already punched?
No knockouts. The NK in 15156 SC NK means no knockout, so the box ships blank and you punch your own conduit entries where the run needs them. Plan on a step bit or knockout punch set on site. If you would rather have factory entries, order a knockout version instead.
4) How does the 15156 SC NK mount to a wall, and is the hardware inside the wiring space?
It is surface mounted through mounting holes in the back of the box, so the fasteners pass through the enclosure interior. Use that when the wall is accessible and you do not need a flush trim. The cover also has keyhole slots, which lets you hang the cover on partially driven screws while you start the rest, a real help on a 13.8 pound steel box worked overhead.
5) Will this B-Line box match the other grey enclosures already in my electrical room?
The finish is painted ANSI 61 grey, which is the standard light grey used across most industrial panelboards, control enclosures, and junction boxes. It will read as a match next to other ANSI 61 gear.
6) How heavy gauge is the steel on this B-Line junction box?
The body is 16 gauge carbon steel. That is the usual weight for a box this size, stiff enough that the walls will not oil can when you punch conduit entries or land heavy conduit on the side.
7) Screw cover or hinged door enclosure, which should I use for a pull box?
A screw cover box like the 15156 SC NK is the right call for a pull or splice point you rarely open, since the cover comes off completely and gives you full access to all four walls for pulling. Where a tech needs to get in regularly, a hinged door version is less hassle because the cover stays captive. The screw cover here uses plated screws, so the threads resist corrosion through repeated removals.
8) What exact part number do I order for the 15 x 15 x 6 B-Line screw cover box with no knockouts?
Order Eaton B-Line 15156 SC NK. The number reads off the dimensions: 15 high, 15 wide, 6 deep, SC for screw cover, NK for no knockout.
