B-LINE 181210 SC NK – Frequently Asked Questions
1) Can the B-Line 181210 SC NK junction box be installed outdoors or in a washdown area?
No. The 181210 SC NK is a NEMA Type 1 enclosure, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against rain, hose-down, or dust ingress. 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 181210 junction box?
It measures 18 inches high, 12 inches wide and 10 inches deep, which is where the 181210 designation comes from. That 10 inch depth is generous for a box this size and gives room for gutter wiring, splices, or terminal blocks rather than just a pull point.
3) Does this Eaton B-Line junction box come with knockouts?
No. The NK in 181210 SC NK means no knockouts, so the box ships with blank walls and you punch your own conduit entries wherever the run needs them. Budget for a knockout punch or hole saw and the appropriate connectors. If you want factory knockouts, order the knockout version of the same size rather than the NK.
4) How is the B-Line 181210 mounted to a wall?
Surface mount, using thru holes in the back of the enclosure. You anchor straight to the wall or to Unistrut behind it. At 17.4 pounds empty, and heavier once conduit and conductors land on it, use anchors rated for the substrate rather than drywall toggles alone.
5) How does the cover attach, and can one person get it off while on a ladder?
The cover is screw-attached with plated screws, and it has keyhole slots so you can back the screws out part way and lift the cover off without fully removing them. That is the detail that makes a 18 x 12 x 10 box manageable single-handed on a ladder. It is not a hinged door, so plan for somewhere to set the cover down.
6) What is this junction box made of, and will the finish match the other gear in my electrical room?
Carbon steel, 16 gauge, painted ANSI 61 grey. ANSI 61 is the standard grey used across most industrial panelboards and control enclosures, so it will read as a match next to typical switchgear and control cabinets in a plant or electrical room.
7) Is the B-Line 181210 SC NK a UL listed enclosure for a spec job?
It is built to UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. Those are the two lines a submittal usually needs alongside the Type 1 rating and the 16 gauge carbon steel construction.
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 181210 SC NK suits pull points, splice boxes and gutters you open rarely, and the screw-down cover discourages casual access. If you are mounting devices you will service regularly, or need to open the box repeatedly while working live, a hinged door enclosure is the better call. This one is a medium single door style, surface mounted, screw fastened.
