B-LINE 16166 SC NK – Frequently Asked Questions

1) Can a NEMA 1 junction box like the B-Line 16166 SC NK be used outdoors or in a washdown area?
No. The 16166 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It offers no protection against water, oil, or dust ingress, so keep it out of exterior locations, washdown areas, and wet mechanical rooms. For those spots you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions of the B-Line 16166 SC NK junction box?
It measures 16 inches high, 12 inches wide, and 6 inches deep, which is where the 16-16-6 in the model number comes from. The 6 inch depth is what matters most for conduit bodies and wire bending room, so check that against your largest conductor before you commit.
3) Does this B-Line screw cover enclosure come with knockouts, or do I have to drill my own conduit entries?
No knockouts. The 16166 SC NK is a blank NK (no knockout) box, so every conduit entry gets punched or drilled on site wherever your raceway lands. That is the advantage of the NK version for a contractor routing multiple conduits, and the reason to pick a knockout version instead if you want factory-located hub openings.
4) How does this junction box mount to the wall, and are mounting holes already provided?
It is a surface mount enclosure with thru holes in the back for fastening directly to a wall or structure. Thru holes mean the fasteners pass through the enclosure interior, so the back pan is penetrated, fine for a Type 1 indoor box. Wall anchors or machine screws are not supplied, so pick fasteners to suit your substrate and the 15.2 lb empty weight plus your conductors.
5) Is the cover on the 16166 SC NK hinged or screw-on, and how easy is it to get off for service?
Screw cover, not hinged. Plated screws hold it on, and the cover has keyhole slots so once you back the screws out part way you can lift and slide the cover off rather than juggling loose hardware in a ceiling space. If you are opening the box often for terminations or metering, a hinged door enclosure is the friendlier choice; for a junction or pull point that gets closed up and left, the screw cover is standard.
6) What gauge steel is this Eaton B-Line junction box, and what is the finish?
The body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard grey that matches most industrial panels and gutter. Steel construction means it should not go in a corrosive or damp environment without protection, and field-drilled conduit openings will expose bare metal that is worth touching up.
7) Is this junction box UL listed for a commercial or institutional installation?
Yes. The 16166 SC NK is built to UL 50, the standard covering enclosures for electrical equipment, which is what an inspector or facilities spec typically calls for on an indoor Type 1 box. It is made in the US.
8) How much does this enclosure weigh for overhead or ceiling mounting?
15.2 lb empty. Add your conductors, splices, and any terminal strips on top of that when you size unistrut, anchors, or overhead support, and remember the 16 gauge steel body gives you no flex to hide a poorly anchored fastener.
