B-LINE 181812 SCGV NK – Frequently Asked Questions

1) Can a NEMA 1 junction box like the B-Line 181812 SCGV NK be used outdoors or in a wash-down area?
No. The 181812 SCGV 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 NEMA 3R or 4 rated enclosure instead. The screw cover and galvanized steel body here are built for dry indoor mechanical rooms, electrical closets, and ceiling spaces.
2) What are the actual box dimensions of the B-Line 181812 SCGV NK junction box?
It measures 18 inches high by 18 inches wide with a 4 inch depth, so it is a square 18x18x4 pull box. That 4 inch depth is what governs your conduit entry and bending space, so check your largest conductor's required bending radius against it before you commit.
3) Does this B-Line junction box come with knockouts already punched?
No. The SCGV NK designation means no knockouts, so the body ships blank and you punch your own conduit entries exactly where the run needs them. That is why electricians pick the NK version for field-routed work. If you want factory knockouts, you need the knockout version of the enclosure rather than the NK.
4) How is the 18x18x4 B-Line screw cover box mounted, and can one person hang it?
It surface mounts through thru holes in the back of the box, so it fastens flat to a wall, backboard, or strut with your own hardware. At 25.3 pounds empty it is a two-hand lift, and the cover uses keyhole slots so you can back the cover screws out part way, drop the cover on, and tighten, which lets one person handle the cover without juggling loose screws. Mounting fasteners are not part of the enclosure.
5) Is this junction box UL listed for a commercial job spec?
The 181812 SCGV NK is built to UL 50, the standard covering enclosures for electrical equipment, and carries a NEMA Type 1 rating. It is made in the US. Those are the two lines a spec reviewer normally wants on an indoor pull box submittal.
6) Screw cover or hinged door enclosure, which should I use for a junction point I rarely open?
A screw cover box like the 181812 SCGV NK is the right call for a pull or splice point you open occasionally, since the cover comes off completely and gives you full access to all four corners of an 18 by 18 opening. Pick a hinged door enclosure instead where you are mounting devices inside and opening it routinely, or where the cover would be awkward to hold overhead. The keyhole slots on this cover are what make the screw type workable on a wall at height.
