B-LINE 18184 SCGV NK – Frequently Asked Questions
1) Can the B-Line 18184 SCGV NK junction box be used outdoors or in a wash-down area?
No. The 18184 SCGV NK is a NEMA Type 1 enclosure, which is indoor-only protection against falling dirt and incidental contact. It is not rated for rain, sprayed water, dust-tight service or corrosive washdown. For outdoor or damp locations you need a Type 3R, 4 or 4X enclosure instead.
2) What are the box dimensions on the B-Line 18184 SCGV NK?
It measures 18 inches high by 18 inches wide with a 4 inch depth, so it's a square medium single-door style body with a shallow back box. That 4 inch depth is the number to check against your conduit bodies and wire bend radius before you commit, since a 4 inch deep box fills quickly on larger conductors.
3) Does the 18184 SCGV NK come with conduit knockouts already punched?
No. The NK in the model designation means no knockouts, so the box ships blank and you punch or drill your own entries where the run needs them. Plan on a knockout punch set or hole saw on site. If you want factory entries, order a knockout version of the same size instead.
4) Will this enclosure satisfy a spec calling for a UL listed Type 1 junction box made in the USA?
Yes on both counts. The Eaton B-Line 18184 SCGV NK carries UL 50 certification, the standard for enclosures for electrical equipment, and is a NEMA Type 1. Country of origin is the US, which matters on government, education and other domestic-preference procurement.
5) How does the cover attach on this B-Line junction box, and can one person hang it?
The cover is a screw cover with plated screws, and it has keyhole slots so you can hang it on partially driven screws and then tighten down, which makes a one-man install on an 18 x 18 cover practical. Screw covers are removable for access but are not hinged, so allow clear space in front to lift the cover off entirely.
6) Is this junction box painted, and will it corrode in a mechanical room?
There is no paint on it. The body is galvanized steel with an unfinished grey surface, so the zinc coating is doing the corrosion work rather than a finish coat. That suits mechanical rooms, electrical rooms and plenum-adjacent indoor spaces. In a chemically aggressive or wet environment, move to a stainless or non-metallic enclosure.
7) Is the 18184 SCGV NK a pull box or does it hold equipment?
Treat it as a junction and pull box. It is an empty screw-cover enclosure with no knockouts, no interior panel and no din rail, so it is used for splices, pulls and taps in indoor conduit runs. If you need to mount a controller or breaker panel behind a door, specify an enclosure supplied with a back panel instead.
8) What gauge steel is the 18184 SCGV NK, and will it stay flat on a long wall run?
Walls are 16 gauge galvanized steel. On an 18 x 18 box that's heavy enough to resist oil-canning and to hold threaded fittings and punched entries without reinforcement, which is why 16 gauge is the usual commercial choice over lighter residential boxes.
