B-LINE 863 SC NK – Frequently Asked Questions
1) Can the Eaton B-Line 863 SC NK junction box be used outdoors or in a washdown area?
No. The 863 SC NK carries a NEMA Type 1 rating, which is indoor use only, for general purpose protection against incidental dust and contact with the enclosed parts. It offers no protection against rain, hose-down, or corrosive atmospheres. For a wet or outdoor location you need a NEMA 3R or 4 enclosure instead.
2) What are the actual box dimensions on the B-Line 863 screw cover junction box?
It measures 8 inches height, 6 inches width, and 3 inches length/depth. The 3 inch depth is the usable interior depth you have for splices and connectors, so plan conduit entries and wire bending space around that.
3) Does the B-Line 863 SC NK come with knockouts for conduit?
No knockouts. The NK in the model designation means no knockout, so the box ships blank and you drill or punch your own openings exactly where the conduit lands. If you want factory knockouts, order a knockout version rather than the NK.
4) How does this B-Line screw cover box mount to a wall?
Surface mounted, using thru holes in the back of the box, so it fastens flat to a wall, panel, or strut with your own hardware. The cover itself has keyhole slots, which lets you back the plated cover screws out partway and lift the cover off without fully removing them.
5) What gauge steel is the B-Line 863 box and will it hold up in a mechanical room?
The body is carbon steel at 16 gauge with a painted finish in ANSI 61 grey, which is the standard commercial enclosure finish. That is heavy enough for typical indoor plant, mechanical room, and back-of-house service work. In a corrosive or damp environment, move up to a stainless or non-metallic enclosure.
6) Is the cover hinged or does it screw on?
Screw cover. It is a small single door style enclosure with plated cover screws and keyhole slots, not a hinged door, so the cover comes off completely for access. If you need frequent access without handling a loose cover, look at a hinged cover enclosure instead.
7) Will the 863 SC NK match the grey enclosures already installed in my building?
The finish is ANSI 61 grey paint, the same standard grey used across most commercial panel and enclosure lines, so it blends with existing gear in a typical electrical room or corridor run.
8) How much does the B-Line 863 SC NK weigh and is it a one-hand install overhead?
It weighs 3.3 pounds, light enough to hold up and start fasteners single-handed on an overhead or high wall mount, though the thru holes in the back mean you will want the layout marked first.
9) Is the B-Line 863 junction box made in the USA?
Country of origin is the US, which matters on public and institutional jobs carrying domestic sourcing requirements.
