B-LINE 48366 SC NK – Frequently Asked Questions

1) Can a NEMA 1 screw cover junction box like the B-Line 48366 SC NK be installed outdoors or in a washdown area?
No. The 48366 SC NK carries a NEMA Type 1 rating, which is indoor use only and offers no protection against water, dust, or corrosive liquids. It is for dry indoor locations such as electrical rooms and mechanical spaces. For wet or outdoor work you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions on the B-Line 48366 SC NK junction box?
48 inches high, 66 inches long, and 3 inches deep. That 3 inch depth is shallow, so plan your conductor bending space and gutter fill around it before pulling; a deep box is a different part number.
3) Does this B-Line junction box come with conduit knockouts already punched?
No knockouts. The 48366 SC NK is supplied blank, so every conduit entry gets field punched or drilled where you want it. The only factory holes are thru holes for mounting.
4) How is this 48 x 66 inch B-Line enclosure supported on the wall?
Surface mounting through factory thru holes in the back of the box. At 129.2 lb empty, anchor into studs, strut, or masonry rated for the load rather than drywall anchors. It is not a flush or recessed box.
5) What gauge steel is the B-Line 48366 junction box, and is it painted?
12 gauge carbon steel, finished in painted ANSI 61 grey. Twelve gauge is heavy wall for a pull box this size and holds its shape when you are hanging terminal blocks or wireway off the back pan.
6) Is this B-Line enclosure UL listed for a spec job?
It is built to UL 50, the standard for enclosures for electrical equipment, and carries a NEMA Type 1 rating. Country of origin is the US, which matters if your project carries domestic sourcing requirements.
