B-LINE 30246 SC NK – Frequently Asked Questions

1) Can a NEMA 1 screw cover junction box like the B-Line 30246 SC NK be used outdoors or in a washdown area?
No. The 30246 SC NK carries a NEMA Type 1 rating, which is indoor use only, for protection against incidental contact and falling dirt. It gives no protection against water, washdown, dust ingress or corrosive conditions. For an outdoor or wet location you need a NEMA 3R or 4 enclosure instead.
2) What are the actual box dimensions of the B-Line 30246 SC NK junction box?
It measures 30 inches high by 24 inches wide with a 6 inch depth, so it takes a wall space of 30 x 24 and stands 6 inches off the surface once mounted. Plan gutter space and conduit entries around that 6 inch depth, which is the tight dimension when you are pulling large conductors.
3) Does this Eaton B-Line junction box come with knockouts, or do I have to punch my own conduit openings?
No knockouts. The 30246 SC NK is a blank box, so every conduit entry gets punched in the field to suit your run. That is the point of the NK version: you place the holes where the job needs them instead of working around factory locations.
4) How does the cover come off on the B-Line 30246 SC NK, and can one person handle it?
It is a screw cover, not a hinged door, so the cover lifts clear once the plated screws are backed out. Keyhole slots on the cover let you loosen the screws and slide the cover off without fully removing every screw, which helps when you are working alone. The whole enclosure weighs 45.8 lb, so mount it before you start filling it.
5) How is this junction box mounted to the wall?
Surface mount, using thru holes in the back of the box. That means fasteners pass through the enclosure wall into your structure, so pick anchors rated for the 45.8 lb empty weight plus whatever wire and devices go inside. It is not a flush or recessed box.
6) What gauge steel is the B-Line 30246 SC NK made from?
Carbon steel at 14 gauge, painted in ANSI 61 grey. The 14 gauge body is heavier than the light-gauge boxes you see on residential work, which matters if you are punching multiple large conduit entries or hanging terminal blocks off the back pan.
7) Is this B-Line junction box UL listed for a commercial spec job?
Yes, it is built to UL 50, the standard covering enclosures for electrical equipment. It is also made in the US, which helps if the project carries domestic sourcing requirements.
8) Will the grey finish on this box match the other B-Line enclosures already on my wall?
The 30246 SC NK is finished in ANSI 61 grey, the standard industrial enclosure grey used across most B-Line and comparable steel enclosure lines, so it lines up visually with existing panels and pull boxes in that color. It ships painted, not bare or galvanized.
