B-LINE 484812 SC NK – Frequently Asked Questions

1) Can the B-Line 484812 SC NK junction box be used outdoors or in a washdown area?
No. The 484812 SC NK is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, dust or liquids. For a wet or outdoor location you need a Type 3R, 4 or 4X enclosure instead. Use this one in dry indoor electrical rooms, mechanical spaces and back-of-house areas.
2) What are the actual box dimensions on the B-Line 484812 screw cover junction box?
It measures 48 inches high, 48 inches wide and 12 inches deep, which is where the 484812 designation comes from. That 12 inch depth matters for wire bending space and for how far the box will stand off a wall once surface mounted, so check your clearance in front of conduit runs and any panel doors swinging nearby.
3) Does this B-Line junction box come with knockouts for conduit?
No knockouts. The 484812 SC NK is a no-knockout box, so every conduit entry has to be field punched or drilled where you want it. That is normally what a contractor wants on a large pull box, since entries get located to suit the raceway layout, but budget the hole saws or a knockout punch set into the install.
4) How is the 48 x 48 x 12 B-Line enclosure mounted, and does it hang on the wall?
It is a surface mount enclosure with thru holes in the back for fastening to the wall or a mounting structure. At 220 lb empty it needs real structural backing, not drywall anchors, and you want two people plus lifting equipment to set it. Unistrut or a welded stand is common for a box this size.
5) Is this B-Line junction box UL listed for a commercial or institutional project spec?
It carries UL 50, the enclosure standard for electrical equipment, alongside the NEMA Type 1 rating. That pairing is the usual spec line for an indoor pull or junction box in commercial and institutional work. It is also US made, which helps where domestic sourcing is a condition of the contract.
6) What gauge steel is the B-Line 484812 SC NK made from?
12 gauge carbon steel, painted ANSI 61 grey. That is a heavy wall for an enclosure and it is why the box weighs 220 lb bare, but it also means the walls stay flat when you field punch conduit entries and the box carries cable weight without deflecting.
7) What does the medium double door style mean on this 48 inch B-Line enclosure?
The 484812 SC NK is built in B-Line's medium double door style, meaning the 48 by 48 inch opening is covered by two panels rather than one oversized sheet. That keeps each removable section manageable and lets you open only half the box to work one side of the wiring.
