B-LINE 24128 SC – Frequently Asked Questions

1) Can a B-Line 24128 SC junction box be used outdoors or in a washdown area?
No. The B-Line Eaton 24128 SC is a NEMA Type 1 enclosure, which is indoor use only and offers no protection against rain, dust, or hosedown. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead. Use the 24128 SC for dry indoor electrical rooms, mechanical spaces, and interior wall runs.
2) Does this B-Line enclosure come with knockouts or do I have to punch my own?
Knockouts are already provided: 9 on the sides, 5 on the top and 5 on the bottom. That gives you conduit entry on four faces without pulling out a punch set, though you can still hole-saw or punch the blank areas if your run doesn't line up.
3) Is this Eaton B-Line junction box UL listed for a commercial job spec?
It carries UL 50, the standard for enclosures for electrical equipment, and is rated NEMA Type 1. Country of origin is the US, which matters on public work with domestic sourcing language in the spec.
4) What are the actual box dimensions on the B-Line 24128 SC screw cover enclosure?
It measures 24 inches high, 12 inches wide and 8 inches deep, so plan on a 24 x 12 footprint on the wall with 8 inches of projection off the surface. That depth gives real room for wire bending space and splices on larger conductor runs. Shipping weight is 19.1 lb.
5) How does the 24128 SC mount to a wall, and is mounting hardware part of the box?
It is a surface-mount enclosure with thru holes in the back for fastening straight to the wall or to strut. Fasteners are chosen to suit the substrate, so pick anchors rated for the 19.1 lb box plus whatever wiring and devices go inside. The cover also has keyhole slots, which lets you back off the screws and lift the cover away instead of fully removing every screw.
6) Is the cover on this B-Line junction box hinged or a screw-on lid?
Screw cover, not hinged. It fastens with plated screws and the cover has keyhole slots so it can be lifted off once the screws are loosened. If you need to open the box repeatedly for service or a device is mounted inside, a hinged-door enclosure is the better choice; a screw cover suits pull points and splice boxes that stay closed.
7) What part number do I order for the 24 x 12 x 8 B-Line screw cover box?
The manufacturer part number is 24128 SC from Eaton's B-Line series. The digits track the size: 24 inch height, 12 inch width, 8 inch depth, with SC for screw cover.
8) What gauge steel is the B-Line 24128 SC, and what's the finish?
Body is carbon steel at 16 gauge, painted in ANSI 61 grey. That is the standard grey used across most commercial electrical gear, so it blends with panelboards and wireway in the same room without repainting.
