B-LINE 24188 SC NK – Frequently Asked Questions

1) Can the Eaton B-Line 24188 SC NK junction box be used outdoors or in a washdown area?
No. The 24188 SC NK is a NEMA Type 1 enclosure, which is for indoor, dry locations only. It offers no protection against rain, hose-down, dust ingress or corrosive atmospheres. For an outdoor pull box or a wet mechanical room you need a Type 3R or Type 4 enclosure instead.
2) What are the box dimensions on the B-Line 24188 junction box, and does the model number tell me the size?
The 24188 measures 24 inches high, 18 inches wide and 8 inches deep, and yes, the first digits of the catalog number read out as those dimensions: 24 x 18 x 8. Plan your wall space and conduit entries around the 8 inch depth, since that is what governs bending space for conductors landing in the box.
3) Does this B-Line screw cover box come with knockouts already punched?
No knockouts. The SC NK suffix means screw cover, no knockout, so the box ships blank and you punch your own conduit entries wherever the run lands. That is the usual choice when you are feeding multiple conduit sizes or want the entries placed to suit the job rather than the factory pattern. If you would rather not punch holes in the field, order a knockout version.
4) How does the 24188 SC NK mount to the wall, and do I need to drill through the back?
It is a surface mount box with thru holes already provided in the back for fasteners, so you anchor it straight to the wall or backboard without drilling the enclosure. Mounting anchors or screws are selected to suit your substrate. The cover also has keyhole slots, so you can back the cover screws out part way and lift the cover off instead of fully removing every screw.
5) What gauge steel is this junction box, and is it painted or bare?
Carbon steel at 16 gauge, painted in ANSI 61 grey. The cover screws are plated. ANSI 61 grey is the standard gear grey, so it matches typical panelboards and control enclosures in a plant or electrical room.
6) Should I use a screw cover box or a hinged door enclosure for a pull point?
A screw cover box like the 24188 SC NK is meant for a junction or pull point you rarely open, where the cover comes off only during pulls or troubleshooting. The keyhole slots in the cover make that removal quicker. If someone will be opening the box routinely, for controls or terminations you service often, a hinged door enclosure is the better call because the cover stays captive on the box.
7) Is the Eaton B-Line 24188 SC NK made in the USA?
Country of origin is the United States. That matters on public work and institutional jobs carrying domestic sourcing requirements, so it is worth noting on the submittal.
