B-LINE 24186 HC NK – Frequently Asked Questions

1) Can the Eaton B-Line 24186 HC NK junction box be used outdoors or in a washdown area?
No. The 24186 HC NK is a NEMA Type 1 enclosure, which is for indoor use only, protecting against incidental contact and falling dirt. It has no rating against water, oil, dust ingress, or corrosion, so keep it out of exterior walls, wet locations, and washdown areas. For those you need a Type 3R, 4, or 4X enclosure instead.
2) What are the actual box dimensions on the B-Line 24186 HC NK enclosure?
It measures 24 inches high, 18 inches wide, and 6 inches deep. That 6 inch depth is the number to check first if you are stacking terminal blocks or need bending room for large conductors behind the door.
3) Does this B-Line junction box come with knockouts, or do I have to punch my own conduit entries?
No knockouts. The NK in 24186 HC NK means the box ships blank on all sides, so you punch or drill your own conduit openings exactly where the run lands. That is normally what you want on a custom pull or terminal box, but budget the hole saw or knockout punch work into the install.
4) How does the 24186 HC NK mount to the wall, and are mounting holes provided?
It is a surface mount enclosure with thru holes in the back panel area for fastening straight to the wall or to strut. The fasteners themselves are not part of the box, so supply anchors or bolts suited to your substrate. At 23.2 lb empty, plus wire and devices, a drywall-only anchor is not enough; hit studs, strut, or masonry anchors.
5) Is the cover hinged or does it lift off?
Both, in effect. The 24186 HC NK has a hinged single door for routine access, and the cover is removable when you need the opening clear to pull wire or set a back panel. A recessed pull ring and friction dimple hold it shut without separate latching hardware.
6) What gauge steel is this B-Line enclosure, and what is the finish?
16 gauge carbon steel, painted ANSI 61 gray. That is the standard industrial gray that matches most switchgear and control panels already on the wall, so it blends into an existing lineup. Painted steel is fine for dry indoor space but will corrode in damp or chemical environments.
7) Can I mount a back panel or DIN rail terminal blocks inside this box?
The 6 inch depth gives you room to work, but the 24186 HC NK is a blank Type 1 enclosure with no knockouts and no panel included. If your design calls for a mounted back panel, order it separately and confirm the panel matches a 24 by 18 inch body before you drill anything.
