B-LINE 24188 SC – Frequently Asked Questions

1) Can the B-Line 24188 SC junction box be used outdoors or in a wash-down area?
No. The 24188 SC is a NEMA Type 1 enclosure, which is indoor use only, for protection against incidental contact and falling dirt. It has a screw cover, not a gasketed one, so it is not rated against water, dust or oil. For an outdoor or wet location you need a Type 3R or Type 4 enclosure instead.
2) What are the actual box dimensions on the B-Line 24188 SC screw cover enclosure?
It measures 24 inches high, 18 inches wide and 8 inches deep. The 8 inch depth is what usually decides the job, since that is the room you get behind the cover for splices, terminal blocks or gutter taps once the box is on the wall.
3) Does this B-Line junction box come with knockouts already, or do I have to punch my own?
Knockouts are provided: 9 on the sides, 9 on the top, 9 on the bottom. That covers most conduit entries without pulling out a punch, though the box is 16 gauge carbon steel if you do need to add an opening.
4) How does the 24188 SC mount to the wall, and does it mount through the back?
Surface mounting through the back, using thru holes in the back panel. Fasteners are not part of the box, so pick anchors to suit the substrate and the 28.1 lb empty weight plus whatever wiring and devices you put inside.
5) Is a screw cover box like this the right choice, or should I use a hinged door enclosure?
A screw cover box suits an enclosure you open rarely, such as a splice or pull point, because the cover comes fully off and has to be held while you refit the screws. If someone will be inside it regularly for testing or adjustment, a hinged door enclosure is the easier choice. The 24188 SC does have keyhole slots on the cover, so the cover can be dropped onto partly backed-out screws and then tightened, which makes one-person installation manageable.
6) Is the B-Line 24188 SC junction box UL listed?
It is built to UL 50, the standard covering enclosures for electrical equipment. Country of origin is the US.
7) How heavy is this box and will corrosion be an issue in a damp mechanical room?
Empty weight is 28.1 lb, so it is a two-hand lift to set on the wall. The body is carbon steel with a painted finish and plated cover screws. That is fine for dry indoor spaces, but in a damp or corrosive area a painted carbon steel Type 1 box is the wrong pick, go to stainless or a sealed Type 4X.
8) What color and finish is the B-Line 24188 SC, and will it match other enclosures on the job?
Painted finish in ANSI 61 grey, the standard grey used across most commercial electrical enclosures, so it will read the same as the rest of the gear in a typical electrical room.
