B-LINE 24186 RTSC – Frequently Asked Questions

1) Can the B-Line 24186 RTSC enclosure be mounted outdoors?
Yes. The Eaton B-Line 24186 RTSC screw cover enclosure carries a NEMA Type 3R rating, so it is built for outdoor use against rain, sleet and snow, and it includes a rain hood over the cover. It is not a watertight or washdown box, so keep it off surfaces subject to direct hose-down or submersion.
2) What are the box dimensions on the B-Line 24186 RTSC junction box?
It measures 24 inches high, 18 inches wide and 6 inches deep. The 6 inch depth is the number to check first if you are pulling large conductors or mounting a DIN rail or subpanel inside, since bending space is what usually runs out before wall space does.
3) Does the 24186 RTSC come with knockouts already punched?
There are 9 bottom knockouts provided. Bottom entry is the correct approach for a 3R enclosure, since holes in the top or the upper sides of the sidewalls defeat the rain-tight rating. If you need entries elsewhere, they have to be made with listed rain-tight hubs or fittings.
4) How does this B-Line enclosure attach to the wall?
Surface mounting, using embossed thru holes in the back of the box. The embossed pattern holds the enclosure off the mounting surface, which is what you want on an exterior wall so water is not trapped behind the back panel. It is not a flush or recessed box.
5) What gauge steel is the 24186 RTSC, and will it hold up on an exterior wall?
The body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard grey used across most industrial control gear, so it blends with adjacent panels. The box weighs 25.8 lb empty, which matters when you are picking anchors for a masonry or stud wall.
6) Does the 24186 RTSC include a back panel for mounting components?
No inner panel is part of this enclosure. It is supplied as the box, the flanged screw cover with plated screws, and the rain hood. If you plan to mount terminal blocks, relays or a DIN rail inside, order a matching back panel separately and budget for it within the 6 inch depth.
7) What part number do I order for this 24 x 18 x 6 B-Line 3R screw cover box?
Order Eaton B-Line part 24186 RTSC. The number reads directly off the size: 24 high, 18 wide, 6 deep, RTSC for the rain-tight screw cover style. It ships as a single medium single-door style enclosure.
