B-LINE 16124 RTSC NK – Frequently Asked Questions

1) Can the Eaton B-Line 16124 RTSC NK junction box be mounted outdoors?
Yes. The 16124 RTSC NK is a NEMA 3R enclosure, so it is built for outdoor use where falling rain, sleet and ice need to be kept off the wiring. It carries a rain hood over the cover and plated screws to hold up outside. NEMA 3R is not a washdown or hosedown rating, so skip it for direct spray or dust-tight duty.
2) What are the actual box dimensions of the B-Line 16124 RTSC NK enclosure?
It is 16 inches high, 12 inches wide and 4 inches deep. That 4 inch depth is the number to watch: it sets how much room you have behind the cover for splices, terminal blocks or a small device, and how far the box stands off the wall once surface mounted.
3) Does this B-Line RTSC enclosure come with knockouts?
No. The NK in 16124 RTSC NK means no knockouts, so the box ships blind and you punch your own conduit entries where the job needs them. That is the usual choice on a 3R box, since you want entries in the bottom or lower sides rather than the top. Plan on a hole punch and the right rain-tight fittings.
4) How does the 16124 RTSC NK mount to a wall, and does it need separate brackets?
It surface mounts directly using embossed thru holes in the back of the box, so no external mounting feet or brackets are part of the design. Anchors or fasteners suited to your wall material are supplied by the installer. At 10.4 lb empty, standard masonry or structural anchors handle it easily.
5) Is this a hinged door enclosure or a screw cover box?
Screw cover, not hinged. The flanged cover fastens with plated screws, which means you need both hands and a driver to open it. For a box you expect to open often for service, a hinged cover version is the better pick; screw cover suits pull points and splice boxes you rarely revisit.
6) What gauge steel is the B-Line 16124 junction box, and how is it finished?
The body is 16 gauge carbon steel, painted ANSI 61 grey. That is the standard grey used across industrial gear, so it blends with switchgear and panel lineups already on site. Steel construction means paint damage from a punch or a scrape should be touched up before it sits outdoors.
7) Is the B-Line 16124 RTSC NK made in the USA?
Yes, country of origin is the United States. That matters on public and institutional work where domestic sourcing is written into the spec.
