B-LINE 16166 RTSC NK – Frequently Asked Questions

1) Can the Eaton B-Line 16166 RTSC NK junction box be mounted outdoors?
Yes. The 16166 RTSC NK is a NEMA 3R enclosure, so it is built for outdoor use against falling rain and dripping water. It comes with a rain hood and plated screws for that service. NEMA 3R does not cover hosedown, washdown, or dust-tight duty, so if the location gets pressure washing or windblown dust you want a 4 or 4X type instead.
2) What are the actual box dimensions of the B-Line 16166 RTSC NK enclosure?
It measures 16 inches high, 16 inches wide, and 6 inches deep. That 6 inch depth is the number to check first if you are stacking terminal blocks, a DIN rail, or wire bundles behind the cover, since the screw cover sits flanged over the opening.
3) Does this B-Line junction box come with knockouts for conduit?
No. The 16166 RTSC NK is the no-knockout version, so every conduit entry gets punched or drilled in the field. That is the usual choice for a 3R outdoor box because you control where the penetrations land and can keep them out of the top surface. If you want factory openings, order a knockout version of the same box instead.
4) How does this enclosure mount to a wall, and does it need a separate mounting kit?
It surface mounts using embossed thru holes in the back of the box, so no external mounting feet or panel brackets are required. You supply the fasteners suited to the wall. Note the holes pass through the enclosure back, so seal the fastener heads if the mounting surface is exposed.
5) What gauge steel and finish is the B-Line 16166 RTSC NK made from?
Carbon steel at 16 gauge, painted in ANSI 61 grey. ANSI 61 is the standard grey used across industrial control gear, so it matches adjacent panels and starters on most plant and utility installs.
6) Is the cover hinged or does it screw on?
Screw cover, flanged. The whole cover comes off when you back out the plated screws, which gives you full access to the 16 by 16 inch opening for pulling and terminating, but it also means you are handling a loose cover on a ladder. If the box will be opened often for service, a hinged door style is the easier choice.
7) How heavy is the 16166 RTSC NK box for a one-person install?
15.1 lb empty. A single installer can hold it to the wall, but with 16 gauge steel and a 16 by 16 inch face it is awkward overhead, so mark and start your top fasteners first before hanging it on them.
