B-LINE 864 RTSC NK – Frequently Asked Questions

1) Can the Eaton B-Line 864 RTSC NK junction box be mounted outdoors?
Yes. The 864 RTSC NK is a NEMA 3R enclosure, so it is built for outdoor use where falling rain, sleet and ice need to be kept out. It carries a rain hood over the cover and plated screws to handle the exposure, and it is UL 50 listed. NEMA 3R is not a washdown or dust-tight rating, so for hose-down or dusty interiors you want a 4 or 12 enclosure instead.
2) What are the actual box dimensions on the B-Line 864 RTSC NK enclosure?
It measures 8 inches high, 6 inches wide and 4 inches deep. That 4 inch depth is the number that usually decides the job, since it sets how much room you have behind the cover for splices, a small terminal strip or a contactor. The box weighs 3.8 lb.
3) Does the 864 RTSC NK enclosure come with knockouts for conduit?
No. The NK in the model designation means no knockouts, so the box ships blank and you drill or punch your own conduit entries where the run needs them. That is the usual choice for a 3R outdoor box, because you control where the penetrations land and can keep them on the bottom or sides rather than the top. Plan on a hole saw or a knockout punch plus the right fittings for a 16 gauge carbon steel wall.
4) How does this B-Line screw cover box mount to a wall?
It is a surface mount enclosure with embossed thru holes in the back for fasteners, so it bolts flat to a wall, post or strut face. The embossed holes stand the fastener area off slightly, which keeps the seal integrity of the back panel. Anchors and screws suit the substrate and are not part of the box.
5) Is the cover on the 864 RTSC NK hinged or does it unscrew?
Screw cover, not hinged. The flanged cover lifts off once you back out the plated screws, which means you need clear working space in front of the box and a hand free for the cover. For a panel you open often, a hinged door enclosure is the better pick; a screw cover is meant for junction and splice points you rarely revisit.
6) What is the finish on the Eaton B-Line 3R junction box, and will it hold up outside?
Carbon steel, painted in ANSI 61 grey, the standard grey used across most industrial electrical gear so it matches adjacent panels and gutters. Steel with paint is the right call for general outdoor and industrial work; in a coastal or chemical environment, stainless or a non-metallic enclosure is the usual substitute.
