B-LINE 1084 RTSC NK – Frequently Asked Questions
1) Can the Eaton B-Line 1084 RTSC NK junction box be mounted outdoors?
Yes. The 1084 RTSC NK is a Type 3R enclosure, so it is built for outdoor use where falling rain, sleet and ice need to be kept out of the wiring. It ships with a rain hood over the door and plated screws, and the body is painted carbon steel in ANSI 61 grey. It is not a washdown or hosedown rating, so skip it for pressure-wash or submersion areas.
2) What size is the B-Line 1084 RTSC NK enclosure, and will it take my wiring gutter space?
The box measures 10 inches high, 8 inches wide and 4 inches deep. That 4 inch depth is what decides whether a terminal block, small contactor or a bundle of conduit fittings will sit inside with the door closed, so measure your tallest device plus wire bend space against it before ordering.
3) Does the 1084 RTSC NK come with knockouts?
No. The NK in the model designation means no knockouts, so the enclosure arrives blank and you punch your own conduit entries where you want them. On a 3R box that is usually the preference anyway, since you control where penetrations land relative to the rain hood. Plan on a knockout punch or hole saw plus rated hubs or fittings to keep the 3R integrity.
4) How does this B-Line junction box mount to a wall?
It is a surface mount enclosure with embossed through holes in the back for fasteners. The embossed pattern holds the box body off the mounting surface, which keeps water from sitting behind it on an exterior wall. At 5.4 pounds empty, standard anchors sized to your substrate will carry it, but size for the loaded weight once devices and conduit are in.
5) How does the cover attach on the Eaton B-Line 1084 RTSC NK, hinged or screw-on?
Screw cover, not hinged. It is a flanged cover secured with plated screws, so the cover lifts off completely during work rather than swinging open. If your crew needs frequent access at height, a hinged door enclosure is easier to work in. For a set-and-forget pull or splice point, the screw cover is the cleaner seal.
6) Is the 1084 RTSC NK junction box UL listed for a spec-driven job?
It carries UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. That is usually what an inspector or a submittal reviewer is looking for alongside the Type 3R rating on an outdoor enclosure.
7) What gauge steel is the B-Line 1084 RTSC NK, and is it heavy enough for an exterior utility wall?
16 gauge carbon steel throughout, painted in ANSI 61 grey. That is standard commercial weight for a 3R pull and junction box and stands up to being bumped in a mechanical room, loading dock or rooftop run. Painted steel does mean touching up any field-drilled edges so they do not rust at the penetration.
