B-LINE 886 RTSC NK – Frequently Asked Questions

1) Can the Eaton B-Line 886 RTSC NK junction box be mounted outdoors?
Yes. The 886 RTSC NK is a NEMA 3R enclosure with a rain hood over the cover, so it is built for outdoor wall mounting where falling rain, sleet and ice are the concern. It is not a washdown or hosedown rating, so keep it off surfaces that get pressure washed or submerged.
2) Does the B-Line 886 RTSC NK box come with knockouts for conduit?
No knockouts. The NK suffix means the box ships blank, so you punch or drill your own conduit entries where you want them. On a 3R enclosure, keep new penetrations on the bottom or lower sides to preserve the rain-tight integrity of the top.
3) What are the actual box dimensions on the Eaton B-Line 886 screw cover enclosure?
It measures 8 inches high, 8 inches wide and 6 inches deep. That 6 inch depth is what gives you room to land conduit bodies, terminal blocks or a small contactor behind the cover rather than just splicing wire.
4) Is the Eaton B-Line 886 RTSC NK box UL listed for a spec job?
It is built to UL 50, the standard covering enclosures for electrical equipment, and it carries a NEMA 3R rating. If the submittal calls for a 3R painted steel screw-cover junction box, those are the two lines the reviewer is looking for. It is made in the US.
5) How does the cover come off on the 886 RTSC NK, and can one person do it on a ladder?
It is a screw cover with a flanged edge and plated screws, so you back out the screws and lift the cover clear. The whole enclosure weighs 5.7 lb, so it is a one-person set and a one-person open. Screw covers are slower to open than a hinged door, so if the box gets serviced often, a hinged-door enclosure is the better choice.
6) How does this B-Line 8x8x6 enclosure attach to a wall?
Surface mount through embossed thru holes in the back panel. The embossing stands the box off the mounting surface slightly, which keeps water from wicking behind it on an exterior wall. Anchors and fasteners are chosen for your substrate and are not part of the enclosure.
7) What is the 886 RTSC NK enclosure made of and will it hold up outside?
Carbon steel at 16 gauge, painted ANSI 61 grey. The 16 gauge body resists denting on a loading dock or equipment yard better than a thin-wall box, and the paint is the corrosion barrier, so touch up any field-drilled holes or scratches before you energize it.
8) Do I need a mounting panel or back plate with the B-Line 886 screw cover box?
The 886 RTSC NK is a small single door style junction enclosure, supplied as the box, the flanged screw cover and its plated screws. If you intend to mount devices inside rather than just splice, order a back panel sized to the 8 x 8 box separately, along with your conduit hubs or fittings, since the box ships with no knockouts.
9) Will the ANSI 61 grey finish match the other enclosures already on my building?
ANSI 61 grey is the standard grey used across most industrial control and junction enclosures, so the 886 RTSC NK will read as a match alongside typical panel and disconnect enclosures on the same wall. For a facility standardizing on one look, that plus the 3R rating makes it repeatable across exterior openings.
