B-LINE 10108 RTSC NK – Frequently Asked Questions
1) Can the B-Line 10108 RTSC NK junction box be used outdoors?
Yes, it is built for outdoor use. The Eaton B-Line 10108 RTSC NK carries a NEMA 3R rating, which means it protects against falling rain, sleet and snow and external ice formation, and it includes a rain hood over the cover. It is not a washdown or hosedown enclosure, so keep it out of locations where it will take direct pressurized spray.
2) What are the box dimensions of the 10108 RTSC NK enclosure?
The enclosure measures 10 x 10 x 8 inches, with height listed at 10 inches, width at 10 inches and length/depth at 8 inches. It weighs 9.1 lb, so one person can set and hold it while driving the mounting fasteners.
3) Does this Eaton B-Line junction box come with knockouts or do I have to punch my own holes?
No knockouts. The NK in 10108 RTSC NK means no knockouts, so the box arrives blank and you locate and punch every conduit entry yourself. That is the right choice when you want the entries where your raceway actually lands, and on a 3R outdoor box it lets you keep penetrations off the top face. Plan on a punch set or step bit plus rated fittings and sealing washers for each hole.
4) Is this junction box UL listed for a spec job?
The 10108 RTSC NK is built to UL 50, the standard for enclosures for electrical equipment, and it is made in the USA. Between UL 50 and the NEMA 3R rating it covers the usual submittal line for a rain-tight surface junction or pull box.
5) How does the cover attach, and can I get into it repeatedly for service?
The cover is a flanged screw cover using plated screws, so it comes off completely rather than swinging on a hinge. Fine for a pull box or splice point you open occasionally; if your crew needs frequent access at a terminal or control point, a hinged-door enclosure is easier to live with because you are not juggling loose screws on a ladder.
6) How is this box mounted, and are mounting holes already provided?
It is a surface-mount enclosure with embossed thru holes in the back for fasteners. The embossing stands the hole off the mounting surface, which keeps water from tracking in at the fastener and keeps the 3R integrity intact. Anchors and screws suit the wall or strut you are landing on and are not part of the box.
7) What gauge steel and finish is the 10108 RTSC NK, and will it hold up outside?
Body is 16 gauge carbon steel with a painted finish in ANSI 61 grey, the standard grey you see across industrial gear so it blends with existing panels on a facility. Painted steel is suited to general outdoor and damp exterior locations; for coastal, chemical or corrosive duty, step to a stainless or non-metallic enclosure instead.
