B-LINE 24126 RTSC NK – Frequently Asked Questions
1) Can the B-Line 24126 RTSC NK junction box be mounted outdoors?
Yes. The Eaton B-Line 24126 RTSC NK is a Type 3R enclosure, which is the rating for outdoor use against falling rain, sleet and snow. It carries a rain hood over the cover and plated screws for the exposed hardware, and the carbon steel body is painted ANSI 61 grey. It is not a washdown or submersion enclosure, so if you need protection against directed hose spray or oil, step up to a Type 4 or 4X box.
2) Does this Eaton B-Line junction box come with knockouts?
No. The NK in 24126 RTSC NK means no knockouts, so the box ships with solid walls and you punch your own conduit entries where the job needs them. Plan on a hole punch or step bit for the 16 gauge carbon steel, and keep penetrations out of the top face to preserve the 3R rating.
3) What are the box dimensions on the B-Line 24126 RTSC NK enclosure?
It measures 24 inches high by 12 inches wide with a 6 inch depth, which is where the 24126 designation comes from. That 6 inch depth is the number to check first if you are stacking terminal blocks or landing large conduit fittings on the back pan. Shipping weight is 17 lb, so it is a one-person hang.
4) How does the 24126 RTSC NK enclosure mount to a wall?
Surface mount. The back has embossed thru holes, so you run your fasteners straight through the box into the wall or strut. Because the mounting holes are embossed rather than external feet, the box sits flat against the surface, and the fasteners you use are not supplied.
5) Is the cover on the B-Line 24126 RTSC NK hinged or removable?
Removable. It uses a flanged cover secured with screws rather than a hinge and latch, so plan on lifting the cover clear during service and having a hand free for it. The screws are plated for outdoor exposure. If you want a door you can swing open and leave open, look at a hinged-cover 3R enclosure instead.
6) Is this junction box UL listed for a commercial or institutional install?
The 24126 RTSC NK is built to UL 50, the standard for enclosures for electrical equipment, and it is manufactured in the US. For spec submittals, the other figures inspectors ask for are the Type 3R rating and the 16 gauge carbon steel body.
7) Will a painted steel 3R box hold up outdoors, or should I be looking at stainless?
The 24126 RTSC NK is painted carbon steel in ANSI 61 grey with plated screws, which is the normal choice for exterior walls, rooftops and yard equipment in ordinary weather. In coastal salt air, a wash-down bay, or anywhere corrosive chemicals get on the box, painted carbon steel is the wrong call and a stainless Type 4X enclosure is what you want.
