B-LINE 242412 RTSC NK – Frequently Asked Questions

1) Can the B-Line 242412 RTSC NK enclosure be mounted outdoors?
Yes. The 242412 RTSC NK carries a NEMA 3R rating, which covers outdoor use against falling rain, sleet and snow, and it includes a rain hood over the cover. It is not a washdown or hosedown enclosure, so if you need protection against directed water spray you want a Type 4 box instead.
2) What are the box dimensions of the B-Line 242412 RTSC NK junction box?
24 inches high, 24 inches wide and 12 inches deep. That 12 inch depth is what decides most jobs, since it sets how much gutter space you have behind gland plates or terminal blocks.
3) Does this B-Line enclosure come with knockouts for conduit?
No. The 242412 RTSC NK is a no-knockout box, so every conduit entry has to be field punched or drilled where you want it. That is the usual choice on a 3R outdoor box, because you control where holes land relative to the rain hood and keep unused openings out of the weather.
4) How does this 24 x 24 B-Line box mount to a wall or strut?
Surface mount, using embossed thru holes in the back of the enclosure. The embossments keep the mounting hardware from breaking the seal plane. Mounting bolts, strut and anchors are a field supply item, sized to your substrate.
5) Is the B-Line 242412 RTSC NK enclosure UL listed, and where is it made?
It is built to UL 50, the standard for enclosures for electrical equipment, and it is manufactured in the US. The UL 50 reference and US origin are what most institutional and government specs are looking for on a submittal.
6) How is the cover on the 242412 RTSC NK secured, and can it be opened for service?
It is a flanged screw cover with plated screws, so the whole cover lifts off when you back the screws out. Fine for a pull or terminal box you open occasionally; if crews need frequent access, a hinged-door enclosure with latches is the better pick.
7) How heavy is the B-Line 242412 RTSC NK, and is it a one-man hang?
53.7 lb empty. With a 24 x 24 face and that weight, plan on two people to set it and mount it to strut or a backing plate rather than a single anchor pattern in drywall or block.
8) What gauge steel is the 242412 RTSC NK enclosure, and what finish does it ship in?
14 gauge carbon steel, painted ANSI 61 grey. That is the standard industrial grey that matches most panelboards and control gear, so it blends into an existing lineup. Steel, not stainless, so keep it out of corrosive or coastal salt-spray service.
9) What is the correct part number to order this B-Line 24x24x12 screw cover 3R box?
Order Eaton B-Line part number 242412 RTSC NK. The digits are the dimensions (24 high, 24 wide, 12 deep), RTSC is the rainproof screw cover style, and NK means no knockouts.
