Yes, within the limits of NEMA 3R. The 242410 RTSC is rated Type 3R, which means it sheds falling rain, sleet and snow and resists external ice formation, and it includes a rain hood over the cover. It is not a washdown or hosedown box, so if the location sees direct spray, pressure washing or dust ingress, you want a Type 4 or 12 enclosure instead.

24 inches high by 24 inches wide with a 10 inch depth. That depth is the number that usually decides it, since it sets how much room you have behind the cover for terminal blocks, wire bend radius and gutter space. Wall construction is 14 gauge carbon steel.

There are 9 knockouts in the bottom of the box. The sides, back and cover ship solid, so any top or side entry has to be field punched, and top penetrations on a 3R box should be avoided or properly hubbed to keep the rain rating intact.

Surface mount, using embossed thru holes in the back of the enclosure so the fasteners pass through raised bosses rather than the flat panel. That keeps the mounting screws from becoming a leak path on an outdoor 3R box. Plan the anchors for the load: the enclosure alone is 49.3 lb before any devices or wire go in it.

It is a screw cover, flanged, not hinged. The flange overlaps the box opening, which is how the 3R rain performance is achieved, and the screws are plated to resist corrosion outdoors. Practical consequence: if you need frequent access for testing or resetting devices, a hinged-door enclosure is the better choice, because this cover comes off entirely and has to be handled at 24 by 24 inches.

Yes. 14 gauge carbon steel walls are the usual commercial and industrial weight for a box this size and will carry a back panel, DIN rail or terminal blocks without oilcanning. Note that no panel or mounting hardware for the interior is described as part of the enclosure, so plan on ordering the back panel and internal hardware separately.

Painted ANSI 61 grey, which is the standard grey used across most industrial control and distribution equipment, so it lines up visually with switchgear, panelboards and other B-Line enclosures on the same wall. Carbon steel under the paint, so scratches should be touched up if the box lives outdoors.

Country of origin is the US, which matters if the job carries a domestic sourcing requirement on electrical materials, as many government, institutional and transit specs do.
