No. The 24248 SC carries a NEMA Type 1 rating, which is indoor use only for protection against incidental contact with enclosed equipment and falling dirt. It gives no protection against rain, hose-down, dust ingress or corrosive environments. For a wet or outdoor location you need a Type 3R or Type 4 enclosure instead.

It measures 24 inches high by 24 inches wide with an 8 inch depth, so plan for a 24 x 24 footprint on the wall and 8 inches of projection off the surface. That depth is what determines whether your conduit bodies, wire bends and any mounted devices clear the screw cover.

Knockouts are already provided: 9 on the sides, 9 on the top, and 9 on the bottom. That gives you factory entries on three faces, so most runs can come in without punching. Anything beyond those locations, or a size the knockouts don't cover, you punch in the field.

Surface mount through the back using the thru holes provided in the box, so it fastens flat to a wall or a strut rack. Weight is 43.1 lb empty, which is a two-person lift on a ladder and means you want the anchors sized for masonry or blocking rather than drywall alone. The cover also has keyhole slots, so it hangs on partly backed-out screws while you set the rest.

A screw cover box like the 24248 SC is for pull, splice and terminal work you don't open often, the cover comes fully off and the plated screws hold it on all four sides. If the box houses controls, breakers or anything a tech opens routinely, go with a hinged door enclosure instead so nobody has to balance a 24 x 24 steel cover on a ladder.

Body is carbon steel at 14 gauge, finished in ANSI 61 gray paint. That is the standard gray that matches most panelboards and control gear, so a run of these on a wall will look consistent with the rest of the electrical room. Painted steel is fine indoors but will corrode in damp or coastal service.

Yes, it is built to UL 50, the enclosure standard for electrical equipment, and carries the NEMA Type 1 indoor rating. It is also made in the US, which helps on jobs with domestic sourcing requirements.

Order Eaton B-Line part number 24248 SC. The digits read as the dimensions: 24 high, 24 wide, 8 deep, with SC for the screw cover enclosure style. B-Line uses that same convention across the family, so a 12 x 12 x 6 screw cover would read 12126 SC.
