No. The 30248 SCGV NK carries a NEMA Type 1 rating, which covers indoor use only, protecting against incidental contact and falling dirt. It offers no rain, sleet, hosedown or dust-tight protection, so outdoor, damp, wet or washdown locations need a Type 3R, 4 or 4X enclosure instead. Indoor electrical rooms, mechanical spaces and back-of-house pull box applications are what this one is built for.

It measures 30 inches high, 24 inches wide and 8 inches deep, which is where the 30248 designation comes from. That 8 inch depth is the number to check first: it decides your conductor bending space and whether the box will sit clear of anything in front of the wall once it is surface mounted. Assembled weight is 50.2 lb, so plan the wall anchors accordingly.

It ships with no knockouts. The NK in 30248 SCGV NK means blank walls, so every conduit entry gets located and punched in the field with a hole saw or knockout punch. That is an advantage on a job where the conduit layout is already set, but budget the labor: the body is 14 gauge galvanized steel, heavy enough that you want a hydraulic punch rather than a step bit for larger trade sizes.

Surface mount, using thru holes in the back of the box. You bolt or lag it directly to the wall or to unistrut, and because it is a thru-hole pattern the fasteners pass through the enclosure interior, so allow room to reach them before the wiring goes in. At 50.2 lb empty, mount into studs, masonry anchors or strut rather than drywall anchors.

It is a screw-on lift-off cover, not a hinged door. B-Line puts keyhole slots on the cover so you can back the screws out part way, lift the cover off the slots and rehang it one-handed instead of juggling loose hardware, and the screws are plated. If you need a door that swings and latches for frequent access, specify a hinged cover enclosure instead of a screw cover type.

Yes, it is built to UL 50, the standard for enclosures for electrical equipment, and it is a NEMA Type 1 enclosure. That combination is what an inspector or a spec writer on an institutional job will be looking for on an indoor pull or junction box. It is manufactured in the US, which matters on Buy American and federally funded work.

The manufacturer part number is 30248 SCGV NK from Eaton's B-Line series. Read it as 30 high by 24 wide by 8 deep, SC for screw cover, GV for galvanized, NK for no knockouts. If you need the same footprint with knockouts or a painted finish, the suffix is what changes, so quote the full string when you order.

Unfinished galvanized steel, grey in appearance, with no paint topcoat. The zinc coating is there for corrosion resistance in indoor electrical and mechanical rooms, not for looks. If it is going in a tenant space or anywhere on a finished wall, either specify a painted ANSI grey enclosure or plan to prime and paint the galvanized surface yourself.
