No. The 30186 SCGV NK carries a NEMA Type 1 rating, which covers indoor use only and protects against incidental contact and falling dirt. It gives no protection against rain, hose-down, dust or oil, so keep it indoors in a dry location. For a wet or outdoor location you need a Type 3R, 4 or 4X enclosure instead.

It measures 30 inches high, 18 inches wide and 6 inches deep. The 6 inch depth is what usually decides the job, since it sets how much room you have behind the screw cover for gutter space, terminal blocks and wire bending radius. Plan your surface space for a 30 by 18 footprint on the wall.

No knockouts. The 30186 SCGV NK is supplied blank, so every conduit entry gets drilled or punched on site where you want it. That is an advantage when you are coordinating multiple runs, but budget for a hole saw or knockout punch set, plus connectors and sealing hardware, before the box goes on the wall.

It is a surface mount box with thru holes in the back pan, so you fasten it directly to the wall or structure with your own anchors or lags, sized to the substrate. The box weighs 31 pounds empty, so into masonry or drywall you want anchors rated well past that once conductors and devices are added, or hit studs or Unistrut behind it. No mounting hardware is included with the enclosure.

It is built to UL 50, the standard for enclosures for electrical equipment, and it is made in the US. Those two points cover the usual submittal questions on institutional and government work where domestic origin and a UL 50 enclosure standard are called out on the drawings.

A screw cover box like the 30186 SCGV NK is meant for pull points, splices, gutter and terminal work you rarely reopen. The whole cover comes off with plated screws, giving unobstructed access to all four sides of the interior for pulling cable. If someone needs to get in routinely, such as for controls or metering, a hinged cover enclosure is the better pick because you are not handling a loose 30 by 18 panel every time.

Order Eaton B-Line 30186 SCGV NK. The number reads off the dimensions: 30 inch height, 18 inch width, 6 inch depth, SCGV for screw cover galvanized, NK for no knockouts. If you need the same size with knockouts or a different cover style, that suffix is what changes.
