No. The 363610 SC NK is a NEMA Type 1 enclosure, which is indoor-use only. It protects against incidental contact with the enclosed equipment and falling dirt, but it is not sealed against water, oil, coolant or dust. For an outdoor wall, a hosed-down kitchen, or a mechanical room with dripping pipes, you need a Type 3R, 4 or 12 enclosure instead.

36 inches high, 36 inches wide, and 10 inches deep. That depth is what usually decides the job, since 10 inches gives room for gutter taps, terminal blocks or bending space behind a subpanel feed. The 363610 model number reads directly as 36 x 36 x 10.

No knockouts. The SC NK enclosure ships blank, so every conduit entry gets located and punched in the field with a knockout punch or hole saw. That is usually what you want on a 36 x 36 gutter or pull box, because you set the entries to match your actual conduit runs rather than working around factory holes.

Surface mount, using thru holes in the back of the box. The cover also has keyhole slots so it can be hung and started on a few screws before the rest go in, which matters on a box this size. At 102.3 lb empty, plan on blocking, unistrut or solid masonry anchors rather than drywall fasteners, and get a second set of hands on it.

A screw cover box like the 363610 SC NK is meant for openings you rarely need to get into: pull boxes, junction points, wireway taps. The cover comes off entirely with plated screws, so on a 36 x 36 cover that is a two-hand job on a ladder. If someone will be opening it regularly to reset a device or land wire, choose a hinged cover enclosure instead so the cover stays captive.

12 gauge carbon steel body. That is the heavier end of the range for Type 1 enclosures and it is why the box weighs 102.3 lb. It holds its shape when you punch conduit entries and carries the weight of multiple large feeders without oil-canning.

It carries UL 50, the standard covering enclosures for electrical equipment, and it is made in the US. UL 50 plus the Type 1 rating is what an inspector looks for on an indoor pull or junction box.

Painted ANSI 61 grey, which is the standard grey used on most switchgear, panelboards and industrial control enclosures. If you are standardizing a plant or a facility on grey electrical gear, it lines up without field painting.
