Galvanized Steel Enclosure SC-G Series

This galvanized steel enclosure provides NEMA 1 rated protection for electrical components in indoor environments. It suits installers who need a compact, wall-mountable housing with a solid cover for line protection circuits. The 16-gauge construction and plated steel screws deliver durability for industrial and commercial applications. The silver finish resists corrosion in typical indoor conditions.

Upgrade From Open Wiring Or Non-Rated Boxes

The enclosure replaces makeshift junction boxes or open wiring setups that lack a certified NEMA rating. The jump is worth it when local codes require a listed enclosure for bus plugs or similar devices. Embossed mounting holes and included self-tapping screws simplify the transition from unprotected installations. The solid cover prevents accidental contact with live parts.

Straightforward Wall Mount With Included Hardware

Installation uses the embossed mounting holes for direct wall attachment without separate brackets. Self-tapping screws are supplied, so no additional fasteners are needed for the cover or mounting. The screw-on cover closes securely but requires a driver for access, which slows frequent inspections. Usable opening depth of 3.88 inches limits the size of internal components that can fit.

Questions about this item

What wall space and screw size do the embossed mounting holes on this 4.00 In. galvanized steel enclosure require?

The enclosure measures 4.00 In. high by 4.00 In. wide and has embossed mounting holes for wall mounting; it includes self-tapping screws for fastening.

How is the solid cover secured, and what step do installers often miss with the self-tapping screws?

The cover uses plated steel screws that thread into the enclosure body; a common mistake is not pre-drilling pilot holes when the metal gauge is 16, which can strip the threads.

When should the self-tapping screws or the plated cover screws be replaced on this NEMA 1 enclosure?

Replace any screw that shows corrosion, stripped heads, or damaged threads; the galvanized finish and plated screws resist rust, but hardware should be inspected during routine electrical maintenance.
