Compact Steel Junction Box

The Wiegmann SC121204 is a NEMA 1 rated enclosure built from 16 gauge carbon steel with an ANSI 61 gray powder coat. It measures 12 inches high, 12 inches wide and 4 inches deep, providing a usable opening depth of 3.88 inches. The solid cover secures with plated steel screws and the box includes self-tapping screws for mounting. It carries CSA, cULus and UL Listed certifications for indoor line protection.

Indoor Electrical Installers

This enclosure suits electricians and maintenance teams terminating conduit or mounting bus plugs inside dry, non-hazardous locations. The embossed mounting holes simplify wall installation and the screw-on cover keeps wiring secure yet accessible. It is not intended for outdoor exposure, wash-down areas or hazardous atmospheres that demand a higher NEMA rating or a gasketed seal.

3.88 Inch Usable Depth

The 3.88 inch usable opening depth determines which bus plugs, terminal blocks or splice kits will fit inside the box. Verify your component dimensions against this clearance before purchase. The 16 gauge steel walls and plated hardware complete the mechanical specification.

Questions about this item

Does the Wiegmann SC121204 enclosure ship with mounting hardware or must I purchase screws separately?

The box includes self-tapping screws for the cover; the embossed mounting holes accept standard lag bolts or anchors that you supply for wall installation.

The spec sheet lists a single 12x12x4 size — how do I know this model fits my component layout?

The usable opening depth is 3.88 inches, giving you that exact internal clearance for DIN rail, terminal blocks or small breakers before the cover closes.

What does the NEMA 1 rating on this carbon-steel box mean for everyday use in a workshop?

NEMA 1 provides basic indoor protection against falling dust and incidental contact; the ANSI 61 powder coat resists corrosion in dry, non-hazardous locations.
