Electrical enclosure for wall-mount protection

The Wiegmann SC181808 is a NEMA 1 rated carbon-steel enclosure finished in gray paint. It measures 18 inches high, 18 inches wide and 8 inches deep with a usable opening depth of 7.88 inches. The solid cover secures with plated-steel captive screws and the box includes self-tapping screws for installation. The 16-gauge construction suits indoor line-protection applications.

Verify mounting space and cover clearance

Confirm the wall area can accommodate the 18 by 18 inch footprint and allow the screw-on cover to be removed fully. Ensure the 8 inch depth fits behind any planned panel or conduit runs. The embossed mounting holes accept standard hardware; check that the supplied self-tapping screws match your wall material before starting.

Steel body dissipates heat without active cooling

The painted carbon-steel shell acts as a passive heat sink for breakers or terminal blocks mounted inside. Under continuous load the enclosure surface warms evenly and radiates heat into the surrounding air. No fans or vents are present, so sustained internal temperature depends on ambient conditions and the heat output of the installed devices.

Questions about this item

Does the SC181808 enclosure come with mounting hardware or must I buy screws separately?

The enclosure includes self-tapping screws for mounting the cover. Embossed mounting holes are provided for wall installation; separate lag bolts or anchors are required to secure the box to the wall.

Should I choose the 18 in height model or a different size for a standard 16 ga carbon steel cabinet?

This SC series unit is 18 in high, 18 in wide and 8 in deep with a 16 ga carbon steel body. Select it when those exact outside dimensions and gauge match your panel layout; other sizes are separate part numbers.

What does the 7.88 in usable opening depth mean for fitting components inside the enclosure?

It is the clear internal depth available after the cover is fastened. Any DIN rail, terminal block or relay must not exceed 7.88 in front-to-back including wiring bend radius.
