Wiegmann SC181806 Carbon Steel Enclosure

The Wiegmann SC181806 is a NEMA 1 rated wall-mount enclosure made from 16 ga carbon steel with ANSI 61 powder-coated gray finish. It measures 18 in height, 18 in width, and 6 in depth with a usable opening depth of 3.88 in. The solid cover uses captive plated steel screws and includes self-tapping mounting screws. It is UL Listed, cULus, and CSA Certified for indoor line protection applications.

Pre-Installation Checks

Verify the mounting surface can support the enclosure and that the 18 in by 18 in footprint fits the allocated space. Confirm the 6 in overall depth and 3.88 in usable depth accommodate your internal components and wiring bend radii. Ensure the NEMA 1 rating matches the environmental conditions, as this unit is not rated for outdoor or wash-down use. Check that the captive screw closure method meets your access and security requirements.

Sustained Load Behavior

The 16 ga steel construction and powder-coated finish provide consistent structural rigidity and corrosion resistance during continuous indoor operation. Captive plated steel screws maintain reliable cover retention through repeated thermal cycling without loosening. Embossed mounting holes preserve alignment integrity over long-term vibration exposure. The enclosure maintains its NEMA 1 protection rating and certifications under sustained electrical and mechanical load conditions.
