Metallic Enclosure for Bus Plugs

The Wiegmann B-SC enclosure houses bus plugs in industrial and commercial electrical systems. Its carbon-steel body with ANSI 61 powder coat protects internal components from dust, dripping liquids and oil. The unit meets NEMA 12 and 13 ratings and carries cULus and CSA certifications.

Wall-Mount Installation with Captive Screws

Mount the enclosure using the external plates and secure the cover with captive screws that stay in place during maintenance. A neoprene gasket seals the joint without extra hardware. The solid cover has no knockouts, so cable entries must be cut on site if required.

Limited to NEMA 12 and 13 Environments

The enclosure is rated for indoor use where falling dirt, circulating dust and non-corrosive liquids are present. It is not suited for outdoor exposure, hose-down cleaning or hazardous locations. Usable interior depth is 3.88 in, which restricts the size of components that can be fitted.

Questions about this item

How do I confirm the enclosure is providing the rated protection after I mount it?

Verify the captivated cover screws are fully seated, the neoprene gasket is compressed evenly and the ANSI 61 powder coat is intact; the unit carries CSA, cULus and UL listings for NEMA 12 and 13.

What ships with the B-SC enclosure and what must I source separately?

The box includes the carbon-steel body with external mounting plates, the solid cover with captivated screws and the neoprene gasket; the 6XC21 interior panel and any bus-plug components are sold separately.

Which B-SC version should I choose for a wall-mount application needing a 3.88 in usable depth?

Select the 8 in height, 8 in width, 4 in depth model in 14 ga carbon steel with screw closure; it delivers the listed 3.88 in usable opening depth and meets NEMA 12, 13 ratings.
