Overview

The ABB BU 407 is a 2-1/2 inch iron-zinc plated bushing designed for use with rigid and intermediate metal conduit (IMC) systems. This bushing provides a secure threaded connection between conduit and enclosures, ensuring electrical continuity and mechanical stability. The iron-zinc plating offers enhanced corrosion resistance, making it suitable for industrial, commercial, and outdoor applications where exposure to moisture or chemicals is a concern. With a durable construction and precise threading, the BU 407 meets industry standards for conduit fittings, including UL and NEMA compliance. It is ideal for electrical contractors, maintenance teams, and facility managers who require reliable, long-lasting conduit protection. The bushing’s 2-1/2 inch size accommodates standard trade sizes for rigid and IMC conduit, providing compatibility with common electrical installations. Installation requires no special tools beyond a standard conduit wrench or screwdriver, simplifying field deployment.
