Overview

The ABB BU 404 is a 1-1/4 inch iron-zinc plated bushing designed for use with rigid and intermediate metal conduit (IMC) systems. This bushing provides a secure connection between conduit and electrical enclosures, ensuring proper grounding and electrical continuity in industrial and commercial installations. The durable iron-zinc plated finish offers corrosion resistance, extending service life in demanding environments. Engineered to meet stringent industry standards, the BU 404 features a cast malleable iron body with a thermoplastic insulator rated for 150°C (302°F) applications. The lay-in lug design simplifies installation, while the insulator locks securely within the body to prevent dislodging during assembly. This bushing is ideal for applications requiring reliable conduit fittings, including electrical contractors and maintenance professionals working in harsh conditions. The BU 404 is manufactured by ABB Installation Products and is compatible with standard 1-1/4 inch rigid and IMC conduit systems.
