SEPCO 27BI4OL Insulated Grounding Bushing with Aluminum Lug, Zinc-Plated Malleable Iron, 3-Inch

SEPCO Insulated Grounding Bushing with Aluminum Lug, Zinc-Plated Malleable Iron, 3-Inch

SEPCO’s Insulated Grounding Bushing is designed for reliable conduit termination and grounding continuity in electrical raceway systems. Constructed from zinc-plated malleable iron for corrosion resistance and mechanical strength, this 3-Inch bushing features an open-side aluminum lug that simplifies bonding jumper connections without requiring the bushing to be removed from the conduit. The molded insulated throat protects conductor insulation from abrasion as wires pass through the fitting, helping installers maintain a clean, code-conscious termination point at panelboards, enclosures, and equipment housings. This bushing is a practical, dependable choice for electricians and contractors who need a durable grounding fitting for commercial, industrial, and light-duty raceway work.

Key Features

• Trade Size: Sized for 3-Inch conduit, ensuring a proper, secure fit within standard rigid or IMC raceway systems.
• Durable Construction: Zinc-plated malleable iron body resists corrosion and rust while providing the mechanical strength needed for demanding installation environments, indoors or out.
• Insulated Grounding Design: The insulated throat shields conductor insulation from abrasion and cutting at the point where wires exit the conduit, reducing the risk of nicked or damaged conductors over time.
• Open Side Aluminum Lug: Features an open-side aluminum grounding lug that allows a bonding jumper conductor to be attached, adjusted, or removed without disturbing the conduit connection itself, saving installation time.
• Finish: Zinc-plated finish adds an extra layer of corrosion protection, supporting long-term reliability in typical raceway environments.
• Grounding Continuity: Provides a mechanical and electrical bonding path between conduit and enclosure, supporting proper equipment grounding practices.
