Overview

The ABB 3-1/2 Inch Threaded Insulated Grounding Bushing (SKU: 3863) is a precision-engineered component designed for secure grounding and conduit protection in electrical installations. Manufactured by ABB - Installation Products, this bushing features a cast malleable iron body with an electro-zinc plated finish, ensuring durability and corrosion resistance in industrial environments. The threaded design provides a reliable connection to Rigid and Intermediate Metal Conduit (IMC), with compatibility for conduit sizes up to 3-1/2 inches. This grounding bushing accommodates conductor sizes ranging from 8 AWG to 2/0 AWG, making it suitable for a wide variety of electrical systems. The integrated thermoplastic insulator, rated for 150°C (302°F) applications, prevents conductor insulation damage and accidental contact, enhancing electrical safety. The lay-in lug design simplifies installation, allowing for quick bonding jumper attachment to multiple metal conduits. Key features include a cast iron body that locks the insulator in place, reducing common assembly issues such as insulator dislodging. The thermoplastic insulator meets 94V-0 flammability standards, ensuring reliable performance in high-temperature environments. Applications include commercial and industrial facilities, manufacturing plants, power distribution systems, and any environment where reliable grounding and conduit protection are critical. The bushing’s robust construction and straightforward installation make it a dependable choice for electricians and contractors seeking long-term performance in demanding electrical systems.

How to Install the 3870 Series Threaded Grounding Bushing

This guide provides step-by-step instructions for installing the 3870 Series Threaded Grounding Bushing, including securing it to conduit and connecting the bonding jumper.

Estimated time: 15m

Tools needed:

Screwdriver

Supplies needed:

Conduit, Bonding jumper, Copper or aluminum wire

  1. Thread the bushing onto the conduit

    Thread the grounding bushing onto the conduit until it bottoms. If necessary, the bushing may be backed off slightly to align the lay-in lug in the desired position.

  2. Secure the bushing

    Tighten the set screw to firmly secure the bushing onto the conduit.

  3. Install bonding jumper and connect wire

    Install a bonding jumper (not supplied) into the lay-in lug. Torque the wire clamping screw to the values specified in the provided torque table for the specific wire gauge and material (copper or aluminum).
