Overview

The ABB 6-inch threaded insulated grounding bushing (SKU: 3999) is a critical component for secure grounding in rigid and IMC conduit systems. Constructed from durable iron and finished with electro-zinc plating, this bushing delivers superior corrosion resistance in industrial environments, ensuring long-term reliability. The integrated thermoplastic insulator provides essential electrical isolation, preventing short circuits and enhancing safety in electrical distribution systems. Designed for conduit sizes up to 6 inches, this grounding bushing accommodates wire ranges from 6 AWG to 4/0 AWG, offering versatility for a wide range of wiring configurations. Its threaded design ensures a secure, vibration-resistant connection to conduit, making it ideal for applications requiring dependable grounding solutions. The bushing’s dimensions (8.5" length, 2" conduit entry diameter) align with standard industrial installations, providing compatibility with existing infrastructure. Commonly used in electrical distribution panels, motor control centers, and industrial machinery, this grounding bushing meets the demands of high-current applications where proper grounding is essential for equipment protection and personnel safety. The electro-zinc plating enhances durability in harsh conditions, including exposure to moisture, chemicals, and mechanical stress. Unlike non-insulated alternatives, the thermoplastic insulator prevents direct metal-to-metal contact, reducing the risk of electrical faults. Its robust construction and precise threading make it a practical choice for both new installations and retrofit projects in industrial, commercial, and utility applications.

How to Install Threaded Insulated Grounding Bushings

Complete installation guide for threaded insulated grounding bushings, exemplified by the 3870 Series. It covers threading the bushing onto conduit, securing it, and installing the bonding jumper. Specific instructions for catalog number 3999 are not provided in this document.

Estimated time: 15m

Tools needed:

Screwdriver, Torque wrench

Supplies needed:

Bonding jumper

  1. Thread Bushing onto Conduit

    Thread the insulated grounding bushing onto the conduit until it bottoms out. If needed, slightly back off the bushing to align the lay-in lug to the desired position.

  2. Secure Bushing with Set Screw

    Tighten the set screw to firmly secure the bushing onto the conduit. Ensure it is snug to prevent movement.

  3. Install Bonding Jumper and Torque

    Install the bonding jumper (not supplied) into the lay-in lug. Torque the wire clamping screw to the values specified in the provided torque table, considering the wire gauge and material (CU/AL).
