Overview

NSI Industries SGBS-39250 is a steel, insulated split grounding bushing designed for 6-inch trade size conduit with 350-500 MCM grounding lugs. The split design enables installation after wire pulling, eliminating the need to disassemble conduit systems during grounding applications. The insulated construction prevents galvanic corrosion between dissimilar metals while ensuring reliable electrical continuity. Compatible with large-diameter conduits, it simplifies grounding installations in industrial, commercial, and utility applications where 350-500 MCM conductors are specified. The 350-500 MCM lug accommodates standard grounding conductor sizes, reducing the need for additional adapters. Manufactured in the USA by NSI Industries, this code-compliant solution delivers durability and post-pull installation flexibility for grounding systems.

How to Install the Mighty-BOND™ Split Grounding and Bonding Bushing

This guide provides step-by-step instructions for installing the Mighty-BOND™ Split Grounding and Bonding Bushing onto threaded conduit or fittings.

Estimated time: 30m

Tools needed:

Screwdriver, Torque wrench

Supplies needed:

Mighty-BOND™ Split Grounding/Bonding Bushing, Grounding conductor

  1. Open and position the bushing

    Open the Mighty-BOND™ split bushing and place it around the conductors, positioning it onto the top of the threaded end of the Rigid or Intermediate Metal Conduit (RMC/IMC) or fitting.

  2. Close and align the bushing

    Close the Mighty-BOND™ bushing and ensure it is aligned to access the set screw, grounding lug, and hinge screw. Back out the set screw sufficiently to allow the two halves to close fully on the threaded conduit or fitting.

  3. Tighten screws

    Tighten the hinge screw first, followed by the set screw. If applicable, tighten the enclosure bonding screw. Ensure all screws are tightened to the UL Torque requirements of 35 in-lbs.

  4. Insert grounding conductor

    Insert the appropriate sized grounding or bonding conductor into the lug and tighten the screw according to the UL recommended torque specifications based on the wire size.
