How to Install the Mighty-BOND™ Split Grounding/Bonding Bushing
This guide details the installation of the Mighty-BOND™ Split Grounding/Bonding Bushing, a UL Listed component for threaded Rigid or Intermediate Metal Conduit and fittings. Its unique split design allows for installation after conductors have been pulled, ensuring compliance with NEC Articles 250.64, 250.92, 344.46, and 300.4(G).
Estimated time: 15m
Tools needed:
Screwdriver
Supplies needed:
Grounding or bonding conductor
- Position the Bushing
Open the Mighty-Bond™ split bushing and carefully place it around the existing conductors. Position the bushing onto the threaded end of the Rigid Metal Conduit (RMC), Intermediate Metal Conduit (IMC), or fitting.
- Close and Align the Bushing
Ensure the set screw is backed out sufficiently. Close the Mighty-Bond™ bushing halves fully around the threaded conduit or fitting. Align the bushing to easily access the set screw, grounding lug, and hinge screw. Verify the bushing is seated as far down on the conduit or fitting threads as possible.
- Secure the Bushing
First, tighten the hinge screw. Then, tighten the set screw. If applicable, tighten the enclosure bonding screw. Ensure all these screws are tightened to the UL Torque requirement of 35 in-lb.
- Connect the Grounding Conductor
Insert the appropriately sized grounding or bonding conductor into the bushing's lug. Tighten the lug screw according to the UL Recommended torque specifications: 35 in-lb for 10-14 AWG Copper/10-12 AWG Aluminum, 40 in-lb for 8 AWG, 45 in-lb for 4-6 AWG, and 50 in-lb for 2/0-3 AWG.
