Thomas & Betts BG150-14-20 Insulated Grounding Bushing

Description:

The Thomas & Betts Blackjack BG150-14-20 Insulated Grounding Bushing is used to provide equipment grounding and conductor protection on 1-1/2 inch rigid metal conduit (RMC) and intermediate metal conduit (IMC) systems. Commonly installed in industrial facilities, commercial buildings, power distribution systems, and electrical infrastructure projects, this grounding bushing ensures reliable grounding continuity while protecting conductors from abrasion. Maintenance teams and electrical contractors use this grounding bushing for repair, retrofit, expansion, and replacement of rigid conduit installations.

Applications:

The Thomas & Betts BG150-14-20 Blackjack Grounding Bushing is designed for threaded or threadless rigid and IMC conduit installations where equipment grounding and conductor protection are required. Its zinc-plated malleable iron body features an integral grounding lug that accepts copper or aluminum grounding conductors, while the molded nylon insulating throat reduces wire-pulling friction and helps prevent insulation damage. The design is particularly suited for industrial electrical rooms, switchgear, panelboards, motor control centers, and commercial conduit systems where dependable grounding and fast installation are essential.
