Overview

The NSI Industries SGBS-390CL is an insulated, grounding split bushing designed for efficient wire management in industrial applications. This steel bushing, with a 4-inch size, is specifically engineered to accommodate lugs ranging from 14 AWG to 1/0 AWG. A key advantage of the SGBS-390CL is its split design, allowing for installation after the wire pull is complete. This eliminates the common issues of burning through traditional bushings during wire pulling and the struggle associated with difficult puller maneuvers. By simplifying the installation process, this split bushing significantly saves time and reduces the physical effort required by technicians. Its robust steel construction ensures durability and reliable grounding, while the insulated feature provides an added layer of safety. The SGBS-390CL is a practical solution for electrical contractors and maintenance professionals seeking to streamline their installation workflows and enhance safety on job sites. Its compatibility with a range of wire sizes (14-1/0 AWG) makes it a versatile component for various electrical conduit and enclosure applications. The 4-inch diameter ensures a proper fit in standard industrial conduit systems.
  • Split design for post-wire pull installation
