Overview

The NSi Industries 381 is a 1/2-inch insulated grounding bushing engineered from high-strength malleable iron, designed for secure termination of service conduit to cabinets, pull boxes, and junction boxes in electrical systems. Its locknut-type base ensures robust bonding and vibration resistance, preventing wire damage during installation while providing a smoothly rounded insulating surface for enhanced protection. The bushing features a grounding lug made from aluminum 6061-T6, enabling reliable bonding of jumpers to neutral busbars. A plastic metaliner safeguards wire insulation from abrasion and wear. The zinc-electroplated finish delivers superior corrosion resistance, extending durability in demanding environments. This component is rated for 150°C operation in trade sizes from 1/2" through 4", with 5" and 6" sizes rated for 105°C. The 381 is widely used in industrial, commercial, and residential electrical installations where dependable grounding and conductor protection are essential.
