Overview

The NSi Industries 387-DC Insulated Grounding Bushing is a zinc die-cast component engineered for reliable electrical grounding in industrial and commercial systems. Designed for 2 1/2-inch conduit, this bushing features a 14-1/0 AWG lug connection, ensuring secure grounding for copper or aluminum wires. Its zinc die-cast construction delivers superior corrosion resistance and mechanical strength, ideal for harsh environments. The integral grounding lug eliminates loose parts, reducing installation time and inventory needs. The 150°C-rated nylon insulator covers the bushing and lug corners, preventing abrasion during wire pulling and meeting UL 514B and CSA C22.2 No. 41 standards. The cone-point mounting screw with nylon locking patch secures the bushing to both threaded and threadless rigid/IMC conduits, resisting vibration. This bushing supports wire ranges from #14 AWG to 4/0 AWG, reducing inventory by up to two-thirds. Certified by UL (File #E3060) and CSA (File #LR2884), the 387-DC is suitable for power distribution, industrial machinery, and electrical panels.
