Overview

The NSi Industries 385-14 is a malleable iron insulated grounding bushing designed for reliable electrical grounding and insulation in industrial conduit systems. This bushing features a 1 1/2-inch size and is configured with a 14-4 lug, accommodating copper or aluminum ground wires ranging from #14 AWG to #4 AWG. Its construction from malleable iron ensures durability. The integrated grounding lug provides enhanced ground continuity, and the insulating nylon surface is rated for 150°C, covering the top of the bushing and lug corners to reduce wire abrasion during pulling. The cone-point mounting screw with a nylon locking patch ensures a secure fit on both threaded and non-threaded rigid and IMC conduits. This design simplifies installation compared to traditional threaded bushings, especially in confined spaces, by eliminating the need to remove and reattach the grounding lug. The 385-14 is UL listed (File #E3060) and CSA certified (File #LR2884), conforming to UL 514B & UL 467 and CSA C22.2 No. 18 & CSA C22.2 No. 41 standards. Ideal for power distribution, industrial machinery, and electrical enclosures where robust grounding and insulation are critical.
