Overview

The NSi Industries 384-14 is a threaded insulated grounding bushing constructed from durable malleable iron, designed for reliable electrical grounding in industrial conduit systems. This bushing is specifically sized for 1 1/4-inch conduit and features a 14-4 lug connection, accommodating copper or aluminum ground wires ranging from #14 AWG to #4 AWG. Its integral grounding lug enhances ground continuity, ensuring a secure connection. The insulating nylon surface is rated for 150°C, providing protection for conductors and reducing wire-pulling drag. The cone-point mounting screw with a nylon locking patch ensures a secure grip on both threaded and non-threaded rigid and IMC conduits, resisting loosening from vibration. This design simplifies installation compared to conventional bushings, especially in tight spaces, as the lug is an integral part of the bushing. Manufactured in the USA, the 384-14 meets UL File #E3060 and CSA File #LR2884 standards, conforming to UL 514B & UL 467 and CSA C22.2 No. 18 & CSA C22.2 No. 41. Its robust construction and features make it an efficient and dependable grounding solution for power distribution, electrical panels, and industrial machinery.
