Overview

The NSi Industries 389-DC40 is a zinc die-cast insulated grounding bushing designed for reliable electrical grounding applications. This bushing is specifically sized for 3 1/2-inch conduit and accommodates a 6-250 AWG lug, ensuring secure connections for copper or aluminum conductors. Its insulated design provides protection for conductors entering raceways, pull boxes, and junction boxes, meeting National Electric Code requirements for safeguarding ungrounded conductors. The bushing features a rounded insulator surface to reduce wire drag and prevent abrasion during wire pulling, potentially reducing pulling effort. The integral grounding lug enhances ground continuity and is designed to accept a wide range of ground wire sizes, reducing inventory needs. The mounting screw is equipped with a cone point and nylon locking patch for a secure grip and resistance to loosening from vibration. Manufactured by NSi Industries, this bushing is built for durability in industrial settings. It 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. The insulator is rated for 150°C/302°F applications with a 94V-0 flammability rating.
  • Zinc die-cast construction for durability.
  • 3 1/2-inch conduit size with a 6-250 AWG lug capacity.
  • Insulated design protects conductors and meets NEC requirements.
  • 150°C rated insulator with 94V-0 flammability rating.
