Overview

The NSI Industries 383 (SKU 383) is a 1-inch insulated grounding bushing engineered for electrical installations requiring reliable conductor protection. Constructed from durable malleable iron, this bushing safeguards ungrounded conductors during wire pulling operations, reducing abrasion and preventing wire damage. Its smooth, rounded insulating surface minimizes friction, while the broad flange covers knockout holes to block debris ingress and maintain system integrity. High ribs enable secure hand or wrench tightening, ensuring a stable fit and reducing the risk of loosening over time. Compatible with grounding wire sizes from 10 SOL to 3/0 STR, the NSI 383 meets UL certification standards with a 105°C temperature rating, making it suitable for high-heat applications. Key dimensions include a height of 1.437 inches, a length of 2.320 inches, and a width of 0.748 inches, ensuring precise fitment in standard electrical enclosures. Manufactured in the US, this bushing is ideal for industrial, commercial, and utility applications where reliable grounding and conductor protection are critical.
