Overview

The NSI Industries TL-382 is a 3/4-inch threadless insulated grounding bushing constructed from durable malleable iron, designed to protect ungrounded conductors at raceway, pull box, and junction box entrances. This bushing meets National Electric Code requirements for smoothly rounded insulating surfaces, ensuring conductor protection at critical connection points. The insulated throat liner reduces wire pulling effort by up to 50% compared to conventional bushings. Key specifications include a temperature rating of 105°C, compatibility with 14-4 AWG copper/aluminum wire, and suitability for rigid and intermediate metal conduit. The locknut-type base provides improved bonding and resists loosening under vibration. Conforming to UL 514B and CSA C22.2 No. 18 standards, the TL-382 is engineered for reliable grounding in industrial and commercial electrical systems. The threadless design eliminates conduit threading, simplifying installation and reducing labor time. The malleable iron construction ensures long-term durability in demanding environments.
