Overview

The NSI Industries TL-38514 is a 1-1/2 inch threadless, insulated, grounding bushing constructed from durable malleable iron. Designed for secure and reliable grounding applications, this bushing features a 14-4 lug capacity, accommodating copper or aluminum ground wires from #14 AWG to #4 AWG. Its threadless design simplifies installation, eliminating the need to thread conduit and making it ideal for tight spaces, corners, and multiple conduit runs. The integral grounding lug ensures superior ground continuity and is designed not to fall off or get lost, simplifying installation compared to conventional bushings that require separate lug attachment. The bushing's mounting screw features a cone point for a secure grip on both threaded and non-threaded rigid conduits, enhanced by a nylon locking patch to resist loosening from vibration. The insulating nylon surface is rated for 150°C and features a rounded design to reduce wire pulling drag and prevent abrasion. This product conforms to UL 514B and UL 467 standards, ensuring compliance and safety. SKU: TL-38514.
