Overview

NSI Industries L2N-141 is a high-conductivity copper compression lug designed for secure, low-resistance electrical terminations in industrial and commercial applications. Manufactured from premium copper tubing, this two-hole long barrel lug ensures reliable cable connections with a 600V rating and 90°C temperature tolerance. The tin-plated finish provides corrosion resistance and minimizes contact resistance, while the color-coded and die-indexed markings simplify installation and inspection. Listed under UL486A and UL467 (for 6 AWG–3/0 AWG), the L2N-141 supports applications up to 35KV when installed per manufacturer guidelines. The 5/8" mounting spacing and 1/4" bolt size accommodate standard hardware configurations, making it ideal for grounding and bonding systems in power distribution, renewable energy, and heavy machinery. The long barrel design allows for easy visual confirmation of full cable insertion, reducing installation errors and ensuring compliance with NEC standards. Compatible with Class B or C building wire copper cable, this lug delivers durable performance in high-current environments. The copper tubing construction ensures high conductivity, while the tin plating enhances durability and reduces oxidation over time. The die index and color coding provide clear identification for proper termination, and the two-hole configuration allows for secure mechanical fastening with a 1/4" bolt. The 5/8" mounting spacing is optimized for standard hardware, ensuring compatibility with a wide range of electrical enclosures and panels. With a maximum voltage rating of 35KV and a continuous rating of 600V, the L2N-141 is suitable for demanding applications in power systems, substations, and industrial machinery. The 90°C temperature rating ensures reliable operation in high-heat environments, and the cULus 486A/B listing confirms compliance with North American safety standards.
