Overview

The NSI Industries L238 is a high-conductivity copper compression lug engineered for secure, long-lasting electrical connections in industrial and commercial power distribution systems. Manufactured from premium copper tubing and tin-plated for corrosion resistance, this lug delivers superior conductivity with low contact resistance, ensuring reliable performance in demanding environments. Designed for 2 AWG copper cable, the L238 features a long barrel design that increases surface area for a robust crimp, reducing the risk of pull-out and maintaining connection integrity over time. The 3/8" bolt size accommodates standard hardware, making it compatible with a wide range of industrial applications, including motor control centers, panel boards, and grounding systems. Key specifications include a temperature rating of 90°C and a maximum voltage rating of 600V, with listings for 35KV applications when installed per cable manufacturer instructions. It is color-coded (Brown for L238) and marked with die index information for easy identification and correct tooling during installation. The flared end of the barrel simplifies cable insertion, particularly for flexible and extra-flexible copper cables such as locomotive, welding, and mining cables. This design reduces pressure on cable strands, protecting them from chafing and breakage due to movement. The L238 is suitable for Class B or C building wire CU cable only, making it a dependable choice for critical power distribution and grounding systems where performance and durability are paramount.
