Overview

NSI Industries L250NB is a UL486A-listed, two-hole long barrel copper compression lug engineered for 250 MCM flexible copper cables. Designed for demanding applications such as locomotive, welding, and mining cable installations, this lug features a gentle, continuous flared end that simplifies cable insertion for flexible and extra-flexible copper conductors. The flared design reduces pressure on cable strands post-installation, protecting them from chafing and breakage caused by cable movement. Tin-plated for enhanced corrosion resistance, the L250NB is rated for 600V and is exclusively compatible with copper cables. With a single mounting hole and NEMA-spaced mounting holes (1¾"), installation is streamlined. The lug is produced from high-conductivity copper tubing, ensuring reliable electrical performance. For expanded wire range compatibility, install with the NSI N12ID dieless compression tool. Temperature rated to 90°C, this lug meets UL486A and cULus 155027 standards, making it suitable for industrial and heavy-duty applications where durability and safety are critical.
