3M 7000005882 Copper Two Hole Long Barrel Lug 500 Kcmil

Product Description

The 3M 7000005882 is a copper two-hole long barrel lug rated for use on copper conductors only, designed for high-voltage electrical terminations up to 35 kV. Constructed from one-piece, seamless, high-conductivity copper, this lug delivers reliable electrical continuity in demanding power distribution applications. It features a 1/2 inch stud size, a 0.836 inch inner diameter, and an overall length of 6.160 inches. The brown color coding corresponds to the 500 kcmil conductor size. Licensed electricians and electrical contractors working on medium-voltage systems will find this lug suited for both utility and commercial power termination work.

This lug is intended for copper conductor terminations in medium-voltage systems rated up to 35 kV. The long barrel design provides extended contact surface area, making it appropriate for high-current applications in switchgear, transformers, and distribution equipment. It is sold individually and is well-suited for commercial, industrial, and utility electrical installations where secure, low-resistance terminations are required.
