About:
A 400 MCM One Hole Copper Long Barrel Compression Lug With 5/8 Stud is a heavy-duty electrical connector used to securely terminate large copper conductors to equipment, bus bars, or other hardware using a single 5/8-inch stud or bolt.
Its made from high-conductivity copper and has a long barrel to accommodate a deep cable insertion for strong mechanical and electrical connection.
This type of lug is installed by crimping the conductor into the barrel, forming a permanent, vibration-resistant joint commonly used in power distribution, grounding, and industrial electrical systems.
