Copper Compression Lug 350 kcmil

This ZORO SELECT compression lug accepts 350 kcmil stranded copper wire and terminates with a single 1/2 in stud hole. The seamless copper barrel carries a red colour code and die code 71. It is UL Listed for up to 35 kV and rated to a maximum operating temperature of 257 Degrees F.

Installers needing a long-barrel one-hole lug

The straight tongue measures 1.36 in wide and has no inspection hole. It suits copper conductors only and fits exactly one wire size. Buyers who need a two-hole pattern, an inspection window, or a different stud diameter should look at other lug styles.

Crimps into standard copper cable prep

A compatible crimp tool and the correct die are required to complete the termination. The long barrel provides extra contact length for high-amperage runs. No additional hardware is included with the lug itself.

Questions about this item

What wire size and material must I already have to use this 350 kcmil copper compression lug?

This lug is designed for stranded copper wire with a maximum size of 350 kcmil and a minimum size of 350 kcmil, so the conductor must match that exact gauge and material.

Will the 1/2 in stud hole on this lug fit the existing bolts on my bus bar or terminal block?

The lug features a single hole sized for a 1/2 in stud, so it will fit any matching 1/2 in bolt pattern on your existing bus bar or terminal block.

How can I verify the crimp is correct after installing this seamless copper lug?

Because the lug has no inspection hole, you confirm a proper crimp by using the correct die code 71 tool and verifying the red colour code matches the 350 kcmil specification.
