Compression Lug 400 kcmil 3/8 in Stud

This ZORO SELECT one-hole compression lug is built for terminating 400 kcmil stranded copper conductors in industrial and utility power circuits. The seamless copper barrel and straight tongue accept a 3/8 inch stud, providing a secure crimp connection rated for up to 35 kV. It carries a UL Listed mark and is intended for professional electrical installations.

Capacity and headroom

The lug handles a single 400 kcmil copper cable with no smaller or larger size range. Its 1.39 inch tongue width and long barrel give ample crimp area, while the 257 degrees F maximum operating temperature supports heavy continuous loads. The design has no inspection hole and one mounting hole, so it cannot accommodate multi-hole patterns or visual verification of conductor insertion.

Deciding specification

The fixed 400 kcmil conductor size is the critical parameter; the lug will not accept smaller or larger stranded copper wire. Buyers who need a different kcmil rating, a two-hole NEMA pattern, an inspection window, or an angled tongue must choose another part.

Questions about this item

Will the 400 kcmil barrel fit the copper cable I already have installed?

The lug accepts stranded copper wire sized exactly at 400 kcmil, so it matches cable of that same gauge.

How can I confirm the crimp is correct once I have installed the lug?

Use a die coded 76 with a compression tool; the seamless barrel and blue colour code indicate a proper crimp when the tool completes its cycle.

Does the package include mounting hardware for the 3/8 in stud or must I supply it separately?

The lug has a single 1.39 in wide tongue with one hole for a 3/8 in stud; bolts, washers and nuts are not included.
