One-Hole Compression Lug for 1/0 AWG Copper

This copper compression lug accepts a single 1/0 AWG stranded copper conductor. It features a 5/16 inch stud hole and a long barrel design for secure terminations in electrical panels or industrial equipment. The seamless barrel construction and straight tongue angle support reliable crimp connections. It is UL listed and CSA certified for 600 V AC maximum voltage.

Fits 5/16 in Stud and Long Barrel Requirements

The lug mounts on a 5/16 inch stud and the long barrel provides extended crimp engagement area. Its pink colour code and die code 42 identify the correct crimping tool settings for installers. The 0.75 inch tongue width fits standard terminal spacing without modification. No inspection hole is present, so visual verification of wire insertion must occur before crimping.

Rated 300 Degrees F for Sustained Operation

The connector withstands continuous operating temperatures up to 300 degrees Fahrenheit without degradation. Copper material maintains conductivity under prolonged thermal cycling in motor leads or power distribution blocks. The seamless seam style eliminates a potential split path during high-current heating and cooling cycles. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

How much current can the lug carry continuously before the 300 °F temperature limit is reached?

The lug is rated for a maximum operating temperature of 300 °F; continuous current must stay within the ampacity tables for 1/0 AWG copper at that temperature.

Does the copper lug run hot or require extra cooling when crimped to 1/0 AWG wire under full 600 V load all day?

The seamless copper barrel and 300 °F rating are designed for sustained 600 V operation without additional cooling when properly crimped.

Which crimp die must I already own to terminate this lug on 1/0 AWG stranded copper?

The lug carries die code 42, so a die set matching code 42 for 1/0 AWG is required for a proper crimp.
