1 AWG Copper Compression Lug

The Zoro Select 24C353 is a one-hole compression lug built for 1 AWG stranded copper conductors. It suits electrical professionals and installers terminating heavy-gauge wire in panels, machinery or automotive systems. The seamless copper barrel and straight tongue provide a reliable crimp connection for power distribution tasks. UL listed and CSA certified, it meets recognised safety standards for industrial use.

Capacity and headroom for 1 AWG circuits

Rated for a maximum of 600 V AC and 300 degrees F, the lug handles standard low-voltage power circuits with adequate thermal margin. The barrel accepts only 1 AWG stranded copper, so there is no headroom for larger conductors; stepping up a wire size requires a different lug. The single 5/16 in stud hole limits mounting to one bolt pattern, and the short barrel keeps the overall length compact for tight enclosures.

5/16 in stud size decides fit

The critical specification is the 5/16 in stud hole, which must match the terminal or busbar bolt exactly. A mismatched stud size prevents secure mounting and risks a loose connection. The green colour code and die code 37 identify the correct crimping tool setting for a proper termination. Buyers needing a different bolt diameter or a two-hole mounting pattern cannot use this lug.

Questions about this item

Will this lug fit the 1 AWG copper cable I already have in my panel?

Yes — the barrel is sized for a single 1 AWG stranded copper conductor, minimum and maximum are both 1 AWG, so your existing cable matches exactly.

How can I verify the crimp is solid once I have installed the lug?

The connector has an inspection hole; after crimping you can look through it to confirm the wire is fully seated and the copper barrel is evenly compressed.

Does the package include the crimp die or any mounting hardware for the 5/16 in stud?

The lug itself is supplied; the green colour code and die code 37 tell you which die to use, and you will need to provide your own 5/16 in bolt, washer and nut.
