300 kcmil Copper Compression Lug

This one-hole lug accepts 300 kcmil stranded copper conductors and terminates on a 1/2 in stud. The seamless copper barrel carries a white colour code and die code 66 for crimp identification. UL listing confirms compliance with recognised safety standards. It suits electrical contractors and panel builders making permanent copper connections up to 35 kV.

Long Barrel Straight Tongue Layout

The long barrel provides extended crimp area while the straight tongue keeps the cable axis aligned with the stud. A 1.25 in tongue width matches standard bus-bar drilling patterns. No inspection hole is present so the crimp must be verified by die code or pull test. The lug fits single-conductor terminations where a single bolted connection is required.

257 °F Continuous Temperature Rating

Rated for 257 °F maximum operating temperature the lug maintains mechanical integrity under sustained load without derating. Seamless construction eliminates a potential split path during thermal cycling. Copper material ensures low resistance at the crimp interface over the service life. California Proposition 65 warnings apply to chemicals present in the product.

Questions about this item

What is the maximum operating temperature for the 24C333 compression lug?

The lug is rated for a maximum operating temperature of 257 Degrees F.

How much heat does the copper lug generate when conducting full load current all day?

Heat rise depends on the crimp quality and the ampacity of the 300 kcmil copper conductor, not on the lug alone.

What crimp tool and die are required to terminate this lug on 300 kcmil copper wire?

Use a die coded 66 (typically white colour code) matched to the long barrel and seamless copper construction.
