Burndy 4/0 AWG Copper Compression Lug

This copper compression lug is built for 4/0 AWG stranded copper conductors in commercial electrical installations. It provides a crimp termination with a straight tongue and a single 3/8 inch stud hole. The barrel carries a purple color code and die code 15 for tool selection. UL and CSA certifications confirm compliance with UL 486A-486B standards.

Capacity and headroom for 4/0 AWG copper

The lug accepts a single conductor size of 4/0 AWG with no range above or below that gauge. It is rated for a maximum operating temperature of 194 degrees Fahrenheit and a maximum voltage of 35 kV. An inspection hole allows visual verification of full conductor insertion before energising the circuit. These limits define the safe operating envelope for the termination.

Deciding specification: 1.02 inch tongue width

The tongue width of 1.02 inches and overall length of 2.300 inches determine whether the lug fits the busbar spacing and enclosure clearances in your panel. The straight tongue angle and single hole pattern must match the mounting layout. Verify these dimensions against your design drawings before specifying this part.

Questions about this item

Will this 4/0 AWG copper lug fit the existing 3/8 in stud on my bus bar?

Yes, the lug is drilled for a 3/8 in stud and the tongue width is 1.02 in, so it matches that hole pattern directly.

How can I confirm the crimp is correct after installation?

The barrel has an inspection hole; after crimping with a die code 15 tool you should see the conductor through that hole to verify full insertion.

Does the package include the crimp die or heat-shrink tubing?

Only the copper compression lug is supplied; the die code 15 crimp die and any insulation or heat-shrink must be purchased separately.
