Burndy Long Barrel Copper Lug

The Burndy long-barrel copper lug is a one-hole compression connector built for 2 AWG stranded copper wire. It carries a brown colour code and die code 10 with a straight tongue that measures .6 inches wide. The lug is CSA certified and listed to UL 486A-486B for commercial electrical installations.

Thermals and electrical ratings

Rated for a maximum operating temperature of 194 degrees F and a maximum voltage of 35 kV AC, the connector handles continuous load without an inspection hole. Copper construction provides low resistance and reliable current transfer under normal service conditions. The crimp termination style creates a secure joint that resists loosening over time.

Build integration

Designed for a 1/4 inch stud, the lug fits directly onto standard terminal posts without adapters. Its long barrel accommodates the full stripped length of 2 AWG conductor while the straight tongue keeps cable routing clean in panels or enclosures. The 2.600 inch overall length allows it to sit flush in tight wireways.

Questions about this item

How do I crimp the long-barrel lug onto 2 AWG copper wire and what step is often missed?

Strip the conductor to the full barrel depth, insert it until the insulation butts the barrel shoulder, then compress with a die-code-10 tool; the step often missed is verifying the crimp reaches the brown colour-code mark.

What maintenance or replacement will this lug need over time?

The copper lug itself requires no scheduled replacement; periodically inspect the crimp joint for corrosion or overheating and re-torque the 1/4 in stud hardware if it loosens.

What limit appears first during sustained high-current use?

The 194 °F maximum operating temperature is the first limit reached under continuous load before the 35 kV AC voltage rating becomes a concern.
