  • TypeElectrical Connectors
  • Rated for 600 V maximum voltage

One-Hole Compression Lug 4/0 AWG 1/4 in Stud Long

This Burndy lug provides a single crimp termination for 4/0 AWG copper conductors in industrial and automotive power circuits. The long barrel design increases the crimp area for a secure mechanical bond on heavy-gauge wire. Tin-plated copper construction resists corrosion in harsh environments. It is rated for 600 V and continuous operation up to 302 Degrees F.

Who should use this and who should not

Electricians and technicians terminating 4/0 AWG cable to a 1/4 in stud on busbars, lugs or equipment pads will find the brazed barrel and UL 467 listing suitable for grounded connections. Installations requiring insulated barrels, right-angle tongues or multiple stud holes need a different connector style. Projects using smaller wire gauges or metric stud sizes cannot use this specific lug.

Critical specification: barrel length 0.87 in

The long barrel measures 0.87 in, which determines the required crimp die space and the number of crimps needed for a code-compliant joint. Verify that your crimping tool and die set accommodate this barrel length before purchase. Tongue width is 0.95 in and barrel outside diameter is 0.89 in for tool clearance checks.

Questions about this item

Will the tin-plated copper contact need re-plating after repeated thermal cycles up to 302 °F?

The tin finish on the copper barrel is rated for the full 302 °F operating temperature; no re-plating interval is specified by the manufacturer.

At 600 V continuous duty, does the 0.87 in brazed barrel reach its current limit before the 4/0 AWG conductor?

The long 0.87 in brazed barrel is sized for 4/0 AWG at 600 V, so the lug’s barrel is not the limiting factor under sustained load.

Does the bare copper lug run hotter than insulated terminals when crimped to 4/0 AWG and carrying full load all day?

With no insulation and a 0.95 in tongue, the lug dissipates heat directly; at the rated 302 °F maximum it remains within thermal limits during continuous operation.
