  • TypeElectrical Connectors
  • Rated for 600 V maximum voltage

  • Long barrel design with 0.31 in barrel length
  • Tin-plated copper contact for corrosion resistance
  • UL 467 listed for grounding and bonding

One-Hole Compression Lug 8 AWG

This Burndy YAD8CM12E12 compression lug connects 8 AWG copper wire to a 1/2 inch stud. The tin-plated copper barrel accepts a single wire size and is rated for 600 volts at up to 302 degrees Fahrenheit. It suits industrial panels, automotive grounds and solar-array terminations where a single reliable crimp is required.

Replaces loose ring terminals or split bolts

The brazed long barrel (.31 in length, .26 in outside diameter) provides more crimp area than standard short barrels, reducing resistance on vibration-prone runs. Upgrade when existing lugs show heat discoloration or when a UL 467 listed connection is specified for grounding electrode conductors. The .87 inch tongue width fits standard 1/2 inch hardware without adapter washers.

Crimps with standard 8 AWG dies

Install with any UL-listed crimp tool matched to 8 AWG copper; no specialised dies are needed. The bare barrel has no insulation sleeve, so strip length must match the .31 inch barrel exactly — too long leaves exposed conductor, too short weakens the joint. Verify the tin finish is intact before crimping; oxidised barrels cause high-resistance connections that fail inspection.

Questions about this item

What stud diameter and barrel length does this lug need for mounting?

The lug has a 1/2 in stud hole and a .31 in barrel length, so the mounting hardware must match those dimensions.

How is the 8 AWG wire crimped into the brazed barrel, and what mistake should be avoided?

Use a UL 467 listed crimp tool sized for 8 AWG and the .26 in barrel OD; the common error is under-crimping, which leaves a loose connection.

When should the tin-plated copper lug be inspected or replaced?

Inspect after any over-temperature event above 302 Degrees F or if the tin finish shows corrosion; replace if the barrel is cracked or the stud hole is elongated.
