  • Product typeElectrical Connectors
  • Copper construction ensures high conductivity
  • Tin-plated finish resists corrosion for lasting connections
  • Rated for 600 V and 302 °F operation
  • Brazed long barrel adds mechanical strength
  • UL 467 listed for grounding and bonding

One-Hole Compression Lug for 8 AWG Wire

This Burndy YAD8CM10E38 lug accepts a single 8 AWG copper conductor with a 3/8 inch stud hole. The bare copper barrel has a tin finish and measures 0.31 inches long with a 0.26 inch outside diameter. It is rated for 600 volts and a maximum operating temperature of 302 degrees Fahrenheit.

Brazed Barrel Withstands Continuous Heat

The brazed barrel construction maintains mechanical integrity under sustained current up to the 600 volt rating. Tin-plated copper resists oxidation during long-term exposure to the maximum 302 degree Fahrenheit operating temperature. UL 467 listing confirms compliance for grounding and bonding applications under continuous load.

Crimp Installation Requires Correct Tool and Die

Installation uses a standard crimp termination on the long barrel. The 0.71 inch tongue width must align with the 3/8 inch stud for proper torque. Common issues include using an incorrect die size for 8 AWG or insufficient crimp pressure, which creates high resistance joints. Compatible Grainger references are 22P158, 22P219, and 22P221.

Questions about this item

How hot can the YAD8CM10E38 lug get during continuous operation?

The lug is rated for a maximum operating temperature of 302 Degrees F, so it handles sustained heat in heavy-duty circuits.

What crimp tool and wire size are needed to install this 3/8 in stud lug?

Use 8 AWG copper wire and a compatible crimp die for the 0.31 in barrel length and 0.26 in outside diameter.

Will the tin-plated copper barrel corrode when joined to older aluminium bus bars?

The contact finish is tin over copper; for aluminium connections use an antioxidant compound and follow UL 467 grounding practices.
