Product Identity

The Burndy YAD4CM8E516 is a one-hole compression lug built for 4 AWG copper conductors. It carries a 600 V rating and a 302 °F maximum operating temperature for demanding electrical and industrial wiring tasks.

Suitability

This lug suits installers who need a long-barrel, tin-plated copper connection on a 5/16 in stud. It is not for applications requiring smaller wire gauges, insulated barrels, or different stud diameters.

Installation Notes

Termination is by crimp using tooling matched to the .41 in barrel outside diameter and .43 in barrel length. The brazed barrel resists splitting, but incorrect die selection or an undersized crimp tool remains the most common cause of a poor joint.

Questions about this item

Which crimp tool die is required for the 4 AWG long barrel?

Use a die rated for 4 AWG with a 0.43 in barrel length and 0.41 in outside diameter to match the lug specifications.

Will the 0.63 in tongue width clear the bus bar on my existing 5/16 in stud terminals?

The tongue measures 0.63 in wide and fits a 5/16 in stud, so it aligns with standard terminals using that stud size.

How do I confirm the crimp meets the 600 V rating after installation?

Perform a pull-test per UL 467 and verify the tin-plated copper barrel shows no gaps or cracks along the 0.43 in length.
