4 AWG Long Compression Lug

This Burndy YAD4CM10E38 is a one-hole copper compression lug rated for a single 4 AWG conductor. It accepts a 3/8 inch stud and carries a 600 V maximum voltage rating with a 302 °F temperature limit. The tin-plated barrel is brazed for strength and measures 0.43 inches long with a 0.41 inch outside diameter. UL 467 listing confirms grounding and bonding compliance.

Installation Notes

Termination is by crimp only using tooling matched to 4 AWG copper and the long barrel length. The bare connector has no insulation, so heat-shrink or tape must be added after crimping if cover is required. A 0.71 inch tongue width fits the 3/8 inch stud cleanly, but verify stud clearance in the panel before committing. Mis-sized dies or insufficient crimp force are the most common causes of high resistance joints.

Who This Suits

Electricians and panel builders needing a UL-listed long-barrel lug for 4 AWG grounding or power distribution on 3/8 inch hardware. The tin finish resists corrosion in damp locations. Buyers who need an insulated lug, a two-hole mounting pattern, or a conductor size other than 4 AWG should look at a different part.

Questions about this item

How can I confirm the compression lug is crimped correctly after installation?

A properly crimped lug shows full barrel contact with the 4 AWG conductor, the 0.43 in barrel length is uniformly compressed, and the 3/8 in stud hole aligns cleanly with the mounting hardware.

What comes with the YAD4CM10E38 lug and what must I purchase separately?

The package includes the bare copper one-hole lug with tin finish, 0.71 in tongue width and brazed barrel; you must supply 4 AWG wire and an appropriate crimping tool.

Which stud size should I select for a 3/8 inch mounting bolt?

Choose the version with the 3/8 in stud designation, as it matches a 3/8 inch bolt and provides the correct hole clearance for secure termination.
