One-hole compression lug

The Burndy YAD36M20E34 is a copper compression lug designed for terminating large conductors in industrial and utility applications. It accepts wire sizes from 500 kcmil up to 600 kcmil and features a 3/4 inch stud hole for secure mounting.

Crimp termination limits

The lug uses a crimp termination style with a brazed barrel construction that is 1.38 inches long and has a 1.44 inch outside diameter. It is rated for a maximum voltage of 600 V and a maximum operating temperature of 302 degrees Fahrenheit, and it meets UL 467 standards for grounding and bonding.

Capacity and headroom

The 500 kcmil minimum wire size ensures a solid connection for heavy-gauge conductors, while the 600 kcmil maximum provides headroom for the upper end of this range. The long barrel style and tin-plated copper contact offer reliable conductivity, though the bare finish provides no insulation coverage for the termination point.

Questions about this item

Should I choose the 500 kcmil or 600 kcmil wire size for this lug?

The lug accepts wire from 500 kcmil up to 600 kcmil, so select the size that matches your actual conductor.

What does the 600 V rating mean once the lug is installed?

It indicates the maximum voltage the connection can safely carry in service, up to 600 V.

Does the 3/4 in stud size limit the bolt or hardware I can use?

Yes, the one-hole tongue is drilled for a 3/4 in stud, so the mounting bolt must match that diameter.
