Burndy 4/0 AWG Compression Lug

The Burndy YAD28M10E38 is a one-hole copper compression lug rated for 4/0 AWG wire and a 3/8 inch stud. It is designed for electrical and industrial wiring applications requiring a secure crimp termination. The bare copper barrel has a tin finish and a brazed seam for reliable conductivity. This lug suits installers working on 600 volt maximum systems.

Long Barrel and Tin-Plated Copper

The long barrel style provides an extended crimp area measuring 0.87 inches in length with a 0.89 inch outside diameter. A tin-plated copper contact resists corrosion while the brazed barrel construction maintains mechanical integrity under load. The tongue width is 0.95 inches to fit the specified stud size. No insulation is included so the connection remains bare.

Verify Wire Size and Stud Compatibility

Confirm the conductor is exactly 4/0 AWG because the lug accepts no other wire gauge. Ensure the mounting hardware uses a 3/8 inch stud to match the tongue hole. Check that the operating environment stays within the 302 degree Fahrenheit temperature limit and 600 volt rating. The part carries UL 467 listing for grounding and bonding applications.

Questions about this item

Will the crimped joint on this 4/0 AWG lug need re-torquing or replacement over time?

The brazed-barrel, tin-plated copper lug is designed for a permanent crimp connection; no re-torquing is required once properly installed.

What is the first limit reached when this lug carries continuous heavy current?

The 600 V voltage rating and 302 °F maximum operating temperature define the electrical and thermal boundaries under sustained load.

How much heat does the lug generate when it runs all day at full load?

With a 0.95 in tongue width and 0.87 in barrel length, the copper body dissipates heat efficiently, staying within the 302 °F temperature rating during continuous operation.
