Burndy 1 AWG Copper Lug

The Burndy YAD1CM16E58 is a one-hole compression lug made from electrolytic copper with a tin finish. It accepts a single 1 AWG conductor and is rated for 600 V at temperatures up to 302 °F. The brazed barrel measures 0.63 in long with a 0.57 in outside diameter. UL 467 listed for grounding and bonding applications.

Who should use this connector

Electricians and panel builders terminating 1 AWG copper wire in grounded systems will find this lug fits the spec. It is not suited for installations requiring insulated barrels, multi-hole mounting, or wire gauges larger or smaller than 1 AWG. Buyers needing a different stud size or barrel length should look at other listings.

Check before ordering

Verify that your crimp tool and die set match the long brazed barrel dimensions shown. Confirm the 1.1 in tongue width clears the mounting surface and that the single-hole pattern matches the busbar or terminal block. Ensure the 600 V rating and 302 °F temperature limit satisfy the circuit requirements.

Questions about this item

What crimp tool and die size are needed for the 1 AWG barrel on this lug?

Use a hydraulic crimper with a die that matches the 0.57 in barrel outside diameter and 0.63 in barrel length for a proper 1 AWG compression.

Can this tin-plated copper lug connect to an existing aluminium bus bar?

Apply an antioxidant joint compound between the tin-plated copper tongue and the aluminium bar to prevent galvanic corrosion.

How do I verify the crimp meets the 600 V UL 467 rating after installation?

Inspect for a uniform, flash-free crimp, then perform a pull test to confirm the 1 AWG conductor is held securely within the brazed barrel.
