  • TypeElectrical Connectors
  • 4/0 AWG crimp connection for heavy-gauge power cables

  • UL 467 listed for grounding and bonding applications
  • Rated 600 V and 302 °F for demanding electrical systems

Terminal for 4/0 AWG cable

The Burndy YAD28M12E12 is an uninsulated compression terminal designed for 4/0 AWG copper conductors. It accepts a 1/2 inch stud and provides a tin-plated copper connection rated for 600 V. The brazed barrel construction ensures mechanical strength in demanding electrical and industrial wiring applications.

Replaces damaged or undersized lugs

This terminal replaces worn, corroded or incorrectly sized ring terminals on heavy-gauge cables. The jump is worth it when the existing lug shows heat damage, loose strands or a stud mismatch that cannot be resolved with a washer. UL 467 listing confirms compliance for grounding and bonding installations.

Verify stud size and crimp tooling

Confirm the mounting hardware uses a 1/2 inch stud before ordering. Ensure your crimp tool and die set are approved for 4/0 AWG long-barrel brazed terminals with a .89 in outside diameter. The bare copper finish requires antioxidant compound in corrosive environments.

Questions about this item

What stud size and barrel dimensions does the YAD28M12E12 terminal need for mounting?

It fits a 1/2 in stud and has a barrel outside diameter of .89 in, a barrel length of .87 in, and a tongue width of .95 in.

Which crimp tool and die are required for the 4/0 AWG barrel, and what common step is missed?

Use a Burndy tool with the correct die for 4/0 AWG long brazed barrel; the step often missed is fully seating the wire before crimping.

How can I tell when the tin-plated copper contact should be replaced?

Replace it if the tin finish shows heavy oxidation, the copper is discoloured above 302 Degrees F, or the barrel is cracked or deformed.
