450 kcmil Copper Compression Lug

The Burndy YAD33M12E12 is a one-hole compression lug manufactured from electrolytic copper with a tin finish. It is designed for terminating 400 to 450 kcmil conductors in industrial and electrical installations. The lug accepts a maximum wire size of 450 kcmil and a minimum of 400 kcmil. It is rated for 600 V and a maximum operating temperature of 302 Degrees F.

Conductor Range 400-450 kcmil

The critical specification is the wire size range of 400 to 450 kcmil, which determines compatibility with the conductor being terminated. The barrel length measures 1.26 in with an outside diameter of 1.24 in and features a brazed barrel style. The tongue width is 1.5 in. This lug meets UL 467 standards for grounding and bonding applications.

Crimp Termination Requires Tooling

The termination style is crimp, meaning installation requires appropriate compression tooling and dies not included with the lug. The product ships as a bare connector with no insulation coverage or material. Compatible Grainger part numbers 22P219 and 22P221 reference related tooling or accessories. Buyers needing insulated terminals or screw-type connections must select a different product.
