The 3 PK Burndy (YA39-2N) Cu Compression 2-Hole Lugs are designed for use with 750 kcmil copper cables in high-current electrical systems. These lugs feature a 1/2" stud size and 1-3/4" hole spacing, ensuring compatibility with a range of terminals and equipment. To use, strip the insulation from the cable, then insert the wire into the long barrel of the lug, ensuring a proper fit. Next, use a compression tool to crimp the lug onto the wire, creating a strong, solderless connection that is both secure and reliable. These compression lugs are perfect for industrial, commercial, and power distribution applications where durability and high conductivity are essential.
