Copper Compression Lug

This 3M 30041 one-hole lug provides a copper compression connector for 3/0 AWG cable. The straight barrel design features a standard tongue with a 1/2 in stud size. Tin plating covers the copper body for corrosion resistance. A pack contains 10 pieces for multiple terminations.

For 3/0 AWG Copper Wire Terminations

Electricians and installers terminating 3/0 AWG copper conductors to a 1/2 in stud will find this lug matches the cable and hardware. The orange colour code and die code 14 identify the correct crimping tool setting. Buyers working with different cable sizes, aluminium conductors, or other stud diameters should select a different lug.

Short Barrel Length 2.63 in

The barrel length measures 2.63 in overall with a short barrel design. Width is .91 in and the hole centre to end distance is .531 in. No peep hole is present on this connector. Verify these dimensions fit the available space and crimping tool before purchase.

Questions about this item

How do I confirm the 30041 lug is seated correctly after crimping?

Check that the barrel is fully compressed around the 3/0 cable, the tin-plated copper surface shows no gaps, and the 1/2 in stud hole aligns with the 0.531 in centre-to-end dimension.

What comes in the package and what must I supply separately?

The box contains ten orange-coded copper lugs, die code 14, each 2.63 in long with a 0.91 in width; you must provide 3/0 AWG cable and a compatible crimping tool.

Which version should I choose if I need a peep hole for inspection?

This 30041 model has no peep hole; select a different 3M lug variant that lists a peep hole in its specifications.
