3081 has had good success with the KOP Burndy YAZV6CTC14FX lugs, using this procedure.

1. Carefully strip the #6 wire so that the bare wire is long enough to fully fill the barrel of the lug, and leaving about 2mm of bare wire showing between the lug and the insulation. You can tell that the barrel is completely full by looking through the inspection opening of the lug. Finally, inspect the insulation you removed to ensure that you did not cut any strands of wire off of the #6 wire. If so, try again.

2. Cut a piece of larger shrink tubing to cover the barrel end of the lug plus 1/2" of the wire. Slide that on the wire.

3. Slide the wire into the barrel of the lug. Ensure that there are no stray strands outside of the barrel.

4. Crimp the wire into the lug. We use Vice Grips to do this. It usually takes three passes of crimping before the wire is physically attached to the lug. You should crimp in the long direction of the barrel, in the middle of the barrel. If you can pull the lug off of the wire at this point, it is not crimped enough. Grab another lug and try again.

5. Using a high powered soldering iron or brazing torch, heat the lug in the middle of the barrel. We use a Weller WEL8200PK gun to do this.

6. Insert solder into the inspection opening of the lug, and load the inside of the lug with solder. You can easily put 12-18" of fine solder in the barrel.

7. Allow it to cool a bit.

8. Slide the shrink tubing into place and use a heat gun to shrink it.
