Bjarney That is a great question the stuff the office ordered was 19 strand and when I checked the job specs there was no requirement for the number of strands.
I just ordered some more and got 7 strand.
This is an addition to a building and the 3500' includes the original portion that I am adding to, the original is 19 strand 4/0 bare 10 years old, looks real bad.
It took a lot of wire brushing to get good material for cad welding.
