__size of wire__

__Cu__

18 AWG through 8 AWG 100 feet 100 feet

6 AWG through 1/0 AWG 200 feet 100 feet

2/0 AWG through 4/0 AWG 180 feet 80 feet

Now the problem is that the 18 thru 8 AWG is smaller than the 6 thru 1/0 AWG but the spacing is less. If you look at the table the spacing is progressively larger as the wire gauge becomes smaller. The spacing given as 100 feet is incorrect. It should be larger than 200 feet. Also, the spacing for the 6 thri 1/0 AWG for copper is the same as the 18 thru 8 AWG. The spacing given as 100 feet is incorrect because it is the same as the spacing given for the 18 thru 8 AWG which is smaller wire. It should read somewhere between 100 and 80 feet as given for the 2/0 thru 4/0 AWG wire. The numbers that I will propose will be 220 and 100 feet respectively.
