infinity Moderator Staff member Location New Jersey Occupation Journeyman Electrician Jan 28, 2007 #4 For the line side it would be 12.5% of the total the 5 parallel 500 kcmil conductors. So (2500 kcmil)(12.5%)=31250 kcmil, I don't have the book in front of me so it would be whatever size conductor 31,250 kcmil is.
