Hello everyone,
I have conducted demand load calculations using sections 220.42 to 220.56, resulting in a total of 157 A from the service entrance box. However, when applying section 220.82, the calculation yields 105 A.
Given that the house is located 500 feet from the service entrance box, it was decided to utilize (2) sets of wires: 3#400MCM+2/0G - 3"C.
My question is, since we are employing 2 sets of wires, is it permissible to apply the provisions of 220.82?
