Notes:
1. These resistance values are valid only for the parameters as given. Using conductors having coated strands, different stranding type, and, especially, other temperatures changes the resistance.
2. Formula for temperature change:

3. Conductors with compact and compressed stranding have about 9 percent and 3 percent, respectively,
smaller bare conductor diameters than those shown.
