Answer / anupam mathur. cable size depends on 1)voltage drop, 2)distance, and 3)load so u have to calculate first the permissible voltage drop. for lighting circuit permissible voltage drop: * to calculate wire size, use 12.9 as your k for copper and 21.2 as your k for aluminum. * "l" is the one-way wire length in ft. * "r" is the resistance per 1,000 ft. use nec table 9 for ac wiring. if you have non-linear loads, use the column that helps account for power factor.
