Using the general resistivity formula, determine the most ideal wire gauge to be used in standard household appliances. The total power loss across the wire, in Watts, at maximum power output. 4 - Enter length of cable run required [power source to load]. The gauge of the wire is determined by the number of draws needed to produce wire of the desired size. We find a wire gauge for which the ampacity is higher than the fuse size (fuse size per owner's manual, otherwise we compute it as follows: fuse_size = load_current x 1.4). The voltage drop calculations are also based on a conventional load. Finding the exponent for 00, 000, and 0000 gauge wire is slightly different. Equation for calculate wire diameter in guage is, Wire Diameter in AWG = -10 - 20 × log (d) Where, d = Wire Diameter. Second - find 92 to the power calculated in the previous step.
