Since there is too much voltage drop, work formula backwards to find Z the complex impedance of the wire needed for this voltage drop. Z(/ KFT = Vd = 7.2 V = .1164 (/ 1000’ ... For feeders sized for future capacity circuit breaker may be increased to the ampacity of the wire for future capacity, therefore, breaker could be sized at 150A. ................
