Size the branch circuit for an induction motor rated at 50 HP, three-phase, 60 Hz, 460 V, 1175 rpm, a service factor of 1.15, and a power factor of 90%. The motor is protected by time-delay fuses. Assume that the motor is out of sight of both the power supply and the controller (but the controller is within sight from the source). The nameplate full-load current rating of each motor is 70 A. Use THW (Cu) and EMT conduit.
