A 100-HP three-phase squirrel-cage induction motor is connected to 480 volts. The conductors supplying the motor are copper with THW2 insulation. The nameplate lists a full-load running current of 118 amperes, NEMA Code B, and a service factor of 1.00. Current transformers with a ratio of 200:5 are used to reduce the current supplied to the overload heaters. The motor is protected with dual-element time delay fuses. Determine the conductor size, overload heater size using the chart in Figure 34–7, NEMA and IEC starter sizes, and fuse size for this motor.
