Answer the following questions about a 460-V D-connected two-pole 100-hp 60-Hz starting code letter F induction motor:
(a) What is the maximum current starting current that this machine's controller must be designed to handle?
(b) If the controller is designed to switch the stator windings from a D connection to a Y connection during starting, what is the maximum starting current that the controller must be designed to handle?
(c) If a 1.25:1 step-down autotransformer starter is used during starting, what is the maximum starting current that it must be designed to handle?
