Answer the following statement(s) true (T) or false (F)
1. Many autotransformer starters contain taps that can be set for 50, 65, or 80 percent of the line voltage. 2. Wound rotor type motors and synchronous motors generally use autotransformer starters. 3. Most autotransformer starters use two transformers to reduce the voltage applied to the motor during the period of acceleration 4. Autotransformer starters provide greater starting torque per ampere drawn from the line than any other type of reduced voltage starter. 5. For closed transition starting, four separate start contactors are used.
