In the basic 3-wire control circuit of a 3-phase AC induction motor that uses a full-voltage motor -starter, two individual PB switches are required.
The two individual PB switches must be wired in ___________________.
Continuous control-voltage or control power is normally applied to the ______________________ PB switch, which serves to interrupt the start or run condition of the motor.
The ______________________ PB switch, which serves to initiate a run condition of the motor, must be wired in parallel with a set of ______________________ auxiliary contacts on the motor -starter to seal in the start action.
A) parallel; NC Stop; NO Start; NO
B) series; NC Stop; NO Start; NC
C) series; NO Start; NC Stop; NO
D) parallel; NO Start; NC Stop; NO
E) parallel; NC Stop; NO Start; NC
F) series; NC Stop; NO Start; NO
