Answer the following statement(s) true (T) or false (F)
1. Three-wire motor control circuits have three control circuit wires between the motor starter and the control device(s).
2. Permanent contact control devices are called-out as either normally open or normally closed.
3. Once the motor starter contactor is energized and closes the holding contacts, the holding contacts provide a redundant electrical path around the normally open Start pushbutton contacts, to keep the contactor control coil energized.
4. The normally closed Stop pushbutton is wired as the third control component in the ladder rung, so that it has master control over the entire rung.
5. Once the motor starter contactor control coil is energized, and being held energized by the holding contacts, pressing the normally closed Stop pushbutton will de-energize the control coil; causing the contactor holding contacts to open.
