Re: motor control questions on experior
Most exam questions that I have seen on motor controls involve a drawing of a fairly basic motor control diagram.
The diagram will show all the contacts, overloads, relays, signal lights, switches, etc...
Each of these locations will be given a corresponding number. You will then be given a few questions regarding this drawing and the sequence of events for operation.
Here are a few non-diagram type common questions:
1. A "stop" switch will be wired in ______ with the control circuit?
a. series b. parallel c. multiwire d. the overload relays
2. What type of control circuit must be restarted in the event of an interrupted power source?
a. two-wire b. three-wire c. continuous d. reactor type
3. The term "NC" represents what type of switch or contact?
a. no contact b. nice coil c. never close d. normally closed
