Q: When calculating the service factor to find max amps of a motor you should _______?
- multiply volts times the SF
- multiply amps times the SF
- Divide amps by SF
- Divide SF by the line voltage
A: multiply amps times the SF

Q: It's important to protect a motor from excessive current to avoid _______
- unpredictable behavior
- Blown motor
- Fire
- A and B
- B and C
A: B and C

Q: What are two things you need to consider when sizing thermal protectors.
- rated current value at full load and maximum temperature it can operate
- number of fuses and overloads
- amp rating and pulley sizes
- weight of product and speed of motor
A: rated current value at full load and maximum temperature it can operate

Q: Which of the following conditions does not cause excessive current flow through the motor, control circuitry, and their conductors?
- Overloads
- Short curcuits
- Single phasing
- an undersized load
A: an undersized load

Q: A prolonged overload means what?
- the motor waits to burn up
- driving to heavy of load for an extended period of time
- not enough power to the motor
- a and c
A: driving to heavy of load for an extended period of time

Q: A ____ prevents the motor from being damaged.
- overload
- thermal protectors
- resistor
- fuse
- capacitor
A: overload
