trip devices which of the following tests would be appropriate? Answer:
Determine long time delay
▶ 09 Answer: 09
▶ How many persons on the rescue team or service must hold a current
certification in CPR? Answer: at least one
▶ Analyze the circuit below. Assume that all switches are open initially and
then Sw. #1 is closed, in which state would the circuit be in? Answer:
Lamp #1 only is on.
▶ Which of the following is not a source of harmonics: Answer: pure
resistive loads
▶ Which of the following contact materials has the highest melting point?
Answer: tungsten
▶ Hard hats suitable for the performance of low voltage electrical work, but
NOT for higher voltage electrical work, are identified as being: Answer:
***Class G
▶ Which of the following would best describe a 59 device Answer:
Overvoltage
, ▶ Ventricular fibrillation occurs at currents as low as: Answer: 100mA -
2000mA
▶ When evaluating insulation test results on a medium-voltage, air-
magnetic circuit breaker, what quantity is evaluated? Answer: Watts-loss
???
▶ A differential relay acts on the principle of difference between which of
the following electrical quantities? Answer: all of the above (impedance,
voltage, and current)
▶ When it can be determined from the design of the circuit and the
overcurrent devices involved that the automatic operation of a device was
caused by an overload rather than a fault condition, no examination of the
circuit or connected equipment is needed before the circuit is reenergized.
Answer: True
▶ Which of the following would best describe a 87 device: Answer:
Differential
▶ If a single three-phase transformer of the proper ratings is not available,
three single-phase transformers can be connected to do the job. When this
is done, the connection is called a(n) Answer: three-phase bank
▶ To what does anti-pump refer? Answer: The circuit breaker can only be
closed once for an operation of the control switch to the close position
▶ Most transformer cores are not made from a solid piece of metal.
Instead, they are assembled from many thin sheets of metal. This type of
construction is called Answer: laminated
▶ The amount of current that flows into a transformer primary when voltage
is first applied is called _____ current. Answer: inrush
▶ Capacitance is directly proportional to the area of the plates. Answer:
True
▶ Under normal operating conditions, what charging state is your battery
charger set to? Answer: float
