◉ What is the most common machine wire type?
Answer: THHN
◉ T/F: A three-wire controlled motor will restart automatically after
power is restored after a power failure.
Answer: False
◉ Jogging is a type of motor control in which what happens?
Answer: The motors rotation is moved (bumped) slightly.
◉ A wire's current carrying limit is known as what?
Answer: Ampacity
◉ A motor _______ is a motor controller that includes overload
protection.
Answer: Starter
,◉ If a switch is described by the term DPDT, what does this stand
for?
Answer: Dual pole, Dual Throw
◉ An interlock prevents two of the three phases on a reversing
motor from shorting by doing what?
Answer: Preventing the opposite coil from shutting it's contacts
when a coil is energized.
◉ Wire labelled THW means it has what characteristics?
Answer: Thermoplastic insulated, heat resistant, damp and wet
location.
◉ What is happening in the circuit when the fuse fails?
Answer: Too much current for too long.
◉ A wire's gauge is a measure of what?
Answer: The number of dies the wire was drawn through.
◉ How can you reverse motor direction?
Answer: Switch leads T1 and T3.
, ◉ What are the characteristics of a small diameter wire vs a large
diameter wire?
Answer: Small diameter wire has a smaller ampacity than large
diameter wire.
◉ The period of a given AC waveform is the time for one __________?
Answer: Full cycle
◉ Every digital multimeter can measure which three basic
elements?
Answer: Current, voltage, and resistance.
◉ If the voltage source supplies 260 volts and the resistance
measures 5 ohms, the current is what?
Answer: I = E/R -> I = 260/5 -> I= 52A
◉ In an AC circuit, if resistance remains the same and voltage is
doubled, the current...
Answer: Is doubled
◉ What aspect of a waveform does an oscilloscope display?
Answer: Voltage vs Time.
