GRADED A+
⩥ The frequency of AC is measured in?
Answer: Measured in hertz Hz
⩥ What refers to a voltage can convey information?
Answer: Electrical Signal
⩥ What refers to the maximum voltage that can be reached by a signal?
Answer: Amplitude
⩥ Electricity may flow only when?
Answer: There has to be a for it to return making a complete circuit
⩥ What is the return path for electrical power to flow back to the service
panel?
Answer: Neutral
⩥ The live wire is always ungrounded?
,Answer: True. They are very hot caring electrical power
⩥ A ground electrode conductor originates at the neutral or equipment
ground bus of the service panel?
Answer: True
⩥ A ground electrode should not be made in contact with the earth?
Answer: False. sound be on contact with the earth
⩥ Compare Watts with Voltage
Answer: Watts are the measure of power. Voltage is the measure of
potential energy.
⩥ You should size conductors no less ______ of the continuous loads
plus _________ of the non-continuous loads,.
Answer: 125% / 100%
⩥ Conductor sizes are often expressed in?
Answer: American Wire Gage (AWG)

used?
Answer: True
⩥ RHH wires use rubber insulation that is high heat resistant and is good
in?
Answer: Is only good in dry locations.
⩥ RHW-2 wires use the rubber insulation but are suitable for wet
locations?
Answer: True
⩥ What cables can be used inside wall, ceiling or under the floor.
Answer: Non-metallic (NM)
⩥ What cables are most appropriate for damp areas?
Answer: Underground feeder (UF) or Non-metallic Wet underground
(NMWU)
⩥ THWN means?
Answer: Flame retardant, Heat resistant, Moisture resistant, Gasoline
resistant, and oil resistant.
, ⩥ An insulated grounded conductor which is ____ AWG or below
should be identified by a continuous white or gray outer finish.
Answer: 6 AWG
⩥ What is the amount of voltage measured between any two line
conductors of a balanced three-phase system.
Answer: Line voltage
⩥ What describes the voltage measured across any one component of a
balanced three-phase system.
Answer: Phase Voltage
⩥ A _______ is unintentional mess up.
Answer: Ground Fault
⩥ An effective Ground-Fault current path is?
Answer: An effective Ground-Fault current paths a path intentionally
constructed to facilitate the operation of the overcurrent protective
devices currently in place.
⩥ GFCI is never sensitive to small "leaks" of current
Answer: False. GFCI = ground-fault circuit interrupter
