Arizona Contractor License CR-67 Exam
Questions with Detailed Verified Answers
Alternating Current (AC) Ans: AC always flows one way then the other.
Frequency of AC Ans: Measured in hertz Hz.
Electrical Signal Ans: Refers to a voltage that can convey information.
Amplitude Ans: Refers to the maximum voltage that can be reached by
a signal.
There is a return path for it making it a complete Circuit Ans: Electricity
may flow only when.
Neutral Ans: The return path for electrical power to flow back to the
service panel.
Live Wire/ Hot wire Ans: The _____ wire is always ungrounded and
carries electrical power.
Grounding Electrode Conductor Ans: Originates at the neutral or
equipment ground bus of the service panel.
False, It should always make contact with the earth Ans: A grounding
electrode should not be in contact with the earth.
Watts are the measure of power, Volts x Amps. Voltage is the measure of
potential energy. Ans: Compare watts with volts.

125% / 100% Ans: You should size conductors no less than ___ the
continuous loads plus ___ of the non-continuous loads.
American Wire Gage (AWG) Ans: Conductor sizes are often expressed
in _______________ (AWG).
Ampacity Ans: Refers to the allowable current-carrying capacity of a
conductor.
Insulation Type Ans: Determines the areas the wires can and cannot be
used.
RHH Wires Ans: Uses rubber insulation that is high heat resistant and is
only good in dry locations.
RHW-2 Wires Ans: Use rubber insulation but are suitable for wet
locations.
Non-metallic (NM) Cables Ans: Can be used inside wall, ceiling or under
the floor.
Underground Feeder (UF) Cables or Non-Metallic Wet Underground
(NMWU) Ans: Most appropriate for damp areas.
THWN Ans: Flame retardant, Heat resistant, Moisture resistant,
Gasoline resistant, and oil resistant.
6 AWG Ans: An insulated grounded conductor which is __ AWG or
below should be identified by a continuous white or gray outer finish.
Line Voltage Ans: The amount of voltage measured between any two
line conductors of a balanced three-phase system. (Phase to Phase)
Phase Voltage Ans: Describes the voltage measured across any one
component of a balanced three-phase system.
Ground Fault Ans: An unintentional mess up. (When a conductor is
shorted to ground)
