one way then the other.
The frequency of AC is measured in? - ANS Measured in hertz Hz
What refers to a voltage can convey information? - ANS Electrical Signal
What refers to the maximum voltage that can be reached by a signal? - ANS Amplitude
Electricity may flow only when? - ANS 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? - ANS Neutral

A ground electrode should not be made in contact with the earth? - ANS False. sound be on
contact with the earth
Compare Watts with Voltage - ANS Watts are the measure of power. Voltage is the measure
of potential energy.

What refers to the allowable current-carrying capacity of a conductor? - ANS Ampacity
The insulation type determines the areas the writers can and cannot used? - ANS True
RHH wires use rubber insulation that is high heat resistant and is good in? - ANS Is only good
in dry locations.
RHW-2 wires use the rubber insulation but are suitable for wet locations? - ANS True
What cables can be used inside wall, ceiling or under the floor. - ANS Non-metallic (NM)
What cables are most appropriate for damp areas? - ANS Underground feeder (UF) or Non-
metallic Wet underground (NMWU)

continuous white or gray outer finish. - ANS 6 AWG
What is the amount of voltage measured between any two line conductors of a balanced three-
phase system. - ANS Line voltage
What describes the voltage measured across any one component of a balanced three-phase
system. - ANS Phase Voltage
A _______ is unintentional mess up. - ANS Ground Fault
An effective Ground-Fault current path is? - ANS 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 - ANS False. GFCI = ground-fault circuit
interrupter
Grounding and bonding means exactly the same thing? - ANS False. Bonding is a means of
allowing electrical continuity between metallic objects.
A typical work space (for a working voltage under 600V) should have a minimum headroom of
______ m. - ANS 2.0 m
typically there are ____ hot wires running from the utility company into the service panel. -
