Arizona contractor regulations applicable to contractors performing low-voltage
communication systems work. The Arizona Registrar of Contractors identifies CR-67 as the
dual commercial/residential classification covering the scopes of both C-67 Low Voltage
Communication Systems and R-67 Low Voltage Communication Systems

RHH wires use rubber insulation that is high heat resistant and is good in? - correct answer-Is only
good in dry locations.
RHW-2 wires use the rubber insulation but are suitable for wet locations? - correct answer-True
What cables can be used inside wall, ceiling or under the floor. - correct answer-Non-metallic (NM)
What cables are most appropriate for damp areas? - correct answer-Underground feeder (UF) or
Non-metallic Wet underground (NMWU)
THWN means? - correct 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. - correct answer-6 AWG

A _______ is unintentional mess up. - correct answer-Ground Fault
An effective Ground-Fault current path is? - correct 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 - correct answer-False. GFCI = ground-fault circuit
interrupter
Grounding and bonding means exactly the same thing? - correct answer-False. Bonding is a means of
allowing electrical continuity between metallic objects.

typically there are ____ hot wires running from the utility company into the service panel. - correct
answer-2
A service disconnect need to have a rating which is? - correct answer-No less than that the calculated
load or for the type of installation
Fast- blow fuses tend to open real quick when the rated current is reached. - correct answer-True
System grounding is required when you have a supply transformer of a SOV or lower system? -
correct answer-System grounding is required when you have a supply transformer of a 50V or lower
system which itself is supplied from a source over 150V to the ground
On a class 1 circuit it is ok to use smaller wire sizes than normal power circuits such as. - correct
answer-Anything 16 AWG or lower
Class 1 signaling and remote control circuits are limited too? - correct answer-600 Volts
When a circuit controls equipment can introduce a direct life safety hazard, the circuit has to be? -
