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
Grounding and bonding means exactly the same thing? - ANSWER-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. - ANSWER-2.0 m
typically there are ____ hot wires running from the utility company into the service
panel. - ANSWER-2
A service disconnect need to have a rating which is? - 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. -
ANSWER-True
System grounding is required when you have a supply transformer of a SOV or
lower system? - 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. - ANSWER-Anything 16 AWG or lower
, Class 1 signaling and remote control circuits are limited too? - ANSWER-600
Volts
When a circuit controls equipment can introduce a direct life safety hazard, the
circuit has to be? - ANSWER-Class 1
Class 2 circuit must be kept separate from lighting? - ANSWER-True
Generally, cables that are installed in ducts for environment air should be of what
type? - ANSWER-CL2P or CL3P
Cables installed in building locations other than in plenums for environmental air
may be? - ANSWER-CL2 or CL3
Voltage drop can be calculated based on? - ANSWER-Voltage drop = (2) x (the
circuit length in ft) x (resistance per 1 ft) x (current)
Class 2 circuits. - ANSWER-Class 2 circuits may not be derived from a large
transformer by using fuses.
The pulling tension in pounds for a copper wire should not exceed how many times
the circular mil area of a conductor? - ANSWER-.008 mil
The breaking capacity specifies. - ANSWER-maximum current the fuse can handle
_____ occurs when there are two points in the circuit accidentally coming in
contact. - ANSWER-Short circuit
