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.

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
