Assured Pass.
You should size conductors no less ______ of the continuous loads plus of the non-
continuous loads,.
125% / 100%
Conductor sizes are often expressed in?
American Wire Gage (AWG)
What refers to the allowable current-carrying capacity of a conductor?
Ampacity
The insulation type determines the areas the writers can and cannot used?
True
RHH wires use rubber insulation that is high heat resistant and is good in?
Is only good in dry locations.
RHW-2 wires use the rubber insulation but are suitable for wet locations?
True
,What cables can be used inside wall, ceiling or under the floor.
Non-metallic (NM)
What cables are most appropriate for damp areas?
Underground feeder (UF) or Non-metallic Wet underground (NMWU)
THWN means?
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.
6 AWG
What is the amount of voltage measured between any two line conductors of a
balanced three-phase system.
Line voltage
What describes the voltage measured across any one component of a balanced
three- phase system.
Phase Voltage
A _____ is unintentional mess up.
Ground Fault
,An effective Ground-Fault current path is?
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
False. GFCI = ground-fault circuit interrupter
Grounding and bonding means exactly the same thing?
False. Bonding is a means of allowing electrical continuity between metallic
objects.

minimum headroom of m.
2.0 m
typically there are_ hot wires running from the utility company into the service
panel.
2
A service disconnect need to have a rating which is?
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.
True
, System grounding is required when you have a supply transformer of a SOV or
lower system?
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.
Anything 16 AWG or lower
Class 1 signaling and remote control circuits are limited too?
600 Volts
When a circuit controls equipment can introduce a direct life safety hazard, the
circuit has to be?
Class 1
Class 2 circuit must be kept separate from lighting?
True
Generally, cables that are installed in ducts for environment air should be of what
type?
CL2P or CL3P
Cables installed in building locations other than in plenums for environmental air
may be?
CL2 or CL3
