UPDATE 2025
The live wire is always ungrounded? - CORRECT ANSWER-True. They are very hot
caring electrical power
A ground electrode conductor originates at the neutral or equipment ground bus
of the service panel? - CORRECT ANSWER-True
A ground electrode should not make contact with the earth? - CORRECT ANSWER-
False
What is the difference between watts and voltage? - CORRECT ANSWER-Watts are
the measure of power. Voltage is the measure of potential energy.
You should size conductors no less ______ of the continuous loads plus
_________ of the non-continuous loads,. - CORRECT ANSWER-125% / 100%
Conductor sizes are often expressed using? - CORRECT ANSWER-American Wire Gage
(AWG)
,What refers to the allowable current-carrying capacity of a conductor? - CORRECT
ANSWER-Ampacity
The insulation type determines the areas where electrical wires can and cannot
used? - CORRECT ANSWER-Yes, the type of insulation on an electrical wire does
determine the environments where it can be safely used. Different insulation
materials are designed to withstand different conditions, such as moisture,
temperature, chemicals, and UV exposure.
Alternating Current (AC) always flows one way then the other? - CORRECT ANSWER-
True. AC always flows one way then the other.
The frequency of AC is measured in? - CORRECT ANSWER-Measured in hertz Hz
What refers to a voltage that can convey information? - CORRECT ANSWER-Electrical
Signal
What refers to the maximum voltage that can be reached by a signal? - CORRECT
ANSWER-Amplitude
Electricity may flow only when? - CORRECT ANSWER-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? -
CORRECT ANSWER-Neutral
, RHH wires use rubber insulation that is high heat resistant and is good in? -
CORRECT ANSWER-Suitable for dry locations
RHW-2 wires use the rubber insulation but are suitable for wet locations? -
CORRECT ANSWER-Yes, RHW-2 wires utilize rubber insulation and are specifically
designed for use in wet locations. The "W" in RHW-2 indicates moisture
resistance, making it suitable for environments where dampness or water
exposure is possible.
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-For damp
locations, cables like THW (Thermoplastic, Heat and Water Resistant), THWN
(Thermoplastic, Heat and Water Resistant), THWN-2 (Thermoplastic, Heat and
Water Resistant, with higher temperature rating), RHW (Rubber, Heat and Water
Resistant), and RHW-2 (Rubber, Heat and Water Resistant, with higher
temperature rating) are suitable. These cables are designed to withstand
moisture and are commonly used in environments with moderate degrees of
moisture
THWN means? - CORRECT ANSWER-T: Thermoplastic (refers to the insulation type).
H: High Heat-resistant.
W: Water-resistant.
N: Nylon-coated (refers to the outer protective layer).
