NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q73-Q78):

NEW QUESTION # 73
Thebreaking capacityof a circuit breaker is typically expressed in:

Answer: B

Explanation:
Breaking capacity refers to the maximumfault currenta circuit breaker can safely interrupt and is expressed in amperes(often kA). NETA Level 2 technicians must verify breaker ratings during acceptance testing to ensure suitability for the available short-circuit current at the installation location.


NEW QUESTION # 74
What is theprimary purposeof the National Electrical Code (NEC)?

Answer: C

Explanation:
The NEC exists to providepractical safeguardsagainst electrical hazards that can cause injury, fire, or property damage. It is not a design manual, testing standard, or training guide, but a safety code intended to minimize risk through installation requirements.
NETA Level 2 technicians must understand that testing and commissioning activities support the NEC's safety intent. Verifying grounding, bonding, overcurrent protection, clearances, and labeling helps ensure installations meet the NEC's fundamental objective of protecting people and property from electrical hazards.


NEW QUESTION # 75
Harmonics in an electrical system increase the risk of fire and electric shock.

Answer: A

Explanation:
Harmonics cause increased heating in conductors, transformers, and neutral paths, which can degrade insulation and increase fire risk. They can also create unexpected voltage conditions and elevated touch potentials. NETA Level 2 technicians must recognize harmonic-related risks when evaluating system performance, especially in facilities with nonlinear loads such as VFDs and power electronics.


NEW QUESTION # 76
A piece of wire that is0.001 inchesin diameter and12 incheslong is defined as onemil-foot.

Answer: C

Explanation:
Amilis one-thousandth of an inch (0.001 in). Amil-footis a reference unit used in conductor resistance calculations. It describes a conductor that is1 mil in diameter and 1 foot long. Since 12 inches equals 1 foot, the statement is correct.
This unit supports standardized resistance formulas such as:
R = (K Γ— L) / CM
where R is resistance, K is the resistivity constant, L is length, and CM is circular mil area. While technicians in the field often rely on tables and software, NETA Level 2 fundamentals include understanding what these units represent so results and conductor resistance expectations can be sanity-checked.
This concept also appears when evaluating long cable runs, verifying conductor sizing, or interpreting low- resistance measurements where expected values are small and sensitive to length and cross-sectional area.


NEW QUESTION # 77
As frequency increases, theinductive reactanceof an inductor will:

Answer: A

Explanation:
Inductive reactance is defined as. As frequency increases, inductive reactance increases proportionally. This principle is essential for understanding AC circuit behavior, harmonic effects, and frequency-dependent impedance during testing and troubleshooting.


NEW QUESTION # 78
