NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q47-Q52):

NEW QUESTION # 47
When measuring voltage using a multirange voltmeter, which range should be selectedfirst?

Answer: B

Explanation:
Best practice dictates starting on thehighest voltage rangeto protect the instrument and the user from unexpected overvoltage conditions. Once the approximate voltage is known, the range can be reduced to improve measurement resolution. This practice is fundamental to safe testing and is expected knowledge for NETA Level 2 technicians working around energized systems.


NEW QUESTION # 48
When personnel are working in apermitted confined space, how many attendants must remain outside the space and for how long?

Answer: A

Explanation:
Confined space safety requirements mandate thatat least one trained attendantremain outside the spacefor the entire duration of the entry operation. The attendant monitors conditions, maintains communication, and initiates rescue procedures if needed. NETA Level 2 technicians must comply with confined space protocols when testing transformers, vaults, or enclosed switchgear compartments.


NEW QUESTION # 49
Thebreaking capacityof a circuit breaker is typically expressed in:

Answer: C

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 # 50
An induction motor has a 40 kVA input, a power factor of 0.82, and an efficiency of 92%. What is the approximate output horsepower?

Answer: A

Explanation:
To calculate motor horsepower, real power must first be determined. Real power (kW) is calculated by multiplying apparent power (kVA) by power factor:
Real Power = 40 kVA × 0.82 = 32.8 kW
Next, efficiency must be applied to determine output power:
Output Power = 32.8 kW × 0.92 = 30.176 kW
Horsepower is calculated by converting kilowatts to horsepower using the conversion factor:
1 HP # 0.746 kW
Horsepower = 30.176 ÷ 0.746 #30.2 HP
NETA Level 2 technicians are expected to understand power relationships, including apparent power, real power, power factor, and efficiency. These calculations are commonly used when evaluating motor performance, loading conditions, and acceptance testing results.


NEW QUESTION # 51
Which terminal set would you expect to find on adigital low-resistance ohmmeter (DLRO)?

Answer: B

Explanation:
DLROs use a four-wire (Kelvin) connection: two current terminals (C1, C2) and two potential terminals (P1, P2). This arrangement eliminates lead and contact resistance from measurements, ensuring accurate low- resistance readings for bolted joints, bus bars, and grounding connections.
