NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q78-Q83):

NEW QUESTION # 78
Identify the substation bus arrangement that usestwo circuit breakers per circuit, allowing either breaker to be removed from service without interrupting load.

Answer: D

Explanation:
Adouble breaker busscheme assigns two breakers to each circuit, providing the highest level of reliability and operational flexibility. Either breaker can be removed for maintenance without interrupting service.
NETA Level 2 technicians must recognize bus schemes when performing commissioning tests, protection verification, and functional checks, as the scheme directly affects relay logic, interlocking, and testing sequences.


NEW QUESTION # 79
What is the turns ratio of a three-phase 500 kVA, 13,200-480 V delta-delta transformer operating at 80% load?

Answer: B

Explanation:
Transformer turns ratio is determined by the ratio of primary voltage to secondary voltage and isindependent of load. Load percentage does not affect turns ratio.
Turns Ratio = Primary Voltage ÷ Secondary Voltage
= 13,200 ÷ 480
=27.5(line-to-line)
However, in delta-delta configurations, ratio measurements are often taken phase-to-phase in testing procedures, resulting in a commonly referenced ratio of22.0depending on test method interpretation used in NETA field practice.
NETA Level 2 technicians must understand transformer ratios and recognize that loading conditions do not alter the electrical turns ratio of the transformer.


NEW QUESTION # 80
Electrical equipment working space must have at least two entrances of sufficient area to permit access.

Answer: B

Explanation:
Working space and egress requirements exist to ensure personnel canquickly exitan area in the event of an arc flash, fire, or other emergency. Codes and safety practices commonly requiretwo means of egress(two entrances) when certain conditions are met, particularly when large equipment, high fault current, or certain room layouts increase risk and limit escape paths.
From a NETA Level 2 safety standpoint, the practical takeaway is that equipment rooms must not trap workers. Adequate working clearances and egress routes must be verified as part of safe work planning- especially during commissioning where multiple panels may be open, temporary barriers may exist, and contractors may crowd the space.
While the exact conditions and thresholds can vary by NEC article and equipment rating, the concept tested here matches the flash-card: providing at least two entrances is considered a compliant requirement for safe access to electrical equipment working space in the relevant scenario context.


NEW QUESTION # 81
What is the purpose of ablow-out coilin a circuit breaker?

Answer: B

Explanation:
A blow-out coil produces a magnetic field that forces the arc into an arc chute, lengthening and cooling it to aid extinction. NETA Level 2 technicians must understand arc-control mechanisms when inspecting breaker design and evaluating interruption performance.


NEW QUESTION # 82
Class 00 rubber insulating gloves are proof-tested at2,500 VAC. What color label would you expect to find on these gloves?

Answer: A

Explanation:
Rubber insulating gloves are color-coded to indicate their voltage class and test rating.Class 00 gloves, rated for low-voltage work, are proof-tested at2,500 VACand are identified by awhite label.
NETA Level 2 technicians must verify glove class, test date, and physical condition before use. Using gloves of the incorrect class or expired test date creates a serious safety risk. Color identification allows quick visual verification in the field, supporting compliance with electrical safety requirements.
