NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q56-Q61):

NEW QUESTION # 56
A delta-connected load has aphase impedance of 12 #and is supplied from a480 V line-to-line source. What is theline current?

Answer: D

Explanation:
For delta systems:
Phase voltage = Line voltage = 480 V
Phase current = V / Z = 480 / 12 = 40 A
Line current = #3 × Phase current
= 1.732 × 40 #69.3 A
NETA Level 2 technicians must correctly distinguish between phase and line quantities when evaluating three- phase systems, as incorrect assumptions frequently lead to misinterpreted test results.


NEW QUESTION # 57
When may anunqualified personenter theLimited Approach Boundary?

Answer: B

Explanation:
The Limited Approach Boundary defines the minimum distance from exposed energized parts that unqualified persons arenever permitted to cross. Entry into this space is restricted to qualified persons who understand the hazards and are trained to apply proper protective measures.
NETA safety objectives emphasize that escorting, PPE, or voltage level does not override qualification requirements. Only qualified individuals with appropriate training and authorization may enter the Limited Approach Boundary. This rule is foundational to preventing shock injuries and is strictly enforced during testing, inspection, and commissioning activities.


NEW QUESTION # 58
On an electrical schematic, adot on a current transformer symbolindicates:

Answer: B

Explanation:
The dot convention indicatespolarity, showing the instantaneous current direction relationship between primary and secondary windings. Correct polarity is critical for protection schemes, differential relays, and metering accuracy. NETA Level 2 technicians must verify CT polarity during installation and commissioning to ensure correct relay operation.


NEW QUESTION # 59
Using the provided diagram, what is thetotal circuit resistance?

Answer: A

Explanation:
Total circuit resistance depends on how resistors are connected. Based on the diagram referenced in the flash card, the combined series and parallel elements resolve to a total resistance of10 ohms.
NETA Level 2 technicians must be able to simplify basic resistor networks to verify expected readings during troubleshooting and test setup verification. Incorrect resistance expectations often point to wiring errors, short circuits, or incorrect test lead placement.


NEW QUESTION # 60
Each switchboard used asservice equipmentmust be provided with amain bonding jumper.

Answer: A

Explanation:
A main bonding jumper is required to connect the grounded conductor (neutral) to the equipment grounding conductor at the service disconnect. This establishes a low-impedance fault return path necessary for overcurrent devices to operate promptly. NETA Level 2 technicians must verify proper bonding during acceptance and maintenance inspections because improper bonding can lead to elevated touch potentials and ineffective fault clearing.
