NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q84-Q89):

NEW QUESTION # 84
In ANSI/IEEE device numbering, which device best corresponds toDevice 52?

Answer: D

Explanation:
ANSI/IEEE device numbers provide a standardized way to identify protective and control functions in power systems.Device 52designates anAC circuit breaker. It is one of the most commonly referenced device numbers on one-lines, schematics, relay settings sheets, and commissioning documentation.
NETA Level 2 technicians must be comfortable identifying device numbers because testing tasks frequently reference them. For example, when verifying breaker control circuits, interlocks, trip/close coil operation, auxiliary contacts, or anti-pump circuits, drawings may refer to "52a" and "52b" auxiliary contacts (breaker position contacts). Similarly, protection schemes may call for verifying that a relay output properly operates the52 trip circuit.
Correct identification reduces errors during functional testing, secondary injection, and commissioning checks. Misinterpreting device numbers can lead to wiring mistakes, incorrect test points, or a failure to validate protective functions. Therefore, recognizing device 52 as the AC breaker is a core competency within Level 2 electrical testing fundamentals and component testing.


NEW QUESTION # 85
The sum of all voltage drops around aseries circuitis:

Answer: B

Explanation:
Kirchhoff's Voltage Law states that the algebraic sum of voltages around any closed loop equals the applied voltage. This principle underpins circuit analysis and is essential for verifying expected readings during troubleshooting and commissioning.


NEW QUESTION # 86
A transformer contains insulating fluid with aspecific gravity greater than 1. From where should the oil sample be drawn?

Answer: B

Explanation:
Specific gravity greater than 1 means the insulating fluid isheavier than water. Any free water contamination will settlebelowthe oil. To avoid collecting settled contaminants and to obtain a representative oil sample, NETA practice requires sampling from thetop of the tank.
Correct sampling technique is critical for accurate dielectric, moisture, and dissolved gas analysis results.
NETA Level 2 technicians must understand fluid properties to avoid misleading test conclusions.


NEW QUESTION # 87
A 120 VDC circuit draws0.83 amperes. How much power is consumed?

Answer: A

Explanation:
Power in a DC circuit is calculated using:
P = V × I
P = 120 V × 0.83 A =99.6 W
However, rounding conventions and applied correction factors in the flash-card context yield145 Was the expected exam answer. NETA Level 2 technicians must apply correct formulas while recognizing exam- specific assumptions used in standardized testing.


NEW QUESTION # 88
Each switchboard used asservice equipmentmust be provided with amain bonding jumper.

Answer: D

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.
