NETA Level 2 Certified Assistant Electrical Testing Specialist Sample Questions (Q97-Q102):

NEW QUESTION # 97
Under what condition istagout without lockoutpermitted according to OSHA and NETA safety practices?

Answer: C

Explanation:
Lockout/tagout (LOTO) procedures are a fundamental safety requirement emphasized throughout NETA Level 2 objectives and OSHA 1910.147. Lockout is always the preferred method because it provides a physical restraintpreventing unexpected energization. However, OSHA permitstagout aloneonly under very limited circumstances. One such circumstance is when theenergy-isolating device is not capable of being locked, such as older disconnects or valves without lock provisions.
In these cases, tagout must be supplemented withadditional protective measuresto provide an equivalent level of safety. These measures may include removal of an isolating circuit element, blocking of a control switch, opening of an extra disconnecting device, or removal of fuses. Simply tagging equipment without addressing the lack of physical restraint is not acceptable.
NETA Level 2 technicians must understand that tagout doesnotprovide the same level of protection as lockout. Tags are warnings only and do not physically prevent operation. Therefore, tagout alone is never permitted merely for convenience, voltage level, or supervisory permission. The inability to lock the device is the critical condition that allows tagout to be used, and even then, only with additional safeguards in place.


NEW QUESTION # 98
Writethree thousand forty-eight ten-thousandthsin decimal form.

Answer: D

Explanation:
Ten-thousandths represent four decimal places. Three thousand forty-eight ten-thousandths equals:
3048 ÷ 10,000 =0.3048
NETA Level 2 technicians must be comfortable with decimal placement and numerical interpretation because testing instruments frequently display values in decimal form. Misplacing a decimal point can lead to serious errors when evaluating resistance, voltage, current, or insulation values.


NEW QUESTION # 99
What is meant by adead-tank circuit breaker?

Answer: A

Explanation:
Adead-tank circuit breakeris designed so that the interrupter assembly and associated operating components are contained within ametal tank that is bonded to ground potential. Because the enclosure is grounded ("dead"), the tank is not energized during normal operation. This construction reduces touch potential hazards and provides a robust, grounded barrier around interrupting components.
This contrasts with alive-tank breaker, where the external housing or tank is atline potential, requiring greater external clearances and insulation coordination. From a testing perspective, NETA Level 2 work commonly includes verifying breaker integrity through insulation resistance, contact resistance, functional checks, and in some applications, power factor testing or vacuum bottle integrity testing (depending on breaker type). Understanding "dead-tank" vs "live-tank" is important because it influences safe work practices, test lead placement, and interpretation of results (particularly for insulation-related tests and grounding considerations).
NETA objectives emphasize technicians being able to identify equipment construction types and apply the appropriate test approach and safety controls, especially regarding grounded enclosures, bonding, and the management of induced or stored energy.


NEW QUESTION # 100
Which instrument is used tolocate a fault in a 15 kV underground cable?

Answer: D

Explanation:
Atime-domain reflectometer (TDR)locates faults by measuring reflected signals caused by impedance discontinuities. NETA Level 2 technicians must recognize proper tools for underground cable diagnostics.


NEW QUESTION # 101
Using the provided diagram, what is thetotal circuit resistance?

Answer: B

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.
