What is theRestricted Approach Boundaryfor a69 kVsystem?
- A. 1 ft 0 in
- B. 2 ft 2 in
- C. 6 ft 0 in
- D. 3 ft 10 in
Answer: D
Explanation:
Approach boundaries are central to electrical safety programs aligned with NFPA 70E concepts and the safe work practices expected of NETA technicians. TheRestricted Approach Boundaryrepresents the distance from an exposed energized conductor or circuit part where there is an increased likelihood of shock, requiring specialized training, PPE, and controls. Entry is tightly controlled and generally requires work planning, justification, and protection methods.
For a69 kVsystem, the target Restricted Approach Boundary in your flash cards is3 ft 10 in. This value is used in field safety planning to establish barricades, determine permissible proximity, and ensure that only qualified persons with appropriate protective measures enter that space.
NETA Level 2 technicians must be able to apply boundaries when setting up test areas, especially in switchyards and medium/high-voltage environments, where inadvertent approach can occur during lead placement, phasing, or instrument setup. Correct boundary application is not optional-it is a foundational requirement to prevent shock exposure.

- A. Cosine
- B. Sine
- C. Secant
- D. Tangent
Answer: B
Explanation:
Thesineof an angle is defined as the ratio of the opposite side to the hypotenuse. Trigonometry is used in power factor analysis, phasor relationships, impedance calculations, and AC circuit analysis. NETA Level 2 technicians must understand these relationships when evaluating voltage, current, and phase angles in testing scenarios.
NEW QUESTION # 28
Under what condition istagout without lockoutpermitted according to OSHA and NETA safety practices?
- A. When the energy isolating device is not capable of being locked
- B. When the system voltage is below 50 volts
- C. When the employee is continuously monitoring the equipment
- D. When a supervisor authorizes tagout only
Answer: A
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 # 29
Electrical equipment working space must have at least two entrances of sufficient area to permit access.
- A. True only above 600 V
- B. False unless the room is classified as a confined space
- C. False
- D. True
Answer: D
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.

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 # 31
A transformer contains insulating fluid with aspecific gravity greater than 1. From where should the oil sample be drawn?
- A. From the top of the tank
- B. From the middle of the tank
- C. From the conservator
- D. From the bottom of the tank
Answer: A
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 # 32
What is theprimary purposeof the National Electrical Code (NEC)?
- A. To regulate electrical worker training
- B. To establish utility interconnection rules
- C. To standardize electrical testing procedures
- D. The practical safeguarding of persons and property from electrical hazards
Answer: D
Explanation:
The NEC exists to providepractical safeguardsagainst electrical hazards that can cause injury, fire, or property damage. It is not a design manual, testing standard, or training guide, but a safety code intended to minimize risk through installation requirements.
NETA Level 2 technicians must understand that testing and commissioning activities support the NEC's safety intent. Verifying grounding, bonding, overcurrent protection, clearances, and labeling helps ensure installations meet the NEC's fundamental objective of protecting people and property from electrical hazards.
