When visiting a site with a Level I, Class II hazard, you should first consult
- A.
National Electric Code (NEC)
- B.
Uniform Building Code (UBC)
- C.
National Electric Safety Code (NESC)
- D.
Los Angeles Building Code
Correct Answer
C. National Electric Safety Code (NESC)Explanation
When visiting a site with a Level I, Class II hazard, the National Electric Safety Code (NESC) should be consulted. The NESC provides guidelines and regulations for the safe installation, operation, and maintenance of electric supply and communication lines. It specifically addresses safety measures for electrical hazards, including those associated with Level I, Class II hazards. The NEC focuses on electrical installations within buildings, while the UBC and Los Angeles Building Code pertain to general building construction and safety regulations. Therefore, the NESC is the most relevant code to consult in this scenario.Rate this question:

Two transformers A&B are paralleled on the primary and secondary side. An Electircal worker pulls out the fuses on the primary lines of the transformer B. Which part is considered dead?
- A.
Primary on A
- B.
Secondary on B
- C.
Lead lines between fuses and primary on B
- D.
None of the above
Correct Answer
D. None of the aboveExplanation
When the fuses on the primary lines of transformer B are pulled out, it means that there is no power supply to the primary side of transformer B. However, transformer A is still connected and functioning properly. Therefore, the primary on A is not considered dead. Similarly, the secondary on transformer B and the lead lines between the fuses and the primary on transformer B are also not considered dead because they are still connected to transformer A, which is still operational. Hence, the correct answer is "None of the above".Rate this question:

- D.
Work is never prohibited on an energized line
Correct Answer
D. Work is never prohibited on an energized lineExplanation
The correct answer is that work is never prohibited on an energized line. This means that regardless of the circumstances or conditions, it is always allowed to perform work on an energized underground 5kV line. This may be due to the fact that the necessary safety measures and precautions have been put in place to ensure the safety of the workers. It is important to note, however, that working on energized lines can be dangerous and should only be done by trained professionals who follow proper safety protocols.Rate this question:

In a large rotating motor the DC winding should be grounded to the frame for at least 10 minutes prioir to measuring the rotor resistance with a megaohmeter to avoid?
- A.
Injury to the employee
- B.
To eliminate the possibility of any stored charge in the rotor
- C.
To measure winding resistance
- D.
To protect the megaohmeter
Correct Answer
A. Injury to the employeeExplanation
In a large rotating motor, grounding the DC winding to the frame for at least 10 minutes prior to measuring the rotor resistance with a megaohmmeter is done to eliminate the possibility of any stored charge in the rotor. This is important to avoid injury to the employee who is conducting the measurement. If there is a stored charge in the rotor, it can pose a risk of electric shock when the resistance is measured. By grounding the DC winding, any stored charge is discharged, ensuring the safety of the employee during the measurement process.Rate this question:

The primary of a current transformer is energized. Why do you short circuit the secondary before servicing it?
- A.
The small induced flux will cause high voltage
- B.
To ensure safety to personnel
- C.
To prevent damage to the equipment
- D.
To prevent arching
Correct Answer
B. To ensure safety to personnelExplanation
To ensure safety to personnel, the secondary of a current transformer should be short-circuited before servicing it. This is because when the primary is energized, there is a small induced flux that can cause high voltage in the secondary. By short-circuiting the secondary, any potential high voltage is safely discharged, minimizing the risk of electrical shock or harm to the personnel working on the transformer.Rate this question:
