When taking voltage measurements, for reasons of electrical safety, what should be the proper sequence of actions?
AI Explanation
The correct answer is B.
The proper sequence of actions when taking voltage measurements for electrical safety is:
1. Determine the nominal voltage from the nameplate or other documentation.
2. Select the proper personal protective equipment (PPE) and voltage tester based on the nominal voltage.
3. Proceed to take voltage measurements with confidence, having chosen the appropriate equipment.
This sequence is important because it ensures that the correct voltage tester and PPE are used for the given voltage levels, reducing the risk of electrical hazards. Measuring the actual voltage first (option A) does not provide the necessary information to select the proper equipment. Similarly, options C and D do not properly account for the need to identify the voltage level before taking measurements.
