Question 9Electricity & Electronics - 1st Asst/Chief

The correct answer is B) At the point of contact where the work will take place. When performing an absence-of-voltage test before commencing repair work, it is essential to check for the absence of voltage at the specific point where the work will be conducted. This ensures that the worker is not exposed to any live electrical circuits, which is a critical safety measure. Checking the voltage at the main feeder circuit breaker, the load side disconnect switch, or the source disconnect branch circuit breaker does not provide the necessary confirmation that the work area is de-energized. The absence-of-voltage test must be performed at the point of contact where the repair work will take place to ensure the safety of the worker.
