Which of the following is true about who may perform voltage measuring tasks on electrical equipment with an electrical hazard?

• A. Only qualified persons
• B. Anyone trained
• C. Only licensed electricians
• D. Only on de-energized equipment

Answer: (A)

Voltage measuring around equipment with a live electrical hazard is a task that requires a qualified person—someone who has received the right training, understands the hazards, and is authorized to perform the work. A qualified person can recognize arc-flash and shock risks, select and use the proper test instruments, apply the correct PPE, and follow safe work practices and procedures such as lockout/tagout. Being trained is important, but qualification also includes demonstrated competence and authorization to perform the task safely; it isn’t limited strictly to licensed electricians, since other workers who are properly trained and recognized as qualified can perform these tests. Measuring voltage on energized equipment is permissible for a qualified person when done with the correct equipment and precautions, and it isn’t restricted to de-energized equipment only.
