Who shall use test equipment to test circuit elements and verify deenergization?

• A. Maintenance technician
• B. Qualified
• C. Trainee
• D. Supervisor

Answer: (B)

The key rule is that testing equipment to verify deenergization must be used by a qualified person. This means someone who has demonstrated the necessary training and knowledge to recognize electrical hazards, select and apply the correct test instruments, and interpret the readings safely. Verifying that a circuit is deenergized is not just about turning a knob; it requires understanding which points to test, how to test for voltage with the right tool, and what steps to take if voltage is present. A qualified person has that level of capability, ensuring work can proceed without exposing themselves or others to shock or arc flash. A trainee lacks the required training, and a supervisor, while able to oversee, is not guaranteed to perform the testing unless they themselves are qualified.
