Which of the following is NOT a requirement of the circuit disconnecting means?

• A. Red marking
• B. Accessible only to qualified personnel
• C. Protected by a ground-fault or arc-fault circuit interrupter
• D. Identified as FIRE ALARM CIRCUIT

Answer: (C)

The thing being tested is how the disconnecting means is identified and accessed so you can safely and quickly shut off power when needed. It should be easy to locate and operate by someone who’s trained, and it should stand out clearly, often with red marking so technicians can spot it immediately in an emergency. It is expected to be readily accessible to qualified personnel, meaning trained people can reach and operate it without barriers, not that only those people can ever access it. For circuits like a fire alarm, labeling the disconnect as a FIRE ALARM CIRCUIT helps ensure life-safety systems aren’t accidentally disconnected. However, having the disconnecting means protected by a ground-fault or arc-fault circuit interrupter is not a requirement of the disconnecting means itself; GFCI/AFCI protection is a circuit protection requirement, not a characteristic of the disconnecting device.
