Who is authorized to disconnect power plant output cables?

Who is authorized to disconnect power plant output cables?

• A. Operations personnel
• B. Electrical Systems personnel
• C. Maintenance personnel
• D. Security

Answer: (B)

Disconnection of power plant output cables is an electrical isolation task that must be done by personnel trained and authorized to work on electrical systems. Electrical Systems personnel have the training to de-energize, lock out, and tag out the equipment, verify that no voltage is present, and use the proper PPE and tools. They coordinate the sequence so the plant can be safely isolated without the risk of energizing the cables during maintenance or testing and ensure the switchgear and cables are secured before anyone works on them. Operations personnel control the plant’s operating state and may initiate stop conditions, but they aren’t the ones designated to perform the actual disconnection of high-energy cables. Maintenance personnel work on equipment after it has been isolated and released by the electrical team, not the initial disconnection. Security handles access and protection but not the electrical isolation procedures.
