______ are hook-stick operated and gang-operated.

______ are hook-stick operated and gang-operated.

• A. Disconnects
• B. Breakers
• C. Switches
• D. Relays

Answer: (A)

Disconnects are hook-stick operated and gang-operated. A hook-stick is a long insulated bar that lets the operator move the switch contacts from a safe distance, which is essential when dealing with high voltages. Gang-operated means several disconnect switches are mechanically linked to operate together with a single motion, allowing rapid, simultaneous isolation of a section of the system such as a feeder or bus. This combination is characteristic of isolation devices used to safely disconnect parts of the circuit for maintenance or clearance. Breaker devices are protective and are typically controlled by relays and control circuitry, not operated by a hand-held hook-stick. Switches is a broader term, but the specific hook-stick and gang linkage describe disconnect switches used for isolation. Relays are protective control elements, not manual isolation devices.
