Where are circuit breakers typically located on an aircraft?

• A. Located mainly in the flight deck but also in the galleys
• B. In every passenger seat
• C. In lavatories only
• D. In cargo hold only

Answer: (A)

Circuit breakers are safety devices that automatically interrupt electrical circuits when a fault is detected, so they can be reset or managed by the crew if a fault occurs. On aircraft, quick access is crucial, which is why they’re placed where the pilots can reach them easily: mainly in the flight deck where the primary electrical panels and fault indicators are located. Some breakers are also provided in cabin service areas, such as the galley, to control or isolate equipment used in the cabin. They aren’t placed at passenger seats, in lavatories only, or exclusively in the cargo hold, because those locations aren’t practical or safe for handling electrical faults. So the typical arrangement is mainly in the flight deck with some in the galleys.
