Upon failure of the ships normal electrical power supply, by means of what device does the emergency generator supply power to the emergency switchboard, but not the main switchboard?

🔍 Key Concepts

• Emergency generator function and location in the ship's power system • How the emergency switchboard is isolated from the main switchboard when normal power fails • Purpose of devices that automatically shift loads when normal power is lost

💭 Think About

• Think about which device is specifically used to connect one power source to a bus automatically when another source fails. • Ask yourself: which choice names something that actually switches between power sources, rather than just carrying power or giving an alarm? • Consider how the emergency system avoids backfeeding power into the main switchboard when only emergency power should be energized.

✅ Before You Answer

• Which option is a switching device (not just a bus, transformer, or alarm circuit)? • Which option would logically be placed between the emergency generator and the emergency switchboard to control connection? • Eliminate any option that does not clearly have a role in automatic transfer of power after normal supply failure.
