What main function do the switchboards serve in relation to shore power?

The main function of switchboards in relation to shore power is to provide power transfer management. Switchboards are critical components in electrical systems, especially in marine and industrial applications, where they facilitate the connection and management of different power sources. When a vessel is docked, switchboards allow for the seamless transfer from onboard power generation to shore power, ensuring that the electrical systems aboard can be powered by the external grid when available. This capability is essential for reducing fuel consumption and emissions while at port.

Additionally, switchboards are equipped with protective devices that help manage and distribute the electrical load efficiently and safely. By ensuring that power transfer is managed properly, switchboards play a crucial role in maintaining the stability and reliability of power supply, enabling boats to switch between different power sources without interruption to operations.
