The shipboard switchgear is responsible for the power distribution of the entire vessel, ensuring the normal operation of equipment and systems. The switchgear is crucial on board and must not be operated by unauthorized personnel to ensure proper equipment operation.
Therefore, unauthorized personnel are strictly prohibited from touching or operating any switches on the switchgear.
Shutting down the generator requires no-load operation. When switching to shore power, the wiring phase sequence must be checked, and operation under load is prohibited. Before shutting down, always disconnect the generator load to ensure a no-load shutdown. Direct shutdown under load is strictly prohibited to protect the generator from damage.
When performing shore power switching operations, all power switches on the shore power panel must be turned off first. Then, carefully check the accuracy of the wiring and phase sequence. Only after confirming that everything is correct can the ship-to-shore power switchover be performed. Operation under load is strictly prohibited to ensure safety.
