11. SHORE connection controller
11.1 SHORE connection controller overview
11.1.1 Description
A SHORE connection controller controls and protects the system and the shore connection breaker when a shore connection is
connected. When the shore connection is in use, it is normally the ship's only power source. However, the gensets may run in
parallel with the shore connection for a limited time.
11.1.2 Applications
There is no restriction on the number of SHORE connection controllers.
