How to start an Emergency generator

How to start Emergency Generator on ship?

There are three ways to start an emergency generator:

  1. Automatically starts: When it senses that the power supply is gone, main generators are not running black out is there so it will start automatically and take load.
  2. Manual start: Doing it manually by going into the emergency generator room there is a switch inside the panel- on one side it is written engine, if we put it on engine then the generator will only start. Another is engine Air Circuit Breaker (ACB) that means it will start and it will connect the ACB to come on load as well. It gives supply to the electric motor, this electric motor starts cranking the emergency generator and it starts.
