• 
  In what event is the emergency generator started?
  
• 
  The emergency generator is started in the event of a power failure or loss of main power.
  
• 
  Does the emergency generator have its own switchboard?
  
• 
  Yes, the emergency generator has its own switchboard.
  
• 
  On what types of ships must emergency generators be able to supply power longer: on tankers or passenger ships?
  
• 
  Emergency generators must be able to supply power for 18 hours on oceangoing cargo ships and tankers, and for 36 hours on passenger ships.
  
• 
  What is it necessary to do to get the ship’s service generators back on line?
  
• 
  To get the ship's service generators back on line, several auxiliary motors fed from the ship's service switchboard need to be started, and the bus transfer circuit breaker interlock can be manually bypassed. However, care must be taken to ensure the ship’s service generator circuit breakers are open since the emergency generator is usually not designed to be run in parallel with the ship’s service generators.
