GENERATOR
Besides the shore power capability to deliver alternating
current some vessels feature generators for supplying AC
voltage at sea. Generators use their own ventilation and
motor to produce AC electricity on board the vessel.
The following illustration is part of the main DC panel
discussed earlier in this chapter.

Generator Ventilation
Some vessels feature generators as optional equipment.
Before the generator is started both blower switches are to
be activated. The blowers evacuate any fumes from the bilge
area. Read and understand the blower label on the generator
portion of the DC control panel.

Before Activating Generator
Before starting the generator make sure all equipment
switches and shore power breakers are in the “off ” position.
This procedure helps prevent any voltage surges when the
generator starts. Refer to the AC panel illustration earlier.
Generator On Switch
After the blowers are activated and run for at least 4 minutes
the generator can be started. Energize the toggle style on
switch until the generator starts. At that point release the
switch and the generator starter will disengage from the
flywheel. The generator should continue to run on its own.
Generator Main Breaker
After the generator starts the current produced needs to
correctly routed to its final destination. Make sure the shore
1 switch is in the off position and slide the generator arm
to the uppermost point. While holding it there, turn on
the generator breaker. This will begin the AC current
routing. The second portion of the process is accomplished
with the transfer slider.
Generator Transfer
With the generator breaker in the on position energize the
transfer breaker. At this point move the transfer slider
down. Now you can complete the AC power routing by
activating the shore 2 breaker. The appropriate equipment
breakers can now be turned on. Monitor the AC load
current display for total amperage draw as equipment is
activated.
Generator Shutdown Procedure
To shut the generator down deactivate all AC equipment
breakers. Move the transfer slider upward and deactivate
the transfer breaker. Move the generator slider upward and
deactivate the generator breaker. Finally, hold the generator
stop toggle switch until the generator completely stops.
Deactivate the blower breaker(s) at this time.
TO PREVENT POSSIBLE GENERATOR
DAMAGE ALL SHORE POWER
BREAKERS AND AC SWITCHES ARE TO BE
DEACTIVATED BEFORE STARTING OR
STOPPING GENERATOR.
