A/C Power Systems
This module will cover the General Locations of
the A/C Power Systems through out the vessel.
The A/C Power Systems are divided into three
distinct sub systems:
1. Shore Power (Including Off-Ship Power)
2. Power Generation
3. Power Distribution
Shore Power
Power comes on to
the vessel in the
form of 480 Volt,
Three Phase, 60 Hz
Alternating Current
(A/C) electricity @
100 amps.
The plug on the left
is Shore Power in.
The plug on the
right is Power Out:
480 Volt, Three
Phase, 60 Hz, A/C
@ 50 amps.
Shore Power
The plug is
designed to
disconnect safely
with a live load on
the line. Prevents
arcing.
This feature
enhances the
safety of
connecting and
disconnecting
shore power in the
event we forget to
open the shore
power breaker on
the dock.
Shore Power
Main Switchboard – Shore Power
Shore Power drops down from the main
deck and into the Main Switchboard.
The port side of the Main Switchboard is
the Shorepower section.

Off-Ship Power
Off-Ship 480 Volt, 3 phase, 50 amp service
The fireboat is capable of
providing 480 Volt, Three
phase power to another
vessel, the other fireboat,
or a shore based facility.
Just hook up the off-ship
power cord to the off ship
receptacle and…

Within the Main Switch Board,
behind each generator’s
control and gauging panel, are
the SmartGen
Generator Control HumanMachine Interface (HMI)
displays.
These computers controls the
automated load transfer,
paralleling, and shut-down
features of each generator.
They also measure and record
performance, output and
faults.
Power Generation
Main Switch Board – Generator Breaker
Generator Power Motor Operated Circuit
Breaker
(Allows manual or remote/automatic
connect/disconnect of generator to main
bus)
Each generator has its own motor
operator circuit breaker.
These breakers are located below the
respective generator’s control panel on
the Main Switchboard.
Power Distribution
Main Switchboard
The Main Switchboard is the hub of the electrical distribution system.
Everything ties into the 480 Volt Bus in the Main Switchboard.
Some devices and sub-panels are directly connected to the bus through
breakers.
Other sub-panels are connected to the main bus through step-down
transformers that divide the power to 220 volt systems or 120 volt systems.
Keep in mind, the main bus is divided into a port and starboard side; linked by
the bus tie breaker (normally closed).
Shore power and the Port Generator feed the starboard side of the bus, and
the Starboard Generator feeds the port side of the bus. Also, off-ship power
comes of the port side of the bus.
Yeah, it’s a little backwards, but that’s what we got.
Take a look at the next slide for clarification…

Power Distribution
Step Down Transformers
Power is stepped down form 480 Volt A/C from the
main bus to 220 and 120 Volt A/C via transformers.
There are two (2) transformers for the 220 Volt A/C
system and two for the 120 Volt A/C system. The
system is configured this way for redundancy.
Should the primary transformer for either system
fail, the transformer may be switched to the
secondary at the incoming breaker boxes seen here.
