Do not switch the Air Conditioning unit salon breaker
ON until after the seacock supplying the air conditioning
system with seawater has been opened. Refer to Air
Conditioning System for more information.
NOTICE
OPERATING AC EQUIPMENT
Never reset a breaker that has automatically
tripped without first correcting the problem.
Failure to correct the problem may create a
dangerous situation.
WARNING
!
Power to the AC components is controlled by circuit
breakers and individual controls for each component.
Electricity to the AC components can be controlled by
switching the breakers from the AC control center ON or
OFF. The breakers also protect the electrical system by
automatically disconnecting the circuit from the power
source in the event of a short or overload.
GROUND FAULT CIRCUIT
INTERRUPTERS
Figure 7-20
Each AC receptacle is protected by a Ground Fault
Circuit Interrupter (GFCI). The GFCI measures both the
amount of current flowing to the circuit’s receptacles and
the amount of current returning from the receptacles.
The GFCI compares the two values once measured. If
the values are not the same, the GFCI instantly trips, and
power is shut off to the receptacles.
An electrical shock received through a standard
receptacle will continue through a person’s body and flow
into any grounded object that the person is touching or
standing on. The GFCI, however, will immediately shut
off power to the receptacle. Shutting off the power limits
the time the person is being shocked to a brief moment,
significantly reducing injury to the person.
GFCI Receptacle Locations
The receptacles protect a group of receptacles that can
include both open outlets and outlets already in use for
built-in equipment. All outlets onboard are connected to
a GFCI.
Testing GFCI Receptacles
GFCIs have TEST and RESET buttons located on the
receptacles.
Switch the TEST button ON/OFF switch to ON to reset a
GFCI that has tripped.
Press the RESET button to reset the GFCI after it has
tripped. Resetting a GFCI allows electricity to flow again
to the receptacle.
Test each GFCI circuit once per week.
GFCI Receptacle Locations:
• Receptacle Circuit 1-Port Aft Salon
• Receptacle Circuite 2-Galley
