Ground Fault Circuit Interrupter (GFCI)
The GFCI breaker provides reliable overload and
short-circuit protection� GFCI breakers protect
against ground faults and provide additional safety
to the occupants of the touring coach on all outlets/
receptacles� A ground fault occurs when current travels
along an unintended path to ground, possibly through
water or a person, which may result in an electric
shock� The GFCI compares the amount of current
going to and returning from the device plugged into the
circuit's outlet/receptacle� When the amount of current
going to the device differs from the amount returning,
the GFCI interrupts the current within a fraction of
a second, removing power from the circuit, and
protecting the user�
Each GFCI circuit breaker is calibrated to trip with a
ground current of 5 mA or more� Since most people
can feel as little as 2 mA, a shock may be felt� The
shock should be of such a short duration that the
effects would be reduced, less than what would
normally be a dangerous level� However, persons with
acute heart problems or other conditions that can make
a person particularly susceptible to electric shock may
still be seriously injured�
While the GFCI circuit breaker affords a high degree
of protection, there is no substitute for knowing that
electricity can be dangerous when carelessly handled
or used without reasonable caution�
The system incorporates GFCI breakers that
implement an auto-self-test functionality� When turned
off, these breakers require external AC power to be
present before they can be turned back on� If power is
present, and the breaker refuses to stay on, consult an
electrician or certified RV technician.
WARNING
The GFCI circuit breaker will NOT reduce shock
hazard if contact is made between a HOT load
wire and a neutral wire or two HOT load wires.
GFCI circuit breakers provide protection only to
the circuit to which it is connected.

GFCI Breaker Test
Perform this test on the GFCI circuit breaker each
month and record the date�
A
B
1� With handle A in the "ON" position, press PUSH TO
TEST button B�
2� Handle A should move to the TRIP position,
indicating that the GFCI breaker circuit is open�
3� Move handle A to the "OFF" position and back to
the "ON "position to restore power�
If the device remains on when the Test button is
pushed, the GFCI is not working properly or has
been incorrectly installed (wired improperly)� If your
GFCI is not working properly, call a qualified, certified
electrician who can assess the situation, rewire the
GFCI if necessary, or replace the unit�
Power Center Fuses
When blown, the fuses housed in the power center will
be illuminated by a blown-fuse LED indicator to help
determine which fuse needs replacing� The indicator
will only illuminate if the affected circuit remains closed
and/or has a load� For example, suppose a light is
burned-out or the switch to the light is off, resulting in
an open circuit� In this case, the fuse will not illuminate�
NOTICE
Most fuses will require a qualified technician
to access and replace. Contact your dealer or
Airstream Service Center.
Auxiliary Fuse Locations
In addition to the 12-volt fuses and breakers located in
the power center, several components of the coach are
protected by in-line fuses� These are usually located at
or near the components they protect� There are also
several fuses located under the driver and passenger
seats� For additional information,
