Ground Fault Circuit Interrupter
(GFCI)
Various outlets in the motorhome, particularly
those near sinks and water supplies, are
connected to a GFCI. A GFCI detects electrical
current that is travelling along and unintended
path and stops the current to reduce the risk
of electrical shock and re. If a GFCI breaker
trips, unplug all the appliances on that circuit,
and press the reset button (3) on the outlet. To
test the operation of the GFCI breaker, press
the test button (4).
NOTE: GFCI recepticals may not appear as
shown.
If the GFCI trips repeatedly, have the problem
investigated and repaired by a qualied
technician before using it again.
For detailed wiring, GFCI locations and GFCI-
Protected receptacles see the AC wiring
schematics.

The GFCI will not completely eliminate the
risk of electrical shock. Small children or
persons with heart conditions should be
extra cautious because electrical shock
could cause burns or cause the heart to
stop even when a GFCI is present.
NOTE: The GFCI circuit
in the bathroom will trip
when a fault occurs at
the exterior receptacle.
The galley receptacle
is protected through
a GFCI located in the
bedroom or couch area.
