Gfci; Testing Instructions - Jayco COVE 2002 Owner's Manual

that the polarity of the external power is not reversed, in order to avoid harm to appliances and
personal electrical shock. Polarity indicators may be purchased in most electrical and hardware
stores.
It is strongly recommended to avoid the use of extension cords. If an extension cord is used, it
MUST be the same amperage rating as the park trailer power cord. Using an improper extension
cord will cause overheating of the cord and equipment as well as possibly causing premature failure
of the AC equipment.
I
WARNING: Do not use an adapter, cheater or extension cord that will break the
continuity of the grounding circuit connected to the third pin. NEVER remove the
grounding pin to connect a non-grounded, two-prong receptacle. Any deviation from
this will potentially cause a fire from overheating.

GFCI

Each park trailer has a GFCI receptacle (Fig. 4-25) installed. These
initials mean "Ground Fault Current Interrupter." This special receptacle
has been designed to reduce the possible injury caused by electrical shock.
An example of ground fault current is the current which would flow
through a person who is using or touching an appliance with faulty
insulation and, at the same time, is in contact with an electrical ground
such as a plumbing fixture, wet floor, or earth.
This GFCI receptacle will not protect against short circuits or overloads.
The circuit breaker or fuse in the electrical panel which supplies power to
the circuit provides this protection.
When this GFCI receptacle is tripped, it has interrupted ground fault current caused by such things
as faulty insulation or wet wiring inside some appliance or equipment connected to the circuit. The
faulty equipment should be repaired before is it used again.
This special receptacle should be tested monthly while the park trailer is being used.

TESTING INSTRUCTIONS

1. Plug a lamp or radio into the receptacle on the face of the GFCI.
2. Push and release the RESET button.
3. The lamp should light at this time.
4. Press the TEST button.
5. RESET button should pop out indicating "Trip" and the lamp should go out. (If the GFCI is
manufactured with an indicator light, the light should glow when the device has tripped.)
6. If the GFCI did not trip, do not use. Call a qualified electrician to service or replace the
receptacle. The ground fault protection is no longer working and the GFCI may not be
working properly.
7. To restore power after tripping, press in the RESET button. It must remain in. (If an indicator
light is furnished, it will be off.)
