LOAD cable:

receptacle in the circuit. This cable should be
connected to the GFCI's LOAD terminals
only. The LOAD terminals are under the
yellow sticker. Do not remove the sticker at
this time.
1. What is a GFCI?
CAUTION
!
A GFCI receptacle is different from conven-
tional receptacles. In the event of a ground
fault, a GFCI will trip and quickly stop the
flow of electricity to prevent serious injury.
Definition of a ground fault:
Instead of following its normal safe path,
electricity passes through a person's body to
reach the ground. For example, a defective
appliance can cause a ground fault.
A GFCI receptacle does not protect against
circuit overloads, short circuits, or shocks.
For example, you can still be shocked if you
touch bare wires while standing on a non-
conducting surface, such as a wood floor.
5. Turn the power OFF
Plug an electrical device, such as a lamp or
radio, into the receptacle on which you are
working. Turn the lamp or radio on. Then,
Wires
go to the service panel. Find the breaker or
fuse that protects that receptacle. Place the
breaker in the OFF position or completely
remove the fuse. The lamp or radio should
turn OFF.
Next, plug in and turn ON the lamp or radio
at the receptacle's other outlet to make sure
the power is OFF at both outlets. If the
power is not OFF, stop work and call an
electrician to complete the installation.

Placement in circuit:
The GFCI's place in the circuit determines if
it protects other receptacles in the circuit.

Placing the GFCI in position A will also
provide protection to "load side"
receptacles B and C. On the other hand,
placing the GFCI in position C will not
provide protection to receptacles A or B.
Remember that receptacles A, B, and C
can be in different rooms.
