LEGRAND GFCI Installing And Testing

• To prevent severe shock or
electrocution, always turn the
power OFF at the service panel
before working with wiring.

1. What is a GFCI?
CAUTION
!
A GFCI receptacle is different from
conventional 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, 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.
2. The GFCI's features
Self-Test GFCI Receptacle with
SafeLock Protection
This is a Self-Test GFCI Receptacle
FRONT VIEW
with SafeLock™ Protection; it
conducts an automatic test every three
seconds, ensuring it's always ready
to protect. If the device fails the test,
the indicator light flashes to signal
that the GFCI should be replaced.
It also has our proven SafeLock
Protection feature: if critical
components are damaged and
protection is lost, power to this
receptacle, and any downstream
receptacles, will be disconnected.
