Legrand 1595H Series GFCI Receptacle - Manual

• To prevent severe shock or electro-
cution, always turn the power OFF
at the service panel before working
with wiring.
• Use this GFCI receptacle with
copper or copper-clad wire. Do not
use it with aluminum wire.
• Do not install this GFCI receptacle
on a circuit that powers life support
equipment because if the GFCI
trips, it will shut down the
equipment.
• For installation in wet locations,
protect the GFCI receptacle with a
weatherproof cover that will keep
both the receptacle and any
plugs dry.
• Must be installed in accordance
with national and local electrical
codes.
Please read this leaflet
completely before
getting started.
3. Should you install it?
Installing a GFCI receptacle can be
more complicated than installing a
conventional receptacle.
Make sure that you:
• Understand basic wiring principles
and techniques.
• Can interpret wiring diagrams.
• Have circuit wiring experience.
• Are prepared to take a few minutes
to test your work, making sure that
you have wired the GFCI receptacle
correctly.
4. LINE vs. LOAD
A cable consists of 2 or 3 wires.
LINE cable:
Delivers power from the service panel
(breaker panel or fuse box) to the
GFCI. If there is only one cable enter-
ing the electrical box, it is the LINE
cable. This cable should be connected
to the GFCI’s LINE terminals only.
LOAD cable:
Delivers power from the GFCI to
another receptacle/outlet 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.
6. Identify cables/wires
IMPORTANT:
Do not install the GFCI receptacle in an
electrical box containing (a) more than
4 wires (not including the ground wires)
or (b) cables with more than two wires
(not including the ground wire). Contact
a qualified electrician if either (a) or
(b) is true.
• If you are replacing an old recepta-
cle, pull it out of the electrical box
without disconnecting the wires.
• If you see one cable (2-3 wires), it is
the LINE cable. The receptacle is
probably in position C (see diagram
to the right). Remove the receptacle
and go to step 7A.
• If you see two cables (4-6 wires), the
receptacle is probably in position A or
B (see diagram to the right). Follow
steps a-e of the procedure to
the right.

Procedure: box with two cables
(4-6 wires)
(a) Detach one cable’s white and hot
wires from the receptacle and cap
each one separately with a wire
connector. Make sure that they are
from the same cable.
(b) Reinstall the receptacle in the
electrical box, attach the wall plate,
then turn the power ON at the
service panel.
(c) Determine if power is flowing to the
receptacle. If so, the capped wires
are the LOAD wires. If not, the
capped wires are the LINE wires.
(d) Turn the power OFF at the service
panel, label the LINE and LOAD
wires, then remove the receptacle.
(e) Go to step 7B.
Placement in circuit:
The GFCI’s place in the circuit
determines if it protects other
receptacles/outlets in the circuit.
Sample circuit:
Placing the GFCI in position A will
also provide protection to “load side”
receptacles/outlets B and C. On the
other hand, placing the GFCI in posi-
tion C will not provide protection to
receptacles/outlets A or B. Remember
that receptacles/outlets A, B, and C can
be in different rooms.
1. What is a GFCI?
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 per-
son’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 com-
pletely 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 com-
plete the installation.
