Legrand 1595H Series GFCI Receptacle Rev.B User Manual

Installing and testing a gfci receptacle, Line vs. load, Should you install it

background image

• To prevent severe shock or

electrocution, 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.

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.

6. Identify cables/wires

IMPORTANT:

Do not install the GFCI receptacle

in an electrical box containing (a)

more than 4 wires (not including the

grounding wires) or (b) cables with

more than two wires (not including the

grounding wire). Contact a qualified

electrician if either (a) or (b) is true.
• If you are replacing an old

receptacle, 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) Re-install the receptacle in the

electrical box, attach the faceplate,

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 in the circuit.
Sample 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.

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

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.

Self-Test GFCI Receptacle with

SafeLock Protection
This is a Self-Test GFCI Receptacle

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.

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.

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 entering 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 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.
