Line vs. Load
A cable consists of 2 or 3 wires
INSTALLATION GUIDE
L
INE Cable
Delivers power from the service panel (breaker
panel or fuse box) to the GFCI. If there is only
one cable entering the electric 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
receptacles 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.
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.
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
below). Remove the receptacle and go to step
"Connecting the Wires A
"
)
•
If you see two cables (4-6 wires), the receptacle is
probably in position A or B (see the diagram below)
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, and
label the LINE and LOAD wires.
Then, remove the receptacle
e)
Go to step "Connecting the wires B"
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 different rooms.
Connecting the Wires (choose A or B):
A — One Cable (2-3 wires) Entering the Box
Connect the LINE cable wires to the LINE terminals:
•
The WHITE wire connects to the WHITE terminal (Silver)
•
The BLACK wire connects to the HOT terminal (Brass)
Connect the grounding wire (only if there is a grounding wire):
•
For a box with no grounding terminal, connect the LINE cable's bare copper (or
GREEN) wire directly to the grounding terminal on the GFCI receptacle
•
For a box with a grounding terminal, connect a 6" bare copper (or GREEN) 12 or
14AWG wire to the grounding terminal on the GFCI. Also, connect a similar wire
to the grounding terminal on the box. Connect the ends of these wires to the
LINE cable's bare copper (or GREEN) wire using a wire connector. If these wires
are already in place, check the connections.

Complete the installation:
•
Fold the wires into the box, keeping the
grounding wire away from the WHITE and HOT
terminals. Screw the receptacle to the box and
attach the faceplate
Go to the next step "Test Your
Work" (explained on the
last
page of this
instruction manual)
