Step 5. Now you can start to
connect the GPCI. To begin, count the number of wires you just
disconnected from the old receptacle. You’ll either have three wires
each of white, black, and bare wires—or you’ll have five—a pair of white
and black wires and a single bare wire. If you’ve got five wires, skip
to steps 6A and B. If you’ve got three wires, clip off the stripped ends
of the wires and use your combination tool to strip away about 3/4” of
insulation. Then use your needlenose pliers to bend the stripped
portions in small, clockwise hooks and go to step 7.
Step 6A. If you’ve got five
wires, clip off the stripped ends of the wires and use your combination
tool to strip away about ¾” of insulation. Now cut three 3” pieces of
14-gauge wire—one bare. one white, and one black. Strip about ¾” of wire
from both ends and then use your needlenose pliers to make a clockwise
hook at one end of each. These are your pigtails.
Step 6B. Hold the straight
end of the white pigtail next to the ends of the two white wires coming
from the electrical box. Slide a wire connector over the ends and twist
it clockwise until the connector is snug. No bare wire should be
visible. Repeat this procedure for the black wires and black pigtail,
and then for the two bare wires and the bare pigtail.
