Don’t let short electrical wires cramp your DIY project. Splice in
extra wire in a few seconds using easy push-in connectors.
Electricians should leave at least six inches of wire in wall boxes,
which will provide enough length to install a new switch or outlet.
When they don’t, it makes stripping wires and getting solid
connections a difficult task.
Wire nuts are effective for connecting wires, but sometimes the wire
is to short to get a proper connection. Using the push-in connectors,
you simply push the bare end of a wire into the connector and a spring
clip will hold it in place. Insert the bare end of your jumper wire
and you’ve got an instant connection.
Watch the video at the link below for a basic demonstration of how to
lengthen your wires.
