Extending Too Short Electrical Wires by Connecting Jumpers
Don’t let short electrical wires get in the way of your project. Connect excess wire in seconds using simple plug-in connectors .
Electricians should leave at least six inches of wire in wall boxes to provide sufficient length to install a new switch or outlet. When they don’t, stripping wires and getting reliable connections becomes a challenge.
Wire nuts are effective for connecting wires, but sometimes the wire is too short to make a proper connection. With push-in connectors, you simply insert the bare end of the wire into the connector and a spring clip holds it in place. Slide in the bare end of the jumper and you have an instant connection.
