A push wire connector makes it easy to extend the length of a short wire.
Most companies make the electrical connector work for a wide range of wire sizes. The types I have used will accommodate wires from 12 to 22 gauge. You can also purchase push wire connectors that have from 2 to 8 ports.
Check your local codes, but in our area they are popular to extend short wires in a box or to create a pig tail wire.

How to Create a Pigtail Electrical Connection

If you have an outlet that needs two or more wires going to one screw terminal, you should always create a pigtail to make the connection.

A pigtail connection is a safe way to make sure multiple wires stay connected to a screw terminal. You can also create a pigtail to extend a wire that is too short in an electrical box.

You will need to know the wire size of the circuit you are working on. You need to match the pigtail to the size of the circuit. In most homes, you will be working on a 15 amp circuit, using 14 gauge wire. In some situations, like a kitchen, you may have a 20 amp circuit, using 12 gauge wire.
Always turn off the electric to any circuit you are working on.
