Adding a New Outlet from One that Already Exists

If you have an existing outlet, there are a few methods you to use to add a new outlet to it. This is generally done when you desire to install an extra outlet at a new place, but need to tap into an existing power source.

There are a few things you will need to have to successfully add a new outlet:

  1. hot conductor (unswitched/ungrounded conductor wire)
  2. a neutral, grounded leg wire
  3. an equipment grounding wire

If your setup is modern, then it should already have what you need to add another outlet, though you may not have an unswitched hot wire available for three and four way switch systems.

It is important to check whether or not your switch location has all the necessary wires you will need to tap into available before beginning your project. Generally, most outlet receptacles will have everything you need, but it is always best to be certain.

Since most outlets have the needed wiring available, they tend to make a great choice for a supply to run power to a new wire and add another outlet.

When you are looking at the wiring, the neutral wire (grounded leg), attached with a silver screw, will connect to a gray or white wire. The hot wire will be attached with a brass colored screw. The grounding wire is the one kept in place with the green screw. The grounding wires are typically either green or bare.

Once everything mentioned above is covered, you will be ready to add the new outlet. That is done by stripping wires and piggy tailing them together. A simple search online will bring up a lot of information on how to connect the wires to make the new outlet hot.
