What is an electrical pigtail?

An electrical pigtail is a technique used to lengthen short wires or combine multiple wires together and leave one conductor that can connect to electrical devices such as a switch or outlet, and it's simple enough for homeowners to perform on their own.

Knowing how to make an electrical pigtail is a must for anyone into DIY projects. When wires are too short to comfortably and safely work with, this technique can save you a lot of time and headache. This DIY guide explains how to make an electrical pigtail so you can complete simple at-home electrical projects. Read the step-by-step list below or check out our detailed video.

Tools Needed for Electrical Pigtails


  • Screwdriver
  • Wire Cutters
  • Wire Nuts
  • Wire Strippers
  • Voltage Tester
  • Extra Wire

1. Cut Power

First and foremost, cut the power - safety first! You should never begin any electrical work without shutting off all power sources. Go to your breaker box and shut off the breaker powering the electrical wires you'll be working with. Then, if you don't already have your old outlet or switch removed, go ahead and unscrew it from the wall. After you've cut the power, removed the outlet, and exposed the wires, double check that the electrical current is off with your voltage tester. If there is still power flowing to the wires, your tester will light up and/or make noise.

2. Disconnect from Device

Once you've confirmed the wires are dead, disconnect them from the device and separate your wires by color. There should be copper grounding wires, white neutral wires, and black (or red) hot wires.

3. Prepare Wires

When you have your wires grouped by color, it's time to prepare them for the pigtail. Clip the end of the wires to the same length, then strip them so that they have the same amount of exposed copper, you only need about a half an inch - this will make it easier to twist them together. Now take your extra, longer wires that you will be making the pigtails with and strip the ends of those wires as well. After you've prepared your wires and they are looking nice and even, it's time to add the pigtail!

4. Twist Wires Together

Place your extra neutral wire next to the neutral wires inside the box and use your pliers to twist the wires together. (Pro Tip from a Utah residential electrician: twist the wires clockwise! When you add the wire nut, you'll also be twisting it in a clockwise motion, so twisting the wires clockwise beforehand ensures a tight electrical connection). After you've twisted the wires together, clip off the end to make sure everything will be covered by the wire nut. Now you can screw on your wire nut. Repeat this step for the remaining two groups of wires.

5. Install New Switch/Outlet

Now that you've got wires that are neat and plenty long to work with, you can get ready to install your new switch or outlet. But first, push the bundles of wires into the back of the electrical box leaving only the longer pigtail poking out from the wall. You want to cut down your new pigtail wires to about 6-7 inches so you don't have an excessive amount of wire filling the box.

6. Finish Up

Go ahead and strip the end of your new pigtail wires to make fresh connections. Attach the wires to your outlet or switch and then push the wires back into the box. Screw the device into the box and install the cover plate. Turn the power back on and test your work. That was easy!

Doug's Story

"I'm retired Army. The house was built in 1950 and a lot of improvements have needed to be done. I have never met a group of finer young people that were super qualified in every area -- whether it was heating, plumbing, electrical or whatever -- they would be the type of team that I would want to put together myself if I were running a company, and I have nothing but praise. I know I can trust their work."

We had Chris come over and do some electrical work on our house. He was right on time and did a great job. Chris is a great clean cut guy and didn’t mind our 2 year old following him around and asking what he was doing the whole time. He made the repair quickly and professionally. I would call again.
