How to Pigtail Electrical Wires

How to Pigtail Electrical Wires: A Guide by James Adams of ABR Electric
abrelectric.com/prosper
Pigtailing is a technique used in electrical wiring to extend or manage connections when adding devices or when there are not enough spaces in a junction box. This guide, based on the expertise of James Adams, will walk you through the process of pigtailing electrical wires.
Materials Needed
Wire strippers
Wire nuts
Electrical tape
Screwdrivers
Voltage meter
Safety Precautions
Ensure power is off before starting. Use a voltage meter to confirm there is no power.
Be cautious when stripping wires to avoid nicks.
Steps for Pigtailing
1. Preparing the Wires
Identify Wires: Locate the wires you need to work with (grounds, neutrals, and hots).
Cut Wires to Length: Ensure all wires are of the same length for consistency. Leave the ground wire slightly longer.
Strip Wires: Carefully strip the insulation from the wires, ensuring not to nick the copper.
2. Creating the Pigtail
Ground Pigtail:
Twist the ground wires together.
Add a short piece of wire (the pigtail) to the bundle.
Secure with a wire nut.
Neutral Pigtail:
Align the insulation points of the neutral wires.
Twist the wires together and add the neutral pigtail.
Secure with a wire nut. If the twist isn’t neat, redo it for a solid connection.
Hot Pigtail:
Follow the same process as the neutral pigtail for the hot wires.
3. Ensuring Solid Connections
Twist the wire nut until the wires and the bundle start to twist with it. This indicates a tight and secure connection.
Do not reuse old wire nuts.
4. Wiring the Device (e.g., Plug)
Use the wire strippers to create hooks on the wires.
Attach the wires to the plug, ensuring they are wrapped clockwise around the screws.
Tighten all screws, including the ones not used, to prevent shorts.
5. Finalizing the Installation
Pre-bend the wires to fit them back into the box neatly.
Ensure the ground wire does not ride back up and cause a short.
If working with a switch box, ensure all neutrals are pigtailed.
Benefits of Pigtailing
Prevents loose connections and voltage drops.
Ensures continuous power through the circuit even if the device fails.
Useful in both old and new constructions for reliable power distribution.
Conclusion
Pigtailing is a valuable skill for managing electrical connections and ensuring safety and reliability in your electrical system. Remember to prioritize safety and double-check your connections for a successful installation.

I've pulled in a dual set of 20 Amp wire. One will be dedicated to the refrigerator and one will power four 20 Amp plugs (2 GFCI, 2 regular). I have a lot of extra 12 gauge wire (the three wires are sheathed in a yellow outer plastic wrap). What's the approach to accomplishing this? Thanks much if you can respond.

    The only thing I saw that you were doing (kind of wrong) was when you were twisting your wires together, you were twisting the first two wires tight then adding the third wire and twisting it tight, then when you added the fourth wire it was riding up and not blending in with the other wires'. When I twist multiple wires together, I will barely twist the first two together, maybe one full twist, then add the third, again only twisting it one full twist the add the fourth. Then when all the wires are bundled, I will twist them tight and put on the wire nut. Other than that, you do things the same way I do.

    Among construction workers there's a brotherhood of people that have a soul it's good to hear from one of you one of us. I'm hoping you can answer this simple question can I run all of my outlets with 10 gauge and then just pigtail a little chunk of 12 gauge on the end? I know the wire is more expensive but I'm going to buy it off Facebook and probably get it for the same price that they wanted for the new 12 and I like that heavier gauge .

    I am a DIY’r and will connect two receptacles differently. This is a trick I learned from seeing how an electrician wired a double receptacle box at my house. Make the hot, neutral & ground wires about 12” long coming out of the box. Strip the insulation off the ends of the hot and neutral wires. Then strip about 1/2” of the insulation half way down the hot and neutral wires. The ground wire probably does not have insulation and should not need wire stripping. Wrap the hot, neutral and ground wires around the appropriate screws of the first receptacle at the halfway point where the insulation was removed. Next wrap the striped ends of all three wires around the appropriate screws on the second receptacle. I like this method better than the pigtail method because it does not require wire nuts for the connection of the two receptacles and will keep the download circuit live if there are additional receptacles. If there are additional receptacles downstream, I have kept the run of Romax continuous with 12” coming out of the box. Strip 1/2” of insulation at two appropriate spots on the hot and neutral wires and then wire up the two receptacles the same as stated previously. This wiring method uses absolutely no wire nuts in the box.

    Are pigtails required by code? No. Are they used for good workmanship? Yes. The real advantage for the pigtails, other than disabling the circuit if the receptacle or connection to the receptacle malfunctions, is you can make the pigtails the proper length to fold neatly into the box. The pigtail connection are organized in the box as far to the rear neatly as possible. This gives plenty of space to fold the pigtail wires and fit the receptacle properly in the box as shown in the video. To make installation even easier with the triple Romex into a single duplex receptacle box (which is more than usual unless the receptacle is split), IDEAL actually made a 12 AWG THHN stranded wire dedicated pigtail with a wire nut on one side and a captive spade connector at the other. The flexible stranded wire puts almost no side load force on the screw connections, and the spade fits flat in relation to the base connection and the screw head. Unfortunately they no longer make the Black and White versions of this pigtail, probably due to cost. However, even though they were only used on rare occasions, when needed they worked very well.

    For a duplex receptacle there are screw connections for each single receptacle to support splitting the duplex receptacle into two separately controlled single plug outlets. If you do not split the receptacle, which is obviously very common, then it is tempting to use the "extra" screw connections to make the daisy chain at the receptacle rather than making a spliced pigtail. In the case of a simple SPST wall mounted switch there are only two screw connections for the circuit, and one screw for the ground. I don't know how you would daisy chain at the switch unless you double up on the screw connections, with common rated switches doubling up is a code violation. Is this what you mean? @@cryengine_x

    @@windward2818 i think so, i really dont know about electrical stuff. But there are 3 "line/load" wires going into the (I believe single pole?) switch. Two on the two screws and one in one of the backstabs. So in googling about this apparently they are feeding another switch off this one. Probably there is a switch (actually 3 with one plate) directly across from it on the other side of the wall, I'm guessing thats it. Does that make any sense? I discovered this because I'm trying to put in a smart switch, and although my home is only 23 years old, the switch wiring is as i described not two line/load like their diagram. From what I googled I can make a pigtail off two of the black wires and be ok. they also did not connect the ground wire to the green screw on the switch at all. which evidently in a plastic box is not particularly dangerous, but is still code to do so.

    So, you have discovered a code violation. Only one wire or termination allowed per screw. You can daisy chain on a non-split receptacle without violating this rule because you have more screw terminations than a wall switch. However, even though you have not violated code, you have not achieved good workmanship, which in the case of the receptacle requires the use of a pigtail. With a wall switch you have no option, you must use a pigtail splice. If you do light industrial AC distribution wiring you will be using a lot of stranded wire in conduit for 20 Amp receptacle branch circuits. So, we also have a workmanship question to ask, that is, can I use a stranded wire underneath a screw. With a solid wire the answer is yes. With a stranded wire the answer is yes, but I don't really see this as a method from the master electricians. The solution is to use stranded wire terminated receptacles that don't have screws, so you can use a standard wire splicing method (like a wire nut or a lever splice (which I don't like)). Some master electricians if faced with using screw terminating receptacles (not the preferred type of device) will use a captive spade terminal (having small nubs and bent up ends so they will not come off if the screw is loose) crimped onto the wire (using a certified crimping tool designed for that particular spade terminal) and then placed under the screw and the screw torqued to specification. I have tried all three methods of screw termination for stranded wire and the one I like is the captive spade terminal and with screw torqued to specification. It just feels correct. Some of my installations are more than 30 years old now using spade terminals and I have never heard of a problem with a loose connection.@@cryengine_x

    I don’t understand how people can think that pigtailing makes troubleshooting easier. Pigtailing introduces another failure point, puts more wire in the box and the fact of the matter is the bus bar on the side of an outlet is not the failure point of the outlet. Sure the screws can loosen. But a wire nut can fall off or be poorly installed too. Poor workmanship can be with how you install wire nuts just as easily as how well you loop a wire around a screw and tighten it. If anything the screws are probably easier for DIYers. There are situations where pigtails are necessary but unless you have to just use the bus bar on the side of the device.

    Anybody notice how bad the new boxes are? Such cheap garbage that break or bend while trying to push cable into the box, especially multiple 12/2.

    Yes, I have to pre-punch with needle nose pliers.

    Yes, I had metal boxes installed in my house. 4x4 metal box with a mud ring.

    If you are a teacher you are really bad. putting all the wires together and twisting them all at once makes a better connection. Stabbing wires in the back is legal, a good Electrican will not stab them if they do any service work, the loose connections come from pluging cords in and out which deterates the little metal tab in the outlet.

    Absolutely. Watch the video - we're pigtailing to avoid loose connections
