Is there a code that states whether a pigtail is required for each outlet or if the second screw on each outlet can be used to continue current to the next outlet in the series?
In the 30 years I've been in the industry I've known no other way than to pigtail. If a neutral tab was to break, the outlets downstream from it would go unaffected with pigtailed outlets. In Australia and New Zealand, outlets are what Americans call "back wired".
The holes have room for two or more wires to be looped through. Wires must be twisted together. In wall power wires can be stranded or solid, but the earth must be stranded. UK sockets are on "ring main", so every socket is expected to have wires feeding into and out of it from both directions. In the UK, it is common to put up to 3 wires into the same screw terminal; I have never seen pigtails being used to avoid putting 2 wires into a screw terminal.
Maybe the screw terminals we have are better able to cope with multiply wires in them. I wan't able to find installation instructions from any of the major receptacle manufacturers. Though I was able to find this video from Leviton a major manufacturer of electrical devices, in the United States. The video demonstrates how to install a receptacle there's also a version on YouTube , and clearly shows the installer using both sets of terminals to make the connections.
To me, both methods have 2 connections that can fail. If properly done, they will most likely have the same probability of failing with terminals being higher in earthquake prone areas. I have never seen a pigtail of wires in a box with a receptacle. The outlet is always used to tie lines together.
I think the advantage is reliability. Having been a certified electrician in california for 10 years, the first thing they teach you in a union apprenticeship is that pigtails save you on future call backs.
The reasoning is this, most receptacles are only rated for 15AMP, and wirenuts are rated for at least 20 on yellows, or greys and probably 30 on reds. So your passthrough is the same as the wire itself. Receptacles are a weak point, meaning that they get torqued, and slammed and pulled. You don't want that to be your splice point. You want your splice on wirenuts, many times receptacles have razor blade stab in's which work well in a time pinch, but not when you are relying on them to carry 20 AMPs to the next 5 receptacles.
If you do use receptacle screws, Don't use the stab in holes at least. One method is the feed-through: uses the receptacle to carry on the circuit elsewhere and the receptacle must be designed to do so note that not all receptacles allow feed-through , the other method is the pigtail one: wires are twisted inside a wire nut. They are both equally safe if done properly. Regarding the codes: that changes from country to country, for example in North America and UK the use of wirenuts marrettes is common but in other European countries marrettes aren't approved.
Depending on the country one is in, electrical components are built and tested differently, rules and practices are different my personal experience is with Canada and Italy for example. Obviously one follows the code that applies to them and inspectors will require whats fitting to the code according to them and their experience.

DA01 DA01 In past homes, that was always done via pigtailing. Active Oldest Votes. Well, I've only owned one home prior to this, so I suppose the person that did that one just preferred the pig tail option.
The electrical inspector told me that pig tails are required. Craig Pigtailing is definitely the recommended practice, but I don't think it's required by code. Craig, pigtails are required on MWBCs always, so if you have those, that might be why. Or it might be a local code amendment. May 1 '19 at Like I said, this is not a wiring method that you're likely to find in a home. Rand Rand 4 4 silver badges 7 7 bronze badges.
It's actually a wiring method that's extremely common in a home's kitchen countertop outlets, to provide the required 2 20 amp circuits. Rarely seen elsewhere in most houses, I'd agree. I used to use mwbc's heavily but as arc fault and GFCI's now have to be just about everywhere I don't use them as much because of nuciance tripping.

Daisy-chained outlets are the worst. Michael Michael 3, 3 3 gold badges 23 23 silver badges 26 26 bronze badges. Unless the failure is in the binding screws, the backing plate, or the break off tab, how does an outlet failure effect downstream receptacles?
Current will pass thru this path regardless of what happens inside the recep. A pigtail has a wire nut carrying the full circuit current and has "teeth" that bite into the copper which is probably more gas tight and resistant to heating.
The PSI of a wire nut is much higher than a binding screw so the wire will deform and make an oxide free connection. It depends on the type of failure, but as Philip Ngai has pointed out, the screw terminal, backing plate, etc. Stabbing the receptacles in the back is even worse, and it is very likely that you'll have a failure at some point down the road.

How does this apply to GFCI protected outlets? This only applies to multiwire branch circuits. The question specifically mentions home wiring and multiwire circuits are extremely rare in home circuitry. And on that note the final line should read "So there you go Also, the entire NEC reference should be made clear before the reference that it is only required in mutliwire branch circuits which is rare and a critical point!

Can you link to the code that requires pigtails or quote the text here, or at least mention a reference number or something so folks can look it up? I agree with Tester. So, that means if you are not using a multiwire branch circuit then you can use the clamps on the devices for the hot and neutral.
The ground would need to be pigtailed on every device but the end of the line. If using a MWBC then you would also have it pigtail the neutral on all devices but the end of the line. Wago, Ideal, and other push-in connectors are UL listed for use and can be used for joints in an electrical installations.
Or you can use wire nuts. The choice is yours. The NEC simply indicates that any connectors or devices have to be listed for that use. Pigtails are not required or prohibited in general. Receptacles with multiple screws are listed for such a use, so you're good there. Similarly, Wago and other push-in connectors are listed for connecting two or more wires together, as are wirenuts - assuming you don't overfill them of course.
You can use the screw or pigtail. I like pigtails because it makes it easier to pull the outlet but if at the max wire fill it may fit better going to the screws. Sign up to join this community. The best answers are voted up and rise to the top.

Basically, a wire is used to connect several wires together in order to keep the number of wires down, a clean area, and allow everything to be hooked up efficiently. Another reason that pigtail wiring is used is to extend the length of wire.
If one is too short for a device, you can use pigtail wiring to make it longer. Many times there are regulations on the size of wire that is being used. Typically you will need to have a minimum of 6 inches of wire when you are hooking up pigtail wiring. There are a few tools that are necessary when you are working on a project that entails pigtail wiring. Some of these tools include wire strippers, linesman pliers, and scrap pieces of wire.
The main thing to point out is that you will need to use that type of pliers specifically for this type of project. The wire strippers are extremely important because before you begin, you will need to make sure that you strip off almost an inch of the insulation. Once you are finished with the process, you will also need a wire nut and cutters so that you can make sure they are all the same length on the bottom and that they are secured together.
Making sure that none of the bare copper wire is sticking out is important when it comes to the wire nut. The first thing that you want to keep in mind, whether you are a professional or a beginner, is to shut off the power to the area completely. Then, once you have shut the power off, double-check it with a tester to make sure. This is a serious step that should not be ignored as it will cause harm to you as well as the wiring and components if you skip it.
Also, check with local building codes when doing any type of wiring. You want to make sure that it is allowed and that you will not end up damaging your home's wiring system or any device. Finally, you may want to try and choose one color wire to stick with each device and wire that you are hooking up together. This will allow you to work with ease and reference them later if there is a problem.
