We have received numerous questions on our past electrical videos wanting to know why 1 outlet might have 2 sets or 3 sets of wiring in the same box. I understand how this can be confusing and a bit intimidating to a DIYer safely taking on electrical projects. I will walk through a few different instances of what to do depending on the type of receptacle you are installing.

I can tell you from my own experience that this young man has the best presentations I have seen. Nice job sir.
I have to say from "My Experiences" This young man @8:08, made his Shepherd Hooks Backwards. You always want to pull the insulation into the screw. You are always tightening to the Right so the wire comes in from the left. Anything else he says is SUSPECT also.
@@Delekham And I can say from my experiences that you didn't listen to or watch the video carefully. In the timestamp you gave, he is not using a hook at all. He is backwiring: leaving the wire straight and the screw terminal has a terminal clamp that pinches down on the wire when the screw is tightened. The back of the receptacle has a stripping gauge so that you strip the insulation such that the wire fully bottoms out in the screw terminal yet the insulation is flush with the terminal clamp once screwed down. Your lack of attention and/or comprehension makes anything else you say suspect also.
@@vitticeps1974 Good reply !
@@vitticeps1974 Touché Sir !
Haters gotta hate.
Excellent. For 20 years, my yard lights came on with my indoor hall lights. I used this info to switch them over to my porch light. Took me long enough
Better late than never 👍
The wire for the yard lights was on the wrong switch
This is the third video of yours I've seen. I'm impressed I've been in construction for 40 odd years . I can build a house no problem. but someone else always did the wiring . I don't build anymore but I still do repairs many of which are electrical . I'm subscribing to your channel and recommending it to any and all home owners whom I work for .. as always ,well done and thank you
I was probably going to have another bland boring and depressing 4am but I 100% have you to thank for the change in mind set . Of all the unimportant drama I could have typed in my search bar I looked up wiring basics and found your channel, I'm like 25 minutes in to your content and feel an overwhelming sense of confidence. I've needed electric work done desperately and now I am going to be picking some things up on my way home from work . Hopefully in 12 hours my life will be a little brighter.. thank you for the wisdom and keep it coming
Hey Greg, happy to help. Be safe and best of luck on your projects.
How'd it turn out😅
Love the way you explain things. Very simple and to the point. No music, no fanfare…if I want to hear music, I’ll take out my trumpet.
Thank you for the info. As a DIYer I've encountered situations like this in our home over the years and knowing this stuff beforehand would have made installing new outlets and switches so much easier. Love those Wago connectors!
I enjoy all your videos. I usually download all the RUclips videos I watch on all channels, so I can watch them as I get time. After I watch them, I delete most of them. But I usually save yours to a folder on my computer. LOTS of great information!! THANK YOU!!!!
Thanks for all your support 👍👍
This was GREAT. Thank you for not just showing me HOW to do this, but explaining WHY (how to track down which is the power in, etc). Very cool.
That is one itty bitty box you shoved that giant receptacle into!
GFCI and USB receptacles can be problematic when you have two or three sets of wires to deal with in a small receptacle box. Sometimes a deeper box can be a solution if there is enough room inside the wall.
With that many wires you need a 20 cubic inch box.
That box is nailed on to the stud so you'd have to cut the nails with an oscillating blade and get a deeper old work box with the wings in there. Messy but doable IF you have enough wire length to work with.
I've done this a handful of times lately, and it's not too bad. You're right that getting the wire back in can be tricky. Would be a great video for this channel.

This channel is a lifesaver, probably literally
We are here to help 🙌
Great info. I really like the connectors. I can’t tell you how many times I’ve struggled with sets of 12 gauge wires trying to get them back into a small electric box only to end up tearing the small box out and replacing it with a deeper box. 12 gauge wiring is no fun to work with! The connectors and outlets are definitely on my immediate shopping list! Thank you.
I cannot recall how many poor twists and attached wire nuts I have come across in my 62 years and almost all were ‘allegedly’ installed by electricians. WAGOs have been used for decades and like all electrical, they should be installed with care.
Be careful, there are some knock offs out there and the quality is definitely cheaper. I always let my customers know before hand because the wago 221 are spendy but worth it when it comes to electrical and safty for your customers.
Thank you very much for your videos. I am working on renovating a house built in 1995 and the electrical wiring is a bit interesting. Some of it does not make sense as far as why certain receptacles are connected and others are not. Your videos are helping me quite a bit. I'm commenting on this one, but I have watched several of your videos (sometimes 2-3 times) to help me figure out the correct way. It has also helped my regarding connectors and tools. Thanks again.
I can't say this enough, this man has made my life easier just by recommending the WAGO connectors. Add in all the other little tips I've gathered from watching, and I feel like I owe this guy an invitation to our next beachside cookout, and a growler of the private reserve.
PLUS, you can probe them (at the back of the Wago) if you want to test for voltage; saves you from taking the "wire nut" off to get to the conductors.
Thanks Jerad, appreciate the kind words and will keep an eye out for the invitation 😁
Does it matter the order the wires go in the Wago
@@JOSECONTRERAS7676LJ - It does not matter because the WAGO connects them all together.
@@manny7886 👍
I just had to fix a plug like this. It had reversed polarity so I took apart to fix. I had no ground wires connected plus my main power was from bx cable to Romex. The wagu lever nuts worked great for pig tailing. The only thing I added was a piece of tape to keep the levers locked while fumbling with all the wires. I was checking videos to make sure what I did was even close to code! Your video series has been very helpful!!
Thanks!As a mason contractor for 42 yrs.,I have installed alot of boxes in the walls,but the electrical was done by the contractor in that field of work, which has left me lacking in my knowledge of electrical issues. Your video,s are very helpful. Txs. James Tillar,AAA MASONRY
Thank you so much, i just installed my first gfci in my tenants apartment. I own an older home and a few receptacles are not grounded. My tenant understands and he is very appreciative
Great video. Everything a person would need to know to replace a receptacle with no superfluous banter! Great job!
Excellent. The three example receptacles are what we encounter in residences. Your explanation was clear and concise. Thank you.
Great video, it's worth mentioning at time 3:45 to power off the breaker, and double check that no wires are live. I test all wires to be safe, because if someone had wired hot & neutral backwards then you can get a hot neutral.
You not understand neutral . Both are current conductors . Neutral is not a ground period of 0 volts . It a pathway for the return of half the voltage and amps to service transformer only. Never use neutral as a ground. A ground has 0 volts 0 amps connected to earth only. Easy to remember by what it called . Ac means alternsteing curent , means goes out and returns like a magnet. Dc = like batterys= direct curent, goes out but not return to service transformer. A service tranformer only trans form a volt with amps at a even count only as 240 volt 10 ampd to a 120 v 20 amps service. It a 2/1 transformer. A pole transformer is a step down transformer at 10000 volt at 30 amps x 240 volt x 2010 amps , it is a 67/1 rating transformer , if house is 100 amp at 240 volts , then it take a 24 or best to chose 1 size bigger 25 kw step down transformer oil cooled is best.
He says it at 1:50 boss
@@treposey4107 yep
I was thinking the same thing Cori. Somebody may have switched the hot and neutral so that a white wire may be live. I always check all wires, including the grounds, and check the box if it’s metallic.
I agree that the way this is presented, it looks like he's digging into the same box that he just identified hot wires in. I know he said previously that power should be turned off at the breaker, and then verified, but he doesn't do a very good job of demonstrating this. Newbies/Beginners might be confused...
Thank you this was informative and helpful. I opened an outlet with the exact configuration you described with 3 sets of wires, 2 back-wired and 1 side-wired, and I wanted to put in a receptacle with a USB port. Learning about Wago lever nuts and making pigtails was also really helpful, and differentiating between line and load is also good. Most times I've done repair I've taken pictures and put the next thing in the way the previous thing was done, but now I realize that's not guaranteed to work or be safe.
This was very very helpful. Thank you for sharing. I personally appreciated your effort👍
I just found an outlet like this in my room and boy did that have me scratching my head. This is very helpful. Thank you.
Thanks so much for your helpful explanation of WAGOs and how they really do simplify multi-wiring.
Your video saved my confusion. Encounter outlet like this & removed all the wires; afterward, put the wires in the GFCI & nothing happened. Spent about 30 mins switching wires around still didn’t work. Reviewed your video to install the hot & neutral on the bottom then the other pairs on the top, bingo everything perfect 👍 again. Saved me couple hundred to hire an electrician. Thx

Really learning a lot with your videos, especially with the WAGO wire connectors.
Great video, I couldn't figure out how to wire in an GFI outlet with the 3 black and 3 white wires. Goggled the question and up popped your video it was so useful and easy to do thank you. 👍👍👍👍
Excellent videos! I just wanted to say thanks for these explanations with all of the technical and minor details! Keep up the awesome work!
After your thorough presentation I'm opting to call an electrician. Thank you for the precautions that you share.
I've been having issues with an outlet in our dining room and this video gives me an idea of how to replace the outlet with one that has a usb plug. Thanks for the detailed information.
Happy to help!
Haven't even finished this video and already I feel the need to say, "Excellent video, very informative and covered all the questions I have now, and had prior to starting my search hours ago. Thank you!" I have subscribed and liked this video!
This was a great video! Very clear video & instructions. We were swapping out a new usb C port outlet and were confused about connecting 3 sets of wires.
That was a very thorough description of the various ways to wire for the home. Thanks!
You have the best instructional videos I’ve seen for common electrical scenarios and I’ve watched way too many
Thanks Blake 👍
Thanks for the video man, great job. I love how informative you are with the complete process with the occasional speed up for those inherently slow parts of the job.
Thanks only video on RUclips showing multiple wires
Scott I’m happy to see you have a great following of subscribers. You deserve it. Thanks so much for the invaluable information. With info from your channel I’m learning a lot…so with your help I safely/successfully wired in gfci outlets in my kitchen and bathrooms. Will be purchasing the materials I need to upgrade old outdoor receptacles. My father built the garage here in 1962 and he installed the outlets and while they are three prong grounded and they work and are weather proof I want to swap them for new gfci and upgraded wp boxes. Thrilled to be a new subscriber here! Mucho gracias! ✌️ - Michele
Welcome to the channel and thanks for all the great feedback. Best of luck with all your upcoming projects 👍
Exactly what I found in my wife's home office. A third outlet was wired through the middle of the run but the grounds were just connected together and shoved in the back of the box with no pigtail to the green wire. I disconnected everything and used 4 point wagos just like you did. I can't believe it hadn't started a fire.
Wouldn't the ground wires only be dangerous in case of a ground short, that is a miswiring of the hot wires to the grounded parts?
As i understand, In normal conditions, the ground wires are not live, so connected or not they cannot cause a fire(until there's a ground short somewhere on the line and the ground wires become live, then dangling live wires can cause arcs, or electrocution).
Exactly what I needed, thank you! Was replacing an unnecessary switch with an outlet, but one of the 3 wire sets in the box registered a low flickering light on voltage tester - so glad you said that’s common and not a hot line. Great video all around!!!
They call it ghost voltage.
Love these videos! Your explanations are so thorough. Really helps new DIYer's like myself understand everything that is going on. Thanks so much!
Great tutorial. Loved the tiny bits of knowledge you pepper in.
I just found your channel and really enjoy your videos. They really are informative. Keep up the great work!
You have a very clear way of speaking and explaining these things. Perfect for DIYers.
Thanks Andrew!
I solved a persistent problem I had dealing with a burned out GFCI finally. It was a line/load situation and It was impossible to tell which was which because the insulation was gone back up under the insulation. Anyway, I watched this video (which really helped somehow) and after two attempts at re-arrainging the wiring for the outlet I was able to get the testing plug to register CORRECT. I am grateful to this video for triggering something in my brain that allowed me finally master this situation. The pipes won't freeze up, I fixed it. I had gotten continuity back, but had problems with hot/neutral reversed and tried to find how to know which was line and which was load and which one of those two was wired wrong.
It was crazy because there was basically no color descernable on the burned ends. Alot of hit and miss, turn it on, turn it off, Something clicked after this video and it's done. Hooray.
Thank you for this video! I was installing a new outlet with USB and didn’t know about using the Wago connectors. Thanks again!
Thanks for the tutorial! I was able to replace my old outlet that was humming and successfully do it the first time
I have to say: your presentations are excellent. They are clear and concise. Very helpful.
Wonderful video. Clearly explained the situation and offered helpful courses of action.
Thank you! This was very helpful (:
Just replaced a three way combination switch receptacle with a receptacle and wanted to double check what to do with the multiple wires.
Great video, Thank you so much for covering various wiring set ups.
I'm so glad I found your video because I just couldn't figure out what to do with those extra sets of wires.😅Thanks a lot!!

It's a credit card scam
And don't you just love it when a homeowner does the wiring themselves and uses what ever color wire they have available? I helped my best friend change an outlet that was also connected to an upstairs outlet. The home owner used green wire for hot blue for negative and yellow for ground. We were able to replace the outlet because my best friend saw how the wires were connected before we began the work. It was a nightmare.
Really well done video all around! It's clear, well articulated, steps are not skipped, and I feel like I can safely tackle this!
This video has absolutely assured me I am doing this correct. Very good job explaining things this has really helped!!
Thank you for the idea on the connectors is so much better than using wire nuts which I normally would tape to make sure they don’t come out God bless and stay safe
Thank you. Great video - best explanation of how to do this that i've come across.
Great video, thanks. Looks like pigtails with wagos is the best way to go in all three cases.
I needed to see this! Thank you! Great video! 😌
Excellent video! This explains a lot of questions for me.
Excellent work sir. I just started watching your videos and appreciate the care you take to explain the work you do. That being said, I would like to request a video that explains multiple switches. I have a bathroom with a light and a fan, and there's two switches for each one (One inside the bathroom and one outside). The dude that did them didnt know how to hook them up properly, so now both light switches work as expected, but the fan requires one switch to be on for the other fan switch to work. I have the same issue for another room with a ceiling fan. Two switches for the fan. Switch 'A' turns it on or off, but the other switch 'B' only works if switch 'A' is also on.
It's been 7 months since you've posted your question, so I don't know if you found your answer yet, but you can find diagrams all over the internet on 3 way wiring methods. 3 ways are a little more complicated to explain because of the different wiring methods used by electricians. I can tell you that this issue is due to the travelers and the common wire crossed. Three-way switches have 4 screws. One black, two brass, and one green. The black is common, used for the power or switchleg. The brass screws are for travelers. The two wires traveling to both boxes. Usually, they are red and black wires. The green is the ground. Hope this helps.
Always good videos.
Would you mind doing a video on how to identify different types of common circuits based upon what you have in the box?
(multi-wire, pass throughs, switch legs, switch loops, junctions).
Also, after watching this. I think it might be a good idea to have a video showing how to determine box fill.
Maybe show the different types of boxes, (Plastic switch boxes, 1900s, 11Bs, 8Bs, metal work boxes), the difference between ganged and non-ganged work boxes. Then show where you can, and can not have certain things, based on size of the box, amount of conductors, and size of the device.
😊 my ym😊 lobbies up h
a recent home reno with having to relocate a triple gang box of switches including three way and power in and outlet, take a pic or two, and colour code with electrical tape each pair of wires marking which switch/outlet.. when pulling/feeding/moving the wire and boxes to new outlets and switches it makes for a very quick rewire without having to retrace everything.
This video was perfect for my conversion of an old two prong outlet to a three prong / usb outlet. In my case, I was able to ground from the new outlet to the old metal box.
Thanks, you just cleared up all my confusion.
As a pro for over 2 decades your the 1st person on RUclips that I have seen recommending the Pigtail. You should've explained why it's not a good idea to wire an outlet with 7 wires on it (including 1 ground). But let me ask you "if that outlet with 7 wires was to go bad which they do how long would it take a reg Joe to troubleshoot"? You should ALWAYS Pigtail outlets. Saves you time and money plus your wallet.
Theoretically, it doesn't matter... the bus bar and terminal are solid brass or whatever material connecting all the wires. They can't really go bad, on a standard receptacle as they're monolithic chunks of metal. (Not including shitty backstabs.) The outlet itself may be junk but the rest of the circuit should be fine since they're all still in parallel wiring configuration whether pigtailed or connected at the receptacle.. One exception would be the GFCI but it's expected to disable all loads downstream of it if it goes bad as that's how it is designed.
Some electricians say those Wago style connectors don't work or will fail on you. I've never had an issue. I love them.
That was beautiful work! Some of the videos I watch, make me realize how beautiful and creative doing electrical work can be.
This is such an awesome video!! I'm going to scour your channel to see if you have a video on this same exact situation but with AL to CU connections! 🤞🏽 Thank you!
Very helpful idea and nice explanation..
Great video! I’m about to wire the outlets in my bus so I’m glad I checked this!
One other maybe common situation - or at least I've seen it - is where the outlet has been split to have 2 15 amp circuits (used to be common in kitchens here) or where one half is switched and the other is always powered. These situations could result in surprises that weren't mentioned in your video.
They'll figure that out when the breaker keeps kicking
I agree, if wired wrong you could also be bypassing the switch
I have split receptacles in my kitchen. 240 volts between the two hot leads....
wait this is the problem I'm having lmao help!
Super helpful, thanks for posting this.
Thank you. Very informative.
This is the video I have been looking for! Thanx for posting!

Thank You so much for sharing your knowledge! God bless you!
Happy to help 👍
Great videos! You do an excellent job explaining things. Love the channel, subscribed.
Thanks Nick, welcome to the channel and I appreciate your support 👊
I too think you should advise your viewers that by using that type or the GFCI receptacle, there really isn't enough room in the standard box for all those wires assuming using the WAGO and a 4th set of pigtail wires.
I think you are right on, especially when you notice the vents this fixture has in the back and the sides, I'll bet there was a very detailed instruction with this fixture explaining the volume of the box required and number of conductors allowed in each volume of the potential boxes.
We'd behooved to learn about AFCI GFCI combination receptacles AND / OR breakers, AND with USB. At what point does it end, that we have to protect people from themselves ? I would argue that the breakers are the best option, so they protect the ENTIRE circuit and not just the individual or branch circuit. For example, when I trip the GFCI, in one instance of a particular room, it takes out all the outlets in that room but not the lights. In another room, it takes out all outlets AND the porch light, AND the ceiling lights as if I tripped the entire breaker, however, other things attached to that same breaker are still live. In that scenario, I would argue that it is best to have both AFCI GFCI combination receptacles with USB AND AF-GF CI breakers too. This will offer extra protection, or be a fail safe, and it will also help determine which specific circuit has the problem.
If it were up to me, all basic house wiring would be 10 or 12 gauge and absolutely NEVER 14, except when attaching ONE outlet or ONE switch. You can go from thicker gauge to thinner but not thinner gauge to thicker. I would also like to see two electrical boxes. One with a removable decorative plate below the outlet itself, where all the splices are. Never in the box of the actual switches and receptacles. There is a very good reason and use for that, but also goes along with METAL (Steel) boxes. Plastic and nylon boxes should be banned. But that's a different rant for a different time. It has to do with grounding and heat.
I would also like to see each outlet, and each light fixture on it's own breaker. So you might have 4 or 5 breakers for one bed room, or 3 breakers for one bathroom, etc. That ensures you always have power when you need it, and can safely work on another circuit, without taking down half your house. I would even further that by saying that each receptacle that has two outlets also have their own feeder of 12 gauge wire minimum. When I talk about wire (Romex) I am meaning COPPER. NEVER aluminum. However I think the lever wire nuts or even the push ins would be better for joining copper to aluminum. Further still, I would like to see that instead of receptacles with 2 outlets, they only have 1 outlet, with the top half being a switch to control the bottom half. This is for safety AND convenience. These days, you cannot truly TURN OFF, anything. When things are OFF, they're still drawing power in most cases. When you turn something OFF, it should be OFF, not in standby and not drawing any current at all. It should be truly off, and breaking the connection ensures it. So anyway, that's my stance on these things. I'm sure the next generation will be talking about even more B.S. for safety because we live in a society that have people that are SO STUPID, they don't realize that using a blow dryer will NEVER get their hair dry while standing under a shower. Hence the warning tags and the government needing to protect stupid people from themselves. It is a good thing in some cases, but in other cases, it's taken too far, and no doubt it is so that corporate America can get richer off the poor.
Thank you much I like very much the way you take your time to Details
Unless line/load on a GFCI or having a split receptacle, I would always pigtail multiple wires in a box. Therefore you are eliminating the confusion for the next person to open the box. Also it is easier to tighten down one wire on a screw rather than 2 or even 3.
WAGO. FFS.
Wago or not, this is simply good wiring practice. Why loose everything downstream if there is a problem in the future. Troubleshooting can be time consuming as it is. Always pigtail if it's just feeding through. Always. Period. Don't even get me started on back-fed outlets.
@@charlesford157 Could you explain why it would help trouble shooting by pig tailing vs having both wires on the receptacle? Trying to learn as I was planning on putting all wires into my receptacle vs adding another wire and pig tailing. Thanks!
@@raiderxx It's just like anything else. To be honest this pigtail method is really the result of back-wired outlets behind just literally stabbed in the back. One wire gets loose and you lose every device down the line. Typically yes, using both sets of screws on the outlet is fine, but what do you do when there is 3 wires? Adding another wire to a screw is a bad idea. So to keep things simple, if you pigtail all problems screw or back-stab related are moot. If you have a problem you know right where it is.
Thanks for the info brother, this will help people do things right
I am very serious when l say, thank you for a easy to follow instruction
Awesome tip i have a plug like that with multicable wires. Thanks
Thanks man I was looking for this exact explanation 👍🏼
Will be doing these very soon.
Good information. Very thorough.
Wago is pronounced way go.
Great tutorial. Thank you!!
I have a four-gang box in an extension off my kitchen that has a three-way light switch where the other switch is on a different circuit. That was a fun one to suss out.
like a puzzle 😅
Great video very well explained.
Thank you sooooo much for this!!! I was stumped
You bet!
Thank you for the video, helped me with a few things... thumbs
Over the course of several years as outlets in the house wore out leaving cords that wouldn't stay in the receptacles I found many of the outlets to have been wired with the back stabbing method...as I've replaced them, I have been using those commercial type receptacles, they make a very easy to install replacement and absolutely no back stabbing I hate that, I'm not an electrician but can tell those wires are not very secure.
I just got finished rewiring a bunch of lights, switches, receptacles, and adding receptacles, lights and switches...wish I had those WAGO connectors...I have ordered some, and will be cleaning up a couple junction boxes with them for a much nicer mess of wires LOL....I have one right now that I need to replace the junction box as its way too small, not sure who put it in but its a very shallow box, so trying to get the wires into it is, well there's no cover on it at the moment. I'm thinking of breaking up whatever is in that mess and putting in a 2nd junction box, and I'll be using the WAGO connectors from now on, much better storage utilization than bulky and sometimes questionable wire nuts.
