The BIGGEST Mistakes DIYers Don't Know They Are Making When Wiring Receptacles | How To

now when it comes to installing receptacles or other devices like them i've seen a lot of very common mistakes or at the very least some very poor practices when installing these types of devices so there's quite a few of them so let's go ahead and jump right in let's go alright so the first mistake i'm going to go over when discussing installing these receptacles this may seem very basic but you might be surprised how many people don't know the difference as far as where the wires are supposed to go so on this side here you'll see we've got these gold colored terminals if we flip it over the other side we've got these silver colored terminals the gold colored terminals are going to be for your hot wire typically it's going to be a black wire that's coming in that's supplying the power and that's going to be connected over here to the gold side the neutral wire which is the white wire is always going to go over here on the side with the silver colored terminal screws if you were to put your black line wire on the silver terminal and your white neutral wire on the gold terminals this is referred to as reverse polarity now the reason why that's so dangerous to where if you have the line or the electricity wired into the neutral side with these silver screws is because it's going to create an unsafe receptacle it may work but you are running a risk of having a short circuit or a shock or even possibly a fire so just remember that black is always to gold the white neutral wires are always to the silver terminals and green wires and bare copper wires like this one here are always the ground wires and they will always go to this green ground screw here all right so for this next mistake this is a very common residential receptacle these type receptacles require for a hook to go around the terminal screws and then it gets tightened down but one of the really big mistakes i see when people are installing these types of receptacles is when they take their wiring they're stripping off way too much insulation so when they take their hook and they wrap it around the terminal screw and then they go to tighten it down you can see this copper that's extending on past the terminal screw by quite a bit and then also past the back of the receptacle the problem with this is once this is all tightened up and pushed into the back of the box what could happen is possibly your bare copper your ground wire could rub up against this hot wire here and then it's going to cause everything to shore out you could also have instances with arcing depending on how everything is in your box which is obviously something that you don't want that could ultimately cause a fire conversely i've seen people and this is a little bit of a dramatization but i have seen them like this where they cut too little insulation off that hook when they wrap it around that terminal screw as you can see even though that hook is around that terminal screw once we would tighten down the terminal screw on top of it if we flip it here to the bottom side you can see that insulation is underneath of the head of that terminal screw well when that terminal screw gets tightened down and it clamps down this wire it's going to be making a lot of contact with that insulation which is obviously wider than the copper portion of the wire and you're not going to get a good connection there so you also are going to have a bunch of issues here the outlet itself may not work or it may work intermittently or you could have a case of where it short circuits or causes overheating and a really easy way to check and make sure that you have the correct amount of insulation stripped off of the wiring is you can use a strip gauge they're on pretty much all of the receptacles that are out there and you can just put your wiring up into that strip gauge just to either confirm that you've stripped off the proper amount or if this wire wasn't stripped already you can just lay it up in there make a mark and then strip it from that mark off and you know that you're going to have the perfect amount of insulation removed from the wiring in order to have that good connection and so this is what a good connection would look like all right so talking about the wiring being connected to the receptacles that leads me to the next mistake that i'm going to talk about and that has to do with these hooks again and so i'm just going to put this hook over this terminal screw and then i'm just going to go ahead and tighten that down all right so does anybody see the mistake with this wire on this terminal screw yeah it's put on in the wrong direction it's being put on in a counterclockwise direction and the problem with that is if you can see all this copper up here at the top and then here at the bottom it's not awful but what ends up happening if you put your wiring on in a counterclockwise direction you may have seen it as i was tightening that down it's actually going to promote the wire being pushed away from the terminal screw so it's not going to be in nice and tight in the middle of this terminal screw which could lead to not as good of a connection as you would want so what you'd actually want to do is you'd actually want to take that hook and instead of wrapping it around in a counterclockwise direction we want that hook or that loop to go around the terminal screw in a clockwise direction as i tighten down the terminal screw it's going to promote pulling that wire in closer to the center of that terminal screw which is going to give us a much better connection so as you can see it's pulled in here nice and tight and we have a really nice solid connection here and this is especially true for this stranded wire here it's going to be promoting or pushing each one of those strands out away from the terminal screw but if we take that same strand of wire and wrap it around in the correct direction the clockwise direction you'll see that it actually wants to pull it in closer so as you can see all those strands are in there much tighter we don't have any of those stray strands that are basically reaching up to this second terminal up here everything's in there nice and tight by going around in a clockwise direction now really quickly if you're finding value in this video if you could do me a huge favor all that i ask is that you hit that thumbs up button right down below or leave a comment down the comment section letting me know what you think of the video so far it really does help the video out to spread out to other people and hopefully be able to help them out as well i really appreciate it let's get back into it all right so for this next mistake or really a very poor practice and this is one that i've seen electricians do because my house was wired in some places like this since then i have corrected it because i really think that this is a really poor way of doing it is on these residential outlets if we flip it over here to the back if you see these four holes here this is where you can insert up to 14 gauge wire into these holes to connect the wiring to the receptacle itself this is known as speed wiring also known as backstabbing and the way that this works we've got our silver terminals here and a white wire all you have to do in order to make this connection is push the wiring into one of those holes and once it seats as you can see it doesn't just pull out and while this seems like a really great way of doing things because it is so quick and easy to do there's a lot of problems that can come from this now if you're going to have a problem and you have a defective device you may see issues right away other times it may take time in order for issues to develop and the reason that it may take a while is that the more that the device is used the more that it warms and cools the more that it's moved around that little piece of metal that's inside that's making connection and holding this wiring in may become loose and if it becomes loose over time what can end up happening is the wire starts to back out and may fall out completely if it doesn't fall all the way out and it just starts to have a really poor connection well then you could have arcing and heating and a bunch of other issues and to kind of illustrate this wire being backed out as you can see it's in there nice and tight you need to depress there's a little tab inside of here usually use a screwdriver to depress it and then pull it out if you wanted to remove the wire i'm going to show you right here where i can remove this wire without depressing that tab just by pulling on it and twisting the receptacle back and forth and it's just that easy for that wire to come out so for this next mistake this is a big one as you can see here i've got two terminal screws and just imagine that the whites both of these terminal screws are taken up as well and they're wanting to connect another receptacle or another device of some sort and they want to use this as a way to tap into the circuit well what they'll end up doing is they'll loosen one of the terminal screws they'll leave that wire in place they'll take their new wire and they'll put it in on top of the wiring that's already there so that's what they do they leave their wires that are already there in place they take their new wire coming in so they can connect to something in order to power a new device and then they just sandwich the two together underneath of one terminal screw these devices are not made to have more than one wire under the terminal screw so this is against code and it's also incredibly dangerous to do over time what can end up happening is since we don't have proper pressure from the terminal screw on the wiring and there's variables to where these wires can move one of these wires can eventually fall out from underneath of the terminal screw which then also has the other wire being loose and then that can cause all kinds of problems with the minimum of the receptacle not working or damaging it all the way up to causing a fire it would be far better to avoid doing this at all and just use some pigtails in order to connect all of your devices and the new device that you're wanting to install the next thing i want to talk about as far as installing these receptacles or devices that are like them that is really going to make things a whole lot faster easier and make sure that your connections are going to be as tight as they should be is it comes down to the tools that you use now a lot of people are using their standard phillips head screwdriver in order to loosen and tighten the terminal screws on the receptacles and while a phillips head will work it can also cause issues if you get down to the point of where it's becoming hard to turn if you go to keep trying to turn it look at what happens the phillips head wants to just kind of come out of that terminal screw and that terminal screw can still be tightened down a little bit more so with a phillips head you can't always get this tightened down as much as you should and then there is the robertson bit or a lot of people call it the square bit the robertson bit is what i've been using for quite a while now because it is extremely effective at tightening down these terminal screws but there are a couple of options out there that are actually better than the robertson bit so what i'm using now are these two bits right here over here is milwaukee's ecx bit and over here is klein's combination bit if you see here you've got this long blade here kind of mimics a flat head so you can get a lot of nice torque on that terminal screw if we flip it up here to the top side you can see it's kind of squared off so it's more like that robertson bit so you can get right into the middle of that terminal screw and also help to add to that torque and get a nice grip on that terminal screw so just to kind of give you a visual as to how much better these work this is a standard phillips head so i'm going to get it down to where i can tighten as much as possible with this and now it's popping out so let's see if we can't take one of these newer bits put it in there and get it to tighten down a little bit more so as you can see i was able to rotate it a little bit further than i was able to with the phillips head and it was pretty easy to do so i have links for both of these down in the description down below now if you like electrical projects or other projects for around the home i'll post some links right over here of some videos and playlists that you might be interested in now i hope this video was helpful and maybe you found it to be interesting and if you did if you could do me a huge favor hit that thumbs up button right down below and of course if you have any questions or comments at all you can leave those down in the comment section and i'll catch you all in the next one
