How To Wire A Sub Panel - VERY DETAILED INSTALLATION! Start To Finish

in this video I'm going to show you how to wire a sub panel and if you're new to this channel my name is Joshua channel is all about DIY to save a ton of money so be sure to subscribe ring that Bell so you get notification airtime release new video and Hammer that like button for me it's always from turn for making this video so we got a lot to go over today so let's get started the subpanel that I'm going to be installing is a 100 amp 24 space 48 circuit this has a main breaker on the panel and this is for interior use and it's going to be a flush mount made by Square D and this is the home line version with the plug on neutral and if you're interested in purchasing this panel I'll put a link in the description below so you can check it out for yourself to begin the installation I'm first going to unbox the sub panel and show you the contents inside very first thing I have here is the cover for the panel so this will be installed after we have everything done here inside the first thing I got here are the lug covers in my jurisdiction I must cover these lugs so that you're protected if you're working inside of this panel this is the bonding screw if this was a main panel installation straight from the meter and there was no disconnect involved I would be using this bonding screw but because this is a sub panel I got to separate my grounds and my neutrals so the bonding screw is not needed here we got the owner's manual and it looks like we got a assortment of Breakers here it looks as if we got a double 30 a 20 a 20 a 20 and a double 30 here so these are not the arc fault breakers these are just standard Breakers that come in this box just so you're aware I am the homeowner here wiring Moon panel so I already pulled the proper permits and checked my local codes and I'm going to follow them for this installation so not every jurisdiction can you do your own electrical work so always check your local building codes before performing any electrical work here is the stud space in which I'm going to be installing the sub panel obviously the sub panel is going to be up here higher but I just wanted to show you this is the wire coming in for the sub panel and I made a video installing the conduit going to my house if you want to watch that video I'll put a link to it in the upper right hand corner of the screen and it will show you exact exactly what I did to get all this here and while we're talking about it this is conduit going over to a workbench here in the future when I do that so that's going to be going for a standard circuit then I got this plastic pipe here that's my pecs going to my house and then I got these data cables for my security cameras so for this video we only need to focus on this part in wiring this to the sub panel we're going to work backwards from installing the sub panel then I'm going to show you connecting everything inside the main panel and junctioning this wire to the wire that's coming out of my panel in the crawl space because I'll be screwing this panel to the studs in order to secure it as you can see right here there's a knock out that I gotta knock out in order to drive the screws in through the panel and then into the stud so I'm just going to take a screwdriver hold it right on that knockout and go ahead and punch it out and it's always helpful to use a pair of needle nose in order to break the final piece of metal out of the knockout and there's one in each corner of the panel so I'm going to remove all four of them first foreign and now because I'm installing my panel upright like so I need to get a height measurement in order to figure out the exact height of my conduit before I install it so I'm just going to measure from the top to the bottom and I got 26 inches so now I know where the panel is going to be sitting in order to install my conduit I'm now going to Mark the height of my panel in the stud space per coat of my area I cannot have a breaker higher than six foot seven so I'm going to measure up on the stud six foot seven so just to make sure I don't go above that when I'm setting my panel so six foot seven is up here and my panel is only 26 inches tall so if we measure down from that that puts us at right here so I can easily come down a little bit in order to install this panel so the bottom left panel I'm going to place right here so now we'll know where to cut our conduit to before we set our panel I'm now going to measure off the floor to that Mark we just made and I got 50 and three quarters inch so I'm going to come over to the stud in the stud Bay in which it's going to hold the panel and Mark that on the stud I'm now going to take a straight edge hold from Mark to mark because again that's roughly where the bottom of the panel is going to be and then just measure up down in the conduit in order to see the distance which we need to cut it so we got 43 inches I now got cut my conduit 43 inches the conduit going to this sub panel is schedule 42 inch and this is for electrical wire and as you notice I measured down from the Bell so the bell end just requires a straight piece to go into it in order to go up to the panel now if there was not a belt in below then we would be sure to cut it off this end the head the belt end so it will slide over the straight pipe but again in this case we're just cutting it right off the other end that is not build like so and there's all kinds of different fittings for conduits so in this case is a simple straight run I'm now going to Simply measure 43 inches off of this end and you can cut this using a miter saw or in my case I'm just going to cut it using a sawzall with a metal blade on it a metal blade gets a little cleaner cut but a wood blade would work fine too you just got to be more careful [Music] all right I'm just going to take my knife to cut the burrs off the end I'm now going to take my soap panel wire and fish it through the conduit and I'm going to go over the details of this wire here in just a moment once we get up in the panel but another thing too A lot of people frown upon fishing the wire up through the conduit and then gluing it because you can get glue on the insulation of the wire and it could possibly melt the insulation so if you can avoid it runnus rope and then pull the wire up later I've already ran the wire so I'm just going to put together like this so I'm going to be sure to put the glue up here to where it doesn't get on the wire but I can always pull it up and inspect it in this case to make sure it didn't get on the wire but I'm going to put a liberal amount of glue here and slide it over that Bell and the glue I'm going to be using is just standard PVC cement as you can see when the conduit is placed in the concrete it wasn't going up perfectly straight so I'm just going to take a piece of strapping and flex it back where it belongs so it's held in place so I can set my panel easier this is the adapter that's going to come up through the panel that's hooked to the conduit so I need to know what size knockout to knock out in order to compensate for this adapter so as you can see this right here needs knocked out in order to compensate for this so I'm just going to take a screwdriver and punch that out and then I'll be prepared to put this on the panel now that's going to fit right up through there like so I'm now going to take the PVC cement and glue this on to that conduit I'm now going to use screws with washers in order to Anchor the panel for now I'm now going to place the panel on top of the conduit I'm now going to use a two inch steel lock washer and lock that on to the panel next I'm going to take a two inch plastic bushing and thread over the adapter I'm now going to take my tape measure and make sure the panel is sticking a half inch past the stud in order to compensate for drywall and now I'm going to place a screw through the Knockouts that we knocked out earlier to secure it to the stud foreign take a level make sure we're setting Plumb and it looks like that side needs Drew over a little bit more and loosen this up some all right that looks really good also I'm going to check just to make sure we're level and yes that looks really good so our panel is sitting exactly where we want it right now it's now time for me to go over this wire that I ran from the crawl space of my house to this panel of the detached garage so if we take a look at this wire you first realize that there's no sheathing around it other than each strand is already insulated so this is a stranded wire and it's rated to go in conduit and in fact this is number two aluminum wire that is often used in Mobile Homes believe it or not so we got a neutral wire here we got our ground wire here which is indicated with the green sheathing and the neutral wire is indicated with the white stripe and then we got two hot wires here and here so this is where the juice is going to come in through and this is what's going to energize the panel so so with that being said if we were not in conduit coming straight out of our panel like in the house it would be encased because it wouldn't have to be inside conduit because the conduit was for running underground so now that you know a little bit about the wire coming from the crawl space of my house let's hook this to this panel I'm going to first begin by pulling these wires up through the conduit further and just so you know this wire clearly is not hooked to the panel yet so it's not live but I just figured I'd mention that I'm now going to address one wire at a time the first wire that I'm going to address is this neutral wire in order to strip the wire I'm just going to take my utility knife and just strip off about three quarters inch of the casing in order to do so I just got to run my knife right around the casing like so and then it's going to cut down to the wire but you don't want to apply too much pressure because you don't want to cut in into the wire just enough to score the casing really well now that we got the casing scored now all we got to do is simply take our utility knife and cut into the piece of casing that we are trying to strip off like so and then after you got a good cut on it all you got to do is start prying on that casing in order to remove It Off The Wire and then once you get started just peel it right off like so because this might be a little more than three quarters inch I'm just going to cut a little bit off of it this neutral wire will be installed in this lug at the very top and this is going to cause each bar here to be the neutral bars so now all I gotta do is back out this screw with a flat screwdriver first and before placing the wire in the lug I must first use what's called no locks and this is an antioxidant compound because anytime you use aluminum wire wherever it is placed touching other metal it could oxidize this will help stop the oxidizing process so I must first place this on the end of my neutral wire I'm now just going to put a liberal amount of the Noah locks on before I place it in the lug I'm now going to fish the wire up through the panel and go down into that lug now once we're in the lug like so I'm just going to tighten it right back up in some areas may require you to torque these screws down but in my jurisdiction they never checked that so I'm not going to worry about it all right so that one is installed and now we're going to do that same process that we did here to each one of these for the hot wires in order to address these two hot wires it does not matter if this one goes on this lug or this lug or vice versa they can be either or so I got to follow the same process that I did the neutral wire except doing it with these black hot wires and that's all there is to hooking the hot wires in a neutral up I'm now going to bend these wires to get them in the panel nice and neat [Music] all right those look really good and now I'm going to address this ground wire before going any further I got to install this Ground Bar and you can find this in the links in description as well if you'd like to check it out it's very easy to install this Ground Bar as you can see there are holes already made on the panel and there's two screws out of this Ground Bar in order to have an area to screw it right to the panel and it came with these two Phillips screws in order to do so so I simply just got to screw it right to the panel in those two holes foreign [Music] that's why we got to separate our grounds from our neutrals I now got to land this ground wire in this grounding bar so in order to do so I'm just going to fit it around to where it goes and then I'm going to cut it to length to where I can place it in that ground bar so I can cut it it looks like about right here so I'm going to go ahead and take my linemans and just snip it off and then strip the sheathing and place the no locks on it I'm now going to back out this screw and install it right here all right I'm going to tuck that back in there like so and now our ground wire is connected to the panel I'm now going to show you how to ground this sub panel so when it comes to grounding a sub panel because this sub panel is in a detached garage meaning it's not in the same structure as my main panel of the house so because of that I gotta put a ground rod outside of the garage and hook the ground rod and the sub panel up together using number six bare copper and if the sub panel here was in my garage that's attached to the house I would not have to do this part because it would just use the same grounding system as the main panel so because it's a separate structure per code in my area I got to run a ground rod and ground it separately so with that being said I'm going to take this number six bare copper and hook it into that grounding bar and then I'm going to run it to the outside before hooking the number six bare copper to the sub panel I'm first going to make a run out to the outside to where the ground rod is going to be first so that way I don't have to run the whole row up into the rafters to get it to the destination so I'm going to first begin by taking a drill bit that's just slightly larger than a number six copper and drilling it right up to where it's going to enter into the rafter space because this run of bare copper is relatively long it's over 30 feet so because of that it's fairly rigid as you can see it doesn't Flex very easy so I'm going to go ahead and unroll several feet of this before trying to fish it up to the destination I'm not going to fish my ground wire out to the outside and something really important to note here in some jurisdictions you must encase your ground wire inside of conduit but in my area it's not something that is a code so that's definitely something to keep in mind so with that being said I'm just simply going to run the bare copper not in conduit out to the outside [Music] I'm here on the outside and I know my ground wire is going to come out 51 inches from the edge of this wall so I'm going to measure over 51 inches which ends up being right here so I'm going to try to drill up on an angle to go inside that stud space and keep it down here below the sheathing just so it's easier to hide it under the siding I'm here on the inside I'm now going to try to push it through that hole felt like it just went through right there all right I'm now going to pull that through the ground rod that I got to place is a 5 8 inch diameter and it's eight foot long and I got to stay relatively close to the structure I like stay about a foot and a half or so away from the structure and then I'm going to drive it straight down into the ground and what I'm going to be driving it with is a hammer so this is as you can see a big hammer and you can get a rotary hammer drill with an attachment on it and that will cost you several hundred dollars so I like a good workout so I'm going to use the hammer and drive this straight down into the ground you definitely want to wear gloves while you're doing this process but I have to get up on a stepladder in order to get the ground rod started then clearly once I get to a height that's acceptable for a five foot ten foot person then I can just resume off the ground [Music] [Applause] [Music] [Applause] [Music] [Applause] [Music] this is a workout man I like it [Applause] in order to connect the ground wire to the ground rod I must use a 5 8 inch ground rod clamp and this is going to be placed over the ground rod now the reason why I like to place the ground rod clamp on now is because as you can see the top of this ground rod is starting to get mushroomed and if it gets mushroomed too much it's very difficult to get this clamp on so I like to put it on while I'm towards the end of driving the rod so that way when it mushrooms out all the way it won't be able to be slid on as you can see even now it's already getting difficult so now that's placed over the rod I'm going to continue driving the ground rod in all the way until we're flush with the ground or deeper I'm now going to take the bare copper and just place it right below grade going right to the ground rod and now when I get to this point I'm just going to bend this in a nice L shape like so so it's facing down and now I'm going to take my clamp and I'm going to fish the ground wire right into the clamp on this end like so I'm just going to put a little extra hook here that way it keeps it secure and now I'm just going to take a half inch socket and tighten down this clamp and you don't want to over tighten this because you can break this so just snug it up really well that's all there is to connecting the copper to the ground rod and before you drive your ground rod clearly make sure there's no underground utilities here you could call Miss Utility if you really wanted to already knew there wasn't anything below here but that's something to keep in mind when driving your ground rod alright so now I'm going to keep this exposed until it's inspected I'd like to stress that because this is a sub panel it only requires one ground rod now if this was for a 200 amp house it would require two ground rods just so you know I'm now going to get the other end of the bare copper wire and get it fished down into the panel I'm now going to land the bare copper wire into the grounding bar now the sub panel is officially grounded I'm now going to install these lug covers over these hot terminals once the power is on these terminals will be hot and exposed if you open up the panel so this will just help add a little extra protection in the event of with your working in the panel I'm now going to prepare the junction box before we go into crawl space to Junction together the two number two aluminum cables in just case you're curious the reason why we got to put them in a junction box is because we're transitioning from stranded wire that was meant to go into conduit to cased wire that was meant to just be ran under the crawl space that wasn't meant to go in the conduit because it's not rated to so I had to have a way to transition from one type to another so I had to do a junction and with that being said too I wasn't sure exactly where I was going to put my garage around back so I wasn't sure exactly how much I needed wire wise so that's why I'm putting it into a junction box I did already install the clamp that was for the number two aluminum coming out of the panel now what I'm going to do is drill out a two and a quarter inch hole to compensate for this adapter so that this conduit can go up into this junction box I'm going to be cutting the hole out with a 2 and 3 8 hole saw in the two and a quarter inch measurement is the diameter of this adapter that's going to go into this junction box so I know I'm going to end up hitting about right here towards the center of this junction box so I'm going to drill this out right here I'm now going to go ahead and open this up and retrieve that piece I'm going to dump out those shavings I'm going to clean this up a little bit using my utility knife and now I'm just going to install the adapter similar to how we installed in the panel box slide this up into here like so and then we're going to take a lock nut and lock nut that on like this and I'm now just going to put this bushing on like so from the elbow to the junction box I need 13 inches from the Bell on the inside up 13 inches so I'm going to cut that off now I'm just going to quickly get the burrs off with my utility knife I'm now simply going to glue all of this together I need to make sure I'm sitting to where this is square as if is laying against the wall all right now that we got this glued together let's go install it in the crawl space I'm now down here in the crawl space I'd like to point out a couple things here this is the number two aluminum that's going over to the sub panel we just wired and this is the water lines and the data cables that you've seen underneath of the sub panel just to point out a few things so first thing I need to do is figure out exactly where I want for my junction box which already did and that's why I already put the elbow on and everything like I showed you already so the first thing I do is install a PVC body right here in order to angle this number two aluminum to where I want it so here it is slid over the wire and now I'm going to glue it so that I can pull it this way through up to the junction box I'm going to begin by gluing this so it's pointing in Direction that's laying now and already cleaned this off with sandpaper and got nice and rough and again because the wires already ran you got to make sure you don't get any glue on it so I'm not going to be too liberal with the glue here just enough to get this secured I'm going to slide this on and angle it where I want it that looks really good right there I'm at a 90 degree going left off the wall I'm going to glue this together so that we're sitting right here and we're sitting nice and Plumb by the time said and done so I'm going to glue it to the body now and then just hold it there in place until I get screws in it I'm going to use my hammer drill with a masonry bit and anchor two inch tapcons in each corner where you see a hole that is located on the junction box I'm now going to remove the cover off of the junction box I'm now going to take the end of The Wire that's coming from the sub panel and fish it right through this body and then exit up here into the junction box [Applause] now that that's through I got to put the cover on the body this part's really simple I'm just going to place the gasket on the cover like so and then I'm going to hold it up to where it belongs and screw it into place all right now that's covered and let's address the wire coming into the junction box I'm now going to fish this number two aluminum that's coming from the main panel in the house and to the top of this connector and down into the junction box I'm now going to tighten up the connector with this Phillips screwdriver all right now we got both wires into the junction box and ready to be connected I would now like to talk about how I'm going to splice together the wires as you can see here I got an insulated splice connector and right here is this tells you what wire it can handle from what range so as you can see it says it's from two to six on the cover here and also if you open up the inside of this cap you can see that is where the wire is going to go into and it already has the antioxidant paste inside so you don't have to worry about corrosion you can use this with the aluminum wire like I'm going to do here and you can also use it with copper and then on this side if you open this up this is where the Allen wrench goes to tighten it down in the terminal so this is to join together the wire coming in and the wire coming out so we're going to splice together that two out wire using these insulated connectors in order to connect these I want to bring the length of this so I can fold it into the box when I make the connection so I'm going to leave these cut about this high after it's flipped around now these are going to cut off to where they stop about right here I'm just going to strip this jacket by running my utility knife across this really light I'm now going to finish cutting this jacket off I'm going to unravel this paper and obviously the breaker is not on going to this wire it is kicked and already checked it to make sure there is no power going to this cable very important now I'm going to unravel the wire that's coming from the main panel here and again my goal here is be able to bend these up like so so I'm going to cut it off about right here in order to cut the wire I'm just going to use my alignments and just cut it off like so I'm now going to cut all these wires to length but this time as you can see once we fold these up and around we need to be able to connect them about the same length so I've got right here I'm not going to take my utility knife and just score about a half inch down around the end of this wire in order to expose the end on all the wires here then once it scored around I just gotta cut into the casing like so and then peel the casing off and that's how you strip the wires so again I'm going to do this to all the wires I'm now going to take my splice connector and start out with the grounds and hook these up first as my first Connection in order to do so I just got to pop the cap off the ends of the splice connector like so and it's going to expose the place for the Allen key to go and then at these other sides are the terminals in which we got to end the wire in this part's pretty simple all we got to do is Slide the wire right into the port then tighten it down and then first I'm going to back this out a little bit to make sure there's enough room inside of the connector now as you can see it lifted up the terminal in order to place the wire in so I'm just going to slide the wire right in here like so and again that antioxidant paste I'm going to make sure I get over the end of the wire you can see it on the end of that wire now just make sure it's coated well I'm just going to tighten that up and with the stranded wire it doesn't hurt to kind of tighten it wiggle it a little bit then tighten it a little more just to make sure we're on all the way and now again this is for the ground so now I'm going to take the ground and go into this side of the connector and then tighten that down I'm now going to tuck the ground up out of the way and place these plugs back into those ports to cover up those Allen holes now that's going to go on the neutral side we're going to tighten that up and now the neutral which is indicates the white wire by the way to this one that's indicated by the white wire to the neutral [Music] now cap that one back off and we're going to tuck that one up out of the way and now for the hots it doesn't matter if you put the hot here or hot here as long it's the one hot coming from the panel that's the sub panel to the main panel and then the other hot from the main panel to the sub panel as well like that should be just fine now I'm going to push all these wires snug back into the junction box like so now that all my connections are made I'm going to replace the cover with the weatherproof box and that's all there is to making the connections inside of my junction box I am going to take a piece of strapping to help secure the back of this wire to the back here as you can see that's going to help secure that wire a little bit better and now that's all there is to the work in the crawl space I'm now inside of my house right here is the main panel and this is the one I wired in the video from the past and I'm going to go ahead and kick off the main breaker first I'm not the type of person that Messes in panel box without the main breaker turned off I know some people do but I'm definitely not that guy I like to play it safe so I'm going to open this up and show you the 100 amp breaker foreign here's a screenshot from the previous video when I installed the main panel and if you haven't seen that I recommend you watch that there's a lot of useful information there and I'll put a link to it in the description below but if you take a look at these lug covers underneath of there even though the breakers turned off those lugs are still hot so be very careful when you ever you get into a panel box and again unless your experienced I don't recommend you even open a panel box but it's much safer because it's covering up those hot lugs here is the number two aluminum wire where it enters into the panel and as you can see I had to put a lug on here to accept the neutral wire and the ground wire is tied into the bar too these are put together in the main panel and then I have each hot wire going to this 100 amp breaker so now that I'm getting ready to have this in service I'm going to take out this 100 amp breaker and put the no locks on it I would like to mention here where the 100 amp breaker is placed and some jurisdictions because I'm use using number two aluminum would require me to use a 90 amp breaker here but where I'm at there is no regulation for that but always check your local building codes and always remember that electrical work is dangerous if not done correctly so be sure to check your local building codes and seek professional help if needed in order to pop this 100 amp breaker out I'm going to go ahead and just undo the lug on each side that's holding each wire so that's what it looks like out of the breaker box and that just hooks right into the back of the panel like so and now so now that you know what it looks like I'm going to go ahead and reinstall these aluminum wires back onto this 100 amp breaker and before I put it back on I'm going to put my Noah locks on so that way again it keeps it from oxidizing I'm now going to reinstall the wire into the breaker I'm going to tighten that down then I like to give it a little wiggle and then re-tighten it I'm not going to do the same with this wire I'm now going to tighten that down now that they're secured back onto the breaker I'm going to place the breaker back in where it came from I'm now going to take the neutral wire off and add the Noah locks as well and along with the neutral wire I had to do the same thing to the ground wire that's tied into this panel because anywhere there is an aluminum wire there has to be the no locks I now have all the aluminum wires covered with the no locks where it joins into the panel now I'm going to put the cover back on I'm now just going to kick the main breaker back on we're going to keep the sub panel breaker off for now I'm now going to show you how to wire a breaker into the sub panel and remember that everything from the sub panel to the main panel is already finished but we do have the breakers off going through this panel yet until we get this breaker installed I'm not going to turn it on then test it out so with that being said I must first run a circuit into this panel in order to wire up this breaker so let me show you how I'm going to do that per coat I got to staple the wires within 12 inches from this panel box so what I like to do is install a block right above the panel so that way it gives me a nice neat way of stapling the wires instead of going over to these studs so I'm going to place this in here first using construction screws foreign because I got several circuits going to be coming in through this stud space I'm going to go ahead and take a three quarter inch drill bit and drill several holes in through this plate because if you start running circuits and drilling the holes as you go you run the risk of hitting your drill into the wire so I recommend going ahead and running a bunch of holes across here before you start running circuits and you always drill right in the middle of the stud or plate because I'm going to be wiring a 20 amp circuit I'm going to be using 12-2 wire to power the receptacle for this circuit I'm now going to begin running my Circuit by running the 12-2 wire into one of the holes that we drilled and running it towards the outlet in which I want it placed [Music] here's my wire coming down from the ceiling and I know I want my outlet to be placed right here so here's a quick trick if you measure your Hammer it's usually about 16 inches long it's going to vary obviously for manufacturer but this is about 16 inches long so with that being said I'm going to drill my hole for my wire just about five inches above the hammer I can just eyeball it just through these few studs and then drill them out I'm now just going to fish the wire through those holes I'm now going to install this single gang electrical box this is going to be for the receptacle as you can see there's little tabs here on the edge of the receptacle and it's going to slide right up to the edge of the stud like so it's going to space it correctly for drywall I'm actually going to space it to where the top of the electrical box is right at the top of the hammer like so that's going to give me a good distance Here and Now what I'm going to do is take my hammer and Dust Drive the nails in the side to Anchor it to the stud and now I'm just going to take that 12 2 wire and punch through the back I typically use a pair of needle nose just to punch the back out real quick now I'm going to fish that wire right through the back of that box the code here is to have at least six inches sticking out past the face of the box for the wire so that looks like there's plenty there so I'm going to go ahead and staple that into place I'm going to secure the wire using these half inch staples and these half inch staples have a plastic piece here that's secured by these two nails and I like these just because the plastic isn't as hard on the wire as the metal ones and I can staple this within 12 inches from this box but I usually staple it a little closer than that as you can see and I'm going to hold the staple here and then just tack it on and always try to keep the wire in center of the stud and the reason why I keep that in center of the stud is that drywall screws can't hit it while the drywall is being installed and now I'm just going to strip this wire I'm just going to take my utility knife and then just slightly scrape over the sheathing and then I'm going to peel that off I'm then going to reach back in the box and cut the rest of the plastic like so I'm now going to take my wire strippers and I'm going to strip off about half inch to three quarter inch of the sheathing or insulation off the black and the white wire that's in this box I'm now just going to take my needle nose and just grab the end of the wires and twist them to give them a nice hook shape like so now I'm going to take a standard receptacle and start by placing the ground wire onto the Ground Terminal right here like so and then take my screwdriver and tighten it down first and you want to tighten down the screw in a sense to where it pulls the wire towards the receptacle like so now I'm going to place the white wire which is the neutral on the silver terminal and tighten that down and then the black wire goes to the gold screw terminal and then the button up this I like to put these screws if they're not in use all the way down into the outlet for now I'm not going to fold my wires back into the box nice and neat and then push the receptacle back into the box and then screw the screws that are on the outlet into the box now I'd really like to stress that I'm putting this on here now before the drywall just so I can temporarily have power out here so now that that's in I'm going to put the cover over this and same thing this one go on obviously until you had drywall but for temporary it's a necessary thing now I'm going to staple the wires on the way back to the panel box when it comes to stapling the wires I typically staple them every four foot or so so that way it holds it going up studs and whatnot and I always nail it down in a corner right before it turns up going into a Direction thank you once I get to the end of The Wire that's going to come down through the sub panel I must first knock one of the half inch knockout outs and install a Romex connector I'm now going to take my linemans and just pull that knockout out I'm now going to take a 3 8 rmx connector with the snap lock feature in this case you don't have to use a snap block feature but I like it because it's simple to do and I'm just going to put my needle nose down through the top of it and then push it down through where that half inch knockout came out and spin it to where the screws are facing out like so and then we're going to rock it right into place I'm now going to cut the wire to length typically if you cut this off about six inches or so below the panel you're going to have plenty by the time you go to wire this in here so I'm just going to grab about six inches below the panel then just snip the wire right there I'm now going to Simply fish this down into that Romex connector I'm now going to secure the wire to this block that's coming down from the wall and then to the board that we put in here earlier I'm simply now going to take my screwdriver and tighten up the screws on the rear Max connector now that we're secured to the Romex connector I'm now simply going to take my utility knife and Go Lightly over the jacket of the wire and then strip this yellow sheathing off and also remove all this paper that's inside of the wire as well all right now I've got the jacket off the wire and now I'm going to place my breaker in here to know how short I need to cut these wires the breaker that I'm going to be installing is a combination breaker meaning it's arc fault and GFI so the circuit will be protected with both and if you look on the back it's plug on neutral meaning this bar or this bracket will plug onto this neutral bar so we're simply going to slide this into place by placing it directly into the slot that's here and then slide it into the neutral bar just like so goes in real easy so now we know we can just bend the wires over and that's where we're going to land right into this side of the breaker so if we cut off about right here we should be totally fine and I'm just going to cut the wires using my alignments and now as far as the copper wire goes remember we got to separate our grounds and our neutrals here so we cannot cut it that short because we got to land it into this Ground Bar so we're going to hold this down here in order to go into the ground bar so if I cut it anywhere in here we should be fine about right here I'm now just going to take my wire strippers and strip these wires just like we did for the outlet I'm now going to pop the breaker out and we're going to place the white wire into the neutral terminal and then the black wire is going to go into this gold screw that's in the back of the breaker and you can see the gold is right there in that terminal I'm going to back out the neutral screw on the terminal and then we're going to slide the neutral wire down into that terminal after it's in we just tighten it up and I'm now going to do the same with the black wire going to the gold terminal now I'm going to tighten that up now that the wires are installed onto the breaker I'm just going to snap the breaker back into the slot that we cut it to fit to and I'm now going to land this ground into this ground bar so I'm just going to take it and kind of bend it over a little bit and we'll just place it in any one of these are fun all right that looks good now let's install the cover here is this panel box cover and now if we open it up as you can see we got our screws to secure it to the sub panel and now we need to knock out this area here because that is where the 100 amp breaker is at the top of this panel and as you can see it already has two slots missing here so this number one is where we just installed that breaker and then our next breaker will be installed in two then we're going to go back and forth down the line so now I'm going to punch this out all right let's go install this panel in order to install this cover it simply sits over the breakers and then we're going to place the screws in from the outside of this cover into the holes that you see on the outside of the panel but this would typically be something that is installed after the drywall but I always put this on temporarily even though the power is not going to be officially on here for a little while but while we're using it temporarily it's important to keep People Protected from running into the sub panel so I'm going to go ahead and place this over the breakers like so and you can see that fits on nicely and now what I need to do is just line up the holes with the holes that are on the panel and put a screw into place to hold it I'm going to finish setting the screws with my impact because as you can see there's a lot of screws to place in here see there's a spot here that needs filled in with a blank if I didn't have more Breakers going in here but I don't need to put a blank here because I'm going to have plenty of Breakers going in here now let's kick the main breaker on in the house and then I'll kick this breaker on and see if it Powers my receptacle I'm now here at my main panel I'm going to open it up and kick my 100 amp breaker on now we should have juice flowing to the outside all right I'm back here at the sub panel after turning on the main breaker so now I'm going to open this up and kick the main breaker on this panel and it is now live and we should have juice flowing to this so now I'm going to kick this breaker often on so now we should have power over that receptacle that we just installed there are two ways to see if I have power going to this receptacle the first one that you could do which is use your non-contact voltage tester and then just touch the wire that we just installed it's beeping so we know that there's current flowing through that wire but for the people that don't own one of these you can just simply clearly just plug in anything that requires power and this is going to be my router in this case so we're going to plug this in and see if it turns on all right sounds like we got power so that was a successful install if you would like to see I'm going to finish wiring this garage into this sub panel or if you want to see how I wired my main panel check out this video or check out this video it'll help you out foreign [Applause] [Music]
