 Welcome to the network engineering video blog. I am your host Michael Crane in this lengthy follow-up to video number 82 Making an isolated ground Cyberpower PDU we go full Monty by stripping the old AC receptacles out of our cyberpower PDU and replacing them with the Levington 5362-ig Isolated ground receptacles, okay? The problem is the footprints of the new receptacles are not the same as the old receptacles So we have to do some customizing to our new Levington Levington receptacles But we've got to make it work, right? So let's get started. Okay, so we're gonna start converting this thing. So excuse the reach and I grab my screw gun here and Kind of speed things up a little bit And I'm just gonna start with the case screws. All right Pull the cover off this guy. Okay Since we're gonna go ahead and replace this crowned wire. I'm just gonna go ahead and and clip it off. Okay? Okay, excuse the reach Clip this guy off Now I'm gonna save the nut and the shake-proof washer in case one of these days. I want to convert it back All right I'll move that off to the side Okay And we've got another one Down in there. I don't know if you guys can see it. Let me see if I can zoom in Yeah, there we go. Yeah, that's right down there Now this one's a little harder to get the Get the wrench in there so I had to go ahead and clip them off because I am going not gonna use that that I that I Connector okay And now I'm gonna go ahead and pull the receptacles out. So I'm gonna go ahead and just oops Remove the screws now When I did this originally I was trying to figure out the puzzle of How to get this guy out or Or should I try to pull in this one out before pulling these out or try and pull these out before pulling this out and I I played around with it for I don't know 20 minutes And I finally Determined that I can't get either one of them out The way it is and I'm not exactly sure how they manufactured this but my guess is That it was spread apart a little bit when they assembled it So that's what I'm going to do Now to keep from scratching the enclosure I'm gonna Go ahead and wrap a little tape around it. That should be enough now. I'm gonna very gently Get in there And it doesn't really matter if I put it on the connector or not or the receptacle But I do want the bottom of the jaw as close as possible To this corner right here because otherwise I'll put a crease in the middle And we won't be able to straighten that out. So I'm gonna Get in there the best I can Gently Pull it out just a tad I'm just gonna go down. I'm just doing it a little bit as you can see That's going along here All right, a little bit more right here You don't want to do it too much because we got to push it get it back into place All right, that looks pretty good. Yeah, you can see I kind of Hey, I got too high up on this kind of den of it Well, hopefully we won't see that when we're done Yeah, you just have to be real careful when doing this Okay, so let's go ahead and see if we can get these guys out Yeah, you want to keep these so don't throw those out or damage them We are gonna reuse them. They're getting there there So let's keep all these guys and if you're wondering what these are these go over the The screw connectors Also covers this little tab right here, which this is electrically active. I'm I'm surprised it. It's even up there like that But yeah, it's they definitely wanted to cover that up because it's getting real close to the enclosure as you'll see when we go to install the isolated ground receptacles Now I'm not going to do a full tear down, but I will take a picture of this and we'll see if we can I identify some of this but Oh, and I'm on the other side of that see these jumpers right here. They've got a jumper Trimper right there and a jumper right there. You see these jumpers right here. Well, if you flip this guy over Those actually go up into this receptacle right here and are mounted To this receptacle yeah, check this out. This is this is kind of clever I guess When I was first taking this apart I couldn't figure out how What how that receptacle was tied to that board and vice versa See Look at that Yeah, that's that's pretty clever Let's zoom back out here Okay So let's go ahead and finish just assembling this guy So I I know because I've already done one of these and I'm not going to reuse this ground wire right here So I am going to Clip that out and we'll go ahead and remove this is This is these are all just tied in series right here. This is the output from the search protector Okay, they've got these things jammed in there. So this is actually stranded wire that they've soldered and Literally shoved in these holes But I mean it's okay, it's it's probably not the the cleanest looking job, but I guess it's okay Okay, so we've got Let's try it here. I Shouldn't be using these little cutters for That I should be using my my linemen's pliers All right, you don't want to cut this one too short right here. We're gonna reuse that wire but this this ground right here this whole set of ground wires with these With these connectors on there. We're not gonna reuse Now because of space inside there and you'll see later But they look all pretty good. This one is barely hanging on there, but it's okay. They've got all shrink wrapped. It's all very nice This looks all nice and neat So when we are gonna reuse these wires, so I'm gonna keep those Let's see. What else we got here folks. Okay, let's go ahead and now we can Get to this guy pretty easy I'll take him out. So let's see here We need to I guess we'll go ahead and pull this ground off real quick We can just throw this guy away. We're not gonna reuse it in this video All right, so now What we've got to do is I'm gonna start moving the wires from here From the old receptacles to the new receptacles But first we've got to do some modifications to the new receptacles Okay So, let's see if I can zoom in here. So that's the The old receptacle that this one came out of the other box or the other PDU. I mean Here's the new receptacle and And there's a few differences and I looked and looked I probably spent an hour on the internet Trying to find an isolated ground receptacle like this Or an isolated ground receptacle in this form factor and I could not find it so These are pretty close right here. These are Levington, I believe just to remind you an isolated ground. So this ground right here is Not connected in any way to this mount This mount or this mount Now these mounts are tied together and that's very easy to see on the back So here's the little tabs for for the middle mount and of course, it's just one piece of metal that's been Bent over like that. That's a better view. So Neither this ground or this ground is tied to any of these Now with this guy right here, you can clearly see there's a ground screw It's just one piece of metal right there. There's the the mount for the middle right there You can see it's just a block pressed in there. It looks like and and these two right here. These brass Brivets it looks like are tied to The ground so these two grounds and these are are all tied together, right? So we need to make This guy more like this guy. So we're gonna have to remove these these mounting tabs we don't need them anyway because it mounts in the middle and You can see That Let's see if I can get a good shot of this. Well, you might not be able to see it on camera the ISG Receptical has these like protectors right here. This is to you know, protect the screws from hitting the side of the case, right? So if you have a metal box it protects it But I learned when I was doing the first one that these are too big So we need to cut them down a little bit and I've got an example right here Of one that fits and the E is for example So what we need to do And I hopefully you can see this is we need to shave these guys down, right? And we need to remove the mounting tabs right here on both sides And we also in this example doesn't have it. We also need to remove This little this little brass plate right there Okay, and we need to do that. So when we put the wire Around the screw Just like they used to do in the olden days But when we tighten it down, we want it. We don't want it poking out beyond this No protection ridges. I really don't know what to call them Okay, that makes sense. All right, so I'm gonna I'm gonna take the Camera out into our workshop and we're gonna modify some of these. All right Okay, so we're out in the Fuck off the workshop aka the garage And okay, let's start Start getting these things fixed up. Tell me first thing we need to do is remove the screw And it's got keepers on these screws. That's why they don't fall out didn't know why So I'm just gonna push them through So I can get a grip on them and make them out. All right And I might as well do them all while I'm thinking about it And of course we have the example which is already done. Okay Okay So the next thing we want to do is we're gonna Cut the tabs off and I'm gonna use my A little dremel tool right here and this is kind of a little metal cutting blade It feels like it's made out of some kind of stone All right, I'm right-handed. So let me see if I can set this up and And do this so everyone can see Okay So I'm not actually cutting all the way through Let's see if I can I'm just I don't know if you can see it on camera I'm just scoring it. Okay Just enough so when I Yeah, see it's not Snapping right. I want it. So when I first bend it down it should start breaking So I didn't score it enough. So we need to score it just a little bit more. Okay. Here. Let's try this again All right There we go Yeah, see that felt rarely at least soft Don't try to break these off without scoring it first Because these things are are used to hold this receptacle together and you'll bend it all up and Yeah, it's it's not pretty. All right And we're gonna come back and blow all the dust off these As soon as we're done. All right excellent So now what I'm gonna what I'm going to do is I'm gonna remove this This cutting blade and I'm gonna put this sand disc on there For lack of a better term I and that's for the uh The plastic keepouts let's just call them a keepout that makes sense Okay, so I've changed bits out and what I'm going to do is very carefully Just take this and and grind these keepouts down to the same sizes As the example I showed you earlier. All right. All right. So let's go Okay, so now I'm just going to take my knife and and debur the The edges on these Keepouts, okay And after I clean them Loose strands off get them all cleaned up. I'm just going to take some candor here and blow them all out There you go. All right. Okay So we've got the The new levitan Isolated ground plugs all modified Well, almost all modified And ready for installation. We need to take these little I don't know what these are called. It's so you can put two two wires in there But it's it's adding too much height to our screw right here and uh, we we're As you can see, we're we're really struggling for height And that's what's nice and bad about this PDU A lot of PDUs these 1u PDUs will only have like single plugs right here And it's because it's hard to squeeze something like this And this small of a form factor as you can tell it's You know the plug itself is using that pretty much 1u. Anyway, let's go ahead and remove all these So anyway, that's what I'm gonna do. I'm not I'm gonna stop I'll do this off-camera. No one's really interested in seeing me do this And I'll be back All righty, so I've got them all removed. I can just go on the trash or the recycle bin All right so now We are ready to start Moving the wires and basically what I'm going to do as I'm just going to Take them apart one at a time And then just start assembling these Just exactly the way these are set up I will need to modify the wire a little bit. So Let's get started Okay, so I readjusted the the camera a little bit I noticed when I was reviewing Some of the video my hand was getting in the way of the lens and was actually focusing on my hand and Not on what I'm doing Since we don't have those those little keepers or whatever they're called To hold these wires Like so I'm going to have to bend loops in them. All right And I'll try to do this on camera where everyone can see So first I'm going to straighten it up a little bit And I need a little bit more Wires for the our loops This is 12 gauge wire I can get that off there. There we go My 12 gauge just does not on these Strippers just doesn't seem to work too good It's probably worn out There you go. Okay, so that should be enough So we want our Our receptacles like this And we want the wire so when we tighten them up Righty tighty lefty loosey We want the wire to wrap around this way. So I need to bend my My loops I guess to the left. Okay Let's see if I can show you how to do this. Okay And I know they're not complete loops but As you'll see, it's it's kind of hard to get these In there especially Uh If there's already wires connected So we just need to use these partials I can get down in there But you can see I it's got a pretty good bite on the wire. It's it's got most of it under there I mean, I've seen people do almost complete loops with them, which would be That would be okay. I guess I could pull these screws out and try to Do something like you know screw it back in but I don't think it's I don't think it's I think this is a good enough bite for What we're doing I mean, it's definitely more of a bite If you think about it, it's definitely more of a bite going from here looped around here than it is just going straight down Like it would be underneath that metal that metal tab, right or that metal keep so make sure they're nice and tight Okay And I'm just gonna now I'm gonna do the Other side. I don't know how to do this where you can see Oops So I'm just gonna put just a tip of my linemen's pliers and just Turn it like that and then Let's see is this work better and turn it like that And you can use your linemen's pliers to kind of straighten them up a little bit And you can make the loop a little bit smaller if you need to I think those will be that'll be okay And we just oops Got to put it on there the right direction Okay And we'll put this one on Let's see you might need to uh Need some adjustment on these guys To get it down in there It'd be easier if it was sitting right in front of me That's why I'm I'm struggling to do this because I'm trying not to cover the camera up at the same time I'm uh trying to put it together This one's gonna need a little help so you can see I got it I got it down in there. It's not tight yet Make sure all the adjustments are okay. You definitely don't want the insulation underneath the screw All right, and you also don't want it pulled too far back either because Then it could accidentally Touch on something else, but I think we're good there. So I'm gonna tighten them up There we go All right now for the next ones. Okay, so now that that's done Let's get our ground on there This is this is going to be a little bit different than In the common and the um or the neutral and the the line voltage wires because There's only one screw and it only really holds there's only originally designed to hold one wire But we've got to make it hold two wires So I I'm going to get some number 12 Ground wire. I don't know if you can read that. Anyway, it's solid core 12 gauge and I'm just going to I'm going to cut a little bit extra right here And I'm going to bend it up now, so what I'm going to do on this one is Since it's only as one it's got a It's got a hole right here I don't know if you can see that. Anyway, it's got a hole right there the slide of wire up underneath there Okay, so you can stick the wire off in there and and this tightens up on it But we also want to use the top side Now so for the first one I guess I should say the last one if they're sitting in there like this Then this is to me. This is the last one. This is the first one so This one we can we can go just straight In a hole the hole But these others I'm going to have to put two wires on right and what I learned is it's easier to put The looped wire in the top And then put the straight wire in the bottom. So in other words, it's going to go loop straight loop It's going to go this is going to be straight straight Then loop straight um Yeah, loop to straight and loop to straight and loop Straight and you'll see what I'm talking about when we start doing this So, okay, that's First off, let's go ahead and This is going to be the simple one straight to straight So it's going to go in there like that now we need to come down to about right there Bend it up And if you notice I'm cutting it a little bit longer before I strip it And I do this and yeah, I'm going to have some scrap, but it really if you try Cutting and doing all this stuff without any waste You're going to have a lots of waste because you're going to mess up here. It's not going to be bent, right? You need to trim a little more and um It's just Believe me it it can be a hassle All right, so this one is Odd man out because it's just straight to Yeah, see I even made this one too long. Look at that And let's trim this guy down about right there looks good Well, let's see. Oh, should I make it too short? That's okay Wow See what I mean It's um So you definitely want to give yourself Some some extra there we go. That looks pretty good, right? You don't want the plastic up underneath the conductor There we go. Okay Now this one I can tighten up as he is done And you can put a good amount of torque on these things and and you want to because You know, you don't want your your Um conductor is falling off Okay, so this one we need a loop and a straight So I'm going to do is I'm just going to Got some wire Plenty of wire Okay This one's going to be a loop So I'm just going to Give myself a little bit of extra there Let's drip it off and want a little bit of A little bit of plastic right there All right, that's probably a little too long for a loop about right Yeah about right there. Okay All right Maybe tighten it up a little bit Now we got to get it underneath This guy and this is Not as easy as it sounds Whoops. Okay. Yeah, so see how it fell out Now the way this thing works is As this got a little plate on the bottom that that when you tighten the screws up it sucks up against This brass conductor right there well when it's When you pull the screw out You can't just stick this on there and put the screw in there because The screw is not long enough with the wire under it to To reach that metal plate. So you got to hold it upside down Ain't you need at least a couple threads In this ground screw to Now hold it in place Okay, you know like that. So now We've got a couple threads in there. I just need it to hold it in place long enough to So I can get this conductor in there Let's see. I got too many threads in there Here let me I need to tighten this loop up a little bit. Oh, no. Is it coming out? Yeah, this this is not the easy It's not easy Come on You can get in there. Come on That they can go in there very smooth That looks okay all right So I got to get everything back in place here Now we need another bend See if I can get this right this time Right there It looks a little bit long We'll try it. This one's gonna go down right right there Okay Straighten all this stuff out. Okay Yeah, I could have shortened this up a little bit. Maybe I should And the reason why you want to shorten it up is especially when you're going by this thing right here this um The protection circuitry Is you don't want a bunch of wires You know pushing against all this stuff. So I'm gonna go ahead and Trim him a little bit more Shorten this wire up Okay There we go That's better Okay, so we're gonna go over and under And I am not going to tighten this guy up because we need to put another one of these in there So the last thing you want to do Before you stick this back in there is You need three leader wires These are simple enough You just uh, well, let's start with a green That's the hardest to do for sure One one went on there Surprisingly easy Oops Oh, I stand corrected Yeah, this this is tight Squeeze for this thing But the good news is we're getting plenty of threads on it. So I'm not worried that it's going to fall off Or it doesn't have a good connection It's just not Easy to put together All right, so I'm just going to run it straight out that way Straight to the left. All right, and let's see unless we'll do the white Since we've or the common or neutral whatever you want to call it next Oh, that looks kind of long Let's trim that guy down a little bit. There we go Tighten them up. Oh, that's much easier Okay, run them out to the left And we'll do the the line side. There we go Tighten them up And I'm not going to install it right now just be in the way while we're working but It's ready to be installed. All right So the next thing we're going to do is we're going to work on Our last receptacle here So I guess we'll go ahead and get this guy mounted on next This this thing right here needs to be The isolated ground plug is A little bit wider And you know just the outside part than the Than the non one or the original one and as you can see the the hole spacing right here is a little bit Wider these are closer together than these are going to be I could get a ruler, but believe me I've already I've already done this So what I'm going to do is very carefully Bend these They need to go they need to spread out just a little bit and they also need to go Out this way I don't want to say a lot but with a But quite a bit and Unfortunately, we can't leave them angled like this So this is where it gets a little bit a little bit tricky. So what I'm going to do Is I want to put An L bend of some some kind in this and I don't know how to explain it. So I'll just show it to you So I want the bottom part to go out at a 45 and then I want the top to go Because we want it to go be perpendicular to the board to on out and up Yeah, something like that and You want it to be as close to the To the PCB as possible. So when this when we put our new connector on there It mounts flat and doesn't push out too much All right, let's see what that looks like kind of straighten them out a little bit Can you kind of see the see out the angle Going out and up. All right Yeah, let's see. How does this guy mount on there? We want Let's see it mounts like this so the Neutrals at the top the neutral or this side right here so We want it like Mounted like this and I'm going to slide these guys There we go. So I got the neutral side in Oh Didn't quite get all the There we go Yeah, see how it's pushing away from the PCB. So very carefully I'm going to Push down on this because we want to hold it As close to the PCB as possible And then tighten these guys up. Okay, there you go Okay, let's go ahead and strip this while I'm thinking about it Because we're gonna need to tighten that All right, very good strip him while We're stripping stuff There we go I do believe we're ready to assemble Okay, so before we assemble I need to um We need to put these guys back on there and The way the easiest way I found to do it is And and what these are these little plastic pieces I don't know what kind of plastic it is. It feels very durable and it's probably Made that way on purpose You know if any sharp pieces won't go through it, right and it's so won't so the uh the mains Uh power lines won't touch the enclosure Oh, I did see something we forgot I need to put in a leader for this ground right here. Okay So let me go get some wire All righty, make sure that's unscrewed Make sure you don't have any insulation under the conductor Tighten them up nicely There we go. Okay Where were we? Oh, yeah, we were um Putting these plastic Uh, I don't know what to call them conductor protection Pieces And uh, like I said, what I do is I I hold them on with a screw And then I put electrical tape to hold them in place because obviously you can't leave the screw And there when you're assembling it, okay And I just take some electrical tape About you much. I just kind of put it on there like that make sure that's in the right spot And Just tape it like that And I know there's there's probably a lot of people out there That do not like electrical tape. It does get a little bit gooey if it gets hot and old It does work I mean, I thought about I could get I could probably go buy some really big Uh heat shrink, you know and cut out You know donut pieces to put on this but I think this will work just fine And we won't have any problems And that also gives me a little bit extra added protection Okay, so now if that's held in place with the electrical tape, we can remove our screw All right And now I I'm pretty comfortable kind of moving this thing around Inside there and it's really I could have probably held this in with my fingers putting this one on But one of the things I noticed when I was doing the other one is is making sure this bottom one didn't slip out So electrical tape, I know will hold everything in place Long enough for me to Get this back together Okay, and I think we're actually ready to put this We can go ahead and just mount this guy right up. I think we are ready So I'll slide them Just want to slide them Oh, there we go. There we go Excellent, okay I'm ready to put these this guy in, huh? I get this wire up. This is our ground for PCB This is our ground for a receptacle All right. Now we need to put those These plastic pieces on all our Receptacles here. So I'm gonna kind of get started doing this And I'll show you a cup. I'll probably turn off the video This isn't this isn't rocket science and it's not very interesting and someone actually might know of a better way to to do this than this multi-step process of putting the screws on and that sort of thing So what I'm gonna do is I'm gonna go ahead and put all the plastic on these I'll be back Okay, so now that I have all the plastic pieces Held on there were some the screws and I go ahead and I put the electrical tape on and I just Push it down like that and Like that. I don't know if you can see that Like I said, the goal is just to hold it in place for assembly And adds a little extra protection, I guess Maybe you want to make sure that the the plastic covers the The mount the the conductor mounting screws Okay, so that's I'm gonna do that with all the rest of them and I'll I'll be back Okay, I have all the tape pulled in the plastic protectors on go ahead and remove these These mounting screws real quick So now I I do believe We are good to go. I've been these up a little bit. We've got to Probably put it over these. I don't remember how I did my last one, but I think I went over the the power input wires So, yeah, let's go ahead and Pop this baby in there carefully Yeah, I'll just have to work with this There we get it I want Okay Snug them up a little bit Okay, and if we thinking it's that it's that these plugs here You know, they're hitting the enclosure and that's what's making it hard to put in it's it's not really it's it's the the stiff 12 gauge wire Holding these things they kind of if you don't get them exactly lined up you got to kind of push them around and And if you've ever worked with 12 gauge wire, you know, that stuff doesn't bend easily and we've got three We've got the ground the neutral and the And the line Wires all on there. So you got three wires per Receptical. All right. Well, I've got those in there Okay Yeah, I'll look pretty good You can see you can see we have plenty of clearance underneath there All right bend this back and Place a little bit Okay, yeah, let's start uh, that's time just to connect all the wires now Now there's a couple ways to do this. I'm going to make it to where it's I can Take this thing apart and service it And uh, so I'm not going to use like crimp on connectors. I'm going to use wire nuts. Okay So here's the wire nuts I have And uh, I'm going to use the yellow ones. It says the yellow ones are for 14 or 22 through 14 But I have they work just fine on the 12 I could even go up to the red ones but uh We don't We don't need to go that big it'll work just fine and this this wiring that the goal is is Both the wires need to be in that little spring area So you want to make sure the wire is Is nice and clean no straggly edges off of it You just put it on there make sure they're they're even both wires Or all the wires that you're using if you're doing more than two Um, make sure that even I don't push it down on there And you just screw it on and you really have to put Some effort into these guys I mean not enough to break the wires, but you want them really tight and these things will not come off They're used in home wiring all the time As a added safety precaution I am going to Put some electrical tape around them Just in case One of them decides to shake loose Which it probably won't I'm sure all the people that hate hate electrical tape are just screaming at me There's a lot of people that don't like electrical tape All right, okay, so we'll go ahead and Push them down in there like that. All right, he's all tucked away Okay I'll go ahead and do the Neutral Or common And you notice I give myself a lot of slack in here instead of making it real Tight and short I do that so I can easily move them around and and work on it And sometimes you can't do that if you're in an electrical box. It gets uh It gets too crowded But uh, we've got plenty of real estate in this In this enclosure All right, oops. They aligned everything up Wearing it on there I'm nice and tight and we'll just tuck them away down there Okay, very good Okay Here's one of those crimp on connectors. I was telling you about these these are kind of the same way they've got metal inside there You stick the wires up in there and crimp it on the problem is is You can't really uncrimp it. You just have to cut it off and If I want to come back and service this later, all I have to do is take the electrical tape off and unscrew the wire nuts, right? Okay, so now we need the ground Okay, we got that one And we need one to go To the other side over here. Oh, I made that wire a little bit short Hmm. I'm gonna go get a little longer piece of wire all right stranded wire man this stuff will Poke you like a needle Okay, so see how I got them all All lined up even This time I'm going to use a red one You can see it's a little bigger to get all three of those wires in there. I'm just going to put it on there and Tighten her up and you can pull on the individual ones Make sure that nothing's going to come out usually won't If you if you install it properly, you won't ever have any problems The only time that I really have any problems with wire nuts is is when I'm if I'm putting a really small 22 gauge tied to like a a 12 gauge wire as uh, you can kind of Over torque the small wire and you'll end up breaking it But we don't have that problem here and it'll just Run him through here like this I'm nice and tucked in there. I'm just doing this last ground right here Get on all these Be the exact same length Sorry, hopefully you guys can I'm not sticking my big paws in the In the way of the camera there all right This one's a little tighter to get to That hopefully we get it on there. Okay There we go Get them taped up. Yeah another scratch on there All right. Well, sorry to interrupt But I had another wireless microphone Uh meltdown if you watched my previous video Uh the same thing happened Um, I think last time it was uh a cable Was flaky and this time the battery died so I'm gonna try to do a voiceover of what's going on here if I can remember So I'm just talking about the um the receptacles right now and we just finished wiring it up So one of the things I wanted to point out Oh, let's see here Is Oh, yeah, so these these metal Brackets on the back of these receptacles Are normally tied to the the mounting ears or tabs on the receptacle and and and's grounded but there's a The screw right here actually ties to that back tab and that's what I'm saying and so That little metal tab back there is actually going to be grounded Uh to the chassis Uh or the enclosure. So that that's okay. So this is going to be protected Even if a wire jumps off and you know power wire and hits that guy and So that'll be protected as well. I just wanted to bring that up So uh and now I'm gonna do some testing Of the unit. Okay, so we're gonna redo some of the testing On this uh This pdu and there's a couple reasons why the first reason is is the audio died With my remote mic in the middle of right when I started testing actually It was in the middle of the video right when I first started testing So I wanted to go through that again plus I wanted to take a little more time and and look at what we got so First things first. I've got the the fluke set on ohms We're going to test for shorts. Okay, so zero point two is a direct short All right. So first thing we're going to test is between the ground pin And the ground on the receptacles. Okay That'll be 0.4 0.3. All right There there we go, right okay And I'm just going to go ahead and check them all real quick Okay Okay, all the grounds are good Now we're going to this is the common or the neutral really in in our case So let's go ahead and test the neutrals Okay, now we're going to check our power pin All right Oh gotta be turned on All right And I did forget to check the front one So go ahead and test him real quick Let's see we're on power I guess I should call it The line voltage. Okay And here's a neutral Okay, so we know the connectivity Of the new wiring when we put in this is good Okay, so now we're going to check for shorts And the first thing I'm going to do is I'm going to put on the ground pin And I'm going to check The the line and then the the neutral. Okay So on the ground pin Says one meg. Okay Yep Yep Okay Okay So we don't have any shorts between the ground The ground and any of the lines Now we'll just check Between the power line and the common Okay Oh, that's power. Yep Okay, that's that's about right. You have to remember it's going through that circuitry That's inside there 477k Okay, and We turn it off Yep, we we're dead. Okay Excellent very good Okay, so now we're going to test between the ground pin On the plug which this is isolated ground, right? And the on the case ground, right? Okay Nothing And what's making it jump up is if I put my hand on it We're getting we're getting connectivity Between between me touching the case And so I have my finger on On this guy right here if I put a I could put a clip on it and then I could It probably there we go. So now I can Touch it and move around without having to worry about it But I don't see Yeah Oh, that's the ground inside there. Okay And uh, yeah, I'm just touching around Okay, so we have no connectivity between the ground pin And the case okay, so I know that Electrically, this is good, right? There's no shorts Between any of the pins and the enclosure So it's it's safe to to handle right and and it's on I believe it's on nope. It's off now It's on Okay, and we've got our our power our ground and our surge light up And we're going to go ahead and let's let's check some voltages. Okay, make sure This thing is working. Okay So first between The line and the neutral Okay 125 volts AC. I hope you guys can see this. Okay I'm not going to go through and check all the other ones. We know the connectivity is There we go We know we just we just check that the connectivity between all the plugs. We know they're all good So I'm not going to go back and check the voltages and all of them. We Well, yeah, let's go ahead just so everyone is Is assured this is going to be okay. Okay So now what I'm going to do is I'm going to check between the the enclosure and the line side the enclosure and the The neutral and the ground and the enclosure. Okay And I'm going to go ahead and just Clip my negative lead on there Okay, so first off between the enclosure and the line side Getting about 110 volts All right So that's uh, let's see. What is it to the ground here or to the neutral? Okay, so we've got about 125 volts from the line to the common Yep into the isolated ground and so this thing is acting like a I mean Obviously, we're not getting 110 volts across the into the case So the line side is swinging up. All right to 125 volts And the case is floating. All right, so it's It's it's like measuring half a capacitor. So it's it's like an open-ended capacitor And I don't know. Maybe sitting on this bench Yeah Yeah sitting on the bench actually made a difference right a little drop down and um And uh, but what we're really interested in so anyway, that doesn't really mean A whole lot because we've got in the line side, but what's really interesting is What how much and and that's this is all a capacitive coupling effect What happened is is is the electronics in this This pdu Or you know get are pretty close to the enclosure It's not really shielded inside there And so as that as the ac the mains voltage swings It's going to transfer some of that swing to The enclosure right and that's uh called capacitive coupling So the real interesting one is going to is going to be how much Voltage is going from the enclosure To the the ground right And I just so happened to have a A ground right here. This is uh, this is a actual pigtail coming out of the the wall socket Right here. So it's plugged in right here. I'm just this is the ground Wire right here. This actually is a molex connector that goes to the barbecue controller And I'm working on another video on our open iot channel But yeah, so we want to see okay. We're getting some capacitive coupling. All right, how much voltage is going to be transferring between the case and the Equipment ground right and so we'll just go ahead and Measure that real quick and it looks like about Uh 1.36 volts 1.4 volts something like that That's not a lot, but Let's see let me lift it up Well, there we go now we're about Now we're about 10 volts right and if I could so the static mat is actually Dampening it. It looks like a little bit and if I could get it up on something Let's see here There we go Now the now we got about 16 volts of Capacitive coupling as coming from the case Going to the equipment ground. All right So that's that's pretty interesting it there should be hardly zero Look I can I can change it just by by touching it Um, there should be zero current or very very little current going through it, which we will We'll probably measure In a uh in a future video. Okay But this this looks okay. I'm I'm not too worried about that All right All right, I'm gonna put the lid on this guy. All right well So I've had my remote mic batteries. I don't only die in the transmitter, but also in the receiver I don't know how much audio you heard. I might have to do some voiceover When I edit this because It died and I stopped and it stopped recording me. Anyway, so I'm still putting the screws in Excuse the reach Okay. All right. So now That kind of gives us an idea of how much I need to bring these This back panel back in You can see it kind of This side's almost all the way back and And then it kind of goes out. So what I'm gonna do Since this one is closed. I'm gonna go ahead and put his screw in there That'll help with With the lining of the other ones Back that off a little bit. All right. So now we got to get this guy in and This guy here Okay So I did is I just got a little bit of a clamp and I'm making sure not to Put the clamp on the receptacles. I don't want to break them And I just have it kind of clipped to the Both sides to get so I can get these holes aligned, right? Oh, yeah, that looks That looks pretty good, huh? Let me go get that other one That looks those look very nice. Don't they looks just like you bought them in a store I'm gonna put a label on there So I I know that these are isolated ground receptacles and that the enclosure will need to be Racked to have proper grounding So everything the surge light is confusing but When the uh when the led is on That means it's protecting against surge It's got a good ground And it's got power.
