hi this is bill for Sparky channel calm minutes house renovation time to come on in let's fixture up today I'm going to be replacing a circuit of old two-prong ungrounded receptacles this video is for educational purposes only and only competent persons should attempt this installation and the first thing I've done here is I've plugged in my ideal transmitter you see I actually have an adapter on it this one comes with three prongs but if you just put a little adapter on it and plug it in it'll give you the correct reading this reading means open ground right here that's what this means open ground which you would expect because this is an old two-prong ungrounded receptacle so you plug that in it says open ground and so the next thing I'm going to do is I'm going to use my ideal circuit breaker finder receiver you see this is the transmitter which also doubles as a really good receptacle tester and this is this is the receiver right here now I'm going to go to the main panel with the receiver and I'm going to find out what circuit this is on but not only that I'm gonna find out the whole circuit I'm gonna walk around and plug this in to all the various receptacles and I'm going to find out the whole circuit that this is on I'm gonna work on one circuit at a time alright so this is the receiver I'm at the main panel just take a turn it on and it chirps and the green light and the red light are on now go over all the breakers for relative strength do a good job of it okay that indicates for the tester all the relative strengths okay here's the receptacle I'm excuse me here's the breaker right here and push that turn off here we are back at the receptacle notice all the lights are off they have a piece of blue tape above this receptacle and that's going to I'm going to put a piece of blue tape for every receptacle as I find that as off right now and that'll mark all the receptacles on this particular circuit here's another receptacle in the same bedroom I'll plug it in and this so this is one of them so this is a second receptacle on the circuit and don't be fooled because it has a three prong receptacle that doesn't mean that it's grounded I don't think it's grounded - someone threw on a three prong receptacle at some point here's the third receptacle in the same bedroom and it is off as well so this is part of the circuit now I'm in an adjoining bedroom and I found another receptacle that is off so I have marked it above the acceptable with some blue tape here's another receptacle in the adjoining bedroom which is off and I have marked it with blue tape as well and here's another receptacle I found in the adjoining bedroom that is off and I have marked this with blue tape so that's a total of six receptacles so far the ceiling find anymore okay I'm in the master bedroom right now and I'm finding that this one is also off so this is the seventh receptacle on this circuit okay this is another acceptable in the master bedroom it's not part of the circuit that I'm working on right now because it's hot my tests have revealed that there are seven outlets on the circuit that I'm going to be changing out now I need to find out which one of the receptacles on this circuit of seven receptacles is most upstream because that is the position where the ground fault circuit interrupter is going to go it's going to go on the most upstream reset now your first thing you do is look and see which receptacle is closest to the main panel and nineties 5 percent of time I'm telling you just as an electrician that's the way we wire things this would be my guess but I also have a very nice tester here this is the ideal sure test circuit analyzer and what I'm going to do is press this down button see we get out we are getting 122 point 7 volts right now good strong voltage now we're at voltage drop ok voltage drop is currently 4.9 percent ok the voltage load is 116 points 6 voltage load and the amps is 15 amps see I'm testing at 15 amps now I could change it to 20 amps where you get six point five percent drop and I could change it to 12 amps where you get three point nine percent drop well let's put it on 15 this is this a maximum look this is a 15 amp circuit so this would be like a skill saw this is Billy I like using a skill saw on this receptacle so this is a heavy load for this circuit so what I'm going to do on my blue tape here I'm going to write down four point nine percent big V little D voltage drop four point nine percent voltage drop and the receptacle that has the least voltage drop should be the most upstream receptacle being the receptacle where you would want to put the ground fault circuit interrupter so I'm gonna go around and I get all the voltage drops of all seven receptacles and it's gonna tell me a story testers like this if you use them enough they talk to you they tell you things you know so I'm gonna go around see what's see what's happening with each perceptible this adjacent receptacle with a 15 amp load is 6.7% voltage drop this one is 8.2% voltage drop at 15 amps so I've written that down this one in the adjacent bedroom is 10.5% voltage drop at 15 amps this one is 12.5% this one is 14.5% voltage drop at 15 amps and here we're at the last receptacle the seventh receptacle on the circuit and we have 13.9% voltage drop at 15 amps this receptacle here this is the first one I looked at it's the one that's closest to the main panel and it has the least voltage drop at 15 amps if I was a bad man I would bet that this is the most upstream receptacle of the seven before I start replacing receptacles I should mention that my plan is to put the GFCI receptacle in the circuits most upstream location then I'll install six new grounding type receptacles in the other six locations this will give GFCI protection to the sixth downstream receptacles let's consult the NEC to see what it has to say about this here we are at NEC code 406 point four to be a non grounding type receptacle shall be permitted to be replaced with a ground fault circuit interrupter type of receptacle these receptacles or their cover plates shall be marked no equipment ground an equipment grounding conductor shall not be connected from the ground fault circuit interrupter type receptacle to any outlet supplied from the ground fault circuit interrupter receptacle see a non grounding type receptacle shall be permitted to be replaced with a grounding type receptacle where supplied through a ground fault circuit interrupter we're grounding type receptacles are supplied through the ground fault circuit interrupter grounding type receptacles or their cover plates shall be marked GFCI protected and no equipment ground visible after installation an equipment grounding conductor shall not be connected between the grounding type receptacles the first thing we're going to do is turn off the circuit breaker [Music] next I'll do a double check with my fluke voltage sensor the voltage sensor agrees with the receptacle tester that the electricity is off so now the task is to remove all seven of the old receptacles on the circuit my technique now is to spin the terminal screws off with my impact driver which leaves the copper wires undisturbed while removing the outlet now I vacuum out the old bonds after a few years can be quite dusty I'll move to the second receptacle after double checking the outlet I'll spin off both of the old flathead screws and pull out the old two-prong receptacle this outlet is what we call a backstab receptacle I'll use my diagonal cutters and cut the wires flush with the back of the outlet after I cut the wires flush I'll strip new ends on them this is what the old two-prong outlet looks like once you've cut the wires now I'll vacuum out this box I'll repeat this procedure for the other five outlets on the circuit the next step is to put wire connectors and all the wires and I'm going to turn the circuit breaker back on and then I'm going to make a test with my voltage detector to see if one of these black wires is hot if it is that means that this is the most upstream receptacle okay I have the circuit breaker turned back on and here's my fluke one AC voltage detector I'm gonna go ahead and test these various lines and here we go right there this one's hot that means that this is the most upstream receptacle right here so this is where I'm going to be putting the GFCI receptacle so now I'm going to go turn off the circuit breaker it's a very important step you got to remember turn off the circuit breaker we didn't work it on it I had to turn it on briefly to do this test but then always remember to turn it back off I turned off the circuit breaker and you see nothing's live now at double-checking on the back of the GFCI you'll see it clearly designated where the line cable goes so your hot line wire is going to go to this brass colored screw and that aligns with the short slot on the receptacle so we've got the brass colored line for the hot and then from this side this is where the neutral goes you see there's a silver screw right there and that aligns with the long slide so this right here there's one that tested hot this is your line cable right here that's why that's one of the reasons we test it we need to know that this is the line so this is the load this carries the electrical energy into this box and the load carries the electrode energy to the next receptacle I'll start with the neutral and put it to the silver terminal don't tighten it up securely I'm going to want to make all these connections very secure because even though we started out with four point nine percent full tooth drop you've got a lot higher as the circuit went along so now I'm going to put the hot wire in on the brass colored side I'm going to tighten that up real good so every connection until I make real solid now we take off the yellow tape here okay so put that right in there like that here's the hot wire for the load okay get that tighten real nice I'm not using the green terminal for the ground wire we'll just tighten that down okay so our first receptacle is installed the GFCI here we are at the next receptacle put Wagle Evernote on here I like the wiggle there were nuts in this can this situation because they use the absolute least amount of space so here I'm going to put a pigtail in to the wiggle lever nut and then the pigtail is going to go on to the silver terminal goes around the terminal in a clockwise manner like that crimp it down tighten her up okay so then I take the black hot conductor prepared a pigtail put that right in there and they take that and go around either one of these terminals it doesn't matter they're two hook together and then down securely here you can see that the continuity of the neutral wires does not depend on the receptacle if mechanical damage were to occur to the receptacle electricity would still flow through the neutral wires back to the main panel and because I also pigtailed the hot wires in the event of mechanical damage to the receptacle electricity would still flow to the downstream receptacles on the circuit I installed grounded receptacles in the remaining five boxes in the same manner okay I'm gonna go ahead and turn on the circuit breaker there you go okay I've got the circuit breaker on now and here we have one green light that means open ground you have to expect that because there's no ground I mean this is a proper receptacle because the CFC is per code and everything but you just get one green light that's what you get I'm going to take that out now I'll plug in my sure test circuit analyzer and I'll get two new readings for each of the new receptacles the first receptacle which is the GFCI reads 40.6% voltage drop at fifteen amp load and that's down from four point nine percent before I replaced the receptacle and the no load voltage is 122 volts AC will be watching the no load voltage to see if that drops at all as we go along now the second receptacle now reads 6.5% voltage drop at fifteen app load down from six point seven percent with the no load voltage still at 122 volts ac the third receptacle on the circuit now reads eight percent voltage drop at a 15 amp load down from eight point two percent with the no load voltage at 121 point nine volts ac the fourth receptacle on the circuit now reads nine point nine percent voltage drop with a 15 amp load down from ten point five percent with the no load voltage at 121 point two volts ac the fifth receptacle now reads eleven point seven percent voltage drop at a 15 amp load down from twelve point five percent with the no load voltage at a hundred and twenty two volts ac the sixth receptacle now reads 13.6% voltage drop at fifteen amp load from 14 and a half percent with a no load voltage at 121 point nine volts AC and the Sabbath and most downstream receptacle on the circuit now reads 13.8% voltage drop with the fifteen amp load down from thirteen point nine percent with the no load voltage still at 122 volts ac so the no load volts AC really didn't drop as we are progressing along the circuit now after testing to see that all of the downstream receptacles turned off after pressing the test button on the GFCI I'll place stickers on the receptacle cover plates as outlined in the NEC the GFCI receptacle gets a no equipment ground sticker and the grounding receptacles get both that GFCI protected sticker and a no equipment ground sticker in conclusion I think this was an excellent project with the benefits of getting rid of the annoying two prong receptacles as well as a couple of non-code all three prong receptacles the voltage drop at fifteen amps load was reduced for every replaced receptacle and the old backstab receptacles were eliminated I'll put links in my video description for the ideal circuit breaker finder set the fluke voltage detector the ideal sure test circuit analyzer the DeWalt cordless or corded vacuum which is very valuable for an electrician who needs to vacuum while the electricity is off Dewalt impact drivers waggle lever nuts in the two three and five connector sizes as well as the variety packs Levithan slimline GFCI receptacles which are 25% slimmer than other brands and last but not least Levithan Decorah receptacles thanks I hope this video was helpful [Music] [Applause] [Music]
