How Many Ground Fault Circuit Interrupters On One Breaker

hi guys welcome back to my channel today what i want to do is i wanted to talk about a topic that has been asked to me over and over again it's a very good question and that is why i decided i need to make a video on it because this has been a repetitive question a lot through email through instagram and through comments on my youtube page two gfi's i've had the same questions how many gfi's can you put on one circuit now i commented a while back on it and said you know you can put you know the same amount as a regular circuit so i think it's like 10 for 20 amp and eight for a 15 amp circuit so i did that i said that and i think some person emailed me and said i was wrong and a whole long spiel and then i realized that they i didn't talk i guess answer the question as i should have uh if you use more than one gf on a circuit you can't you cannot you cannot you cannot bring the main power in on the line and go out on the load and put the load back on this one it will not work like that at all and i'm going to show you prove it to you right here with this box these boxes that i have right here to preview that it won't work and i also am going to show you how to do it so you can have two gfi's on one circuit and make it so it will work all right super easy guys but i'm going to show you the wrong way first so obviously it's a two brand new gfi's got a white one a rivalry and i got a brown one both of them are 20 amp both of them have the stickers on it when i get going here they won't have the stickers on for long i'm also going to be using a green wire net if you guys are interested in how to use these because this was another good long question that i had repetitively and i made a video on it and i'll link it right up here in the corner if you guys want to watch that how to use these things i know it seems like well duh but that's what i thought too and not throwing rocks at anybody but when i first saw these i thought these were the stupidest things i was all and i didn't really understand how to use them so i was in the same boat there's all these people asking these questions so i decided to make a video anyway let's jump in here we're going to start out doing it the wrong way so method one is the wrong way if you do it like the way i'm going to do it and i'm going to i'm going to explain this to you this video might be you know 15 16 17 minute long but you're going to learn how to do it the right way but first we're going to do it the wrong way just so you guys will see what will happen so let's dive right on in here so what we have here is we have a box with the main power in it if you've ever watched any of my electrical videos you guys know that i have it on the cord just so i can keep rolling with these videos and then you have your wires going to this box right here so this wire is this wire as you guys can see this huge well you can't see at all because it's not in frame but basically it just goes from this box to this box that's all it does just jumps right over all right so normally if you don't know what you're doing and you were to wire up a gfi and let me stop right here and say that this is the only receptacle that i personally feel comfortable ever stripping and putting under the lugs i always always always tell you guys to wrap your screws around the um receptacles or switches because well you guys will know if you don't know have a video on it guess where it'll be up in that corner right there okay these receptacles in the back have clamp shells so when you screw them in they clamp down on the wire this is the only kinds of receptacles that i would ever ever ever use or switches if some switches actually have the clamp style also so just keep that in mind when i say don't ever stab in the back this time you can alright got some dual strippers here links to a lot of these tools that i'm using are down in my description area for amazon they will only help me out uh if you buy from my store it'll help me keep making these videos now let's look at this this is a green wire nut we're going to be using here in just a second what we're going to do is really really really easy and it's very helpful like i said i do have a video on this so all we're going to do is we're just going to slide this down now or normally you would never have stranded wire but for this because i have it on a little extension cord you would you're going to have a it's going to be stranded so there's really no you know making your joints up because you know what you know okay now the wrong way is this way okay so we're gonna put this under here like so and i'm going to leave these out of the box uh i don't ever ever recommend leaving these out of the box to do any testing but we're going to do it for here okay so what we got it's very easy to see because this is stranded wire so you guys will know exactly what i'm talking about when i say you know where's the power and where's the high because these are obviously uh solid and this is stranded okay so normally what you would do the line would come in and that's your hot well if you don't know where the line the load is it says it right here on the back of this gfi line and this is your load so we're gonna take us off because we're gonna use it temporarily all right so let's go ahead and we'll put the neutral zone first and then the hots all right and neutral is always silver and if you didn't know that and you're still in your color blind or whatever well you can just look here and the bigger blade and our 20 amp will have this little divot on the side but uh the bigger blade you see these two are different sizes that coincides with the neutral okay okay let's put this hot under here all right we're going to same thing now normally if this was going to be just a regular receptacle this is how you would do it because you want this one to be protecting this one this is the way a lot of people think that if you have more than one gfi in your circuit it needs to be this believe me guys is the wrong way and i want to prove it to you and i want to show you guys because up until like i said before that point i didn't have any clue that this guy that was trying to wire his bathroom was doing it and i i don't know i just assumed and you know what happens when you assume do you know makes ass out of you and me so let's see what happens here so we'll go ahead and we'll strip this out dual strippers two wires one set of strippers boom awesome huh guys pretty fantastic all right and we're just gonna wire this one like normal you know if this was a regular receptacle which because we don't know but we're getting ready to find out aren't we all right we'll do the neutral next and then the hot all right now like i mentioned this is the wrong way to do it okay so just to recap we brought our hot into the line on this one this one right here we brought our hot into the line on this one all right so hot on the line is from the panel on the load goes to this this is our load all right so here's what we're going to do we're going to plug this unit in right here with the extension cord and we're going to see what happens so we come here to our first one we're going to plug our tester in here we're going to see all right now you know that the power's on and it says correct so we'll drip it out correct right i should trip this one out and let's see if it did [Applause] yep it did so let's reset this one we have no power here guys what the heck why is that it won't drip put it a little further still no power let's get a meter and see if there definitely is no power all right so i'm just using my ideal meter here we know that the circuit is hot but we know it's hot because i told you it was hot let's use the meter and let's see if it is truly hot let's see all right all right we have 120 volts right on both let's see if we have it on both yep let's see on this one here we have nothing why is that all right let's say you get to this point and you're like i know i got this receptacle right what the heck now you pull it now you pull your receptacle out of your box so now you've got a hot live circuit which please don't ever do this i'm just showing you guys i'm just showing you guys so don't don't ever do this but let me show you that you do have 120 volts here see you you have 120 volts here you cannot feed one gfi to another gfi now this is the incorrect way plain and simple so let's be safe let's take our power off we want to double check and make sure that the power's off so we'll take this tester and we'll plug it in here even though we know it's off i mean because i unplugged it but it's completely dead now how we gonna fix this so you can have multiple gfi's on one circuit because this is just one circuit you saw me plug it in so you definitely know it's only one circuit let me show you the correct way to fix this so you can have this gfi and this gfi on with no problems so let me show you all right the problem is in their very first gfi okay what is the problem what you're doing with this gfi here you're coming you're telling this gfi on the main power on your line coming into this gfi that anything on the bottom side of these screws which is basically the ones on the back which says load anything on this need to be protected well if you already have another protective device on here uh you it just won't work i don't know i cannot tell you a scientific reason i'm just an electrician i'm not a magician but sometimes i am a magician and i can tell you how to fix this if for some reason you're watching this and you know the correct terminology and all that jazz on why that won't work then let me know i just know for a hundred percent fact i just showed you guys for one that it will not work so let's make sure this gfi is safe here let's look at this one all right so we do know for our video purposes like i mentioned this is stranded wire so we do know that the line is the top and it's right here right it's this plug right here you can see there it is so how are we going to fix it so if you want to continually put gfi's on down the line which i don't really know why you would want to i mean there's there are reasons but i don't really know why you would want to but if you did all you have to do is take your load off here so the load is this wire right here that goes up out of this box it goes up out of this box and makes a loop and it comes right back down into this box to this receptacle so we're going to take it off of this gfi right here so let's go ahead and break it loose the grounds are completely fine all right so now your load is no longer has any wires on it so now on the back here where it says load there's no wires and what you're left with is these two wires now you can do one of two things and if it were me i would do this i would take these back off make a joint put one wire under here but see what they did here they gave you a spot to put another wire on here now you can do that and we're going to just for the sake of this video but because i have a lot more videos with these receptacles and these boxes and these wires but regardless we're going to put both these whites under one screw right now right there's nothing wrong with this at all i am completely okay with putting two wires under here but for my purposes other than this video i would never do that i know why am i doing now right like i said it's just for this video purpose it's not for anything else because you know okay so now two wires under the hot tighten her up all right so now you have two wires under the brass or the hot screw two wires under the silver or the neutral screw all right now make sure we're all good and safe here all right let's plug it in and now let's see what happens because i'm kind of curious to see if it'll work i mean i know it will don't tell anybody though okay we're gonna turn it on all right we're going to put we call this a monkey or a little tester in here and we see that the lights are on all right let's trip it out okay all right now let's go to this receptacle all right you see here's the monkey it is on that's great but wait a minute we don't have it on here but we do here let's see if it'll trip out oh yeah tripped all right there you have it guys the only way to make more than one gfi on one circuit work is to put them your wires your wire going from one gfi to the next on basically on the same side so you don't use the load at all that is the only time you would do that is or if you or or if you only wanted this to be gfi and the rest of them not so basically that's the correct way the second way the first way is the non-correct way never never put a load on for another gfi it just it just won't work like that it can't you saw i just proved it so that is the way you do it right okay guys if you have any other ideas any electrical videos that you might want to see any diagnosing any troubleshooting please drop me a comment down below let me know also down in the descriptions i have all my affiliate links for all these tools that i used you can check them out there i also have now a storefront if you just want to check it out you can click on there pulls up one big page and has all my stuff on there with the pictures and everything you can click on there also shop through there super easy super convenient didn't even know i had that until just recently so it's good for me also i have an address patreon and anything else if you want to send me anything guys you know don't send me any cookies well maybe maybe send me some cookies but anyway feel free to send anything you guys want to guys if you like what you see like and subscribe god bless and we'll see you in the next one have a great day
