Absolutely impeccable video..very clear and detailed. I learned something today, thank you for sharing your knowledge and for putting together such an awesome video...5 stars!
As a electricien in the Netherlands i am amazed about the way this is made!A metal box(so it will conduct electrity) and a inner socket with open connections to the hot wire and neutral wire.And the earth wire without shielding! As i see this,its a shortcut waiting to happen!!And you know it,because you have to put electrical tape around to prevent that to happen..We never use a metal box with the only excepting of the breaker box in our electrical system.And even that is more and more times made off plastic.So i can proudly say that we have the safest electrical system in Europe!!
This is by design, you want any exposed hot wire to short in the box and not involve a person. By using a non-metallic box you reduce the chance of having a sufficient return path to conduct enough current to trip the breaker - allowing the possibility of an exposed hot wire to send current over a number of paths for an extended period of time (again, possibly) resulting in heat buildup, arcing, and an electrical fire.
Saved this to my playlist. Your quality in explaining and demonstration is unparalleled! I have a question, excuse my ignorance, and anyone that actually knows is more than welcome to respond. He replaced the wire between the two, which has a 3rd ground wire. That was connected to the previous outlet, and then to the outlet he took apart. Why the screw? Hypothetically speaking, if an outlet in an older home is changed out in the same manner, but there is NO screw at the box being changed, must there me a screw through the metal box into the studs, connecting the ground that is 'pigtailed'? Extremely ignorant question I'm sure, sorry. Thank you for the video! Definitely subbed!
Thanks for the video. My people in Vietnam would just said this box near other box so they must be continuity, no check whatsoever. But you, you take a step further and double check it, I really like that. It's really profesional to not assume anything and always testing before handling. Also I have a question, should the ground wire be naked or insulated?
FWIW. There is no Neutral wire in either box. It is a grounded conductor, according to the code book. All the rest is educational and helpful. Thank you for showing the value of checking everything for correct connections and voltage. Also for using a voltage detector repeatedly. These little tools are priceless. Also. Many choose to use a crimp sleeve or a green wire nut. The crimp sleeve is a much more definite connection, and takes up much less space.
Grandpa was a sparky and I inherited his tools. I now own two of these and ive never known this. I appreciate you sharing this info. Wish id have learned more and channels like this have been helpful.
@@normferguson2769 im actually looking into classes. I dont need the profession due to already being a diesel mechanic, but id like to know some of the things he did. I can afford the classes so I'm gonna enroll this year when enrollment is up.
excellent video. I love your attention to little details. It seems that very few electricians now adays take the time to wrap the outlet with electrical tape or in some cases don't even take the time to screw down the unused terminals. I have a situation in my house where the cable company is reading a about 50 volt charge back feeding one of the coax lines. The technician thinks it could be an open ground. Any suggextions would be appreciated.
I was installing outlets in an addition built onto my house years ago. Had a friend over who was a licensed electrician, he was just kinda supervising me on the little stuff. I had finished connecting the wires on one of the outlets and was folding the wires back into the box, when he snuck up behind me and clapped really loud. He had to go find a really big scraper to peel me off the ceiling that day...
A Ground wire does not give protection from lighting or power surges. It only provides a low impedance path back to the source for faults. Grounding electrode conductors (GEC) do protect against lightning and surges, but those are two different components of the grounding and bonding system of the house.
Another way to check continuity is by shorting the black and white conductors in the upgraded box and ohming out the black and white in the old groundless box.
this is also a handy trick to de-energize the branch without walking to the panel (I am not an electrician) does anybody actually do this in the field? seems like a great time saver edit: also good to map out all unmarked breakers
I think contractor in the 50's and earlier were a-holes. They made everything so complicated. Electricians didn't color code the wires and used stiff wires that are hard to bend and cut. Hell! even Ben Franklin knew about grounding. Carpenters made walls out of sheetrock and plaster instead of wood or drywall Plumbers welded everything and they all used flat head screws instead of Philips head screws. now-a-days its the complete opposite. They even have helpful youtube video's.
The most important reason for the ground is to prevent getting electrocuted by a faulty appliance. If a cable insulation inside of the appliance fails and live parts would touch the metal housing, on an ungrounded outlet the voltage would "sit and wait" for a victim to touch it. In case of a grounded housing there would be a short-circuit, tripping the circuit breaker (or blowing the fuse) almost immediatly. No chance of a person getting an electric shock. That was the reason for introducing this safety mechanism. This protective measurement was first mentioned in Germany in 1924 as a possibility, in 1932 this became mandatory in the VDE 0140 (protective measures against electric shock) which is still existent but it was modernised over the years like all regulations.
Yes, that has happened to me. I get it all wired up and then realize that I forgot the cap. LOL! The ferrules are a good idea. Also tinning the copper strands would be excellent.
@@SparkyChannel Tinning is not a good solution. There's a reason this practice is banned here since 1979. The problem is, the solder will start deform under the pressure of the screw, creating a loose connection which is also a potential fire hazard. I've seen such connections, and the wire directly fell out of the terminal just simply by gravity. It also corrodes, causing a contact resistance. If you completely solder such a connection this is not a problem, because the corrosion is only on the surface of the solder. But in this case this would be a problem. This happened several times to me that I forgot the cap. Sometimes it's not a problem when the other end of the cord isn't connected to anything yet, but sometimes....
Great video! I loved the detail. I will definitely pick up those wireless tools. Much better than hollering to my wife “Is the light off?” I think she will be very happy to no longer be involved in that process!
Thanks for the help, I have a 1942 house that I have to do grounding on in the basement. Grandpa was a navy welder and had to do a lot of electrical, he was pretty clear with the dangers of electricity.
I agree. It's best to have grounded circuits. I got scammed buying this house. All new Romex in and out of the circuit breaker panel box, but what was hidden, was it was tied into older wires that are 2 conductors and insulated with asbestos. Probably going to drill holes in my floor and run conduit to the existing receptacles in the wall, add an extension box, and just leave the old wiring dormant. Unless it just eats at me, then I am going to be taking down one side of certain walls and pulling new wire. I hate the idiot that wired this house. At least the J boxes and gang boxes are steel, but the idiot used nails instead of screws. And I can't figure out how he got them hammered so tight inside the box. Long nails too. I doubt it was a nail gun. Even so, those would not have fit inside the box either. So that's a nightmare. A saws all or reciprocating saw doesn't make it any easier. Just a little faster but a lot of sparks and metal dust.
I have a Southwire 40010S-A receptacle tester. It has one red light and two orange lights. It also has a diagram that shows what the lights read and if there's a wiring problem. All the outlets I have re-installed and tested show to be correct wiring.
Great vid. Next time just leave 12 inches of bare copper in the box with no ground and then do this: wrap the bare copper around the metal box bonding screw, then continue to the green terminal of the receptacle. That way u eliminate the extra wago, no pig tail needed, and the ground 100% continuous. Solid grounds with the least number of breaks are greatly preferable. Woohoo
At 3:00, just because the tester says that there is ground, that doesn't mean that ground was set up properly. Some idiot would just decide to connect ground directly to neutral within its own outlet, so be careful about that assumption.
Great video ! And right to thw very important point ! No wasting time showing uncrewing or screwing things and showing face ! Like other videos ! Thank you so much!
Haven't finished yet but just seen were its a two wire system. Instead of running a new wire because that's easier said than done you can also put it on a GFCI of GFCI breaker and it will pass code as well.
What if your house was built in 55 and opening up the walls and completely gutting the house is out of the picture? Is there another way to fix a two wire home with open ground?
@manletopia4801 mine was built in 61. Every single receptacle has an open ground. I installed gfci's on one complete circuit, but only one of 3 have correct wiring. Whats up with this?
Thanks for your educational video. How come you don’t wire the incoming cable at the top pare of terminals and outgoing cable on to the bottom terminal set , just like GFCI receptacle’s line and load ?
Did you check in the switch and in the light fixture. 99% of the time shorts are at the termination points of the wires, so it would probably be at either of those points.
Personally I find entering a box from the side is one of the worst ways to enter a single gang box or the center side KO on any other shallow box.. If you have a GFI, dimmer, USB or any deep device on a shallow box or cut in metal box, forget it. Your connector will make it impossible. I always try to enter from the top or bottom. However, I realize this was a mock up for demonstration purposes.
Thank you for this. most scenarios won't have people breaking open the walls to replace the wire inside the walls. The GFCI is ideal. Heres my question though, if you installed a new 14/2 on the GFCI but the electric panel doest have ground, where would the ground on that 14/2 go? Just wrap it up and put it to the side?
@@VOLTRONDEFENDER4440 Here's my scenerio. At the meter, there are two hot wires (black) and one neutral (white). The white is connected to a ground in the meter box. Those 3 wires go into the main panel from the meter panel. The two black wires are attached the the main breaker in the main panel. The white is connected to a bus bar. The Bus bar is joined with a crossing to the bus bar on the left side of the box. On the right bus bar where the white wire is connected, there is a long thick white wire that goes through the main panel and into the subpanel inside of the home. That wire is connected (white wire that is grounded at the meter box) on the neutral side. Is this supposed to be this way? Since the neutral is grounded, can the neutral be used as a ground in the sub-panel? Why or why not?
13:05 I never seen two outlets installed side by side on an open wall. With an obviously installation defect. I found an open ground on an outlet probably installed around 79, a fireplace sperates twin sockets on that wall. The ground wire is present and connected So where did it get disconnected, I guess I'll start pulling out sockets closest to and work my way out. Then again all grounds report back to the panel so I'll probably have to pull all the grounds to find which outlet it's wired in parallel to
The outlets in video are likely placed as they are in order to facilitate an example. Same outlets are used in other videos to demonstrate examples of a different problem.
Excellent video. Please, I hope you can help. How to I find the first receptacle on the circuit? I'm trying to install a afci/gfci and control all the outlets downstream.
Nice video and all but the scenario you have is the easiest of all. But no one people are likely to encounter in a older home. Would be nice do discuss alternatives like installing a GFCI outlet.
Question: my buddy of mine house is wired in the back in 60’s and has two prong receptacles in a room and needs to be changed to three prog receptacles. To help out, I would install GFCI in the home run box and identify the home run and wire that to the Line side and the other wires to the load side. Then change out the rest of the receptacles with GFCI and wire them on line side? Since no ground, if I install a ground pigtail, would that fix the “open ground”?
Think he has a video specifically on this. Think he just installed gfci on the first box from the breaker then 3 prong outlets after that with proper labeling. They still show up as open ground but are IAW code.
You fix the open ground with the text: "No equipment ground." It tells the tester (a person) to expect open ground. If you want to ground it you need to run a separate ground wire or preferably rewire completely with three wires.
Great video. I am in a new house and our hall lights stopped turning on. My Husband rested and found an outlet in the same area is an open ground 🤦🏽♀️. Do you think this method here will help get the power back on for the lights? Thx in advance.
I wouldn’t worry yet about the open ground in the receptacle close by, stuck with the hall fixture and switch first. Familiarize yourself with the basics of any multi-meter. Start at the switch and determine if you have 120v going to the bottom post of your light switch. Let us know from there 👍
Why are all the receptacles in my home (built 1993) have the neutral white wires switched, that is, the terminals on top have a black wire from one cable and the white wire from the other cable, same on bottom terminals? I guess it's ok since the receptacle tester says so and they do work. But when I changed one to an AFCI receptacle, and wired it the same way, it didn't work. I had to switch the white wires so they were across from the black wires of the same cable? I hope that's clear!
Let's say I have an old house with no proper grounding in the different outlets. Can I pull a grounding cable and connect to one of the outlet box; then from that box, connect another ground cable to other outlet boxes? The idea is to avoid to rewire the entire house.
For the first socket in each line run replace with a GFI. Make sure you put the "no equipment ground" sticker on the face plate. On the others in this circuit you can use a normal grounded type but you also need to sticker it the same plus add the "GFI protected." Both of these stickers will be included with the GFI. This is code but remember without the real ground modern electronics equipment will not be as protected as if the ground ran back to the panel. Since you speak of it being an older home suggest you start by buying a slim-line GFI because the box might be too small or tight for the normal size.
he is basically saying run it again with three wire. Thats really the best solution, albeit often impractical. GFCI is probably your next best bet if a legit ground isnt practically reached, but thats just my opinion
Thank you very much for your videos. They are so helpful for me to do my job. I am so interested on that continuity device that you are using in your video. What's the name and where can i buy it? Thanks Mr. Sparkly.
6:49 you have proven continuity but not necessarily "1 box away" There could be a box in between these two that is pig-tailed that would give that same reading.
check upstream until you find a grounded outlet. I have seen where someone replaced the metal box with a plastic one and connected the ground to the plastic box. If all of the outlets are not showing ground, check the external connection to the grounding rod.
To the transformer on the street...and depending on the system, it is going back to the generator in the power plant with points in between where it is grounded. The neutral is a grounded conductor, a so called "operational ground". That what you simply call "ground" is the "protective ground". That's the reason the NEC calls the neutral also "grounded conductor".
Good video, but I am going to pick a nit here. Your continuity test does show that the outlets are properly connected on the hot and neutral wires, but it does NOT as you assert, prove it is the very NEXT outlet. There could be 10 outlets in between, and if all the hot and neutrals were properly wired, you would get an indication of continuity.
He used the right word and spelling dude. “ASSERT : to state or declare “ - Merriam-Webster Dictionary Asset , as you wrongfully accused this guy of using , is something totally different. Put on your reading glasses! And go away ! We don’t have any use for people like you here.
@@SparkyChannel when i get stuff done i need to get it done correct. Not only do i want it done but i want to know how it works and also the correct equipment and i knows i can always count on you for that.
I added a plug in a metal box with bx to a flex house. And I’m getting an open ground even with all the ground connections spliced through and ground screws used. The only place I didn’t use a ground screw was under the house in the crawl space I just wrapped the ground around the 8-32 that the metal blank plate goes on. Do you think that is the issue?
@@zacharybarnett5609 but usually if you use the stab ins, there usually a one time use because you have too press the tabs to get the wires out which can deform/damage the tabs on the inside making the connection a lot weaker.
Hi Sparky. Very informative video. Maybe you can help me with this. I bought some surge protectors from amazon and they all have lights for protected and ground. However when I plug them into the wall outlets at home some of the surge protectors show not grounded/protected but when I plug in a different surge protector it shows grounded/protected. I bought the surge protectors at the same time from Amazon a week ago. Also, I checked the outlets with a receptacle tester and I get the two lights for correct wiring. I went around the house and plugged the surge protectors/receptacle tester into various outlets with the same results. Is it a surge protector problem or something with the house wiring? thanks!
So my house is from the 50s and all my outlets read open ground. Does that mean I have to rewire the entire house? Or can I ground each one to the metal box if available? Will that actually do anything or is the box too small to act as a ground and will it heat up and possibly cause a fire if a surge occurs?
If the box is not grounded, and you wire a ground towards it, it won't doo anything. And like you said, if there is a surge it can possibly cause a fire which I heard stories about. Apparently a workaround is too install a GFCI outlet since it finds faults without using a ground wire, or just use a 2 prong outlet. Or, the last step which will cost a bit more is just too rewire the entire house like you mentioned before. Hope this helps, cheers. :)
Neutral & ground have different purposes. Neutral is provided as a return path for the load current. Ground is provided so that touch surfaces stay at zero potential. Neutral normally carries current while ground does not. If local neutral rises above ground potential because of excessive current or poor connectivity (high resisatance), ground will not be affected and still provide zero potential at the connected touch surfaces (appliance chassis, electronic equipment cases, etc.).
I used my outlet tester in a house that I was planning to buy and found that there were no grounded outlets or GFCI outlets in the kitchen and most of the rest of the house. The sellers didn’t want to budge on their price, so we walled away from it. It would’ve taken many thousands of dollars to rewire most of that house.
@@mtafli1 It means that the GFCI is faulty, or there isn't a ground wire for the tester to create a ground fault. Some cheap GFCI outlets will always disconnect power with the "Test" button because it's not really a test button as it is simply a switch. Quality GFCI outlets will actually create a safe and contained ground fault with the test button, as is attempted to be done with an outlet tester.

Did you check in the switch and in the light fixture. 99% of the time shorts are at the termination points of the wires, so it would probably be at either of those points.
At least that has been my experience
Great video with clarity.
Personally I find entering a box from the side is one of the worst ways to enter a single gang box or the center side KO on any other shallow box.. If you have a GFI, dimmer, USB or any deep device on a shallow box or cut in metal box, forget it. Your connector will make it impossible. I always try to enter from the top or bottom. However, I realize this was a mock up for demonstration purposes.
Yeah, wondering as this was a demonstration he didn’t think about that. Great tip, though.
Fantastic work Sparky!! Thank you!
My pleasure, thanks!
If you don’t want to replace the wire you can replace it to a Gfci outlet which has the same safety not requiring ground
Thank you for this. most scenarios won't have people breaking open the walls to replace the wire inside the walls. The GFCI is ideal. Heres my question though, if you installed a new 14/2 on the GFCI but the electric panel doest have ground, where would the ground on that 14/2 go? Just wrap it up and put it to the side?
@@ShyRage1 just attach it from the breaker panel to the neutral bus bar! As normally every grounded breaker is bonded with neutral
@@VOLTRONDEFENDER4440 I thought this could only be done at the main panel and not sub panels. Mine in question is a sub panel.
@@ShyRage1 yea it can only be done to the main panel where all the breakers at the main breaker might not be at that panel
@@VOLTRONDEFENDER4440 Here's my scenerio. At the meter, there are two hot wires (black) and one neutral (white). The white is connected to a ground in the meter box. Those 3 wires go into the main panel from the meter panel. The two black wires are attached the the main breaker in the main panel. The white is connected to a bus bar. The Bus bar is joined with a crossing to the bus bar on the left side of the box. On the right bus bar where the white wire is connected, there is a long thick white wire that goes through the main panel and into the subpanel inside of the home. That wire is connected (white wire that is grounded at the meter box) on the neutral side. Is this supposed to be this way? Since the neutral is grounded, can the neutral be used as a ground in the sub-panel? Why or why not?
13:05 I never seen two outlets installed side by side on an open wall.
With an obviously installation defect.
I found an open ground on an outlet probably installed around 79, a fireplace sperates twin sockets on that wall.
The ground wire is present and connected
So where did it get disconnected, I guess I'll start pulling out sockets closest to and work my way out.
Then again all grounds report back to the panel so I'll probably have to pull all the grounds to find which outlet it's wired in parallel to
The outlets in video are likely placed as they are in order to facilitate an example. Same outlets are used in other videos to demonstrate examples of a different problem.
Great video; accurate clearly presented information.
The circuit breaker finder is a game changer
Do u connect the green one to the metal box and the green wires together then black to black then white to white
Always like the of demonstrations. Thanks
Glad you like them!
Very nice tutorial... nice job!
Thank you! Cheers!
Excellent video. Please, I hope you can help. How to I find the first receptacle on the circuit? I'm trying to install a afci/gfci and control all the outlets downstream.
I figured this out. Thanks.
Good video. But you touched on the main issue. How to fix this when it’s behind drywall.
Nice video and all but the scenario you have is the easiest of all. But no one people are likely to encounter in a older home. Would be nice do discuss alternatives like installing a GFCI outlet.
Get a gfi breaker
Question: my buddy of mine house is wired in the back in 60’s and has two prong receptacles in a room and needs to be changed to three prog receptacles. To help out, I would install GFCI in the home run box and identify the home run and wire that to the Line side and the other wires to the load side. Then change out the rest of the receptacles with GFCI and wire them on line side? Since no ground, if I install a ground pigtail, would that fix the “open ground”?
Think he has a video specifically on this. Think he just installed gfci on the first box from the breaker then 3 prong outlets after that with proper labeling. They still show up as open ground but are IAW code.
You fix the open ground with the text: "No equipment ground." It tells the tester (a person) to expect open ground. If you want to ground it you need to run a separate ground wire or preferably rewire completely with three wires.
Thank you so much this is Superb viseo I appreciate your time it Help me a lot 01-19-2024 1:27am. ⌚
Great video. I am in a new house and our hall lights stopped turning on. My Husband rested and found an outlet in the same area is an open ground 🤦🏽♀️. Do you think this method here will help get the power back on for the lights? Thx in advance.
I wouldn’t worry yet about the open ground in the receptacle close by, stuck with the hall fixture and switch first.
Familiarize yourself with the basics of any multi-meter. Start at the switch and determine if you have 120v going to the bottom post of your light switch.
Let us know from there 👍
No get a better husband
Why are all the receptacles in my home (built 1993) have the neutral white wires switched, that is, the terminals on top have a black wire from one cable and the white wire from the other cable, same on bottom terminals? I guess it's ok since the receptacle tester says so and they do work. But when I changed one to an AFCI receptacle, and wired it the same way, it didn't work. I had to switch the white wires so they were across from the black wires of the same cable? I hope that's clear!
Let's say I have an old house with no proper grounding in the different outlets.
Can I pull a grounding cable and connect to one of the outlet box; then from that box, connect another ground cable to other outlet boxes?
The idea is to avoid to rewire the entire house.
For the first socket in each line run replace with a GFI. Make sure you put the "no equipment ground" sticker on the face plate. On the others in this circuit you can use a normal grounded type but you also need to sticker it the same plus add the "GFI protected." Both of these stickers will be included with the GFI. This is code but remember without the real ground modern electronics equipment will not be as protected as if the ground ran back to the panel. Since you speak of it being an older home suggest you start by buying a slim-line GFI because the box might be too small or tight for the normal size.
Yes but the ground wires must be in conduit or sheathing and all the other codes have to be followed.
Hi, I like your lecture. Thanks
You are welcome!
What do you do with plastic boxes?
he is basically saying run it again with three wire. Thats really the best solution, albeit often impractical. GFCI is probably your next best bet if a legit ground isnt practically reached, but thats just my opinion
Thank you very much for your videos. They are so helpful for me to do my job. I am so interested on that continuity device that you are using in your video. What's the name and where can i buy it? Thanks Mr. Sparkly.
Extech CT20 Remote and Local Continuity Tester: Amazon: amzn.to/2USsOgl
Thanks!
excellent video, clear and to the point, thanks.
You're welcome! Thanks so much!
6:49 you have proven continuity but not necessarily "1 box away" There could be a box in between these two that is pig-tailed that would give that same reading.
Yes, that's correct.
I have an open ground in a few outlets that have the ground wire connected to the receptacle, where would the problem be?
Good question . I'm having same problem , cannot find answer .
check upstream until you find a grounded outlet. I have seen where someone replaced the metal box with a plastic one and connected the ground to the plastic box. If all of the outlets are not showing ground, check the external connection to the grounding rod.
Great Work My Friend...
Thank you Bigmo! Cheers!
Great video sir! Thanks so much 🙏🏻
Thank you for the Detailed & Informative video.
Glad it was helpful!
Hey Bill, when you say the “neutral goes back to the power source”, I understand it goes back to the panel. Does it go anywhere else beyond that?
To the transformer on the street...and depending on the system, it is going back to the generator in the power plant with points in between where it is grounded. The neutral is a grounded conductor, a so called "operational ground". That what you simply call "ground" is the "protective ground". That's the reason the NEC calls the neutral also "grounded conductor".
Marcel Germann Thanks Marcel that helped
Great answer Marcel!
That my friends is a professional!
Thanks so much Jason!
Great video. Very informative!!!
Thank you!
Good video, but I am going to pick a nit here. Your continuity test does show that the outlets are properly connected on the hot and neutral wires, but it does NOT as you assert, prove it is the very NEXT outlet. There could be 10 outlets in between, and if all the hot and neutrals were properly wired, you would get an indication of continuity.
If you want someone to think you're smart you should learn what the word "asset" means before you try to use it in an incredibly stupid sentence.
@@waytospergtherebro - Thank you for pointing out my spelling error.
He used the right word and spelling dude. “ASSERT : to state or declare “ - Merriam-Webster Dictionary
Asset , as you wrongfully accused this guy of using , is something totally different. Put on your reading glasses! And go away ! We don’t have any use for people like you here.
gorgeous work. hell of a video
Thanks so much!
Good video! So if an appliance doesn’t have a ground wire does that mean it’s not safe?
In a word…YUP!
That was very helpful thank you.
Glad it was helpful! Thanks Jason!
@@SparkyChannel when i get stuff done i need to get it done correct. Not only do i want it done but i want to know how it works and also the correct equipment and i knows i can always count on you for that.
I added a plug in a metal box with bx to a flex house. And I’m getting an open ground even with all the ground connections spliced through and ground screws used. The only place I didn’t use a ground screw was under the house in the crawl space I just wrapped the ground around the 8-32 that the metal blank plate goes on. Do you think that is the issue?
A ground screw is dedicated to grounding a ground wire. It is not to be located where it is used to secure something removable as you’ve described.
what happens when there is no ground ito be found in othere receptacle
Who wired that outlet by plugging the wires into the back of the outlets instead of using the terminal screws?
you can use the stab ins or terminal screws but using the terminal screws instead make for a better connection
@@zacharybarnett5609 but usually if you use the stab ins, there usually a one time use because you have too press the tabs to get the wires out which can deform/damage the tabs on the inside making the connection a lot weaker.
Awesome video! Thanks so much!
My pleasure! Thanks!
Hi Sparky. Very informative video. Maybe you can help me with this. I bought some surge protectors from amazon and they all have lights for protected and ground. However when I plug them into the wall outlets at home some of the surge protectors show not grounded/protected but when I plug in a different surge protector it shows grounded/protected. I bought the surge protectors at the same time from Amazon a week ago. Also, I checked the outlets with a receptacle tester and I get the two lights for correct wiring. I went around the house and plugged the surge protectors/receptacle tester into various outlets with the same results. Is it a surge protector problem or something with the house wiring? thanks!
Interesting. Perhaps some aren't working correctly?
So my house is from the 50s and all my outlets read open ground. Does that mean I have to rewire the entire house? Or can I ground each one to the metal box if available? Will that actually do anything or is the box too small to act as a ground and will it heat up and possibly cause a fire if a surge occurs?
If the box is not grounded, and you wire a ground towards it, it won't doo anything. And like you said, if there is a surge it can possibly cause a fire which I heard stories about.
Apparently a workaround is too install a GFCI outlet since it finds faults without using a ground wire, or just use a 2 prong outlet.
Or, the last step which will cost a bit more is just too rewire the entire house like you mentioned before. Hope this helps, cheers. :)
Install GFCI outlets (do your research). Or spend the big bucks and re-wire the home.
This might be ridiculously obvious, but are the outlets all 2-prong? That is: do they lack the third prong seen on modern outlets?
Just attach black and white together and check for continuity using multimeter on the other side, why the gizmo? Something I am missing?
What if the wall is not open?
or if its more than 3 inches apart :}
Great tutorial. TY! (subscribed)
Awesome, thank you!
Another good video Sparky
Thanks Gary!
very helpful , thank you for the video
Glad it was helpful!
Great video was able to fix my issue
Excellent!
Excellent tutorial. I'm ordering the Extech device!
Thanks!
Buying a home and one thing we say on the inspection was. Open ground or weak ground in a lot of the rooms is that safe and a easy fix ???
It might be. It's hard to tell from here.
Another awesome 👏🏼 video by sparky ⚡️ thanks 🙏🏻 again.
Thanks so much! ⚡️
Thank you Sparky!
My pleasure, thanks!
What if there is a box in between the two shown that is not apparent? Maybe in another room? Will continuity test work?
if the neutral is grounded at the panel, why does the outlet test as open ground (presumably unsafe/less than optimal)?
Neutral & ground have different purposes. Neutral is provided as a return path for the load current. Ground is provided so that touch surfaces stay at zero potential. Neutral normally carries current while ground does not. If local neutral rises above ground potential because of excessive current or poor connectivity (high resisatance), ground will not be affected and still provide zero potential at the connected touch surfaces (appliance chassis, electronic equipment cases, etc.).
Very nice video ,thanks
I used my outlet tester in a house that I was planning to buy and found that there were no grounded outlets or GFCI outlets in the kitchen and most of the rest of the house.
The sellers didn’t want to budge on their price, so we walled away from it.
It would’ve taken many thousands of dollars to rewire most of that house.
Well you made an informed decision so good going!
If the Cgfi outlet trips with the test button but not the tester machine- what would cause that? This is all the outlets in the house.
@@mtafli1
It means that the GFCI is faulty, or there isn't a ground wire for the tester to create a ground fault. Some cheap GFCI outlets will always disconnect power with the "Test" button because it's not really a test button as it is simply a switch.
Quality GFCI outlets will actually create a safe and contained ground fault with the test button, as is attempted to be done with an outlet tester.
