Rim star, This is absolutely the best grounding video on KZbin! I'm recently retired Electrical Engineer and have taught electrical design for many years. It took me several years at first to finally figure out how grounding actually works! Your explanation is exactly correct. I'm pretty sure than 99% of electricians, designers, and electrical engineers do not understand what you just taught. After reading the comments, for those who think he is incorrect, think it through! If you accept this information, designing or installing electrical system grounding makes sense. Most people are taught what to do, not why to do it. Again, awesome job! Very Respectfully, Kevin

[@penandpike]

Thank you!

penandpike If you did this video, no thanks necessary. I was very pleased to see an electrical video based on knowledge!

[@checkingoutgypsymike2075]

A question for both or either. The energy the electric company sends is termed "skin effect". It is teslas plasma energy. It can be made by taking man made ac sine wave and running it thru a spark gap to turn it into ac direct. Then you can run that thru a hps sodium bulb which would be a vacuum tube spark gap, and you have plasma energy. If you take a digital thermometer and take a reading of the plasma energy in the hps bulb it'll read in the negative -900 degree range. I assume it's because the heat is used by the plasma energy that's created for powering itself. The skin effect runs down the transmission line on the outside of the highly vibrational blend of metal that's used. When it reaches the pole the transformer is on, it has a short thin jump wire wired to it. The jump wire is tied to the ground wire on one end, and the other end to the transformer. The return line is also tied to the ground wire that is considered the guide wire. Teslas tower wasn't used to send wireless electricity, it was used to draw up the earths rf energy. So it seems to me, the electric company uses the skin effect plasma energy to suck the earths rf energy out of the ground to run to the transformer and that is dumped in to the liquid via tiny wires and turned into ac sine wave and that's what we being charged for. I have zero electronic schooling, but a year of watching videos of how electronics work it seems to be the case. I've tried asking multiple electronic channels, particle and quantum physics channels and have only gotten blocked and my comments removed. Asteronx tried saying i was wrong on my information when i explained how faster than light travel works, until i proved them wrong then they blocked me and came out with a video on their "possible new theories" and so did Sean Carroll from Stanford university when i took it further and explained my theory on gravity. When i tried explaining that all that together explains how particle entanglement works, my comments got removed and i can't even post them anymore. It's all from top Dr's in neuroscience and biochemistry that explain it, quantum cooper pairs electromagnetism ect but the two i mentioned, Jordan Peterson, Bruce Lipton, Neil Tyson and others wont even discuss what their combined work adds up to. So im trying to get honest answers fro electronic experts. I posted my 3 minute video on face book, with two sermons explaining how electricity is in the Bible today and they shut my account down. Can you tell me if im right? And not from a knee jerk emotional perspective, but from a knowledgeable scientific point of view. No disrespect, but the that's crazy answer from a non knowledgeable perspective is getting old. Especially when the guy's saying that remove my comments, then later come out with videos on their new theories. If you don't know thats fine, if im wrong that's fine. But im getting tired of being called crazy when im just trying to learn the truth. If i was wrong about gravity and particle entanglement, i wouldn't be getting my comments suppressed when i explain it, I'd get explanations on how i am wrong. It seems nobody has a problem telling you when your wrong and how, but no one has done that except Asteronx, which stopped when i proved faster than light travel. Thanks for any explanation either way, right or wrong.

[@KevinCoop1]

@@checkingoutgypsymike2075 Mike, A question, if I am reading correctly, you are saying that the transformer on the pole is collecting the energy from the earth, not from a power plant somewhere else. If this is the case, knowing that the earths magnetic field is 8 hertz and our electrical system is 60 hertz, where or how is that change in sine wave frequency made? Since you have this all figured out, I am assuming that you have made your own working system and do not need the utility company for electricity. Please make a short video of it and put it on your channel that you signed up for on February 6, 2021. Just 6 days ago.

[@checkingoutgypsymike2075]

@@KevinCoop1 no sir, i got the information from Gerard Morins channel, he has a bunch of videos going over how tesla made his plasma energy. He actually had a working system before his posting stopped a few years ago. His thoughts were that the ground was a siphon for the feed and return lines. But from the keshe foundations magrav (magnetic gravity) power pack unit it makes me question if it is just a siphon. Their nanotechnology is taking particles from nuclear waste and combining them in to a safe paste. They use the paste to coat teslas coils like used in an induction stove top, and when you run a trickle charge thru the power pack it makes energy from the vibration of the coils. There's a channel invert gravity (i believe the name is correct of the top of my head) that is making a tesla steam generator, he posted an article a few days ago that was from tesla, explaining how the energy we are bombarded with can be harnessed if you haven't read it. So besides drawing out the rf energy, the skin effect running on the outside of the power lines could also be using that, like i stated im not an electrical engineer by any means. Taking into account the us patent for faster than light travel, is a double hulled craft of highly vibrational metal, which they fill the chamber with mercury at -15,000 degrees so it is detached from the solar radiation all around us, so it has no friction as it moves it implies that the energy we exist in is key to understanding how the universe works. Thru neurology and biochemistry, the understanding of quantum locked cooper pairs helps to explain it further. The wicking effect in water damage restoration, how the dehumidifier dries the air, charging it, so that when the fans blow it across the wrt surfaces it magnetically pulls out the moisture due to the energy in water. Or like ground to sky lightening, the highly charged air from the thermal energy build up in the storm clouds and when it gets strong enough it actually pulls massive volts from the earth to create the lightening. Their are many examples of what im proposing all around us, as tesla said" once you understand the energy you can see God's work all around us. Planks book the spiritual universe also leads credence to it. The 3.5 trillion volts of God's spiritual, intelligent, conscious, evolving energy working in a symbiotic exchange grounding us explains gravity. There's a channel i asked about the quantum locking and it being the explanation of gravity, i believe if you search for double quantum locking you'll find his experiment from my inquiries. I asked about the suns energy being the key to gravity and the moon being dielectric, it being stuck in the magnetic energy that has the sun and planets locked together. I watch a lot of science channels so i could be wrong on the channel name, but i believe that experiment was done by the thought emporium. I can look and if im wrong make a correction. There was a video on the keshe foundations work on green energy jubilation, i haven't looked in a while so i don't know if it's been removed. You can search the internet for magrav power pack and in images you can see how the build them and see an explanation of how they work. Do yes im saying that it seems possible to draw out the earths energy. The tower tesla had made and had to destroy was for pulling the rf energy out of the earth, buy the 3 6 9 emp like pulsation it produced was hitting the Teutonic plates and caused an earth quake. Even a common generator pulls the energy from two directions, the ground and the sky. The magnet when spun over 3,000 rpm's collect the energy and forces it across the metal to generate electricity. The readon a vertical axis generator is more efficient is because it doesn't pull the energy in and make it do a 90° turn as it's collected. Like in wiring, you don't want sharp bends in wires because a power surge can make it exit the wire, and aldo causes more heat build up do to friction. Something like that, it's been thirty years since i worked with microwave cable but that was stressed in safety meetings.

[@binaryglitch64]

This is one of the best ground explanations I've seen. I'm a journeyman electrician. *Yes the subject of grounding does get a lot deeper, and more technical, but this is sufficient for any non-electrician or first year apprentice. It's simple, easy to understand and follow, and it tells you everything you need to know to understand it on a basic level. Great vid, I'll send it to apprentices.

[@willapino6256]

Plumber here, please never connect your ground to a pipe unless its a completely dead and redundant line you wont need to work on. Grounded pipes make working on your plumbing system very dangerous if you have any electrical faults as the pipe become charged with electricity and this is the reason more plumbers die of electrocution every year than electricians. Love the video and find your way of explaining things very simple and informative but please don't tell people to connect ground to pipes it can be very dangerous.

[@RimstarOrg]

Yikes. Usually the people doing this are hobbyists connecting to a pipe for grounding for a quick demonstration or experiment and then disconnecting again. I was once attending a convention in a conference center where they connected to a kitchen pipe for a ground for a Tesla coil demonstration (a high voltage machine that produces lightning-like discharges). Now that you mention it, that was not a good idea even though it's a quite common practice. But I hadn't thought of more permanent situations for household ground as a danger to plumbers and others. In the video I'm talking about the temporary hobbyist situation, but it is in a video about household ground so I can see someone thinking of it for a permanent installation. Yikes.

[@willapino6256]

@@RimstarOrg Thanks for the reply, as someone who's worked on a large variety of houses for a large variety of people I can tell you that temporary solutions can last many years sometimes depending on the person. If its just for demonstrations or is connected and disconnected quickly then obviously its no issue, but I've met plenty of people who use videos like this to try and do things to their property that should only be done by a licensed tradesperson. In future videos if it ever arises again maybe just a quick word to let people know these connections have to be temporary for safety reasons would be nice.

[@alchemy1]

The purpose of ground was not to protect people. It is a meaningless thing to even think it is so. It was to protect the grid and the infrastructure. From what? From thunder and lighenting discharge. On the contrary it became obvious that in doing so cme with it serious danger to people. And the solution has taken on many forms and most of them has little to no meaning. All a person, an actual attentive person that is, has to do is to simply look at the whole thing, the entire picture.

I have a friend who built his own recording studio. When it was all finished, he was getting some really bad noise from the house. If you tuned on a blender you could hear it on his recordings or occasionally you could pick up radio stations. So we called in an electrician and he isolated the ground for the studio only, so it was by itself. The problem went away. He drove a copper rod 10 feet into the ground and used it for the ground. Quiet as a mouse now.

[@fikrinoh1135]

Here in Malaysia we commonly use TN-S standard since Earth and Neutral are isolated. And because of that, the household is only grounded by the planted ground rod, and that means the Earth wire is not connected to Neutral wire. So that, we use three types of breakers; Main Switch, RCCB and MCB. Main switch controls the input voltage from the main into the RCCB. The newer ones can trigger by itself during short circuit or overcurrent. RCCB protects user by tripping (or trigger) when it detects current imbalance between Live (known as HOT or Line in some countries) an Neutral (or NUL in some countries), which occurs when some current got leak to Earth. MCB on the other hand, functions just like the Main Switch but the main purpose is to distribute the mains voltage supply to the entire home. MCB has its own maximum current like 6, 10, 16, 20 and 32 amps. So, unlike main switch that trips at high current like 32 and 63 amps, MCB will trigger itself at its maximum current without depending on the main switch that trips at much higher current.

[@TechRyze]

Yep - the Internet connections, computer hardware, software, cameras and especially the Internet platforms and services are all in place nowadays. Therefore enthusiast content creators have found it worth their while to place masses of useful content online in palatable formats, such as well produced KZbin videos. That we're able to pay them tips and subscriptions, as well as them earning ad revenue, is the icing on the cake, as it can create a virtuous cycle of content creation across and within a subject. A lot of creators are even looking back at their early work from a decade or more ago, and remaking it at a high quality, with updated content. It's better than a lot of broadcast TV from the 2000s - there was a lot of trash on TV back then, and I've no idea what's on cable TV these days, as KZbin has replaced all but live TV and sports events for me.

This video reminded me of a scary night I had over a decade ago: I was awakened by a loud cracking from a wall AC unit, then I hears a smoke alarm go off in my shop. I unpluged the AC, and the smoke was coming from a fault protection strip which had three MOV's connected between E, N, and G. The MOV's had shorted (maybe exposing a flaw overlooked in these circuit/surge protectors)...pouring out smoke. I found that only -certain outlets would work, but had not discovered the problem yet. At daybreak, I took a hand telescope and looked along the power line--then I saw it! The BARE wire in the bundle of three wires was snapped! This is not simply a support cable or earth ground as many people think, but it is the Neutral line. What I had was an "OPEN NEUTRAL". When it broke some of my circuits had to complete through the actual ground in the earth, which was a high resistance to the "pole pig" or pole transformer. Thus some outlets would only dimly illuminate an incandescent 120VAC bulb. Interesting...the power company called it an "OPEN NEUTRAL" It prompted me to design an "open neutral" detector.

[@ef2b]

It helps to think of the history. Originally, there were only hot and neutral wires, no ground. In a perfect circuit, that is all you need to run the microwave. Suppose in this case there is a break in the hot conductor's insulation and it shorts to the microwave cover. That cover isn't connected to anything, so nothing happens. The microwave still runs. If you touch the cover in this situation, and if you are in bare feet or touching the sink, current will flow from the hot, through the case, and through you. You get shocked. So, if all you have is hot and neutral, you can make things work, but for many kinds of faults, the system will still appear to work, but will be dangerous. You don't know there is a problem until you touch it. When you add the grounding circuit, as he described, things get much better. Now, if the hot shorts against the case, current immediately flows and trips the breaker, giving you a clue something is wrong. The difference between an electrician and someone who isn't trained in electrical work is that electricians are constantly thinking about making things safe even when they are broken or something goes wrong. It's not enough to just make things work. The EGC (electrical grounding circuit) is all about helping to handle situations when things go wrong.

[@ef2b]

@Freddy Krueger If it's not the textbook definition, it ought to be. It goes along with the definition of the National Electrical Code being the list of all the ways humans have surprised themselves by killing themselves with electricity when they thought they were safe. But, there are more things in heaven and earth than are dreamt of in the NEC; for example, having a neutral arc even when your probe showed zero voltage before and after turning off the the circuit at the load center.

[@alexcollis737]

Excellent video. A nice clear description of the how ground and earth work in practice.

[@stager33]

two types of Grounding you need to know in house wiring 1. equipment ground is the return for fault current typically when a short occurs lets say a bad wire in a washer the current returns to the breaker box where it is bonded with the neutral to complete the path so the over current device (breaker) will trip protecting the upstream equipment 2. Earth ground is used to drain off high Current and voltages to earth (IE) Lightning it is also bonded to neutral in the breaker box house receptacles are equipment ground that are also bonded with Earth Ground Earth ground is achieved with a ground rod,grid,plate or ufer type grounding (IE) rebar or copper wire encased in concrete this is why the ground and neutral shair the same busbar hope this helps just my humble opnion

[@kennethcohan9630]

Ganesh Kumar Shetty the UK used to be Red for live, Black for Neutral and Green for earth but for sometime now it has been changed to Brown for live, Blue for neutral and Green & Yellow for Earth to make it easier for colour blind people to identify the wires. The whole of the European Union follows this convention. This only applies to new or modified installations, so it is quite confusing to see wiring with a mix of colours. Wherever the new wiring has been used on an old installation, a notice has to be displayed indicating that the new colours have been used. I think it is the convention in the US to join the neutral and earth in the panel, unlike ourselves, earthing the neutral at the transformer.

I have only one wall socket which has a good ground. I stretch an extension cord out to it whenever I'm doing high voltage stuff.

[@tommymairo8964]

There is another reason why we should literally connect the ground wire to the ground at breaker panel: if the neutral wire somewhere between the breakers panel and the transformer get disconnected, and there is a connection between hot and natural, the natural line and ground line will be charged to same potential as the hot line. You will get shocked every time you touch a metal surface that is connected to the ground line. To avoid this, you need to make sure that the ground line is literally connected to ground. So it's a good idea if you connect your breaker panel case and therefore the ground line to a literally ground.

Now we see why we have many of these poles, city water no metal piping. Lance & Patrick.

In Holland we like to standardize everthing. And we call these networks either TT, IT or TN networks. TN can be devided in 3 different networks TN-S, TN-C and TN-C-S networks. What is being explained in the video can be an IT, TN-S, TN-C-S or even a TT network. Its hard to say, as you can only see one side of the installation, but my guess would be a TN-S or either a TN-C-S network, but with a earth pin on both the household side and on the transformer side. And no RCD. What we use in Holland for house holds installations is called a TT network. The 2 letters represent a code. *The first letter* (either a T or an I). Determines how the side of the transformer is connected to earth. (The star point). And means the following: *T* represents a network where the NUL/Zero/Neutral is connected to the Earth on the transformer side. *I* represents a network where the NUL/Zero/Neutral is isolated from the earth on the transformer side. *The second letter* (either a T or a N). Determines how an user is connected to the earth (a conductor or the housing of a unit). And means the following: *T* represents that the housing is connected to the earth. *N* represents that the housing is connected to the NUL/ZERO/NEUTRAL. TT network are less safe and have a lower reliability compared to a TN network. The safety issue can be dealt with by introducing a so called RCD switch that will switch off the power to the breakers very fast and on a relative low isolation fault. This level can still be dangerous though (30mA max in Holland). RCD switch stands for; Residual Current Device or Residual Current Circuit Breaker). A benefit of a TT network is that you can distribute Power over long distances. An IT network is more reliable, in the sense of keeping everything up and running, even when an isolation fault occurs. As the isolation fault can't make a loop with the NUL/ZERO/NEUTRAL of the power source. As the NUL/Zero/Neutral is isolated from the earth. This is used on ships and/or hospitals for example. Earth and NUL are isolated from eachother. Transformer has a floating NUL and is NOT connected to ground. (NOTE: when a isolation fault occurs, it has to be solved before a fault occurs in another (2nd) fase, as this will be the same a short circuit and the breaker will trip!) TN is the easiest to setup and saves a lot of money in costs. An earth fault (isolation fault) is the same as a short circuit and will trip the breaker, due to the high current that will occur. TN-C = 2 pin socket installation, household has no earth. NUL and Earth are 1 and the same. Only the transformer side has an earth pin. TN-S = NUL and Earth are isolated. Only the transformer side has an earth pin. TN-C-S = NUL and Earth are partly isolated and partly joined together. Only the transformer side has an earth pin.

[@fikrinoh1135]

Same like in Germany. Well, I think he uses a standard between TN-C and TN-C-S since the Earth is fully joined together.

I'm from the US. My opinion is in Europe you guys use way too many acronyms! I designed electrical systems for over 30 years and was amassed when I say John Wards videos telling about your systems. It's the same thing, just different words. Pronounce aluminum and you will know what I mean. Enjoy life and be safe!

[@MathCuriousity]

@@fikrinoh1135but I read u should only bond neutral to ground at main panel or tranny but not both!!!!

[@jaykay308]

love this, thank you so much. year after year, no one explain this clearly

[@LynxDaemon]

THANK YOU. I always knew ground were very important, but I couldn't figure out how they worked. This is very clear and helped me finally understand it!

[@iamethancarroll]

THANK YOU. I'm trying to learn more about this kind of stuff (just bought my first house) and this was simple and easy to understand!

[@juha4383]

You have a smooth and a special way of explaining.. Thank you

[@RimstarOrg]

Thanks. And thanks for watching.

[@ChuckSticks1]

I’ve been researching tons of videos on why it’s important to ground my 3 prong outlet and this was this clearest explanation. Thank you.

[@jansebele1481]

Finally, after more than 3 years of electrotechnical school I know what it all can mean, thanks a lot

[@gregorysagegreene]

This is well-grounded info.

[@opera5714]

Ground has another feature. It tries to make what you are locally standing on concrete or earth at the same potential as your grounded applience. I've seen grounds between buildings have 17 or more volts difference. Seen a steel building arcing to a cast iron sewer pipe. Grounds don't offer absolute protection. You can have a broken neutral between pole and service box. Recently a little girl died when she touched an outside water faucet.

[@misternormL]

Jesus. That's terrifying. Remind me to bring my Camelbak.

[@AlexJoneses]

Thank you very much, this was a clear and concise explanation with little to no bs and was very entertaining and informative

[@glenmartin2437]

To Simulacra in the Shell - You are correct that line current is normally AC = alternating current. And this is a simple explanation. In the USA, household (residential) wiring is normally about 120 volts AC. In our small town, the line voltage is about 123 VAC. For 120 VAC. 120 VAC is only approximate. For the USA, 120 VAC has two current carrying leads, hot (usually with black insulation, though not always) and neutral (usually with white insulation, though not always- electricians do make errors). In summary, there are two current carrying leads, hot and neutral. The third wire, the earth or ground lead is either a bare copper wire or insulated green or green and yellow. This ground wire should not normally be carrying any current at all. This ground wire is there for safety, and carries current back to the circuit breaker to cause the circuit breaker to trip and turn off power

[@ja6920]

Great explanation, congrats! Now i also know why old cars with metal bumpers would lose battery charge when parked touching a fence. My guess from what you showed is that there is a potential difference between the chassis ground of the battery and the "soil ground" reached by the fence allowing electrons to escape into the earth (right?)

[@RaseditsNathium]

i think so

[@ryannicholl8661]

There's one thing you forgot. GFCI breakers detect current leaving hot but not returning into neutral and then trip if there is a mismatch, even when the amount of current is less than the normal amount required to trip a circuit.

[@chengjung5300]

This video solves part of my long-time question about how the earth can be served as a "good" conducting ground. The answer to that seems to be increasing the soil moisture to reduce the contact resistance.

[@freewoodencrosses]

In the 1950s my dad had a wire recorder (before tape recorders) It had 2 wires. One wire went to the ac input and the other wire was connected to the chassis. The radio and recorder worked fine and one day the plug came out of the wall and got plugged in backward (since these old plugs were not polarized this was possible) , everything still worked but If you touched the chassis and the radiator (which was grounded, you got 110V shock). Many radios from the fifties had the same problem. Once I was cleaning a kitchen for a friend and his radio was positioned on the top of the radiator and I turned it on to listen to music, and what happened next was (shocking) I bumped the radio and the screw on the bottom of the cabinet contacted the radiator, many sparks flew and the fuse blew to that circuit.

[@andygozzo72]

many radios had 'live' chassis, much worse here in the uk, with 240v mains, so 'all' or nearly all radios has reasonable precautions such as covered chassis fixing bolts, no exposed chassis touchable in normal circumstances, i've seen some american sets that had semi isolated chassis, only connected to one pole through a capacitor and resistor, so any shock risk is severely reduced, suprisingly only a very few uk sets used this idea .., and the ones i know of so far were all 'cheaper' brands!.... most uses physical precautions only, some better than others

[@andygozzo72]

@StringerNews1 according to circuits i've seen, a large proportion of american 'series heater' sets had a 'isolated' or 'semi isolated' chassis with no direct 'low resistance' path from chassis to any pole of the mains, only via a parallelled resistor and capacitor, these limiting possible current, and much reduced shock risk, i have at least one like this, its surprising the UK and other countries with 230v mains(yes i know the usa has 240ish supply, but thats across phases for high wattage appliances, general wall sockets are 120ish), didnt use this idea, a very few did, but vast majority not...

[@andygozzo72]

@StringerNews1 any one fatally injured by one , it must've been a directly connected chassis, not a semi isolated one, in good electrical state, not one bodged up, , i've seen quite few, plus many more of UK ones(i'm in the uk, and have 200+ various vintage radios, tvs, etc.) , from what usa ones i've seen, plus the lower mains voltage, theyre far safer than a lot of our 'live chassis' sets were, in general, but obviously you do get some nasties, i do have one....

[@andygozzo72]

one uk manufacturer made a set with a non metal chassis, used a plate of srbp/paxolin instead, even the valve/tube socket contacts were integrated into it, as well as the wavechange switch, however i think the control spindles were still connected to one pole of the mains, so you had to ensure the knobs were fitted properly(long time since i serviced it, cant remember for certain)

[@andygozzo72]

@StringerNews1 radios and tvs have had pcbs since the mid 50's , i have one of the first pcb models by philips, suffers from dry joints on the tube sockets due to too small copper pads, their second pcb models also known for dry joints but this case due to lack of solder!

[@alexyee25]

You stated that the Source of the Voltage (Transformer Secondary) is Grounded. Why doesn’t the electric current flow to the Ground wire, but instead, the electric current flows to the Hot wire? If electric current seeks the lowest electrical charge potential, wouldn't the electric current go to ground immediately, thus, the electric current is terminated to Ground right away? Also, since the Neutral wire is Grounded, wouldn't the returning electric current go to Ground immediately as well? I am very confused.

[@tedlahm5740]

I call the third prong a Safety Ground. An attempt to avoid confusion. Wonderful video, even the second time viewing it.
