[@GregSr]

I am a senior technician, self-employed in the PCB manufacturing industry. Back when I was struggling with the difference between ground and neutral, I came up with an analogy using water that helped me better understand. Imagine you had an upstairs laundry room. Of course, there would be a drain in the middle of the floor just in case the washing machine sprung a leak. But, in normal use, the water in the washing machine would go down the intended path through the drain behind the machine. The drain in the floor acts the same as a ground. It's not an active part of the washing machine plumbing but if necessary it can carry the water away to avoid flooding the downstairs. The drain behind the machine acts as the neutral because it is intended to carry the water away in normal operation.

I've been in the electrical field for over 5 years now and unfortunately my coworkers and bosses have either been lousy at teaching me things or purposely keeping me ignorant so I can't progress as quickly. It's always driven me crazy not being able to fully understand the basics of electricity and how it all works. Your videos have served me so well, I'm now so much more confident when I'm working and can't begin to show my level of appreciation for all your easy to follow, informative videos. Thank you and please keep up the amazing work. If I could make a suggestion, I would love a detailed video on the steps you would take for installing a subpanel for either residential or commercial use. Regardless, any video you make will surely be great, thank you!!

[@dazeman27]

I can relate as a commercial electrician, I get frustrated by the lack of understanding by the majority of people in the field. The reality is that it's still construction and even though you attract a lot of smart people, it's a dirty and hard job that doesn't pay enough so you have to have a lot of dopes to bend conduit and pull wires. The smart guys that know what's going on usually become alcoholics and spend their free time drinking, not reading engineering books. And the amount of BS theories and principles in the industry are extremely high, so even smart people often have the wrong information if they never studied it in school. Despite the low pay and hard work, I pride myself on knowing everything I can about electrical safety and I try to correct the incorrect information that circulates in the industry. I don't like to argue with old school electricians though so I usually just take an apprentice aside and give them the correct answer when I hear someone telling them the wrong thing. You have to choose your battles and some crusty old journeyman doesn't want to hear that it's not actually magic pixies that reside in the wall holes

[@ardentdfender4116]

Kaos & Michael Not only relate to you both but in everything you said, literally! And in that it’s a bit funny to think we are the only ones go8ng through this very thing that can often be frustrating. I’m not an Electrician, but I’ve worked around them literally my entire 25+ years in plant engineering starting out as a Gas Turbine System Technician (Mechanical) since way back when I was in the U.S. Navy. I was the Mechanical to the Electrical other half or the guys that were. We worked together, we had to, but if was often like that. I got out into the civilian world and stayed in the similar related field in plant engineering and often encountered the same thing. The exception for me was the same guys that came from a military background in the Navy at the company I worked at who took the time and some patience to explain when I was confused. Later and currently I moved on into Process Automations Control Engineering and dealing with a lot of electrical in PLC Controls and dealing with the same things as you both and in learning as it wasn’t what I started my career out in field wise. Learning the ins and out of how Field Devices are wired to Electrical Control Panel and to PLC took a lot of time and understanding and re-explanation by others that had it correctly and really knew what they were talking about or who would take the time to teach you correctly. I understand what you both go through and empathize. So I find solace in these videos as well in explanation as well learning things over again.

I took a home correspondence course before a became a tech at AT&T. I was lucky to get assigned to work with an old timer that really knew what he was doing. But I've also worked with techs that didn't know anything. They didn't know how to use a VOM or how to read diagrams, and had no knowledge of basic electricity. Then you have the really smart techs that won't teach you anything.

Paul, you are the best teacher whom I have ever run across when trying to understand the fundamentals of electricity.

As an electrical PE, it is remarkable how many experienced people cannot explain these concepts simply - or worse those who are stingy with their expertise. Thankfully, I had good mentors. But so many talented individuals at the entry-level don't get the help they need to understand the basics. I see that by reading the comments. I really appreciate your clear explanations and how generous you are with your knowledge. Please keep up the good work!

Yes most people don't know that a neutral is just the center tap of the transformer and it can carry a voltage potential to ground. Tesla himself was asked about people getting shocked from neutrals and he asked " did you ground it?"( he meant bond the neutral to a grounding electrode), problem solved.

[@celoceanicon]

This is a fantastic video and explains things very well. The one thing that is potentially not accurate, though, is that in a DC circuit the wire going from the negative terminal of the DC power supply to the negative connection of the load/circuit is called the negative or ground wire, not "hot wire". While it is correct that electrons flow from negative to positive, all voltage (difference in potential) has been dropped across the load or circuit so that there is no voltage at the negative or ground wire. The "hot" wire in a DC circuit is synonymous with the positive wire, or the wire that carries the difference in potential.

[@TubeBrowser2]

Thanks. The pic at 1:49 messed me all up.

[@eugeneoreilly9356]

The hot line in DC is the positive.The negative is called ground.There is no actual ground (earth) in a DC circuit as negative is always zero volts.

Probably the best explanation I have heard. This covers a couple pet peeves of mine. For instance, you often hear "Electricity always takes the path of least resistance." No, no it does not. This video does a good job showing people this concept. Another is that people think ground is there to save them. Again no, at least in the direct sense. Excellent video.

Great video! It raised 2 questions in my feeble head: 1) Why aren't ground wires insulated? Seems like that could potentially make them useless should they be in contact with something grounded. 2) So what happens when a hot touches a ground? You mentioned it wouldn't trip the breaker, but didn't mention what would happen.

[@robertbrandywine]

The answer to one, I believe is that ground has no voltage and neither does the ground wire that runs through the house because it is all connected. Any voltage getting on it from, say, a loose power wire would run directly through that wire to the ground. It would have no tendency to move off that wire, so it doesn't need to be insulated.

[@ozzy5368]

@@robertbrandywine Sorry, maybe my question wasn't clear. If a ground wire is touching something that is earth grounded, electricity might follow that path rather than returning to the origin. Guess it wouldn't do that since still lower resistance to the origin....answered my own question.

Keep in mind that ground rods are used mainly east side of US and in the western states with rock they do not use ground rods but use a ufer ground in which Florida is now requiring them with the Delta ground. A ufer ground is copper wire cadweld to rebar 20' in length and is encased in concrete, i.e. footers, of course this is commercial and not residential.

Hello, nice presentation. On the subject of Neutrals and Grounds, I’d like to insert something. True, electricity follows the path of least resistance, to a point. To be correct electricity follows all paths available, some carry more current due to less resistance. So, a Neutral Wire in America carry’s the Unbalanced 240 volt current back to the source, ie... generator. The ground in that system will also carry part of the unbalanced load, not as many amps as the neutral only because of resistance, ground wires are allowed to be smaller sized. Make no mistake, if you disconnect a home ground wire from the connection point and connect a multimeter you will read current flow. Just my 2c’s worth, be safe.

In India it’s 220 AC . My electric iron has a small leakage in it’s metal body. This is observed when I disconnect the ground wire. With a three pin plug having phase neutral and ground wire ( we call it earth) the residual current in the metal body travels via ground wire and makes it safe to handle. This shows that the ground wire in house hold circuit always carry some current to earth. This is because of poor insulation in motor of refrigerator, AC,Iron or toaster.

Current flows from positive to negative. While electron flow negative to positive.

@@xzy7196 I thought he could have spent more time on that. Along with how fast electrons go from negative to positive which is a crawl. I've read 1 foot every 20 minutes or so. Yet the current due to so many electrons doing this lazy ride travels at basically the speed of light.

[@farmerdave7965]

I always talk about electron flow rather than hole flow so I say current flows from negative to positive.

[@ROMANERUIZA]

I second @Adnan MX, current exists due to potential difference, and it'll always go from higher potential to lesser potential (Kirchhoff and Ohm laws expand more on this), therefore, one could say that current "flows" from positive (higher potential) to negative (lesser potential). The reason for it to be like this is found in a subatomic level, where electrons flow towards a positively biased charge and are repelled from a negatively biased charge (ie battery terminals). Every time an electron moves towards the positive charge, a "blank slot" is left behind in its previous place, having this "slot" populated by the next electron being attracted towards the positive charge. Since every time electrons move they'll leave a "blank slot" in their previous positions, one will easily notice that a given "slot" will appear to be moving from the positive charge towards the negative charge, whereas electrons will appear to be moving in the opposite way. This "blank slot moving" behaviour is described as current, therefore, the reason for it to be represented in the previously described way.

Not to be that guy but ground wires are never less resistance than neutral. Commercial wiring you generally use the conduit which has far greater resistance than copper. In house wiring they use the same gauge so it is easier to work with. Anything larger than 12GA will generally have a ground conductor up to 2 sizes smaller (6 Gauge generally has an 8 Gauge ground). The design is to provide 10x rated current flow for enough time to trip the breaker. So yes path back to the bonding bar but not because it has less resistance.

[@j5892000]

Hmm that doesn't make sense. Wouldn't copper be a better choice for ground? Is it possible that pure copper is attached to conduit when it goes into the ground?

As a electrician I always wondered how the ground wire would trip a circuit breaker due to it being hooked up to the neutral in houses but I see due to low resistance it cause the influx in amps cause th breaker to trip very nice 👌🏻

[@askandy7952]

The ground wire never has less resistance. The video is not accurate about that. In many applications the conduit is used as the ground which has a far greater resistance than copper. In larger wire applications (10GA and larger) it is very common to have the ground wire be 2 sizes smaller. It simply needs to hold current for a fraction of a second up to 10x rated load if the ground becomes the return path due to a fault and trip the breaker. It is the same gauge in residential to make it easier to work with.

[@MyNameIsMEG329]

So if I have a hot and a neutral wire light fixture and I’m trying to attach it to a lighting housing box that has hot, neutral, and exposed ground wire.

As a mechanical engineer I took circuit analysis and the professor never talked about a neutral wire. We only ever talk about the terminals of a source. One being at a higher potential and the other being ground (0V). I did learn a lot from this video.

[@leerman22]

What happens if you treat the neutral like the ground? Goes to the same place ultimately. My best guess why we don't do that is because every line has resistance, and the more current flowing the larger the voltage difference between neutral at the appliance and "true" ground, and it will tingle every time you touch a (pseudo-) grounded portion of the appliances.

You should explain that electrons flow in the direction opposite of the current flow convention. That may help some people. - or confuse them further.

[@multidayticket]

By convention, If you have a wire and a positive current is measured going from left to right in the wire, then electrons are moving right to left (opposite direction) in the wire. This is how the convention defined. In his example with the battery and light bulb, a positive current will be measured coming out of the positive terminal (cathode) of the battery, through the light bulb, and back into the negative terminal (anode). Electrons are moving the opposite direction as he shows it. Learn more about it: en.wikipedia.org/wiki/Electric_current

1024 The electron flow model (negative to positive) is thanks to Rutherford's model of the atom, where electons are assigned a negative charge and protons positive.

You just helped me understand the reason for power load balancing on each side of the bus bars in a power box. Do you explain why there's a reason you should try to equate the load on each bus bar so that the neutral going back to the power source doesn't have a ridiculous load going through it? Example: 120amps on the left bar with 0 amps on the right bar. Assuming a full 120amp load on the left bar and obviously 0 amp load on the right bar, the difference would be 120amps, thus 120 amps going through the neutral during a phase cycle. I'm assuming that would be bad, right? I know wire heats when current is passed through, so I assume that could result in a fire hazard, but that's what I'm not sure of. Seems logical enough, though. An electrician doing some work on my house (he was an apprentice working with his father that was a licensed electrician) tried to explain it to me but I wasn't 100% on the reason why it was important to balance that load. With your video, I believe I understand why it is important. Brilliant, brilliant video, sir!

But it makes no sense because the ground rod is also conected to the neutral bus bar at the breaker box. Therefore, if a hot wire comes in contact with a ground rod, electricity should just flow from the ground rod, to and through the neutral bus bar, back to the transformer, since that's the path of least resistance compared to flowing through the soil.

I learned it both ways (electron current flow and conventional current flow). I prefer to use electron current flow, probably because that's what I've used at work for more than 43 years. Yes, the hand rules are the opposite, but either way works fine. In certain applications, I find it more convenient to visualize what the electrons are doing. In vacuum tubes, the thermionic emission, and grid control is electrons. In semiconductors, I use both electron flow and hole flow. In magnetic circuits, for motion, flux, and current, I use the hand rules based on electron flow. I guess it's what ever you get used to. Either way works. I've noticed that physics likes to use conventional current flow, whereas much engineering uses electron current flow. Most of my schooling used electron current flow. The US Navy Electricity and Electronics Training Series (NEETS) was developed for use by personnel in many electrical and electronic related Navy ratings. It uses electron current flow throughout all the manuals for consistency.
