I've been in the electrician trade for over 40 years, have you ever worked on a 2 phase/ 5 wire system? Talk about confusing, that was a nightmare until I found some old books that explained it. In the 1970s I had the misfortune of working in an old trolley car facility that was converted to a factory and it still had some of the 2 phase equipment that couldn't be replaced and unfortunately I was the only one who understood it so I got the "honor" of working on it. The company built a new facility so I didn't have to keep patching it together.

@edgarsantos4028 5 років тому

Nice explanation mate! Thanks so much.

@LeeEverett1 4 роки тому

Just a question on current flow. So, I get that it's the case that current flows negative to positive, but why do some people say that current flows positive to negative? Is that a special type of flow or something, or are they just wrong?

@saadanyaminoden721 4 роки тому

@@LeeEverett1 Its not a big deal it was just notion... Current that says it travels from possitive to negative is called the CONVENTIONAL CURRENT While the other is the actual electron flow it is called the ELECTRON FLOW CURRENT In electronics the current actually suggest the flow of electrons... but in the past they think that it is the protons that flows... and so when the notion of CURRENT has been developed, they always have the idea of it that current travels from possitive to negative... this notion has been widely accepted by the commmunity, thus all of the symbols of electrical components, like diodes, transistors and others are meant for Conventional Current... But as the years passed they discovered that the notion of current is wrong it is the electron that travels not the proton, so after they had knew this fact that electric current actually flows from negative to possitive... they cannot adopt it easily in circuit analysis because all the symbols of electronics are meant for conventional current... so if you will use the electron flow current in the circuits analysis you will have a hard time because u will need to think in reverse, for example diodes symbols is like an arrow which points its forward biase for Conventional current but if you use electron flow you have to think that the forward biase is the actually the opposite of what it points..

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 5 років тому

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 5 років тому

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.

@MichaelClark-uw7ex 5 років тому

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.

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.

I really appreciate your clear explanations and how generous you are with your knowledge. Please keep up the good work!

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.

@avimango46 2 роки тому

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.

Why is positive wire earthing out on negative earth on izuzu mu

@youtubecommentsectiondebates 2 роки тому

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.

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 2 роки тому

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 2 роки тому

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. Should I leave the ground wire not connected and just shove it back in thr box unused? Or should I connect neutral and ground wires all together in same wire clamp? And hot with hot?

@fellipec 5 років тому

How curious. Here in Brazil I was told to never connect the ground rod to the neutral wire, as it would be a bad and unsafe pratice. Never got a decent explanation, but yours make sense.

@f143744 3 роки тому

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.

6:53 The ground wire doesn't have less resistance than the neutral wire, generally. In fact some circuits will have a smaller gauge ground wire than those that normally carry current.

@nelsonjohnmichael Рік тому

I think the author was confused because most ground faults where the hot touches the casing will carry much larger currents than normal operation. This is just because the hot is touching the casing directly and not going through a highly resistive load like a light bulb.

I'm about 8 weeks in a 17 week electricity for hvar course and we never talked about this because my teacher assumed everyone knew it and after having to rebuild my electric baseboard 3 times and blowing up a transformer i just now know what these wires are and how to connect them. i wish i saw these videos before i started the class but at least once i try and rebuild my board for the fourth time now I'll understand what the wires are for and why they matter (and hopefully not blow anything else up)

@TonyPadgett 4 роки тому

Great stuff as always. 2 Questions: If someone touched the neutral part of the circuit, would they be electrocuted? If not, why? Also, What happens if someone touches the hot side of the circuit but is wearing rubber shoes and does not complete the circuit? Thanks!

@ACitizenOfOurWorld 4 роки тому

Answer to first question: nothing because the neutral is grounded at the panel so it stays fixed at the same voltage (O) as you. Second question: again nothing because the path isn't available to close the circuit through you. Notice how birds don't get electrocuted sitting on power lines..

@groundrodshorts 2 роки тому

The neutral won't shock you if it's connected correctly, but it will shock the crap out of you if it's not connected, under load and looking for a path back to source and you just happen to be it.

@KingJellyfishII 5 років тому

This is great but I have one criticism: in a DC circuit, although electrons *do* travel from the negative to the positive, we tend to ignore that and imagine that it is the other way around. And I'd prefer to call the terminals positive and negative in electrical circuits and for digital logic/electronics it's usually high and low or 5/12/3.3v/power and ground.

@DeLaCruzer11 5 років тому

One is conventional current flow and the other is electron flow version. The video is going by the electron flow version.

@heronimousbrapson863 4 роки тому

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. The current flow model (positive to negative) was, I believe, thanks to Edison, who likely knew nothing about atoms. It's too bad a consensus between the two models hasn't been decided upon.

@multidayticket 4 роки тому

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 4 роки тому

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

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 3 роки тому

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

@ROMANERUIZA 3 роки тому

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.

@jackmeijer 3 роки тому

yea, and I hope that it was just an editing mistake in the animation when the neutral and ground were connected to the positive terminal on the battery.
