@@EngineeringMindset - Would you please consider a practical description video, on how a whole home surge protector works, something akin to a Siemens FS140 device, I believe that is a type 2 device.

As a 9 Month apprentice, where should I be at progress wise in my career? They say you should pretty much be able to wire a house by yourself without a lead by 6 months. I pretty much understand everything up to service related shit, just because I haven’t been thrown into and really been shown. Just wondering coming from a true professional yourself!🤙🏼
I've been an electrician for almost 20 years now and this is a really good video for explaining the basics to students or just curious folks. I wish this sorta stuff was around when I was in trade school
Hello, I believe my ground and neutral bus is connected by the bar. Does it mean that both the ground and neutral wires can be applicable to either side of the bar without trouble? In addition, can you put a ground and a neutral into the same screw? If so does that also apply to having two ground wires into one screw and two neutral wires into another? THANKS!
You're CRAZY. I've been on RUclips since year 1 and the original videos were garbage vlogs and random stuff. It's only in the last few years that really good technical content has exploded.
It's crazy to me at 25 years old that im already old enough to say wow, i wish they had these when I was a kid! I would have been able to learn so much faster due to my adhd.
I work as an electrical wholesaler and love videos like this as I'm really just a salesman and this helps me understand what the heck my customers are talking about. thank you!

Just wait. You will come to find AFCI's can be the bane of your existence. Some are so sensitive you can't plug or unplug a vacuum cleaner in a master bedroom with out the SOB tripping!
Wow each time I previously watched videos about main panel installation, I’d have more questions than answers, but your presentation answered everything, in the right order, fantastic. Highest quality video 👍🏽👍🏽
I only wish this type of useful information, on so many different trades, was available when I was a kid. The doors that this video in itself opens, for curiosity, is amazing. It’s not too complex, and definitely something that would have grabbed my attention as a child to lead me into one of these trades. Great video, and thank you for the useful info!
I work with a lot of electronic circuits over the years as a field engineer on medical devices, but I never delved into electrical for housing. This was extremely interesting and pretty simple when you get right down to it. Great video.
im currently an apprentice for a commercial electrical company and i have always struggled to understand whats actually going on in these panels. I took notes from this video and it really helped me

These videos have somehow achieved an unmatched level of informational digestibility. I say somehow because I’ve seen the same topics explained in what I thought was a similar manner, yet have never been able to comprehend & understand the presented information as efficiently as I’ve been able to with these. For example, I don’t think I’ve ever seen such a quick & simple, yet understandable explanation of the 120/240v relationship regarding the transform’s center-tap & the connected common rail. Clear & simple gold.
I think every circuit in the home should have a GFCI breaker. Maybe there is some disadvantage I'm not seeing but why don't they? Is cost the only reason?
@@levelup1279 I think the price is the main reason. Also, in UK such breakers called RCD (Residual Current Device) and placed not 1 for a room, but one breaker for a full house. In such case full house if protected. I see no disadvantages when it comes to a human life safety)
@@levelup1279 A GFCI won't save you if you stick a fork in the outlet without being grounded. It only works if it sees a different current back from the load than what was sent. What is good (especially if children are present) are tamper resistant receptacles that have a little doors in the slots that only open when both hot and neutral plug pins are inserted at the same time. It's residential code around here.
Thank you so much for what you do! I'm learning so much about the trades now thanks to your videos. I took these classes in school and never understood a thing. You're doing a great service to tradesmen and others alike.
Quality vid Awesome narrating., reminded me of the days where you can only get these information in a classroom… the lights turns on and the teacher testing us if we’ve learned anything.
This is by far the best video I've seen describing the main panel operation. Great jo There's information on breakers, GFCI, AND AFCI breakers. It ever talks about how switches and lights are wired. It's like three or four videos in one. Great job.
Accidentally I come across your video before i know I find my self studying Electrical and changing my career because for years I wanted to work or doing business in renewable energy thanks to your hard work I can see my dream are coming true.
My daughter works at Eaton Corp. in one of the factories that makes these electrical boxes. It was kinda nice seeing something we can identify with, even though neither of us are electricians.
Excellent info and much needed. Thanks for taking the time and sharing the knowledge with us on this much needed subject matter. It is very much needed and appreciated.
Great video. One correction: I believe the the grounds from the circuits are supposed to connect to the ground bus bar, not the neutral bus bar. And the grounding rod is supposed to connect to the ground bus bar. This is especially important in a sub-panel, where the neutral and ground bus bars are not connected to each other.
In general, yes that’s true. It depends on the ground fault protection of the circuit. You wouldn’t want to have your neutral bonded to ground downstream of your ground fault protection, as it would cause the breaker with said protection to constantly trip with virtually any load. For residential circuits this shouldn’t be too big of an issue though, since you only really see dedicated ground fault protection on the GFCI outlets. In commercial and especially industrial settings though, ground fault protection is very important and it’s therefore important not to bond your neutral and ground downstream of the protection.
You are correct about the subpanel. The video is correct and by code. When the service disconnect (Main Breaker) is in the service equipment panel then by code you need to terminate the grounded conductor (Neutral) on the neutral bar, and connect it to the ground bar and panel. It is important to connect the grounds and neutrals together. If you watch the video closely, in an event of a ground fault the current is going to travel the ground wire to the panel to the neutral back to it's source. If your main disconnect is at the meter then you would connect the ground and neutrals together and then separate it at the main panel. Electrician U does a get video on why you separate the grounds and neutrals in the subpanel.
My first home was a 100 year old farm house that had been “farmer” built and engineered. No code was followed. I decided to change the front porch light fixture. So I turned it on with the switch, saw the lamp go on, the shut it off, the light went dark. So now I can safely remove the old fixture, right? WRONG! I put a screwdriver to the wire and received a good shock! Why? I was not wired correctly. Basically when the switch was off, it was just grounding it out. The fixture stays hot all the time. Beware. That’s why you use the breaker when working on a circuit you know no history on. It worked like that for years and the old saying if it’s not broken, don’t fix it is what farmers live by
This was an awesome video that cleared up a lot regarding 220v vs 110v in a breaker box. Thanks for such a clear and concise way of explaining this. I just subscribed.
Now I understand why my house is so complicated, my country use UK-like electricity but my consumer unit is using US components. And wire color code is all over the place.
I love these animation graphics...really helps me better understand it all... Now I have a better idea of how it works when you wire a generator into the breaker panel...I guess the neutral doesn't matter that it goes back to the transformer because it can't hurt linemen but obviously the breaker must be OFF so no hot wire get fed back into transformer and street lines
Am I first? Btw great video as usual. These videos are very beneficial for us school students as we can learn more that what our school teaches in India. Love from India TEM!
"which the electricity company will use to invoice the property" is the most proper way I've ever heard "which the electric company will use to fuck over the customer" ;) great video love the content!
5:09 my only comment would be reflecting your earlier statement for a future video, but separate your Grounds and Neutrals now to make the lives of yourself, or anyone else in the future, much easier. When you put in a battery backup we usually create a new first means of disconnect, meaning that you have to unbond those bars and separate the grounds and neutrals.
Thanks for the great explanation. So for the last point made do I have this right? Say we have a house that was plumbed with copper pipe. Then some years later a renovation was done which replaced some of the copper runs with PEX. If the 2nd floor still had all copper pipes within it's walls, but it was being fed from the basement using PEX, then technically those copper pipes on the 2nd floor could be energized if an electrical wire made contact with them.
Where I am in Argentina (220V/50Hz) many houses have no earth. Some do have it (I have installed a stake in ground) but they never have earth connected with neutral in the panel. Would love to see explanations of non-US AC systems.
Just want to mention, homes that have city water will normally use the water main as the primary system ground instead of an earth spike. Since the water line is copper and is in firm contact with the earth, it works just as well as a grounding rod.
What country are you in that is using copper for water mains in the street? I'm Britain, where his accent is from, we use plastic piping in the street, plastic in the homes. It's been like this for a couple of decades. I'm not sure if he's being generic in his board or for American, because he's talking about 120 and using double positives to make 240. I'm not an electrician. We have had to adapt wiring to this reality. You can no longer trust copper piping in a home will be continuous or lead back to a central area. It can be changed at any time and the copper circuit can be broken. For this reason Earth cables are being run directly from the front to the back of the properties using the main electrical board for the main earth point. Push fit plastic piping is so quick now, and they just need a small little blade cutter to cut the pipes to the right size. It's flexible and so easy to move around. Copper is much more expensive, difficult to bend, more time to cut, but the joints are a little bit cheaper. However plastic push fit connectors can be easily undone just with a click of your fingers.
Would like to see a video for panels on small generators (not connect to a grid) and on AC electrical systems on ships and how they might differ from the North American grid and the European grid panel designs or requirements. (if there any differences)
Gorgeous video. From an electricity flow stand point the neutral and ground bus bar is correct. But as far as a mechanical design, the neutral bus bars should be said to be insulated from the metal enclosure and the ground bus bar should be separate. In the video there is the green bonding screw of the one neutral bar which is awesome for the main panel design
But I have seen some "hack job" panels where a person did install grounds in the neutral bar, but this is terrible practice for multiple reasons, one being if you were to wire a sub panel this way it ties all non current carrying metal parts of the system inculding - electrical boxes, light fixture trims, even switch plate screws to the neutral and now a person can become part of the return path for current. Absolutely needs be separated. I have been shocked terrible due to this poor wiring on a farm. In a tight spot I sat down on a gasoline dispenser frame grounded to earth and then touched the electrical box. WHAMMO! There were compound issues, but the major one being the grounds and neutrals ties together on the neutral bar
I'll refer you to check the NEC, it is perfectly acceptable to connect both ground and neutral to the same bus bar, in the main panel only, as long as there is no sub panel. It is good practice to separate, but it doesn't have to be.
Well I won't argue with Code and Im not familiar with it as I'm Canadian. I'd assume it's not ok in Canada since it's never done and if I did it I guarantee it would fail inspection. The CEC Canada Electrical Code is pretty much adapted from the NEC. Just like stabbing wires into the back of a receptacle, switch or device. Maybe be acceptable, but should not be done as it's sketchy as far as what can happen. That said in the parameters of what you showed for the US, I apologize for any assumptions with regard to your wonderfully depicted video.
In a perfect world, only electricians wire electrical installations. So we are already beat with DIYers. But if a diyer saw that a panel has grounds and neutrals installed in a panel and then did a sub panel, that very leading way of wiring would cause some large problems. I fixed two panels with the bonding screw left installed in panels on different jobs in the last month 😬. In one situation a kid got hurt.
we have in Russia and throughout Europe the voltage standard in the network is 220-240 volts between phase and zero. But between 2 phases in a three-phase voltage of 380 volts.
Breakers are very important for fire safety. Always buy from reputable vendors and make sure the breaker has been approved by the competent authorities. There has been an influx of cheap breakers that are jut a plastic case and a switch lately. Especially since the economy is in tough times.
Good question! My dad was an engineer and he'd always be dismantling and fixing stuff, showing me how it worked. As a kid I became almost obsessed with understanding how things worked, and would spend every second in the garage building things and trying to repair broken stuff. I would always try to visualise how things were working, and that's basically how I make these videos. I just turn my vision into animations and share them. I really enjoy helping people understand something that seemed so incredibly complex and knowing I've made a difference to people all over the world.
Nice video. An explaination why the neutral and the earth are connected together would be helpful. Think we would say a TN-C-S system. Greetings from Germany.

It's been like this for a couple of decades. I'm not sure if he's being generic in his board or for American, because he's talking about 120 and using double positives to make 240. I'm not an electrician.
We have had to adapt wiring to this reality.
You can no longer trust copper piping in a home will be continuous or lead back to a central area. It can be changed at any time and the copper circuit can be broken. For this reason Earth cables are being run directly from the front to the back of the properties using the main electrical board for the main earth point.
Push fit plastic piping is so quick now, and they just need a small little blade cutter to cut the pipes to the right size. It's flexible and so easy to move around. Copper is much more expensive, difficult to bend, more time to cut, but the joints are a little bit cheaper. However plastic push fit connectors can be easily undone just with a click of your fingers.
Great video! Very informative and well explained.
Hello my friend, the video was great. I am an electrician and I have an electrical training channel and I do the wiring of industrial switchboards.
Would like to see a video for panels on small generators (not connect to a grid) and on AC electrical systems on ships and how they might differ from the North American grid and the European grid panel designs or requirements. (if there any differences)
Fantastic video! Thank you for sharing!
Very informative! Great video. Thank you!
Gorgeous video. From an electricity flow stand point the neutral and ground bus bar is correct. But as far as a mechanical design, the neutral bus bars should be said to be insulated from the metal enclosure and the ground bus bar should be separate. In the video there is the green bonding screw of the one neutral bar which is awesome for the main panel design
But I have seen some "hack job" panels where a person did install grounds in the neutral bar, but this is terrible practice for multiple reasons, one being if you were to wire a sub panel this way it ties all non current carrying metal parts of the system inculding - electrical boxes, light fixture trims, even switch plate screws to the neutral and now a person can become part of the return path for current. Absolutely needs be separated. I have been shocked terrible due to this poor wiring on a farm. In a tight spot I sat down on a gasoline dispenser frame grounded to earth and then touched the electrical box. WHAMMO! There were compound issues, but the major one being the grounds and neutrals ties together on the neutral bar
I'll refer you to check the NEC, it is perfectly acceptable to connect both ground and neutral to the same bus bar, in the main panel only, as long as there is no sub panel. It is good practice to separate, but it doesn't have to be.
Well I won't argue with Code and Im not familiar with it as I'm Canadian. I'd assume it's not ok in Canada since it's never done and if I did it I guarantee it would fail inspection. The CEC Canada Electrical Code is pretty much adapted from the NEC.
Just like stabbing wires into the back of a receptacle, switch or device. Maybe be acceptable, but should not be done as it's sketchy as far as what can happen. That said in the parameters of what you showed for the US, I apologize for any assumptions with regard to your wonderfully depicted video.
In a perfect world, only electricians wire electrical installations. So we are already beat with DIYers. But if a diyer saw that a panel has grounds and neutrals installed in a panel and then did a sub panel, that very leading way of wiring would cause some large problems. I fixed two panels with the bonding screw left installed in panels on different jobs in the last month 😬. In one situation a kid got hurt.

I'll buy you coffee one day! Thanks for the videos
Fantastic video lots of information .
Please Give a video on industrial substation and calculation.
Good Bless you.
I learned something today. Thanks
we have in Russia and throughout Europe the voltage standard in the network is 220-240 volts between phase and zero. But between 2 phases in a three-phase voltage of 380 volts.
Incredible explanation.
Thanks for this video. I've learned a lot
FANTASTIC VIDEO!!!! SO GOOD
I'm so confused, but I want to learn. Gonna have to watch it over again. lol
Great illustration
In Chicago area, water bonding is required. Learned that working in Elmhurst!
Breakers are very important for fire safety.
Always buy from reputable vendors and make sure the breaker has been approved by the competent authorities. There has been an influx of cheap breakers that are jut a plastic case and a switch lately. Especially since the economy is in tough times.
UL listing is a requirement for it to be authentic (USA)
How did you become such a great teach and what drives you to make such quality educational videos?
Good question! My dad was an engineer and he'd always be dismantling and fixing stuff, showing me how it worked. As a kid I became almost obsessed with understanding how things worked, and would spend every second in the garage building things and trying to repair broken stuff. I would always try to visualise how things were working, and that's basically how I make these videos. I just turn my vision into animations and share them. I really enjoy helping people understand something that seemed so incredibly complex and knowing I've made a difference to people all over the world.

Thank you for the imformative video which I really learned a lot about what and how to do and work electricity is.... the
Thank you for sharing! This is amazing!
Thank you very much for this. It is spot on and informative. Cheers mate!
Excellent video. Thanks very much.
Fantastic videos! Great Work and thanks!
A big thank you for this video.
Nice video. An explaination why the neutral and the earth are connected together would be helpful. Think we would say a TN-C-S system. Greetings from Germany.
Thanks for a really good video. So informative!
Great visual video
Super helpful, thank you thank you!
Can you do a video on solar PV and how it integrates into the home's electrical?
