@@fnsilly8983because you can be a licensed electrician, but not a licensed electrical engineer. Two completely different fields of expertise between electrician and engineer.

And as an electrician I'm choked that you are not aware of that. How involved are you in your job not to have this knowledge. But ok we all learn...BUT Most of all as an electrician I'm choked that you are not terrified to see him working with no safety procedures. There are special equipement to wear and rules to respect. Many people die everyday from electricity.
your choked? no, your an idiot is what you are. I am also an electrician and I know that you know nothing about electricity, the equipment (not "equipement"), or any respectable rules. 120 volts divided by 100,000 ohms of skin resistance equals 1.2 milliamps. currents between 100 and 200 ma are lethal. It sounds like you need to get more "involved" in some research before you call anyone out in the field they work in, that you don't.
People actually die from 120 volts. I'm surprised you didn't know that. 100,000 ohms is really high for skin resistance. That's the best case scenario. Also, BTW its you're (not "your").
*I love making videos like this on random subjects, but I need everybody to share, please.* The reason I don't do more of these is because they are kind of really not self-sustainable. Not enough people share them, please help me make a difference and share with your friends..
+Vision Research thanks !!, I have some other history making ideas using the phantom coming up next month, not gonna say what it is till it's posted ...😁
Warped Perception cool video, thanks for posting. Please look into some nfpa rated arc flash gloves though. Dangerous to play without them and it sets a bad example for those that don't know the dangers. They are cheap too.
WOW, that's cool. I've been an electrician for 36 years and I've never seen exactly what happens inside a circuit breaker. It makes me want to see inside an FPE breaker to find out why they DON"T trip when they should. That Square D QO breaker is the top of the line for residential panels. Some breakers will tolerate a momentary short circuit (just a quick bump of the wires) but not a QO. Great video. Just a note for anyone thinking of trying this . The mask will protect your eyes from the extremely bright arc that occurs just before contact but rubber gloves will insulate your hands from electrical shock. Leather over rubber will keep he rubber from melting from heat or getting cut.
As an electrician for nearly 24 years, I've never seen this type of demo on a short circuit or amp overload. In my experience, I've learned that when a breaker is overloaded as per your demonstration ( Hairdryer, toaster oven, etc, the contacts on that breaker would fail over time. So after addressing the problem, I would replace that particular breaker for complete assurance and reliability. If the issue is an overload, I would suggest splitting the circuit is possiable, and/or running a new circuit to the specific location where the issue exists. Thank you for this educational example.
Nice 22 years as an electrician and never got to see a breaker trip inside. Next time to create the short without the big arc in your face just use a switch :)
Also using your arc method, its easier to calculate the time between the short circuit and breaker contact separating. If you were using a switch you wouldnt be sure when the contact is made inside the switch.
Right there with you. A really cool inside look at a device we deal with on a daily basis. This will be my go to whenever I'm asked "how does this work?"
I've always wanted to pull apart old breakers. Mostly to see what gets weak over time to cause a breaker go trip even when overload isn't present. Now that I've seen this, I believe its the thermal sensor part that weakens after being tripped over and over. Thanks for doing what I've wanted to do for years.
I am an electrical mechanic tech. And I used to open the faulty components after changing them. To better understand the functionality. That helps in troubleshooting. Be safe man. And thank u for the vid
I just short circuited my light in my room (don’t ask questions. I am stupid) Now RUclips is recommending me a video on how short circuits work. This is proof that RUclips is listening from your device and recommending videos according to what you say or do around your device
Well from what I have experienced, it's FB and other apps that's are listening and then selling that data to Google,but I could be wrong. At least they got them recommendation right 🌝
We pulled apart some circuit breakers at my work (facilities engineer) the other week, and this is a really cool visualization of how they actually work. Super cool!
Well this video is pretty accurate. In test equipment usually some fixed amount of current is run and the machine will time how long it takes until the breaker trips. That's called a thermal test. We call the short circuit condition he goes over mag testing, and that's usually done by "firing" much higher current and using much more precise timing - breakers trip very quickly, usually in less than 50ms (faster with higher current). I've seen equipment that can blast gigantic breakers with over 15000 amps, and I know some go even higher than that.
I agree with all the comments . Taken a few different brands apart and stared at it wondering what happens . That was a great demonstration under real conditions . Oh yea , stay safe .
Why all the dislikes? The stereotypical editing is funny, and even with all the padding, I still got to see something cool without doing the work myself
For one, he kept mixing the videos of a magnetic trip into the thermal trip segment. I kept watching for the bimetallic strip to move and instead the magnet trip happens. Second, even though this is very informative, the lack of safety might cause some to dislike it.
My father-in-law is a retired power EE. He’s 93 and has late stage dementia. This video was great because it brought back things from his career and showed him something new. THANK YOU! And let’s avoid testing how quickly a breaker trips when you run 120 through your body. Those experiments rarely end well. 😜
Great posting! I have been a licensed electrician for thirty years. I now the methodology of how they work but have never seen the interior of the breaker when it is presented with a short to ground or an amperage overload. Thanks!
Very great demonstration! I posted a link to your video on Facebook because many of my friends will appreciate it. A while back, I did a test with overloading power strips and extension cords. Also replaced a 20A breaker with a 100A and let it run with 5 space heaters on one power strip until it completely melted down and failed. Quite interesting! But I didn't open the breaker case to see the mechanism work. Thanks again for the demo!
Sorry I forgot to put this in my first comment. Here is what happens when you overload massively, with a 100A breaker in place of a 20! ruclips.net/video/jroF43OERRo/видео.html
davida1hiwaaynet that was a great video man, that thing had me cracking up so many times, some of the funniest moments for me or when you had everything plugged in and you said the power strips rated 13 amps hahaha that was funny.
Around here, in Romania, we have fuses almost everywhere, though circuit breakers have appeared more and more. Our circuit breakers work a bit differently. When it trips, it goes all the way to the open position and gets locked there. You have to press a button to unlock it and then you can close the circuit breaker again.
Great video. I've always wanted to do this as an electrician. The breaker used is a Cutler Hammer BR series. This have a relatively slow response rate. Other brands like Cutler Hammer CH line and Square D are much faster. Would be interested in seeing a comparison of response times. Also older Federal Pacific and Zinsco brands are terrible and known to have around an 80% failure rate. Would love to see this play out too. Thanks
I remember in class our instructor explaining this and I asked, " how does the switch move, how do the internal mechanisms behave" the class laughed at me saying the instructor already said it's a relay that opens due to high current. I clarified my question and was sill met with laughter and this time with anger from my instructor. Good to know how it actually operates and that it isn't just a relay that's connected to a switch
Cool video. Some people stare at their phones looking at facebook... I stare at my phone and learn new real world things every day. It blows my mind that we have all this knowledge at our fingertips now a days.
Because normally there wouldn’t be that much exposed wire touching. Also there would be other appliances plugged in more than likely that would have an affect.
I think he means it's a replication in the sense that it's not the actual typical event that would cause a short circuit in a household, but yes, it is indeed an actual short circuit lol
Wow ! Thank you so much. It was so easy to understand. I wasn't able to understand the whole process no matter how many times my teacher and colleagues explained it. After watching your demonstration, it just clicked in my brain ! And now it's all clear to me, how it cuts out in overload and in short circuits. Thanks a lot, man.
6ms are actually 3 times less than 1 complete period (20ms on 50Hz or 17 on 60). It's insane! This time is enough for current to reach amplitude (in case of PF close to 1) but just once
MrDrunkenknight that's a great point and explains why and didn't spark every single time it tripped, so if it was in between Cycles when it tripped no spark.... Interesting
Yep... Since current is alering it has 0 points... Sparks are caused by inductance which is L*(dI/dt) - depends on inductivity and current change speed. So, if mechanical circuit breaking occurs in point when current is near 0 there is nothing to change - no sparks. So... It's quite complex physics which I don't remember exactly
Thank you for sharing this. In 10th grade I took electronic science and the instructor explained this but I had problems understanding this. Now I understand it.
Warped Perception If i recall it well, they have to work in less than 5 ms to comply with the standard. For comparison, a house circuit breaker usually trips within 16 ms, but it depends on the type (some are faster, some are slower)
instead of the thermal, I think their 2nd mechanism is a faster solenoid that trips when current returns thru the protective/Earth ground line (3rd prong) instead of the common return ground line
Here's me thanking you later. On top of getting a better chance to review the action, everyone sounds drunk as hell while doing it. Hilarious and educational!
Now I have to find more about circuit breakers. I know they have newer ones that are called spark detector or something? Thanks for showing how it happens!
I newer saw a circuit breaker that has a short circuit magnetic part of it done like this - the most common ones in slovakia have a small few turn coil that does the job. The overload bimetalic part is the same... Also i am missing a spark extinguisher chanber around the main contacts (not sure about the translation, we call in "zhášacia komora") - so it can open without catching fire even with loads that are of induction character.
Jozef Lipták yes I have seen those as well, there is quite a few different designs in United States, but as for the arc chamber, this one definitely has it. Thanks for watching and I'm glad you liked it
If I recall correctly, the arc chamber is longer as the breaker amps increases. This is to allow sufficient time for the debris to cool before getting ejected. I had a customer reset his 30A 2-pole breaker so many times before calling me that he scorched the end of the breaker and the conductors.
My brothers are electrician. He uses a Male end of a extinction cord with a 2 ft tail tied to a box with a light switch to trip breakers. We would be on a big commercial job and you could never locate the correct break... so the would use it to safely trip the breaker.
Great Idea! I moved into an old house and the breaker markings don't even come close to what the circuits actually control. I've been putting to off for over a year now, but this technique will make ID of circuits simple. I feel a little thick for not thinking of it myself. Kudos!
@@bigdickpornsuperstar Glad this tip helped you. I worked really great on older buildings where the panels weren't marked and you couldn't just go turning off breakers, because the business was open.
CD Snider wow that’s really dumb . A good electrician has the proper tools to find the correct breaker with out shorting things out. If they worked for they would have been fired first time they did that.
You're doing it wrong. Fill the tub up with water. Don't plug it in to the GFIC plug at the counter. Run an extension cord to the hallway. Enjoy super happy fun time with toaster in tub.
Not all households have an RCD, i for example don't because the building is old. And even if they do, they don't necessarely shut down the entire box. Sometimes they are only used to protect the kitchen and bathroom.
I can almost remember in great detail when I connected both + and - wire together in a house plug and inserted it into the socket wall... I was seven and that gave me a great understanding and respect of AC.
he said in his video, when he was like 2 years old or something he was obsessed with a machine and got his finger chopped off, cant remember the whole thing
Very cool. A few years back I had a breaker for my garage outlets (two circuits, lights and outlets) that would trip whenever I ran my air compressor. I didn't have to do anything else except replace the breaker with the same exact size. I believe it was 15 amp. I originally thought that the air compressor was drawing too much due to an ailing motor, but that wasn't the case. Replacing the breaker solved the problem and I haven't had an issue in the 4 years since I replaced the breaker. They do wear out occasionally.
Great and informative video! Thank you. Btw, I wish you covered the circuit breaker with anything clear like a clear plastic or whatever is safe to use (I am not familiar with these stuff) so the components didn’t tip off in the overload scenario, and to increase protection for you guys. Also, I am not sure if I just missed but I think I didn’t see any disclaimer or warnings not to try this at home especially for kids. No offense whatsoever so please don’t take this the other way around. Just some constructive criticism and all of these are just my opinion. Cheers!
Mark Anthony If you're out here smart enough to get your hands on a circuit breaker and know what to do with it, I think personal accountability overrules the need for a disclaimer. Just my opinion on the matter. I guess a disclaimer wouldn't hurt.
120 volts inst that dangerous. your skin resistance is about a mega ohm, therefore It will hurt but it wont be lethal so long as the skin is dry and unbroken.
Thanks, After all these years working and knowing what they do it's great to see now the insides works. If I an going to work on an outlet or swich box I use a cord like your, short it and I know witch breaker it is. Thanks again.
+Anthony Gemma lol. I thought it was a nice touch and it reminded me of a couple of situations that my friends have had with their girlfriends, they flipped the breaker and the girls were like " oh wow" you saved me ....lol.
super video i give it a 5 star rating, slow motion, over load and shorts explained and shown and it even has a hollywood production to it, it even tells you the operation of CB under overload (heat) and shorts (magnetic) awesome, I now know how the CB works. Now I wish everyone would made RUclips videos like this
He: Welding mask and gloves.
Me: "Huh, that's a bit exaggerated."

Electroboom would probably just replicate the short by pushing both the wires into his tongue.

... or placing both wires in a bathtub of water and using himself as a resistor to measure Ohms with an oscillator before the GFCI tripped.

Thank you for sharing this. In 10th grade I took electronic science and the instructor explained this but I had problems understanding this. Now I understand it.
What about Earth leakage circuit breakers in bathrooms? They're even faster! Would be cool to see one of those in action!
GFCI.... good idea i wonder if they are actually faster, that is a good episode idea, those save 1000's of lives im sure.
Warped Perception
If i recall it well, they have to work in less than 5 ms to comply with the standard. For comparison, a house circuit breaker usually trips within 16 ms, but it depends on the type (some are faster, some are slower)
I know, I'm not native speaker so I googled. I found two ways of saying it, ELCB and GFCI.
They work electrically - by having a balanced current transformer.
The rest is just a simple solenoid. Same arc, less overall action.
instead of the thermal, I think their 2nd mechanism is a faster solenoid that trips when current returns thru the protective/Earth ground line (3rd prong) instead of the common return ground line
He said, "até mais"?? Hahaha, awesome dude!! Great video!!

Jozef Lipták yes I have seen those as well, there is quite a few different designs in United States, but as for the arc chamber, this one definitely has it. Thanks for watching and I'm glad you liked it
If I recall correctly, the arc chamber is longer as the breaker amps increases. This is to allow sufficient time for the debris to cool before getting ejected. I had a customer reset his 30A 2-pole breaker so many times before calling me that he scorched the end of the breaker and the conductors.
Regulations are much different between US and UE. This type of breaker would not be allowed here in Belgium.
great video idea! more like this in the future?
I am definitely not getting notified of your uploads. But it's ok because I start wondering and then just stop by. :) Awesome stuff you do!
I know, I don't know whats happening, been getting a lot of complaints of no noti's showing up. thanks !!!!!!
ive been an electrician for 40 years and yes I did know how a breaker works but still enjoyed his vid
Thanks
so fast. this is a big help and protection not only for the appliances but for every lives to avoid greater damage such as fire.thanks for this video.
The slow motion short-circuit sounds should be the noise a menu selection makes in a video game
Me when I see my crush breaking up with his boyfriend: 4:31
😂😂
Orang indo bang?
"his" boyfriend?
@@5ntou saya, bang ☝🏽
My brothers are electrician. He uses a Male end of a extinction cord with a 2 ft tail tied to a box with a light switch to trip breakers. We would be on a big commercial job and you could never locate the correct break... so the would use it to safely trip the breaker.
Great Idea! I moved into an old house and the breaker markings don't even come close to what the circuits actually control.
I've been putting to off for over a year now, but this technique will make ID of circuits simple.
I feel a little thick for not thinking of it myself. Kudos!
@@bigdickpornsuperstar Glad this tip helped you. I worked really great on older buildings where the panels weren't marked and you couldn't just go turning off breakers, because the business was open.
ROFLMFAO !!!
CD Snider wow that’s really dumb . A good electrician has the proper tools to find the correct breaker with out shorting things out. If they worked for they would have been fired first time they did that.
And what if a breaker was defective? "Oh, sorry, I burned down your house because I didn't use the proper tools to locate a breaker."
Best video ever!! I use this to teach my 2nd year electrical class. Thanks for the content
I love the modern circuit breaker, especially Square D. Very cool
I would replay this over and over until i get my degree in electrical engineering!
Much more to being an electrical engineer than watching this video an infinite amount of times.
is my first time time wartching your videos, but is excellent, great explication
Damn sh0enice, you've come far
I’m so thankful for circuit breakers. I’ve had them trip in my sleep and I’m still alive with no house fires 😊
Ricky32908 ha, that's a great point
Great video now I know how it works. Its so satisfying to see the precise working of how it just saved me all the time from burning down my home.
the sound effect during breaker is too good.. HW style :)
Oooooo that's why when I drop a toster in my bathtub i have to get out and reset my circuit breaker. Lol 🔥🔥🔥vid guys!!!
MC SkyDaddy nope, in that case the RCD should shut down your entire distribution box
You're doing it wrong.
Fill the tub up with water.
Don't plug it in to the GFIC plug at the counter.
Run an extension cord to the hallway.
Enjoy super happy fun time with toaster in tub.
Not all households have an RCD, i for example don't because the building is old.
And even if they do, they don't necessarely shut down the entire box. Sometimes they are only used to protect the kitchen and bathroom.
I had another idea but I rather not share
The best thing to do is connect the toaster directly to the main feeder wires coming into your house.
That is super cool!

I can almost remember in great detail when I connected both + and - wire together in a house plug and inserted it into the socket wall... I was seven and that gave me a great understanding and respect of AC.
Thanks for opening this thing up. I always wandered why it doesn't have screws. Now I've seem the inside and how it works. Thanks.
Very cool, I have understood the function but never saw trips in action. ✅
Nodis iapperciatet this video. You have dun the public proud. A service to community. Nice job.
"Até mais."🇧🇷
Nice video!
André Chaves obrigado
That last short you can see plasma the bluish white looking tiny spheres of light that the sparks turned into. Tiny ball lighting. Freakin cool.
Put a clear piece of plexi to hold it together. GREAT video!
Super informative.
How'd you lose that finger?
he said in his video, when he was like 2 years old or something he was obsessed with a machine and got his finger chopped off, cant remember the whole thing
@@inactive-z2o Gotcha, thanks

This definition literally brought back my decade old 12 years me! What a perfect way to be overcome with acute nostalgia. ;) φ
2:57 He "double checks" that it's not plugged in while already touching it lmao
1:50 seems more concerning. Both hands dangerously close to live conductors, which aren't properly secured, in a device he's moving...
I teach electricity and I think this is an excellent representation of what's happening....and when. Nice job! If I could like this 1,000x, I would.
Very cool. A few years back I had a breaker for my garage outlets (two circuits, lights and outlets) that would trip whenever I ran my air compressor.
I didn't have to do anything else except replace the breaker with the same exact size. I believe it was 15 amp.
I originally thought that the air compressor was drawing too much due to an ailing motor, but that wasn't the case. Replacing the breaker solved the problem and I haven't had an issue in the 4 years since I replaced the breaker. They do wear out occasionally.
Do this with a Federal Pacific breaker. I doubt it will blow even in a short circuit circumstance.
Lmao !!! That is what I have heard. They don't blow until the house burns down .....lol
Just bought a house with an original breaker box full of only federal Pacific breakers. Needless to say we had a new box installed
Haha. I was just going to type this fact about federal. Hahaha
Better have a fire extinguisher handy
Ahh yes, my house had Fed Pac Fuse panel ,from the early 60s., No ground, cloth insulation wiring in tje house. Should have framed it and hung it up.
AWESOME! You answer so many questions!
when i hear your voice without your image, i think you are Tom Hanks..😁😁
thanks for the info sir.. god bless you..
Lol... Thanks. That's mainly because my voice is not warmed up, I have a lot of surgeries
your slow motion sound effects are hilarious. they sound so good.
Perfect video for anyone to understand how the circuit breaker works. Thanks!!
Very good presentation but you get your fingers close to live terminals a few times.
Great and informative video! Thank you. Btw, I wish you covered the circuit breaker with anything clear like a clear plastic or whatever is safe to use (I am not familiar with these stuff) so the components didn’t tip off in the overload scenario, and to increase protection for you guys.
Also, I am not sure if I just missed but I think I didn’t see any disclaimer or warnings not to try this at home especially for kids.
No offense whatsoever so please don’t take this the other way around. Just some constructive criticism and all of these are just my opinion.
Cheers!
Mark Anthony If you're out here smart enough to get your hands on a circuit breaker and know what to do with it, I think personal accountability overrules the need for a disclaimer. Just my opinion on the matter. I guess a disclaimer wouldn't hurt.
120 volts inst that dangerous. your skin resistance is about a mega ohm, therefore It will hurt but it wont be lethal so long as the skin is dry and unbroken.
He: Welding mask and gloves
Mehdi: ......
Thanks, After all these years working and knowing what they do it's great to see now the insides works. If I an going to work on an outlet or swich box I use a cord like your, short it and I know witch breaker it is. Thanks again.
Congrats my dear guy...I am about to show this amazing demonstration video to my electrician students!
Even when you know how things work, seeing them in action and in slow motion is so amazin thanks !
ev0wizard your welcome
I love how you put to make you feel like a man when labeling the lever
+Anthony Gemma lol. I thought it was a nice touch and it reminded me of a couple of situations that my friends have had with their girlfriends, they flipped the breaker and the girls were like " oh wow" you saved me ....lol.
I have the confidence of Tesla right now 👍🏽
That blue in the dead front at the end!😂⚡🃏
super video i give it a 5 star rating, slow motion, over load and shorts explained and shown and it even has a hollywood production to it, it even tells you the operation of CB under overload (heat) and shorts (magnetic) awesome, I now know how the CB works. Now I wish everyone would made RUclips videos like this
