- If you've ever wondered how that pesky circuit breaker Works inside when your lights turn off, then this is the episode you need to watch.
I open up a household circuit breaker and replicate a couple very common household fault scenarios, I film it with the high-speed cameras to reveal exactly what's going on inside that circuit breaker.

He: Welding mask and gloves.
Me: "Huh, that's a bit exaggerated."
Me see the state of his right hand at the end: "Umm, maybe this guy already has some experiences behind him..."
LOL...haha.. that's a good one but very true !.
Arc flash is brighter than the sun. Dude knows how to apply PPE.
In larger circuits, a jet of molten copper comes out. It’s dangerous.

Awesome I am licensed Electrical Engineer and I've never seen a demonstration of the CB internals trip like you showed before. Great work! In the name of science!
@Slim_Savagewhy would that be made up?
@@fnsilly8983because you can be a licensed electrician, but not a licensed electrical engineer. Two completely different fields of expertise between electrician and engineer.
For much of the US in order to have public works (or even residential in some states) AC distribution projects designed and built, the drawing(s) must be approved by a licensed electrical engineer registered with the state using a stamp or embossment giving the engineers name and license number (along with other information). In the US the name professional engineer implies that the engineer is licensed with the state. @@afeudale
As an electrician it is really nice to see how this physically works. I'm not supposed to take these apart at work ;)
Danny Swayze Same here. Always wondered and now I know.
Same!
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").
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 :)
Inside The Mind Of Matt very nice!!, I like the big arc, it makes for good entertainment!
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?"
keep your breakers and recover the sterling.
There is no WOW factor in using a switch. Or should I say, there is no SHOCK value, using a switch. Y'all see what I did there.......LOL!!!
Electroboom would probably just replicate the short by pushing both the wires into his tongue.
Or might even sit on it
Lol that is soo Mehdi
... 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.
HAHA that guy kills me
Ah sh*t ,f
Very glad to see that Shoenice cleaned up his act and got sober. great job man!
Haha
Lol
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
*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..
We're going to share! Right now! We love what you do with our cameras and your style!
+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 done! I thought I know what was going on in there... Fascinating! Can you try to do the same with a GFCI?
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.
Warped Perception I've been wondering about this for a LONG time and found very little, thank you for making this
This is to the point and interesting, without the fluff that a LOT of random science/experimentation channels have. Nicely done.
My struggle was so real...
I LOVE YOU MAN
THANK YOU THANK YOU THANK YOU
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
That's great.
How about an infra Camara to show the hot point inside the breaker?
Great job! Thats an intesting idea - to explain how usual things work. Hope to see more videos like this :)
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.
Good electrician, still has 9 fingers. Thanks for the video - v.good
1:44
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.
Great job. I'm an electrical engineer 15 yrs (but working in IT) only now able clearly see how it works!!! You were awesome, good job.
I just short circuited my light in my room (don’t ask questions. I am stupid)
Now CZcams is recommending me a video on how short circuits work.
This is proof that CZcams 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 🌝
Warped Perception yeah hahahah
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!
Thank you I'm glad you like that
Thanks for taking the time to show us all these things... 2 thumbs up
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 once asked my high school teacher how a MCB works and he , he sent me back 🔥.
Now I know . I don't need a science teacher
CZcams is all.
"I don't feel safe touching this.."
Touches anyway
*instinctively (they’re usually hot)
Due to it not being hot he went ahead and did
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
Don’t know why all the negativity because nobody’s gonna do this and get shocked or killed, that’s why they’re watching you!
Great video!
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. 😜
Nodis iapperciatet this video. You have dun the public proud. A service to community. Nice job.
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.
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 .
ive been an electrician for 40 years and yes I did know how a breaker works but still enjoyed his vid
Thanks
He said, "até mais"?? Hahaha, awesome dude!! Great video!!
Fabio Barros obrigado
Its not a "realistic replication" of a short circuit.... its a short circuit... wtf lol
Absolutely right😂
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
Very very nice choose. I became an Electric Enginneer 35 years ago and have never, ever, even thought about the matter. Thank you.
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!
Start at 2:28
Cheers
Real MVP!
Ty
No it starts at 0:00.
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.
Put a clear piece of plexi to hold it together. GREAT video!
I am not an electrician and know little about circuit breaker, but I appreciate your excellent demonstration.
great video idea! more like this in the future?
I've always wondered what them breakers looked like inside ! Thanks for sharing this ! :)
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.
Nice video!! Greetings from Brazil!
Ulisses obrigado !
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
Always wondered how it works to me it was a black box of secrecy
Thanks for spreading the knowledge
In fact, it does contain many patents ... Much more than I could quote.
That blue in the dead front at the end!😂⚡🃏
Damn sh0enice, you've come far
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! czcams.com/video/jroF43OERRo/video.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.
Thanks! Glad you enjoyed it! It's fun to blow things up sometimes!
I find it amusing that this is edited like an over-dramatic american tv show
LydianLights lol... That was on purpose.
Warped Perception hell Yeah lol
Warped Perception thanks man! Great video.
LydianLights This is great.
Would you rather it be a computer voice-over? I didn't see anything over dramatic at all. The guy is lively and interesting.
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.
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
Crazy to see how fast this happens! Excellent video!
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!
Lloyd Prunier your welcome
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.
great video: a faulty water cooker tripping a circuit breaker in my home brought me here. Thx!
Watch slow motion video with 0.25x speed. You'll get ultra slow motion. THANK ME LATER ✌️
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!
the sound effect during breaker is too good.. HW style :)
Great video. Loved the "Até mais!" at the end.
Flash Back to 1983. My left photo was working for GTE Sylvania Circuit Breaker Division. I designed a Thermal Magnetic Strip for a breaker and the UL Label was awarded. Breaker in production again.
The production quality is just outstanding.
Best one so far
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.
I put together a 30 video queue of circuit breakers videos and this has got to be one the coolest and in depth.
Thanks! Makes me happy to hear that my craziness is somewhat entertaining 🤠.
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 !!!!!!
Me when I see my crush breaking up with his boyfriend: 4:31
😂😂
Orang indo bang?
"his" boyfriend?
Fantastic.Can't stop watching this video again and again I now know what am dealing with as an electrician.Watching from Nairobi-Kenya.
Cool. Also nice way to illustrate the difference between over-current protection, and ground fault / short circuit protection. Especially important to know for anyone learning electric motor circuit sizing.
The slow motion short-circuit sounds should be the noise a menu selection makes in a video game
Very cool, I have understood the function but never saw trips in action. ✅
this was helpful. thank you. i was today years old when i realized you need to switch it off before turning it back on. good job.
3 suggestions. 1) use a piece of clear Plexiglas in place of the removed side, screw/bolt it together. then you can see inside without the risk. 2) put a camera that can zoom directly over the top, not at an angle. 3) super super super slow motion! other wise neat video
He: Welding mask and gloves
Mehdi: ......
is my first time time wartching your videos, but is excellent, great explication
Weirdly, watching the breaker trip has the same satisfaction as watching the bullet cam in Sniper Ghost Warrior 3 (LOL). Very informative video!
That was fun! I appreciate the way you got right to the topic without the long preamble.
"Até mais."🇧🇷
Nice video!
André Chaves obrigado
i never know there is kinda "thermal magnetic".
Thanks for da Vids!
I liked the last short where the slow-mo caught Sparks slowly leaving the picture.
This video really helped me because I had a test coming up with the question 'Explain how a circuit breaker works' so yea this really helped, thanks Warped Perception!
That is super cool!
Aaron Schwarдйфиьк
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."
So cool, you can actually see the arc between the contacts.
your slow motion sound effects are hilarious. they sound so good.
Lever: enables human tinkering and make you feel like a man. Known to evoke fear and frustration. 😆
This definition literally brought back my decade old 12 years me! What a perfect way to be overcome with acute nostalgia. ;) φ
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.
This video is a great teaching aid for me to show rather than explain to the apprentices how a C/B operates. Great job.
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.
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.
Regulations are much different between US and UE. This type of breaker would not be allowed here in Belgium.
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...
Thank you for this, I love seeing things like circuit breakers doing their job in slow motion :)
Awesome vid man. Really cool seeing how the insides work. Thks!
AWESOME! You answer so many questions!
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.
Double and triple poles have to trip the whole thing if only one leg overloads. That would be cool. Great video. My first time seeing this.
I love the modern circuit breaker, especially Square D. Very cool
That was a great video
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.
Best video ever!! I use this to teach my 2nd year electrical class. Thanks for the content
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 CZcams videos like this
