- 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").
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 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
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!!!
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.
This is to the point and interesting, without the fluff that a LOT of random science/experimentation channels have. Nicely done.
Great job! Thats an intesting idea - to explain how usual things work. Hope to see more videos like this :)
Good electrician, still has 9 fingers. Thanks for the video - v.good

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.
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.
Thanks for taking the time to show us all these things... 2 thumbs up
Nodis iapperciatet this video. You have dun the public proud. A service to community. Nice job.
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
That's great.
How about an infra Camara to show the hot point inside the breaker?
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.
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 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
TH-cam is all.
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.
I've always wondered what them breakers looked like inside ! Thanks for sharing this ! :)
Crazy to see how fast this happens! Excellent video!
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
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!
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.
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 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 .
Start at 2:28
Cheers
Real MVP!
Ty
No it starts at 0:00.
great video idea! more like this in the future?
So cool, you can actually see the arc between the contacts.
I just short circuited my light in my room (don’t ask questions. I am stupid)
Now TH-cam is recommending me a video on how short circuits work.
This is proof that TH-cam 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
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
Best video ever!! I use this to teach my 2nd year electrical class. Thanks for the content
Very very nice choose. I became an Electric Enginneer 35 years ago and have never, ever, even thought about the matter. Thank you.
Best one so far
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!
great video: a faulty water cooker tripping a circuit breaker in my home brought me here. Thx!
Awesome vid man. Really cool seeing how the insides work. Thks!
is my first time time wartching your videos, but is excellent, great explication
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.
Perfect video for anyone to understand how the circuit breaker works. Thanks!!
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.
Damn sh0enice, you've come far
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.
That was fun! I appreciate the way you got right to the topic without the long preamble.
I love the modern circuit breaker, especially Square D. Very cool
"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
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
Fantastic.Can't stop watching this video again and again I now know what am dealing with as an electrician.Watching from Nairobi-Kenya.
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.
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 cool, I have understood the function but never saw trips in action. ✅
Thank you for this, I love seeing things like circuit breakers doing their job in slow motion :)
Put a clear piece of plexi to hold it together. GREAT video!
the sound effect during breaker is too good.. HW style :)
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! th-cam.com/video/jroF43OERRo/w-d-xo.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!
ive been an electrician for 40 years and yes I did know how a breaker works but still enjoyed his vid
Thanks
your slow motion sound effects are hilarious. they sound so good.
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 !!!!!!
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
Nice video!! Greetings from Brazil!
Ulisses obrigado !
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.
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
"Até mais."🇧🇷
Nice video!
André Chaves obrigado
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.
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
The slow motion short-circuit sounds should be the noise a menu selection makes in a video game
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.
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.
This video was awesome and helped me see the picture a lot better than before. Please make more videos like this.
That is super cool!
Aaron Schwarдйфиьк
AWESOME! You answer so many questions!
I never knew I wanted to know what I now know about a circuit breaker... thanks! I’m glad I know you know.
Well done! good to see how the actual stuff work...
i never know there is kinda "thermal magnetic".
Thanks for da Vids!
That was a great video
That blue in the dead front at the end!😂⚡🃏
Great video. Loved the "Até mais!" at the end.
Very cool video nice job
The production quality is just outstanding.
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. 😜
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.
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
Me when I see my crush breaking up with his boyfriend: 4:31
😂😂
Orang indo bang?
"his" boyfriend?
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!
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.
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
He: Welding mask and gloves
Mehdi: ......
I am not an electrician and know little about circuit breaker, but I appreciate your excellent demonstration.
This is more than satisfying.
I am always memorised when I watch the clips I get with my camera, but then I watch your stuff and I'm just like,
*whoa.*
+Pure Slow Motion lol... Thank you, I have been a filmmaker since I was about 12 years old, it has taken me a very long time to build up and develop techniques I have been mostly until recently using for Blockbusters and action movies. Glad I came to TH-cam, if you ever want to collaborate on anything just let me know.
Omg. Thx for replying, I can tell by all the amazing angles and exposures for different things, that you are an expert at this lol 😊
+Pure Slow Motion ha!, Thanks !, I'm still not at Full Throttle for TH-cam yet, I'm close. Yeah I have worked on a lot of big movies which is mostly what I specialize in
That's so cool lol
Pure Slow Motion yeah if you ever want to collaborate on anything just let me know
This reminds me of the mythbusters!
Thank you for the detail and clarity. You made a terrific video.
Weirdly, watching the breaker trip has the same satisfaction as watching the bullet cam in Sniper Ghost Warrior 3 (LOL). Very informative video!
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.
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
@@breezetix Gotcha, thanks
I've always wondered. Cool! Thank you.
This video is a great teaching aid for me to show rather than explain to the apprentices how a C/B operates. Great job.
