Fuse vs Circuit Breaker Which Blows Faster (Slow Motion)
Вставка
- Опубліковано 2 сер 2024
- In this episode I put a Screw-In Fuse up against a Modern Circuit Breaker and Film it with the High Speed Camera (super slow motion) to see which one trips faster in the event of a short circuit, a fuse or circuit breaker.
In slow motion you can also see how a circuit breaker or fuse works inside when it blows or trips.
I hope this video gave you a deeper and better understanding of how circuit breakers and fuses work inside as well as answer the viewers questions which one blows faster.
if you want to see how a circuit breaker works in general, here is the previous episode on how circuit breakers work in slow motion.

Had a lady using 3 space heaters on the same line (Multiple outlets, but same wire) and it tripped the breakre, what did she do... Turned it back on, Que 20 minutes later and we are getting called for a reported structure fire... Get on scene, fire is small in the attic, get it knocked down with only a fire extinguisher, and minimal damage to the attic and area around the wiring.
Tell the lady NOT to turn the breaker back on and to call an electrician to do repairs, What the hell happens... 20 minutes later we are being called BACK OUT because she fucking did the unthinkable and turned it BACK ON... This time over half the attic sustained fire damage, heavy water damage to the interior of the home as well as holes in her ceiling, and she had the damn nerve to yell at us for tearing up her ceiling and causing the water damage.....
Oh man..people are something else. That's crazy that she turned the breaker back on after you left.smh.
Should have just let it burn
0:00 did i notice the dog licking faces clip?

Just ONE reasons so many men gave up on marriage!
Oh my, the fuse pulsing looks fantastic. Can clearly see the 60 hz.
I though so too!!!
Could be an idea to review the video, I would expect 120 Hz as in +150v, 0v, -150v, 0v each cycle giving two peaks. Still neat to see!
looks like that i feel in my dick when i cum. oh im sorry for my joke.
@@WarpedPerception what about film a old school light bulb glowing under 60Hz? it Maybe pulsing like fuse!
@@WarpedPerception This was the most amazing part of this video, seeing that red pulse in the fuse while it was heating, imagining the sine wave of current.
Awesome video!! Thanks for all the time and effort you put into to these!!
Thanks Todd, also the racing guys were asking me about if you were going to do the oil test soon? Not sure if you want me to say which one here
Circuit breaking time should be counted from short circuit to Extinction of Arc/ionized air. From the video I feel like fuse started circuit breaking first. But Arc extinction was faster in circuit breaker.
Anyway breakers are intentionally delayed from fast operation even in the event of a short circuit too. The time of operation really depends on it's class (B/C/D) and severity of short circuit. The idea of inverse time delay is to prevent tripping of circuit when a current hungry device is started( desktop smps pulls 10 to 12 times it's rated current during starting)
Glad I scrolled and found this comment before commenting essentially the same thing.
Generally speaking, fuses are for protecting devices, while circuit breakers' primary function are to protect the downstream wiring to the device.
Motors and transformers can pull anywhere from five to eight to 10 times Full Load Amps for a fraction of a second to a couple seconds , and you want a much longer time delay before circuit interruption for stuff like that. Those are known as "inductive loads" and take the C-curve breaker, for moderately high inrush current or D-curve breaker for higher inrush circuits.
Many circuit breakers don't just rely on the thermal increase to operate the mechanism, they have a magnetic component as well. These are known, oddly enough, as thermal-magnetic circuit breakers - or therm-mags.
Where kids these days get the names for stuff, I just don't know...
If you have a device that is hella sensitive to even short term over current situations - a lot of solid state stuff can be - you want it fed from the lowest curve breaker you can get, depending on what other stuff is on the circuit, but you want to also add in some fast blow fuses just upstream of it.
The fuse in the video was a stand Time Delay fuse used where breakers are typically used today - in a fuse box, instead of a current situation where fuses are indicated over breakers.
If the video had compared a fast blow fuse to a standard HACR breaker, there would have been no doubt which blew first.
They are both circuit interruption devices, but other than that, totally different.
Just like if the video had compared a Red Delicious apple to a lemon, there would be no doubt which was more yellow.
They are both fruits, but other than that, totally different.
All in all, a very good video. It gets people interested in this kind of stuff and may spark a little more investigation and learning on their part.
If so, I would recommend going to the website of Siemens and looking up their free online course on circuit breakers, their construction, operation, rating, etc. When I did it a few years ago, it was free to do the course, but it cost a few dollars to get your certification that you had taken it.
It of course goes into some serious depth on circuit breakers, but also gives a pretty good bit of info on fuses as for comparison and case-by-case prescription necessities.
The test needs to be repeated. The Breaker just happened to open at the zero crossing, so it didn't draw an arc for the entire half cycle of the AC, like the fuse did. If the breaker opened at a peak, you would have seen an arc, just like with the heater demonstration.
Yeah definitely had breakers trip when powering on my desktop PC in the past, always wondered why it only happened when powering on (and only occasionally) but obviously they must pull more current briefly during startup as you said.
If its faster for curcuit breaker, y do cars have none. It is much more time consuming to replace wires in cars than walls. If it is faster then y are car makers still using fuses? Double edged question for car makers, lol.
@@jeremybob18 because circuit breaker for Direct Current is hugely expensive and such a efficient protection is not required in case of a car. at the same time fuses are cheap.
That necklace needs a show of its own lol
I came to the comments just to see comments about the necklace... Come on WP you're not 15. I seriously hope the necklace was a joke....
Mr T starter kit!
Should have shorted the circuit with the necklace
@@mute8s hey easy there pal! I learned that one from my chiropractor back when I wore a gold chain necklace. He said removed that Mr. T starter kit .....that old bass turd!! Of course unfortunately as you have so aptly noted, I knew exactly what he meant. So you old fool ha ha to you too! Of course in a friendly and jovial manner.
@@mute8s It was 100% Joke, the whole outfit was actually, my neighbour threw out the necklace and she only wore it once, she works at top shop, I was like oh thats different, she said you should wear it and I was like "ok I will" and I did...lol. but yeah I was just messing around.
The plasma you're seeing from the wire spark isn't the air burning, it's the vaporization of the copper wire strands that are attempting to handle the short circuit current.
The other give away is the green color, which is ionized copper.
I was going to look into that but I wanted to make it more dramatic! thank you for the info !
@@WarpedPerception There's and entire codebook about protection of electricians from the phenomena. Its the biggest risk in the electrical field. NFPA 70E. at 120 you're pretty safe unless you do it right on your skin, but when you get into three phase it can create fireballs of copper and heat that will leave you in the hospital, sometimes for months, or even death. before you move up to higher amperages or voltages or move from single phase to three phase PLEASE consider contacting someone that can help you do this without being a human guinea pig.
@@t0cableguy ooohh green ball lightning... can we, pleeeease?? does the three-phase component make it to where it spins and gyroscopically stabilizes the lil slice of hell somehow??
i thought copper turns green due to rust, not ionization?
or is rust just ionization in metals?
You have the gangsta scientist outfit
lol....exactly
Circuit breakers and fuses both come in slow blow and fast blow variants. Fyi
Ok so we're not gonna talk about the alligators in the room? Omg bro 😂
he is funny like my wife, yep
Some people frown upon fuses when they actually can be superior to a breaker as there is no mechanical parts to fail and cause a failure to interrupt the circuit. Also depending on the construction of the fuse there are ones that can interrupt fault currents of up to 200,000 Amps and above, without problems while breakers with high interrupting ratings will discharge hot particles and gasses from the interruption of a high fault current and its resulting arc.
It's not uncommon to find a fuse protecting a breaker in some systems, acting as a current limiter of sorts.
That's a great point, and probably the reason that to this day fuses are still used in a lot of applications, funny enough I was just thinking about that the other day, how is changing some really big fuses on a 480-volt main panel for some big motors that blew, I literally asked myself why do they still use fuses, that's probably why
@@WarpedPerception Many reasons... Size is another, price as well...
We have a mix of both at the hospital I work at, a lot of the distribution are big air breakers, branch circuits are molded case breakers but the motor control centers and combination starters generally have tiny "J" fuses within although there are a few with a breaker instead.
Another benefit of a fuse is the fact after it operates especially after a severe fault you replace the entire device. A breaker WILL suffer damage after breaking short circuit current and can only do so a few times before its contacts and associated parts are in need of renewal or the entire breaker replaced... ($$$)...
Between you I and the fence post if I had to be in the vicinity of either a breaker or a fuse interrupting a fault I'd rather be where the fuses are...less chance of things going bad if they have a high enough interrupting rating, although I once did have a pair of glass plug fuses like what you used in your demonstration explode within a switch once.. my fault 🤣
Most underrated channel. Great job!
Fun video. Fuses and breakers both have their rolls… where a breaker could fail, a fuse would not.
"don't try at home"
I gonna try that at school
When I was young, my friend tried put the small light bulb (For battery) into the power cord in the classroom. The result is, the whole floor breaker trips. The interesting thing is, the floor breaker trips earlier than the classroom's. (My country voltage is 220V)
Damn☠️
When you connected the wires, that was not just air plasma. Copper evaporated and ignited. You can see the green flame and sparkles.
Use a fuse with high current example with a welding machine
great idea, that may look different for sure!.
If he's making another video on this, I think that is a great idea. It will tell what blows first since the other one will be turned off and not blow. Also it would be nice to have the short circuit further away from the breakers so we could see the trip process more clearly. Only problem would be telling when the actual short began. Aybe short with a mouse trap that also pushes a button and lights a dim led in the breaker frame?
That was really cool... It gives you a good understanding of both.
Pretty cool, it was definitely interesting seeing both the fuse blow and circuit breaker trip in slow motion!
wearing those super cool goggles you look like vin diesel from pitch black🔥
You dig up a doctor, and you pay him 20 menthol Kools to do a surgical shine job on your eyeballs.
Bro I have to say you seem like a really nice dude. It’s the vibe you have, the way you talk and the fact you respond to almost every comment. Love the necklace you’re wearing here btw!
Ive been subscribed to you for years now and like people tend to talk shit and hate on you but dude your legit genuine af its deffinetly nice to keep doing your thing man! 💪🏽💪🏽💪🏽
Thanks ... I know. And now I'm going to start bringing everything to you to finally so I feel people may even talk more stuff.. we'll see I guess lbvs
This is stunning
With that outfit you can shoot a super white rap video
haha, love the necklace. I remember your show on Discovery, was very good...wish it was still around. Enjoying your UA-cam channel none the less. Thank you!
Wonderful stuff. Slow motion footage never ceases to amaze me. It not only looks amazing but it reveals so much information that our eyes miss completely. I also really enjoy your enthusiasm for all of your experiments. It makes learning from your footage not only captivating but it is also a little addictive. Thank you for doing all that you do Brother, don't go changing. God bless you and your lovely family, from the UK.
You should check out beyond the press channel. They just made a setup of 72 high-speed cameras. Amazing footage!!!!
At 1:16 when you flicked the switch my TV started freaking out lol
Really awesome video! I didn't get this notification. I just noticed from ur newest upload from today or yesterday! Very cool idea! Lmao as if were both matts and both loosing weight and lookin better! Hahahahahaha! You should show every1 the inside of an E chip. The lil rainbow square in the window. With a microscope! It looks like a lil city of curcuitry! Its really neet!
Thanks for the very cool high speed video !
You should monitor the temperature of the wire, smaller temperature variation would be the winner !
The necklace would get pawn stars episode of it's own. Nice Slow Motion as always!! :)
Thank you so much. I’ve always wanted to know which one is faster
Cool vid, a good practical test. Thanks for explaining how the subscribed "Bell" works, i finally got it! :)
I have an idea for an Awesome vid with your high speed camera!
Thank You and your welcome !, im glad it helped, i also didnt know about the function of the bell as the just recently changed it. whats the idea!? you want to email it of DM ?
The copper metal vapor is what was burning, along with a small trace of drawing oil used to draw the wire through its sizing dies during initial manufacture.
awesome test great job!!!!!!!!!!!!!!!!!
Thank You!
This one showed up in my recommendations.
I dont know if someone has already mentioned it, but unless you are using an HRC (high rupturing capacity) fuse circuit breakers are used because they have a higher fault current breaking capacity than a standard fuse. For example a standard C16 6KA MCB is capable of breaking 6000A fault current, and I'm referring to prospective fault current and not the tripping current for those that are not withing the electrical trade, whereas a porcelain fuse has about 1KA. If fault current is high enough a standard fuse can actually continue to conduct after blowing by tracking through the vaporized copper splatter in the fuse housing. This is mainly true for the porcelain rewirable fues, which is why in NZ if you are modifying a household circuit you are required to upgrade the circuit protection to a MCB if it's still using a rewirable fuse
Pretty cool to see both but the fuse looked spectacular. I liked the shot where there were lingering "stars" bouncing around inside the window!
I agree! THANK YOU
Way cool
dope chain man
What bout open air fuses, like many mini fuses now? Do they blow faster than the sealed fuses shown?
The difference in time between the fuse and circuit breaker could literally be down to the electrical frequency or hertz at the speeds you're filming at but a very interesting test and I'm surprised that the circuit breaker was basically identical.
If you ever get a chance to do this again, it would be cool to see how quick Low Peak fuses interrupt the circuit. They are not see thru as the old style but they are newer technology and are designed to interrupt in 1/4 cycle. Designed to minimize Arc Flash!
I don't know if we just have different fuses here in Sweden, but our old style fuses are made of crockery with sand inside. The sand allows for heat to spread from the wire inside when under load. Anyways, the type of fuse you used was way easier to see and understand for this video. :)
For precise timing you could connect them in series! It is not easy to tell exactly when the short circuit started only from the sparks.
There is just one problem with the test.
You do not have control over where in the mains cycle the short happened,
so based on timing, the fuse would have a different breaking the current job.
Take 60 Hz, the voltage is zero 120 times per secound.
The fuse is probably using the zero current period to break the circuit, so the breaking time depends on how far from the zero-period the short happened.
Basically, you would have to rerun the test many times, or use a automated (possibly eletronic) shorting jig to deal with the variations.
There is also the DC case, where it's not given to break the current!
For your own safety sake, just use a mains switch of a higher current rating to do the short.
very true and a great point, however in both cases at 60hz neither of these devices is capable of tripping in only one voltage cycle.
You just gave "blew a fuse" a whole new meaning. Pretty impressive.....cool!!
Thanks
Very nice. I Liked the 60Hz pulsing especially. ⚡⚡😎
I also thought that was cool
@@WarpedPerception Ya absolutely 😀
Pretty cool.
Fuse or wall breaker...
Any of that is important. Fuse have to be installed in situations that after a short circuit a professional have to pay attention and discovering the real cause of the problem. Wall breaker for example can be installed in places that current get over like micro ovens and some heaters when the situation at all can be solved easily.
Simple test to see which ones the circuit first put the fuse and breaker in series and put them in a short circuit or slow overload condition and see which one open the circuit first
I can't wait for our turbo engine :D
You should do this same test with some old 1970s Federal Pacific or Zinsco breakers. They are known for being sub-par and they would be an interesting comparison to a modern circuit breaker.
Need an oscilloscope on a current transformer or shunt to record the current interrupting time. The fuse may have broken the element but from the video, it is obvious it has not broken the current flow first in the short circuit test. Industry rates industrial current protection circuits in the number of cycles the fault current flows.
Great point but my goal wasn't to influence anybody's decision on whether to use fuses or circuit breakers, it was just too give you a visual representation to make your own judgment.
Fuses are usually very fast compared with RCD's and circuit breakers
It depends on the fuse. I don't know if you have different ones but we have fast and slow fuses
Yes but I thought it was a pretty equal comparison, if I use a fast blow fuse, that would not be equal because the circuit breaker is a Slow blow fuse.
I think that with the test between the 2 options, we have higher currents on circuit breaker than the fuse option. With this behavior the fuse option is more safe for our devices but also for the cables.
Watching this sitting in Europe is quite funny, I could run this setup multiple times in every room and all it would do is make it warm.
What gets warm? The wire? Something is wrong if a short doesn’t trip the circuit.
He is talking about euro voltage and that they can run more power because 220v requires less amperage
Cranky Fox Gotcha. Maybe his house has 20amp circuits for bedroom outlets too. I’m still curious as to what is warm to the touch?
@@TKO593 In UK household socket/outlet circuits (230V) are normally a ring, protected by 30 amp breakers.
@@TKO593 the toaster is warm
Don't forget to test a GFCI outlet on high-speed.
Something that I would love to have is a self-resetting circuit breaker, including Surge Protection and GFCI.
Which one can carry more controlled overcurrent until tripping/burning?
Hi. Thanks a lot for the awesome video once again.
I am in an intensive training of HVAC:
Could you please make similar videos on
RCD (residual current device)
MOTOR PROTECTION SWITCH
Motor Protection Relay
I would always remain thankful to you.
There is also a difference in responsetime at which moment during the 60Hz cycle sine wave you make the short. If you short circuit the wires near the zero point, the voltage/current is near zero, so it takes time before the current has raised enough to reach the tripcurrent. When you short the wires when the 60Hz cycle is at the peak of the sine wave, the responsetime will be much faster.
For good comparisons, you have to repeat each test at least 5 times.
Assuming you're not using a slow-blow CB, but your fuse is slow-blow, the test doesn't answer which blows faster because the fuse's time base is skewed. The pulsing glow of the fuse link was cool though!
You look like shoenice, awesome videos.
That last fuse is a dual mode... The dull silver blob in the middle is a low temp solder that melts when longer but lower steady state overloads are present. It can't react to the sudden increase in current for a dead short however, which is what the thinner links on either side of it are for. One way or the other... Either way too much period or uncomfortably high current over a longer period of time, it goes.
Breakers use thermal for the delayed reaction and magnetic for instant for the same reason. Yours does not have the magnetic for the immediate and relies only on the fast heating of the bimetal. This is why the fuse is faster. If you had a magnetic type breaker, it would beat the fuse hands down for response time on a dead short.
4:50 the air became ionized. The plasma arc unleashes UV light, as we see the black area, the camera's sensor cannot handle it.
Your first test was an overload condition, a very safe test, exceeding the maximum ampacity and reaching the end goal. The second test - while I'm keeping in mind you were making a point of speed - was just amazing. The only reason the breaker and fuse achieved their goal, was due to the unlimited current carrying capacity of the plasma arc.
I too have witnessed the dragon, although unintentionally. I switched off an old circuit breaker, which probably had conductive dust inside, and it produced an arc flash. My saving grace was the 60A breaker at the main panel.
gread video, BUT, where are the supra and turbo briggs?
can't wait for it bro, it'll be sick :D :D :D
Working on it now !!!
In series the fuse will always protect the cct breaker. wife liked it too
I'd be curious to know if the fuse plasma conducted longer than the circuit breaker's lag in disconnecting
for that u need next level brain
Can you toss in a GFCI breaker?
Idea for next video ; a chain of firecrackers, in slow mo
I thought you were gonna wire them both in series with each other and test which one blows faster. The high speed camera tells it all. I am an electrician and deal with all sorts of different electrical current protection on a daily basis and can tell you every time fuses blow faster. Next is Square D's older QO breakers which are in my book top of the line. The new stuff can be counterfeit and junk. Next is Square D's Homeline series. GE's are on the bottom of my list because i've arched out just about every one of them and find GE's interrupt a lot slower leaving more damage to the wiring and devices connected. Even had one instances where sparks flew out of a GE panel and caused arch flash damage to the breaker itself. One thing I do like about GE panels themselves is the fact they use a better alloy copper buss which is better quality in some of their powermark gold series. I know you probably cant compare whos better due to lawsuits and such but would be a nice video to see which breaker trips faster. There are other manufacturers like Siemens, Bryant, etc but all use the same type of tripping mechanisms that GE uses by the way they trip but I always find older Square D QO's to be the best in my opinion just by how fast they trip on a short circuit situation along with having a lower arch flash causing minimal damage to the device or wire.
Can you set up a phase to phase short on slow mo?
Yeah really that is much cooler than just 120v pop.
Very cool. Why does everyone update to breakers? I very rarely blow a fuse. It would not be cost effective to switch to breakers for me. I was thinking about upgrading the house because everyone says breakers are so much better. The most important thing is how quick it blows. You’ve proved that they are pretty equal with the fuse edging ahead in the one test. Thanks for saving me cash!!!
Great vid. A fuse will always blow, usually within the first quarter wave of the short. Breakers if they are not cycled on/off after many years, can weld their contacts closed and not operate (trip) when needed. It can take several cycles for a breaker to trip. To test the actual trip time, test for when the current stops in the test circuit not the flash. Best to use a scope, a meter is not fast enough. The scope trace would look awesome on the slow-mo
Interesting. I have a habit of cycling my breakers in my house atleast once a year. Sounds like it’s a good thing to do.
@@austinaubinoe Thanks it is just one of the little issues I have seen over my 35 years of electrical maintenance. Some of the breaker panels at my work haven't been touched in 20 or 30 years
A more elegant way to answer your question is to put the fuse and the breaker in series, and see which one blows/trips. (The first to blow/trip is the only one to blow/trip.)
Love the videos but could’t help but think, You’ve got to think of the frequency point of when it blows, each test the circuit breaker or fuse could be breaking at different times in the sine wave resulting in different power levels at breaking point,so this test is not 100% accurate. If the fuse was connected around the peak of the sine wave it would have the most power running though at that point hence quicker time, the circuit breaker could be starting from zero and taking a longer time to get to peak power and they have a mechanism that takes time to activate but has a strong hair line trigger to disconnect as fast as possible.
DC wouldn’t have this problem, or you need some way of working out at which point in the sine wave the circuit blows, and calculate the power at that point or start from a zero point in the sine wave, can be difficult to do.
You have a great point, and that's very very true. However on the fun side of things I was just fulfilling the viewer request and seeing what was going to happen. at the very least it gave people a good idea on how each device works differently but accomplishes the same task. Thanks !!
Warped Perception no problem! Of corse it is all for fun :) just felt i needed to point my thoughts out :)
You have alternate current in 60Hz, it means you have half cycle every 8.3ms. 14 frames are 4.6 ms. Your hand is so slow compared to oscillation, we can assume the spark started at some voltage peak. In both cases you got arc extinction in aproxatelly 1/4 of period, only during the falling tension from Vmax to zero (or raising from -Vmax to zero). I would say both blow at the slowest possible time, because they allow current flow in one direction, but not in the other one, and the arc was extincted because zero tension (sorry I'm not English native speaker).
To make better measurement I would recommend to use direct current.
Good Idea! I just used ac as this is what these normally handle
7:01 - Realize, of course, that the Available Fault Current in a residential setting is anywhere from 10 thousand amps to 25 thousand amps. There's a lot of energy in that amount of current. Under those conditions the metal inside a 15 amp fuse doesn't stand a chance!
Question. Someone I know wired an outlet Hot/Gold Hot/Silver Neutral/Gold Neutral Silver. I was called in and wired it correctly Hot/gold Hot/Gold Neutral/Silver Neutral/Silver. No juice? Could the previous mistake take out another outlet? Maybe the knuckle on the fuse pnael?
can you try this with bouth Fuses in line ? sorry for bad english
Fuse is a one time use vs circuit breaker which is reusable
I love how the fading flames at 4:53 have a greenish glow. I wonder if that’s from copper atoms glowing green, or perhaps it’s just a video artifact because of the very bright light a moment before.
I was wondering about the colors as well. It's sort of a crude spectroscopy (sp?)
The human eye sees the arc from a copper short as a distinctive shade of green... don't ask how I know this.
would have been interesting to have the comparison with the circuit breaker and the fuse mounted in series with one another for both the tests. That way you'd see if one or the other would break the curcuit consistantly faster/slower than the other... plus you wouldn't have the uncertainty of when during the phase the short was made. Both would experience the excact same scenario.
True but I would need double the current
@@WarpedPerception - That would be true if I'd sugested mounting them in parallel ;)
In series of one another the current remains the same. The same current runs through one then the other. This way you ensure both the breaker and the fuse are handling the excact same load conditions. :)
The long story :D
There are a couple of interesting points to draw from this test.
For overload:
If the curcuit breaker cuts off first, will the gradual heating of the fuse have made it weaker? It seemed like if you were to cut the power a couple of pulses before the fuse failed that enough material had left the lead to actually make it weaker.
For the short curcuit:
The fuse will most likely fail no matter what. But will it fail fast enough for the curcuit breaker not to disconnect?
Lorenz force is what blows the fuse apart like that. Creates an opposing magnetic field in that pulse that pushed the parts apart.
That's it !!! It was on the tip of my tongue oh, but that's what it's called.
I think it would be cool to see electrical arcing in an aquarium that has a mixture of clear oil and water - may actually make for some really neat arcing, especially if you get creative with things you can dissolve in the water, or agitate the mixture to get cool shapes out of it. Probably more artistic than informative, but who knows.
As much as a more complex switch initiating the hard short would be cool for getting more precise data, I think the difference would probably be about the same, and also affected by just how much effective inrush (impedance gated) the wiring and switch are in terms of heat transfter into the resistive bridge on the fuse, which again wouldn't tell us as much. I think there are advantages of fuses in that they will withstand inrush currents at small scales a little bit better, but you spelled out why modern circuit breakers are the standard.
what music is 2:10? have you used it in other videos?
How about fuse-based circuit breakers? I use these in my home, in place of regular fuses, since they don't necessitate a new fuse each time. Perhaps a future video idea?
Could you send me a link to an example? I don't think I've ever seen that before.
I'm an electrician. the "plasma" you described is exactly that. plasma. the oxygen is burning due to the heat. we call this an "ARC FLASH" and at high voltages and high amperage (current) the arc flash can become so bright, it can cause blindness. the plasma generated can exceed the surface temperature of the sun. we have to wear special glasses to protect against arc flash faults in those cases because seeing an arc flash at 50 feet away is bright, but when you're only a few feet away the risk of permanent damage to the retina is certainly there to cause irreversible damage and even complete blindness. the most common way to see an arc flash is when a pot transformer on a telephone pole fails. that blue/green/purplish light that lights up the sky is an arc flash due to a fault in the electrical system. if you are ever close to these incidents, please i understand it looks cool and all that, but do not stare directly into the arc, as ive stated before, this can cause serious damage to your vision.

PEACE AND LOVE
Great points ! Thanks for the comment and the info.
Hi There,
Hope you can help me with this question:
How can I Protect Electronic Equipment from a near by Lightbing Strike, if the lightning hits the power lines and travels thru the lines?
Can a FUSE Protect the Equipment from the high current coming in?
And what kind of fuse should I Install? Fast Acting Fuse or Slow Blow Fuse?
Thanks for your help.
For this, you need to use SPD
Cool demo. Definitely the fuse first. Does the difference in time for survival in a hot tub/hairdryer scenario matter? No, but what about a GFI for a third option? Gold, Silver, Bronze.👍
Thanks!, I totally have the GFCI on my list!
Your talking about which is faster but your using a time delayed fuse
Yesterday I blown the fuse (Same model in the video.) due my old Microwave oven doing weird, everything in the socket turns black.
Ok so now if you wrap one of the wires around say idk some high silicon extra mild eye-ron metal a buncha times, like oh eleventeen or so wraps.. would that blow the bridgemetal in the fuse with more gusto? Or would it just take a bit longer, while saturating, then proceed sorta as it had using this unloaded state short circuit video as a control ?
Good question
@@WarpedPerception there's power in the flux.. but only when it collapses i think. but in comparison with capacitors? idk, its where im at in electricity as far as getting a sense of. Magnetically, which induces electrons to flow, or emf maybe, vs storing them on the plates? or the same emf as a discrepancy? maybe thats more like leyden jar storing the tension.... wonder, devise, spearmint, and show us maybe??
Please connect the MCB and the fuse in series and then test which one breaks the circuit faster.
IMHO it seems the fuse is only 2 frames faster when counting the current flowing through plasma inside fuse. I think more accurate would be to measure the time of current flow using oscilloscope. But otherwise it's a great video showing how that two protection elements work. Could you also make a recording of residual-current device (or residual-current circuit breaker) switching?
Try a fast acting fuse. It will definitely blow faster then the time delay during overload but in not sure about a dead short.
How about a gfci outlet or breaker?
I have been in the electrical industry for 40 years.. both have their place but, as a general rule, fuses outperform breakers in life safety performance. They can be designed to trip more quickly (less than one cycle) and they have a larger current interrupt ratings. Breakers are better at seeing and reacting to waveform disturbances as well as their overload function. Your typical typical fuse can withstand a short of 200,000 amps but they typical breaker is rated at 10,000 A...
Im an electrical lineman....very cool....i think a fused high voltage cutout blowing would be pretty cool too...
Thank you
In this specific case when comparing them you need to measure the current to see the actual pattern. But you should have put in a description of the parts in the specific circuit breaker because not all of them are alike.
my fuse: diy wire😁
just use ps with current limiting to determine the amps that can it pass through without burning
You can connect both the circuit breaker and the fuse in series.
