Fuse vs Circuit Breaker Which Blows Faster (Slow Motion) 

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?

@@WarpedPerception 5:36

Just ONE reasons so many men gave up on marriage!

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.

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

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.

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?

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.

lol....exactly

he is funny like my wife, yep

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☠️

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 🤣

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?

You dig up a doctor, and you pay him 20 menthol Kools to do a surgical shine job on your eyeballs.

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

You should check out beyond the press channel. They just made a setup of 72 high-speed cameras. Amazing footage!!!!

I agree! THANK YOU

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 ?

Thank You!

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

Thanks

Working on it now !!!

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 also thought that was cool

@@WarpedPerception Ya absolutely 😀

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

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.

for that u need next level brain

Yeah really that is much cooler than just 120v pop.

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.

Great points ! Thanks for the comment and the info.

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 :)

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.

For this, you need to use SPD

Thank you

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?

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??

Thanks!, I totally have the GFCI on my list!

Could you send me a link to an example? I don't think I've ever seen that before.

Good Idea! I just used ac as this is what these normally handle

Christopher Western no they are not. The amount of electrical fires causes be fuses is crazy

Older is always better in my opinion.

That's what I have heard !!!

@@boilanque Residual current circuit breaker (RCCB) is not used in place of a fuse(RCCB equivalent to ELCB or GFCI). Only MCB- Miniature Circuit Breaker should be used as replacement of fuse.

@@christopherwestern9223 I hope your electric shower never develops a fault whilst your in it, you will soon wish you had a modern protective device I can assure you

That's it !!! It was on the tip of my tongue oh, but that's what it's called.

Very nice!. Sounds like you had some loose main wires in that box!!. Lol
