480 volt 3-phase Arc Flash Demonstration

[kipkay211]

Man grabs wire, ARC FLASH, ding, dinner's ready. XD

[teslapower220]

Lol.... the bell...

[seansy59]

Cool! I'll buy it.........

[jake3085]

How many amps is that?

[markhodgson600]

ding dinners ready lol



[iichhaald]

fuse says good bye xD

[simonspaz]

Ding fries are done.

[jlo13800]

[480arcflash]

this was a demonstration , it was simulated at a sub station to show lineman the severity of arc flashes

[cgrasser7075861624]

Only an idiot would wire this up, but there are a whole bunch out there. I am with Jesse Ventura on making drugs legal; in order to get rid of more idiots. If he runs for President, he has my vote.

[jake3085]

is that like a 3 phase line that u would find in a work shop

[TheSpike3000]

@jake3085 What, are you going to do this in a work shop? BOOM BOOM BOOM BO BOOM BO BO BOOM! lol

[jake3085]

@TheSpike3000 lol

[480arcflash]

Brown orange yellow, love it ! Nothing like the thrill of working in a 480 cabinet,

[480arcflash]

Wow

[Retrograyed]

The ding was the best part by far, "Ding, everyones livers are cooked."

[forwardbias]

This is why noobs should not play with triple phase unless you know what the eff you are doing. Imagine you making a phase to phase short accidently, working on something like that hot, your face right inside the cabinet, would be like a grenade exploding in your face. Likely lose both eyes, and have serious burns and scars to the face if you had no protective equipment on. If possible, dont work on stuff energized. Saw a 480 box once, had a warning about 44,000A short arc flash current, OMG!

[syncman2x]

@forwardbias And This is why I never work in the industrial trades. Being in an office is not Lazy; would you want some kid you accused of being lazy and indolent working on Triple-Phase? shit! I would have an electrical engineer supervising if I were only using a petrol generator with Triple-Phase !

Go ahead, call me lazy ducker, one more time.

[red6608]

I think I should start locking out pannels when I'm working on them? Na one good one the wife will be a rich lady!!

[phazonxl]

Oven of the future.

[Snoep76239]

Next experiment: Instead of wires, use tins of Jiffy Pop!!

[Snoep76239]

That's why you use insulating (better than just insulated) tools when working in a live panel. Drop a spanner and it ruins your day.

[djfreebey]

holy shit that mad

[simpox94]

it's fake, they are just burning up a 1000 popcorns -.-

[karbonphiber]

doesn't look that bad...the wooden box is still in tact

[smokescreenninjato]

@karbonphiber ya but if you were in front of it your skin would be burned due to arc flash and you would have molten copper sprayed on you

[burn19ballz]

no wait screw that idea,make this a new form of death penalty execution.XD

[burn19ballz]

i need a deep fryer like that! DING! max! your chicken is done!

[PeloquinforSenator]

Yes , I have been developing and Arc Flash Program and in this process I have retained a new respect for 480 volts and above as weel as 50volts it only takes .06amps to killyou...WOW! imagine the power.......this is a good example of that. Dr Paul J

[freerocker101]

@PeloquinforSenator yeah but dosen't a person (depending on many factors) have an average resistence of like 16k to 20k ohms

[imfree707]

People need to realize what happens in an arc flash like this one. A thin wire explodes at 120V, but that voltage will not produce plasma and runaway fault current. At 480V and higher, the initial small arc explosion produces a plasma that conducts hundreds, even thousands of times as much current, between those bus bars, than the original shorting wire or object! That massive moving short consumes large amounts of bus bar, throwing metal particles and vapor into tshe air!

[Nivicoman]

@imfree707 Yeah 240V or below is pretty benign I've never seen arc flash occur below 380V or so. 240V or less just makes lots of yellow sparks and smoke no plasma and runaway fault current as you describe.

Now 4160 or higher........

[kymbolino]

@Nivicoman Arc flash has more to do with short circuit fault current, and can occur at voltages as low as 1V. The high voltage of an arc flash comes from the energy stored in the line as inductance, not it's nominal line voltage. It's directly proportional to the rate of change of current flow. The faster you break the current, the greater the voltage.

Typically 240V circuits is generally so far downstream in a network that it's fault current is small. But not always!

[pmgodfrey]

Instant bag of popcorn.

[rockerzac99]

@pmgodfrey Yesh.

[intheshitter]

That was hard core

[FriedGames]

*DING* Pizza is ready!

[sbd45acp]

BOOOM! Ding! Stick a fork in him.... he's DONE!!

[punder30]

Damn I was searching for cooking a turkey in a microwave..how did i get this?

[Paxmax]

@punder30 you threads the wire through turkey, hit the switch and by the time you can say DING! it is DONE!

[Chaffie74]

i've seen that happen in a motor control panel, but not as big as this. oO

[sustayne]

Love the little bell at the end. It's the doorbell at heaven's front door.

[DarkZero812]

ding...

...sorry but the order you have requested got a little crispy

lol

[Paxmax]

Standing close to that it would certainly sting... Copper in gas form is hot.

[dvu90]

This wouldn't happen if there's a fuse, say 200 amp?

[fclearchannel]

@dvu90 yes it would, it can happen at any amperage even a normal house circuit of 15 or 20 amps it's just on a smaller scale

[67tr876]

@fclearchannel It just happen to me last night but on 120 you get a nice pop.

[twn5858]

Scares the shit out of me!!! And I have to go work on a 480/277 panel.

[CornishMorgan]

@twn5858 work live, you'll be alright :P

[Nivicoman]

@twn5858 I know. I've seen it at work where 480 flashed over between phases on an input breaker of a DC supply under test because of humidity and the fact that the phase lugs were too close together. The salesman (started as a tech) was lucky our lines were so soft and it still tripped the 1000 Amp breaker at our service entrance. He only had some small molten copper splashes on his glasses and stunned a little. Then there's 4160/2400, 13.2KV/7200 on up. Fuck that 480 is plenty enough for me.

[mrfirewolf]

zap zap zap zot zot zap ding! fries are done!! lol

[evanlistokin]

DING microwaves done

[dvu90]

If there's a 100A fuse, would the result be the same?

[LordVoltRod2c]

First time I saw this it brought back fond memories of my babysitter when she would say dinner time. I ate the food anyway becouse she was nice and I did not want her to feel like a failure. Besides I was so much of a friggen brat I figgured telling her this tasts like s*** would have destroyed her for life.

[Visionikz03]

popcorn is done!!!!

[TheGodParticle]

That reminds me of fallout 3 ding when you do a good kill.

[andrewontiveros]

ah hah and this is where babies come from !

[thdmtr]

lmao was that an arc or a grenade??? rofl

[djkukucek]

yea DING and its done dumbass..

[pauloz386]

So it's a bad idea to short all three phases with thin wire, what about thick wire?

[HWGuyEG]

3 millisecond pop tarts.

[XGQ1P0]

Nice demo, too bad they had to fake it to make it so dramatic. Try to find out some real statistics about arc flash, good luck. OSHA only adds to the data base if there is a fatality or three people get sent to the hospital. Otherwise no data! The Bureau of Labor Statistics won't even reply to a request for information about voltages involved in actual arc flash incidents. NEC70E is all about the money involved in selling books, books to explain the books, and seminars to explain the books.

[GrimlyKK]

@XGQ1P0

Jeeez, you really are a dumbass bastard.

[randomvideowatcher]

Tim Allen modified that microwave.

[visionisscary]

SEE you can see electricity - and smell it too

[randomvideowatcher]

Someone opened up the magic smoke and spark packets.

[08Kutt]

wow! likes my microwave oven! DING

[VicariousReality7]

Holy shit, the smoke

[GraysonFox]

Thanks guys ;) The "Ding" sound really just made my day.

[HappyDiscoDeath]

BUZZZUZZZZZUUZZZZZZ *DING*

[carl0071]

That's one hell of a quick microwave :-D

[EMMAWONDERLAND1]

BLAST OUT!!! Electric explosion of failures! How bad isn't.

[HoneycombAgent]

BRRRZZZZZZTTTT!!!

*ding* Oh! Sounds like my noodles are ready! Just as soon as I change the fuses...

[Mas7erChief117]

lmao the little bell its like dinners ready!!

[140leon]

who order steel fries???

[normellow]

That bell sound means dinners ready !!!

[ubuntupokemoninc]

i've heard people say that electricity hates them, its because they form a reputation like this!!!

[ELITEBK5876]

True power....NOW ENVY!!!!

[rcfp2006]

love the ding, like it's saying "meals ready"

[BFMVpwnage5168]

okay that was fucking awesome

[towert7]

The ding rocks.

[btuck62]

What happen when you mash dis button?

[Gulftango11]

Would just tingle a little

[sinborn41214]

this my friends is why you don't wrap a fuse with aluminum foil

[Ironbirdx]

like a high speed microwave...

brrrr..DING!

a hole 25 person dinner heated in just a second :D

[thelightguy1]

Always! Use the top possible current on a multimeter! Or else you will get a similar reaction.

[cheetawolf]

FART!!! ding. Lol

[BlackSkies1944]

I am so roasting marshmellows, and hotdogs with that, who will join me?

[daathboot]

That's why you wear your ppe's

[PhxSt0rmz]

@daathboot

Now if only our PPE, as suggested by OSHA, could handle 35000F arcflashes. Such a painful thing if you ever get caught in one...Teacher had experiments with industrial 1000A busbar.

[simonmitchellbird]

the 'ding' at the end is the same noise a microwave makes when its done. Imagine that being a microwave

[khaozero]

@simonmitchellbird .... is it a good idea to microwave this?

[simonmitchellbird]

its always a good idea to put random things in the microwave

[allclear241]

U sure that was 480v?

[croakerchoker504]

son of a biotch!

[cmazzac]

this is what i think about everytime i am working in a 3 phase 480 panel...

[bait28]

exactly what happened to my block transformer when under service.

[skylinevq35]

I feel you man. I make panels like that almost every day. NQB'S, WEB, column panels and etc. I know what they are capable of.

[trebor121290]

And that "Ding!" means your pants are now completely soiled!

[beaman220]

No Nooo, ding means dinners done! It was a plywood microwave.

[SuperBeatnuts]

proof that electricity dosent give a fuck

[mechanicwarrior20]

@SuperBeatnuts lol kind of similar to women aye?

[MICKEYISLOWD]

@SuperBeatnuts got that right haha!!

[smiley235]

In Australia, its 230V single phase and 400V 3 phase, but ive quite often tested close to 250V and 430V. Depends how close to the transformer I guess.

[justinaurelius]

Ding! Popcorn is done!

[csengeri]

480 V? Not 380 V?

[fnaguitarplayer9]

why would it be 380? 3 phase is usually either 240 or 480.

[csengeri]

Oh sorry, you use American system.

In the European system 1 phase is 220 V, 3 phase is 380 V.

[fnaguitarplayer9]

really? i didn't know that.

[csengeri]

Btw Thanks your comment! I have just learnt more infromation about electric grids. ;)

[fnaguitarplayer9]

your welcome, and so did i. i'm in a electrician class and i'm used to workin with 480 3 phase, i seen 380 i was like what?? hahaha

[lordofthemanor67]

@csengeri European is 230V single phase and 400V three phase as per BS. 7671. 480V obtained from 1 phase 3 wire system.

[csengeri]

Thanks the information! I said 380 V because it was a while ago before they raised it to 400 V.

[markupRockers]

sounds like black metal ^^

[MushaGenesis]

Haha that's one way to build a microwave. DING! KIIIIDSS! Dinner!

[soylentgreenb]

Only if you prefer your chicken nuggets explosively assembled with a nice copper oxide crumb-coating.

[71ford]

I know it's been said already but I just love it...

DING! Dinner's Ready!

Even better in slow-mo...

Great video, crisp and clear, good frame rate. I love seeing electricity in action!

[babedibab]

lol, the ''ding'' was like the ding in a microwave...

[leebob86]

WOW... Trying to create a new super weapon or what?

[MrSparks134]

DING! FRIES ARE DONE!!!

[Gerrit22041992]

lol, i laughet loud, really a lol

[hellzone100]

@MrSparks134 LMFAO

[kennysc12]

from static how many volts is a one second shock that goes from the tip of my thumb to the bottom?

[kennysc12]

and what if i add a magnetic wire coil?

[Danielkwalsh]

The electrical Breakdown of air is about 3x10^6 V/m. So since your finger probably approached from a distance and sparked when the breakdown field reached the appropriate value, we can say that the voltage is about 80,000 Volts.

[knkyclpy]

read the intro then you ll read that the terminals were shortcircuited. don't think youre smart

[NSResponder]

Damn, electricity! You scary!

-jcr

[DonkeyFist]

Ding! Your food is done!

[postchevelle]

Haha, I was thinking the same things when I first watched this. I guess they couldn't wait for the popcorn to finish before starting the test...LOL.

[lolzinOo]

haha, quality!

[evilcore66]

dip shit this was a test at a LAB. u think some crackers sneaked into a power station and blew this shit up?! gullible dooosh

[GphilippG]

lol ich gebe eine *5*

für die explosion =)

[atethnekos]

Whoa! Is that actual German? Because it's so close to English it's almost as if it was just a different dialect.

I give a "5".

For the explosion.

Pretty much the same in English. Weird.

[TheTheo58]

Anyone notice this has to be a power sub-station? How in the hell did these people get in the untility co did not let them in! Not only was that a very dangerous thing to do, the arc flash had to fry or do serious damage to the swiches, breakers and maybe ruined transformers.

[nswsparky]

That is now why they have the OSHA Ark flash rules now Have you seen a Full Class 1 Arc flash suit?

[cacawmofucker]

watch?v=4w4h7gnc3qM

arc blast with test dummy.

[ap327145]

Ding...Chickens Ready

[Coiltec]

I am glad this could't happen with normal household current.

I (in Germany) have 3 phases; 400 volts and 63 amps which go into the house. The normal sockets are only 1 phase; 230 volts and 16 amps.

I think, in this experiment they used a few thousand amps.

[cordellgear]

arc flash can happen with 120 @ 15amps (what we have in america)

[Coiltec]

Yes, but not as strong as shown in the video. In Germany (230V 16A) there is just a loud *poof* and the end of the wire is vaporized. Then the fuse blows.

[cacawmofucker]

what you crossed (if at the socket) was a hot and a neutral. if you went to the panel and crossed all 3 phases, guaranteed you would have a much bigger bang and 3rd degree burns on your torso, arms and face and you'll probably wish you were dead if you aren't already

[CardBoardPimp420]

yeah nothing to that extreme though, shoot a federal pacific panel will trip before that happens lol

[BlackCarMafiaRidaz]

I wouldn't count on it

[artdamage0]

thats the same in australia, we have three phases going into our houses for airconditioning. 3 phase, 415V. if u short a powerpoint to earth or neutral, then there will be a brief spark, and the RCD/MCB will trip. if you short phases before you household main circuit breaker, the pole tope fuse, or underground power fuse will trip, but there will be a big bang

[wildsurfer48]

bbbbbbbbbzzzzzzzzzzzzzzzzzzzzz­zzzz!!!!!!!! ding!!!! you're terminated!!!!!

[wildsurfer48]

bzzzzzzzzzzzzzzzzz!!!DING! you've been terminated!!! lol XD

[bauditlad]

*DING* You're fucking dead.

[xXxmidgexXx]

wtf is up with the ding lol

[enyceckk101]

Ding , your dinners ready

[bubbleglass]

that scared the crap out of me

[itsCATURAY]

TZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ­ZZZZZZAP! DING!"Hey wtf did my microwave just kill s9omebody?!?!?!? Oh no wait i forgot..." *computer voice*" sLICED pOTATOS ARE FINISHED COOKING" "oh. damn that was fast."

[Electronics111]

buzzzzzzzzzzzzzzzzzzzzzzzzz ding!

[ARR016a]

cooking chicken.....bzzzzzzzzzzzzz....­.DING!!!!!  ROTFLMAOLOL

[zimtower]

Gotta love vaporized copper.

[superpimp14x]

DING FRIES ARE DONE!

[djtom74]

dingg chiken is hot

[chris507npowell]

I love the short flash. a good way to destroy junk

[brownp15]

yeah , when it happens in your face it feels like an explosion!

[ts3000]

Been there felt that.

[skodas]

ding on the end coollllllllll buzzzzzzzzzzzzzzzzz dingggggggggggg

[BenHutchinson1]

Copper oxide smoke? I didn't know copper burned. I though only some metals (magneseum,sodium, etc) could burn. I thought the smoke in this was from the wooden case burning.

[cordellgear]

the copper vaporized

[fuwafuwa9]

何を爆発させてるの？

和訳できる方お願いします（・_・）？

[superdave27656]

had that happen a couple feet from me, dumbass sheared off the plugin for a welder

[FreedoMnoSocialism]

277. 347. 480. 600. end results are the same. burn. blind. kill.

[BIGBALLS4YOU]

fuckin a

[Wolvster007]

Lol Microwave..

Yho Jack your Toast issa *SWOOOOSH* *Bing* Ready!?!

[Etrician55]

600 is a crazier voltage then that wimpy 480
