I really like how the title isn't something stupid buzzfeed would put like "something you didn't know about electrical plugs"
Victor Baeza Exactly
Victor Baeza IKR
Buzfeed sucks
3rd Plug Reason is Shocking.
Victor Baeza I know right and it's straight to the point once a maybe 5sec ad depending where you live but still I'll watch a unskipable 10sec ad for this videos
I was doing some a2 homework, saw a youtube notification, now I've been on a 2-hour youtube browsing spree and was currently watching this video. Continue on with your day.
Edwin San Juan what does algebra 2 homework have to do with electricity
nothing, when I wrote that, I was working on some homework, then I was notified of this video.
beutiful
Russia Did It Lmao, I am Asian tho
Edwin San Juan Me life rn
My dad (his an electrician) has told me all my life how annoying it is to sometimes rewire houses cause most people used to be too lazy to follow the rule with H on the left and N on the right. So next time you think to stick a fork in an outlet on the right saying you wont die, think again, he said hes found more false wiring jobs than right ones. Hes also been an electrician for 30+ years.
I hate when people can't do simple things that are their job >.>
I thought the 3rd prong was for more power consuming things like vacuum cleaners, glad to know I won't be killed by any vacuum cleaners ☺
Mr. Crazy Muffins: Careful when you sleep. I hear the Vacuum Cleaners plotting against you in the corner 😂😂
UNSC INFINITY don't worry all their attack plans suck.

When the man's hand got shocked at 1:53, I jumped getting scared lol
Those lightning strikes scared me lol
Ἀχλύς especially with earphones
I got scared when the guy toched the metallic casing
Always knew it was the ground, but thanks for explaining the rest. In my experience, some metal cased electronics have faulty ground wires, and if you touch them while they are on, will give you tiny shock versus the full 120 or 240 volts. What most commonly causes this?
This is normal for computers and not dangerous but if the equipment fails it is dangerous. You should have the wire fixed. Note if you use such an equipment on an ungrounded outlet that is normal and there is nothing to worry. Just do not touch the equipment and a radiator at the same time in case of failure.
The voltage is about 115 V but the charge is not much.
who else reflexed at 1:50
John Irvin Divinagracia It wasn't exactly a jump, but from the shoulders up, I just tensed.
Technic 12 no one cares
Medo Gabr fuck off nobody likes you
Big Brother you really got me there! Nice insult idea!
Medo Gabr Don't talk to me. Nobody likes you.
in the UK you cannot access the live (hot) and neutral connections in a socket without the earth pin opening up the flaps. this means the appliance is earthed before any other connection is made.
we also rate all appliances separately with smaller fuses in the plug top, rated to the appliance.
not to mention mandatory RCD protection for every household.
You guys are way ahead of us in the West.
any one else notice he had a plug into his push mower 😂😂
Never heard of a mower that plugs in. Seems like a great way to get an extension cord caught in the blades.
you would also need an RCB just in case it happens
Same could happen with vacuum cleaners but most have plugs. Just like vacuums you keep watch of your cord.
Shadow Fan yes, the rcb detects a current difference, when you even begin to cut the cable the resistance in the live (hot) wire (I'm from the UK) would increase thus reducing the number of amps, the RCD cuts the supply before any major damage is done
Raven Bristol that's a lawn mower not a push mower.
A lawnmower with a plug
I have one with a plug, it can get really awkward
AM Productions Yeah? it's an electric mower.
Logan Cochran incorrect
AM Productions see attached
i have one of those and theres no gas emission so it's more eco friendly
1:50 Clench your butt cheeks.
starpravesh i jumped lol. 😂 I wasnt ready lol
*Fascinating ✅😀*
Standard here in Europe
Only UK and Ireland
Not in Denmark
Nikolaj Mohar it is legal standart in Denmark a lot of people just ignore it
Malaysia too
In Brunei too... with Fuse integrated within the 3-pin plug.
1:50 Had headphones. Scared the crap outta me. I was in shock.
For everyone arguing about grounds (the 3rd prong) it's pretty much the standard for all new construction world wide, but there are places where enforcement is rather lax and even in the USA there's really no requirement to upgrade existing outlets unless it's a commercial building with something else going on that needs code updates. You can pretty much find 2 prong outlets in any structure built before 1960 for most of North America, including the Caribbean islands, which seem to be running 20 - 30 years behind, code wise. Almost impossible to buy one these days unless you find an old hardware store with old stock. I would bet that Central America is in the same boat, but I have not been there personally. Heck, I don't recall seeing a GFIC outlet in any of the islands prior to about 2002, although I'm sure they install whatever is available, regardless of the wiring in the wall actually being connected to an earth ground. I suspect this is what some here mean when they say they have not seen any grounded outlets in their area. IOW, they live in an older structure that's not subject to mandatory upgrades.
the UK has the safest ones
Why is that?
+Gasper Gril watch Tom Scott.
First, the UK ones have three outlets. The top one is earth, the right bottom one is live, and the left one is neutral. The live and neutral outlets have a distinct safety feature. They have like a trapdoor or something that won't open before your earth pin is plugged in. The earth outlet has a button inside, that allows the two bottom pins get into the outlet. Also, the bottom pins have insulation on them. So if you leave it halfway out, all you can touch is the insulation of the pin.
That's the basic safety reasons. You can go watch it on Tom Scott if you want further explanation.
+Nik Ahmad Faris Nik Mohd Radzi Ok that is pretty safe but to be honest it's just todler proof I mean you most likeli you will never touch the outlet holes
But it's so sharp
Malaysia has the same type of outlets too, I've been to the UK before and seen then
Just some technical things to point out and correct.
Voltage does NOT move through you. Voltage is basically electrical potential between two points. Current is what moves through you, and it flows from higher voltage to lower voltage.
If you're holding a wire while wearing runner sole shoes, the current will not flow from the wire to ground, as the rubber stops the circuit from completing
This is why in third world countries electricians wear rubber flip flops while on the job.

Mr. Meeseeks what's your problem? Did he harm you? He was just thanking the owner of this video... Everyone can play what he/she wants lol, no need to hate.
we don't want aliens like you in earth
Here in the U.K. It's also for opening the shutters on the plug each small slot where each prong goes into is blocked by a plastic white shutter preventing you from poking at the Inside and when you plug something in the third prong opens the shutter allowing for the plug to go fully in a once remove the shutter falls back into place
Which is also why we always need an earth pin, though this has led to the widespread misconception that appliances in the UK are always earthed, when the earth isn't used any more often than in the rest of Europe, for example
Thanks third prong, I love you.
your stray capacitance to the ground does it( 1:30 ). it will only send current through you to ground if its ac. usually the lightning arresters take care of this but if you are outside and in a thunderstorm, usually no current should pass through you. Unless you get directly struck(or stand next to a tree or any tall object) and it travels to you

At least it woke me up 'couse I just get up from the bed lol
Emmanuel Aguirre Mee!
1:49 "lethally shocked" and it's one of those common shocks you get when you're wearing socks and touch a metal door knob.
Now to really confuse you, the neutral and ground are actually directly connected inside the breaker box. Another way to think of it is that the neutral wire is the "intended" or "protected" ground, and the ground connects equipment that shouldn't be energized so the electricity goes through the extra wire, not you, if it dose become energized.
In my country Malaysia we use plugs with 3 prongs and the style exactly as same as in UK. So those coming from UK to Malaysia does not need travel adaptors.
I was wondering why some don't rather than why some do. Sure it may be unnecessary, but why not take the extra step?
sometimes there is nothing to ground, because of good insulation
Your pfp sauce
This has been taught in our school. So easy to understand. It is only for revision. Great!
1:51 that made me jump so high I'm glad I didn't hit the celing!
In Britain adapters are double insulater which means it has no grounding but still have the ground prong
the ground plug now acts mostly as a way to create a 3 safety measurement for the flaps over the top to holes so you cant put something in them with out that ground prong in its slot.
If AC flows both ways, aren't both wires the hot wire? Also, great vid.
No, the hot wire has voltage relative to ground that switches (in Europe) between -325 V and 325 V. (U.S. -170 V ...+170 V) The neutral is connected to ground.
Only in a 240V circuit
To me it always felt that the earth grounding created more problems than it solved. And the ground bonding is mainly there to fix problems introduced by earth grounding, + running extra copper. It's kinda fixing the problem that it has introduced in a first place. 90% of Russia never had grounding, no issues whatsoever.
So basically they're realising what the British designers realised a long time ago... earth those fucking plugs!!
David Birtles
They've been around forever, they just aren't mandatory in the U.S.
Grounded receptacles have been required in the US by code since 1962
I don't think you realise that there are plenty of unearthed plugs in Britain, just like the USA. The only difference being that British plugs always have 3 pins so that you don't need more than one type of socket.
Why are you trying to take pride in this?
Ben Wyatt all the sockets are the same, some plugs do not have earth but must have 3 pins in order to allow electricity to pass through
Here in the UK, all the plugs come with a ground as a standard, also the sockets here have shutters that prevent people from poking objects into the sockets, thus regarded as one of the safest plugs and sockets in the world.
P.S I have used both US and UK plugs and have to say, the British ones last much longer and don't loosen from the socket, which I find very annoying, I remember having to bend the US prongs to keep it in the socket because it would just loosen up.
If an equipment is grounded in U.S. it is grounded in U.K. If it is not grounded in U.S. it is not grounded in U.K. Adding a dummy ground pin does not increase safety.
@@ScottBrady06 german sockets have the same features
Today I learned a new word: Prong, lol
oof
Seriously!? You should've learned this word since you've started 1st grade or told your parents what is it!
Sean Alegada School doesn’t teach you shit about this unless a teacher randomly went off topic or you had a specific electrical engineering class. Your point still stands as I’m pretty sure you’ve seen an electrical outlet since you were young lol
The early part should have been actually about connecting the neutral to the ground. Separate ground wire is another matter. Also it does not say with others have two wires only.
Every single Electrical Appliance here in New Zealand has 3 Prongs. I've always wondered why American Devices only have 2 Prongs. .... Weirdos... 😂😂😂
UNSC INFINITY In America you can actually start to see 3 prongs more often
The equipment that is sold around the world is similar on every country, only the plug varies. It is not that in country X they sell grounded and in country Y not (unless we are talking about developing word or maybe Japan).
Most modern equipment is double insulated. I have some 30 of those: all my TV equipment, phone chargers, lamps, fans, most computer equipment, razors, toothbrush, vacuum etc. I cannot even count. They do not use the earth. If the plug requires the earth like in Britain it is not connected. There are a few grounded equipment. I have eight: laptop charger, monitor, two printers, fridge, microwave, toaster, washing machine. Basically those are in two groups: kitchen/bathroom equipment and computer equipment.
This is an example of an Aussie ungrounded double insulated power cable. Note two holes at the other end:
image.dhgate.com/0x0/f2/albu/g7/M01/05/08/rBVaSlriFnKAe5aLAAR76MYz4n0159.jpg
Have you even looked at the plugs you have. Look for example your TV, phone charger etc.

in Ireland and the UK. the 3rd prong also stops kids from sticking objects Into the socket as the bottom two are closed and only open when the top prong is inserted.
Lol in the UK we've always had 3 prongs
Yeah! and the live and neutral is insulated!
RacingCart - RC Playz Cannot plug Australian 2 pin plug on 3 pin Aussie Chinese outlet. Earth outlet locks both live and neutral outlets. Just like UK outlet both live and neutral locked together if Earth outlet does not plugged in.
Yes every UK plug has three prongs, but not every item is earthed, leaving the third prong useless. The reason for this is so that you don't have to go through the inconvenience of two different sockets.
Ben Wyatt Both live and neutral outlets can be locked together if earth plug does not insert on that outlet.
Plugging your small Europlug 4.0 mm round pins to UK outlet?, you have to plug that chopsticks on earth pin then plug a europlug into the UK outlet.
Europlugs (do you mean Shucko?) can't be inserted into UK outlets, the earthing contacts are on the side, so no earth pin and the pins are the wrong size too, so there will be poor contact which can lead to arcing.
*That awkward moment when you see the title but all your plugs have three prongs*
This is wrong, or at least in australia. The plugs with only an active/neutral are double insulated, they dont require an earth because there is a 2nd protective layer of insulation to stop a fault. And also the earth doesnt stop the voltage from lightening strikes, wrong again.
1st one true for americans, anything with double insulation don't require a 3rd prong. 2nd absolutly true
America is very weird my friend
We know, we know....
Edwardo Ondreseaus Cannot plug 2 pin Aussie plugs in Chinese 3 pin outlet.
all plugs in the uk and Ireland have 3 prongs. phone chargers use dummy plastic ones but toasters and other high voltage apliances use metal earth prongs. We also get 240 volts compared to Americas 120 volts
Why are there holes on the end
Good question.
First off they save money on metal and secondly inside the plug there is a spring activated metal ball or contact that applies pressure to those holes to keep the plug fully inserted and not hanging out with the contacts exposed
Does the grounding really touch bare earth like that? No insulation? What happens if the soil is soaked from heavy rain/flooding? Wouldn't that be quite dangerous since water is a conductor?
Isn't hotwire and livewire the same?
Yes they are just two different names
yes,your home is using AC so hotwire and livewire will switch places everytime
danny santos the hot wire doesn't exist.
Yes hot wire is American and live wire is British
AC doesn't mean it is switching. The live is moving either side of neutral. Neutral is about 0 volts and live switches between positive and negative voltage.
I saw this video in my suggestions a few hours ago... around 20,000 views. And now, a few hours later, it has almost 40,000. Why in the world does UA-cam just start widely suggesting random videos from a long time ago?
So that thing is called a prong... interesting
Voltage is across conductors, it’s current that flows through it.
Then why there are still 2 prongs in some countries?
Michael McNamara because you only need a ground wire if the load you're using had a metal case. If it's say, plastic, it won't conduct, meaning you're already (mostly) safe
+unorthodoxxx There are other reasons too, but i won't bother
Joakim Innvær I'm honestly curious if you're willing
I already did so on another comment
Its internally grounded
Also you should note but unlike most countries and it's not mandatory that the u.s. outlets have a ground Penn. I live in the United Kingdom it is mandatory that all Outlets have 3 pins and all plugs have 3 pins. As a matter of fact you cannot plug anything up if it does not have a ground pin because the outlet will not unlock yes and it's cool right our Outlets have locks on them. Also if you Was to somehow bypass the locking mechanism the circuit breaker would immediately trip cutting the power to that circuit or Outlets.
True but in most British devices the ground pin goes nowhere. The only reason it is there is to open the socket.
In france we have 3 prongs, it's better for security
lmao since when does lawnmower has electronic connection to connect to the house? lmao 😂😂😂😂😂
So thats why at random times when i use a hair dyer the breaker shuts off.
Edit: Holy Crap ive never had this much likes
Or you may have an overloaded circuit. If it's a short it will shut off the breaker as soon as you plug it in. If it's an overloaded circuit the break will shut off after you run the blow dryer and the heating elements power up. If it's at random times like you say my bet is it's an overloaded circuit.
if the breaker is shutting off, the circuit is overloaded. If you're referring to the "reset" button on either the breaker or the outlet, thats a ground fault. something is consuming juice without it being metered back through neutral (the circuitry assumes its following the ground path, or is going through a person to ground) and tripping as a result.
If you've got a fancy new combo circuit breaker, there is also the possibility of an arc fault (which brush type motors are notorious for tripping)
Random Videos check which breaker, if it's Over Current Protection breaker it means you are drawing too much power, if it's Differential Current switch it's probably the heating element leaking to ground.
Edit: I forgot that heaters on hairdryers are not like those on other appliances, I don't know then
If it's a ground fault, the ground fuse shuts off, and if it's an overloaded circuit, the breaker will shut off once you use enough power.
Unless you live outside Norway. In that case, it may or may not be the same.
Random Videos no.. Your "overloading" the circuit... Your drawing to much current. It could be due to a multiple of reasons tho
These have 3 prongs:
- UK which usually found in Air conditioner at least if not in UK probably.
- US that has tube prong
- European/International, although it's not in prong but implemented at the side of the connector as you can see the metal in the border of it.
UK has the best plugs!
Oliver Gray no they don't they can be dangerous
UK plugs are the safest in the world the only downside is when you step on them
Yep are very safe, we even have a switch to turn them off. Ofc we do need this for the higher voltage we use
Foxtail no there not ,any kind of electricity is dangerous even in the UK
+TheTexasOOF Gamer well yea if you misuse it but much safer than japan.
In the UK all plugs have three prongs.
Yes, because the third pin is needed to open the socket.
You have over simplified this, and not all the information is 100% accurate
I can confirm that.
Parts of this video do not make sense.
When your appliances and power outlets have ground prongs but your house doesn't have a proper grounding. Lmao
now I'm concerned about my phone charger which has only two prongs and is starting to expose wire at the end
CheesyPies your phones charger puts out about 6-12 volts DC. Which isn't enough voltage to even FEEL it. Let alone get seriously hurt by it. No phone charger needs three prongs. And if you're still worried, just buy a new charger.
unorthodoxxx 6-12 Volts!?!? just about all phone chargers for the last 10 years have been 5 volts
I have a 15 volt phone charger... Is that odd?
SpiderArtMC is it usb?
Its a quick charge and usb but right now I'm concerned about...WHERE MY PHONE IS!!
In our country, the third prong is usually removed as it is seen as a "useless" feature that was only made to annoy people trying to plug it on a 2 prong socket.
Even if we had a 3 prong socket, electricians here don't connect it to anything at all.
triadwarfare Sounds like a lawsuit waiting to happen!
In Japan? Surely in Asia.
So wrong in so many ways........
.......
in europe all appliances that use water, must have 3 prongs.
due water being able to shortcut the circuit.
also in the EU the 3 prong connector is more safe than the usa version.
since the usa version is flat on the wall, while the EU version is embedded in the wall socket
Ok, guys if anyone is from England here, watching this video (which I am British) they would know that all the plugs that we use have three prongs, and this is just something in our everyday life. We don't find it odd, and I thought everyone had these wires. But considering that I'm 9, I haven't been out of my own country that much. But this is classic America, to not think things through. Sorry to say, but my empathy isn't turning on right now.
FluffyStuff mhm
I like the UK plugs and sockets a lot more they are far safer than the US ones (I'm from the US)
FluffyStuff Apparently unearthed devices do exist. It’s just that you guys need the 3rd prong to open the shutters for it to actually get plugged in. That is pretty clever though. Nobody is gonna get shocked from that.
In most of Europe the covers work so that you need to plug both pins at the same time. Some British outlets also have this in addition to the earth pin. The problem with the British system is that a kid can first stick a needle to the earth. Then he can insert it to the live and if he touches both that can give a fatal shock.
The ground prong usually points down, but is SUPPOSED to point up so that if anything falls on the plug, it will not short between neutral and hot.
No, that is just your own rule. The code does not say so.
Isn't ground on the side of the plug
No
they're talking about american plugs, since half of them have bread for brains
Why the hell did you ask if you knew the answer? Besides, In Britain (my home country) and America (the subject of the video) The earth is not on the side.
Joakim Innvær It least we've been to the moon.
Yeah, i guess you have that going for you, but you also have feminazies, trump, and many other breadheads
1:50 For some reason, I jumped.
If u had good education you would have already know this
Winnie Chen unlike you
yeh i learnt it in physics lmao
Winnie Chen If you had a good education you would know how to spell "you".
thats so stupid to say, its an abbreviation that she used. if i was being as picky as u, i would say that you should have written 'you' in quotation marks..
Hamzah Shafi Nice grammar.
As I'm sure most people know, schuko plugs don't have a ground prong, but instead have contact plates perpendicular to the power pins, that make contact with springs in the outlet. But it does the same job anyway.
Germans made it right. Schuko fits old ungrounded outlets but not the other way around. No need to cut any springs when you have old outlets. The French one is also similar with the earth pin. Danish on the other hand have an earth hole. The Danish outlet accepts schuko but it does not connect the earth which can be dangerous.
Most grounded plugs now are combination of schuko/French.
When you're European, and your mind is blown that most Americans don't know this basic knowledge!
In Ireland the third prong is plastic, and it is to prevent babies from shocking themselves is they put their fingers in the holes by closing everything if the plastic prong isn't there.
The third prong is plastic if the item is double insulated, if not then it's metal for earthing. Yes it also is for opening the socket shutters to prevent electric shock.
If can be metal even for double insulated.
If you did not already know the difference between 2 and 3 prongs...you really need to go back to school.
David I always thought it was common knowledge as well. i clicked on this out of curiosity and I'm pretty confused as to why so many people don't know what grounding is.
David
this video popped up on my feed. I simply watched to leave a comment for people named David who didn't know the difference. School is cool David ✌🏼.
Are you talking primary or secondary school? I know that from 1st though 12th for me they never talked about plugs in any of my classes. In fact the only plug talking that went on in my school was for drugs.
This makes so much sense now. I use to hate 3 prongs cause some extension cords don't have a third hole.
None of the outlets in my apartment are properly wired. There's missing grounds, and reversed hot/neutrals. I don't have access to the breaker boxes, so I can't add grounds or swap any wires myself. If the conduit boxes weren't originally grounded when the building was wired, then screwing things to the middle screw is futile.
How does the fail work in this case?
Missing ground is serious if it is only on some outlets. Reversed hot and neutral is really a non-issue. Only think is that if you have to operate with a lamp for example like to remove a physically broken bulb you need to unplug. You should do it anyway.
Lack of grounding is not really that severe unless there is ground nearby like radiators, antenna cables, grounded equipment, water or if there is conductive floor.
It is possible to connect the live and neutral on the socket. Whether this is legal depends on the local laws. There is a risk if the common neutral/ground breaks then all equipment become hot. Also it one accidentally connects the live and ground it is extremely dangerous.
I remember when I was very young I touched both of the two prongs trying to unplug something and being shocked, to this day I'm very careful unpluging things now.
The grounding connection isn't need if insulated
How do I check to make sure the ground is wired correctly? This is a 1963 house and still has the original fuse box. Not sure if any of the other electrical stuff has been redone or if the outlets were ever replaced.
Use a multimeter. Set it to AC voltage and measure between the live plug and the ground plug. If you have a good ground you should have around 120V on the multimeter (give or take)
It's funny about the grounding wire tripping a breaker in the breaker box, because GFCI outlets do that as well, which are are usually mandatory in areas with water, such as kitchens, where metal appliances are commonly found. I suppose it's still good to have them for backwards compatibility, in case those outlets were installed before that code was written, but it kind of makes one wonder if it's really necessary to have multiple backups that function the same way 🤔
If you don't have a ground wire for an old two pronged outlet, it is acceptable by NEC to replace it with a GFCI outlet and label it with "no equipment ground"
The earth and breakers protect against completely different things. Breakers protect you from power surges whereas the earth protects you in case something with a conductive case malfunctions and the case becomes live
Fun fact: The way most of us are used to seeing outlets, the classic I.l style, is actually upside down! The ground hope should be on TOP, *not* bottom! That way, if something falls on a grounded plug, the ground prong won't spark a fire.
why do ac adaptors only have 2 prongs and each prong is equal sized and works in either orientation you plug it in ??
Another reason is so it doesn't fry your Electronical Device if a Sudden Power Outage occurs or if a Lightning Strike Happens. Basically diverting the Electricity that would of Destoryed your Device and/or Killed you, And bringing it into the Ground.
I haven't watched the video yet but in short terms:
2 prongs is used for devices that are Internally grounded
3 prongs are for items that are not internally grounded and rely on grounding the item through well.. the ground
Internally grounded makes no sense. They are double insulated.
don't break off the 3rd prong to fit it into an extention chord, unless you have to, then it's ok.
in my country this video would be titled why some plug sockets have 2 pins rather than 3 pins
my air conditioner and automatic washing machine uses 3 pronged plugs.. but we usually have 2 hole sockets here in the Philippines.. i just used an adapter to use my appliances.. but the manual says not to use adapters or extension wires for it...
Yes, because if the ground isn't connected, and you have an internal direct short to ground, the circuit breaker won't trip and you can get electrocuted.
@@some_name9306 thanks
In the U.K. all of our plugs have 3 prongs. This is regardless of whether it's a full-on gaming PC or just a kettle.
Well not all appliances here are earthed though but both a computer charger and a kettle would be, based on the fact that if you are in the rest of Europe those have earthed plugs with the earthed contacts on the side for schuko used in most European countries, and also a hole for French sockets, that are also used in a few other European countries (all plugs, except very old ones, work in both sockets) but things like lamps or double insulated appliances like a vacuum cleaner or hair dryer aren't earthed even on the UK, even though there's still a 3rd pin, which is needed to open shutters over the 2 main contacts for the live and neutral
Wrong question.
Why some have 2 is a mystery I can't get over.
Now that you answered this question , why does some have circle prongs while others have parallel?
Basically, different countries created their own standards and by the time anyone thought it was an idea to implement a global standard, it was too late as existing standards were too established and it would be too hard to change over
do i still need the third prong if my wall outlet only supports two? Can I just remove it since there is no ground on the wall outlet?
@wytonjedi Correct. Never remove the 3rd prong.
3 sprongs means for the other outlet numbers like 3 means required 3 sprongs
Good short explanation, like it. Hopefully it'll teach people
In my country they all have three pins (except electric shavers and toothbrushes), but sometimes the third pin is plastic.
For ultimate safety, we should all use 4-prong power systems. Cheers!
My dad just casually removed the 3rd prong on my 3-prong charger as if it's a tick on a dog.
As an electrician this is so funny because not even the creator of the video can really explain this in a good way... lol
Yeah, and the reason the power is cut off when there is a direct short to ground is because its basically creating a short circuit between live wire and neutral wire, since ground is always bonded to neutral at the main panel, not simply because there is voltage on it.
I still like european plugs because I all have european plug things in my wall, I don't have american ones
I live at belgium and they don't make those prongs like in the video and they also don't make those american plug things for your wall in my country
I'm glad that adapters exist
I once bought an object on ebay which has an american plug on it with 3 prongs
I forgot to look what kind of prongs it had
turns out it has an american plug cable and not a european one
so I bought a US adapater with EU prongs on it so I finally can use the thing
I have the reverse on some of my stuff lol.
are you sure your american plug object is about 230V?
And I used to to remove the third prong on our laptop chargers.
one time the gable guy came to our house to hook up the cable but we lived in an older house so the outlets didn't have a ground so the cable guy broke the ground of the cored and plugged it in
1:14 Voltage doesn't "travel through you". Current does. Voltage and current are not the same thing.
