- An interesting, but flawed connector from eBay. This one has the exciting feature of being able to be plugged together incorrectly, with a risk of making the case of the connected item live at mains voltage.

In risk analysis we call that "reasonably foreseeable misuse" and yes, you are meant to take it into account.
In layman's terms it's called "idiot-proofing" and it can save lives.
@@PunakiviAddikti I tend to reserve that term for preventing stuf that's way harder to do by accident than misaligning a connector by one pin single-handed in the dark. But I get what you mean.
@@PunakiviAddikti You can't idiot-proof something. Whatever you do, a bigger idiot will find a way
isn't this what Murphy's law originally ment?
"if it can be installed wrong at some point it will be installed wrong"
I feel like this video is more than enough disclaimer to go ahead and NOT try to connect them both live and blind. I'd rather have a connector like this that can be plugged wrong than gendered connectors that cannot be used properly without adapters. Such as 2 pin battery cables, found on 12v chargers and powersports. If you want to "boost" off the plug on an ATV, and want to use battery charger clamps you already got, you gotta reverse the clamps or make an adapter. Whereas here you just match the colours.
I'd listen to this guy explain how grass grows
Thank you for the warning, Mr. Connery. You truly are the man now, dog.

Great catch Clive! The literal definition of “Plug and Prey”! I can’t count the number of time poor assembly design had forced me to plug connectors together by feel only. A certain disaster waiting to occur.
Plug and Die would be more accurate!
Prug n Pray!
You're the prey😂
There's one live and one neutral not connected. Please explain how it is dangerous if you don't have a completed circuit.
That was my grandfather's house... And he was supposed to be a carpenter
I bought some of those connectors for low voltage stuff thinking that they would be an ideal replacement for a RS one I’d been buying for 20 years, that got discontinued.
I liked the so called universetality of them until I realised that although the connector is universal the color coding isn’t, because if you pick up random connectors it possible to wire red to blue and blue to red .
I also picked up on the offset pins thing last week on a LED pixel job where I realised if the connectors weren’t plugged in correctly I could put 24v onto a 5 volt data line causing dead pixels .
I put those connectors on them at points where this Chinese dragon lantern i was working came apart for transport only to find at the gig at a 5 am load in that the warehouse staff took the connectors physically off the cable with the lever pins rather than just pulling the connectors apart …
If you ask me -- and, yes, the fact that you didn't hurts ;-) -- I'm inclined to agree with the warehouse lads.
i feel like this is a r/rimjobsteve moment considering the username
The manufacturer forgot Murphy's law 😂
When I was an electronic engineer we called things like this "one mistake" components.
You know… this feels like something that an assassin group’s front would slip into public use to make their jobs way easier… all it takes is one ”accidental” connection and suddenly the entire server room is a bug zapper…
rule one from two electrician parents: "in electricity, easy kills." They were talking about this kind of stuff, as well as taking shortcuts with electrical safety. If its easy, youve made a death trap, not a circuit.
That is a lethal design feature.
John Parker: "It looks like one of our thermopods, but it’s a very bad design." ("
It's honestly such an easy fix to make it only work if everything is lined up properly I'm surprised it wasn't implemented in the first place.
Just add posts that are offset on each side. One high and one low. It'll still connect the same way but now it can't be connected as demonstrated in your video.
Another public announcement well presented. Now we just have to sack the officials that allowed this into the UK
The manufacturer should consider a poka-yoke feature for avoid that!!
He's like a Scottish Stanley parable narrator
Sounds about as safe as a Male-Male Extension cord, can't imagine how it's even allowed to be sold.
Great video, and a nice warning.
I'm grateful that the ventilators I've work with, for my patients who are dependent on them, are basically idiot proof now days. sometimes the hardest part is hanging a new bag of humidification water (labeled caution not for intravenous usage) up. sorry I'm nit in the electrical fied but that misalignment looks like it could be fatal to me.
"This can kill you."
What doesn’t? 😂
thank you, stanley parable narrator
Shrek explains connectors
Yeah those plugs definitely need a 1 way permanent sleeve.
The product is a good idea. If they put flanges on the sides, and/or made the shapes of each connection unique they could prevent this from happenning.
I’m surprised that was overlooked. All the had to do was set centre connection to slot in differently and it’ll of worked fine.
Still want them. It could be great for low voltage automotive applications. The ham radio guys might love it too.
Simple enough to fix. They just need to make each color socket a slightly different shape. That way it only fits together the correct way.
It sounds even more ominous because the narrator sounds like Liam Neeson.
This would be very easy, and cheap for the manufacturer to fix going forward by just making the shape for each plug a little different like you see on 6 or 8 pin connectors on a PC.
From the moment live touches neutral or ground the whole breaker trips almost immediately
This problem can be solved by placing plastic extensions to prevent the wrong wires from being connected to each other, such as the power supply wires in the computer when we connect them to the motherboard.
It's a really bad design if it isn't keyed in any way, but that's exactly what RCDs are for.
If you haven't got an RCD/Gfci at home, install one. It's 20 bucks. Even if there's no ground wire from your mains supplier, they can still offer some degree of protection. You can also get an ok ground connection from a metal water pipe or something similar.
"this connector being sold on ebay can kill you, let m-"
"SOLD!"
Any connector can kill I'd you put the wires in wrong, it doesn't matter what connector it is! That's why electricians exist.
Any connector can kill if you throw it hard enough.
Electricians make dangerous decisions all by themselves in the industry. It's is incredible what wiring I have had to correct that both technicians and electricians decide is a good idea just to keep machines running and circumvent safety.
Hot Take apparently: If you are working on live wiring you are already in breach of safety procedures. You are responsible for taking measures that ensure your own safety.
The solution is to make phase specific shape, so wrong phase doesn't go to wrong connection
I have to admit…when I first started watching this, I thought “great, another nervous Nellie complaining about something.” But then after watching the video, I stand corrected.
The end, though, results in horrible things.
It just needs a key moulded into it
it would cost nothing to prevent this, with just a small change to the design
My reaction:
"This does not look sketchy at all"
*live earth happens*
"ooooh...."
That's why it should be designed with a fail safe built in like most harnesses can only be plugged in a certain way only
Designing it as a hermaphroditic connector is itself a serious hazard, even before looking at the universal design. There's a REASON that all safe designs to not allow you to just connect two independent building power circuits together.Even if you don't shift the plugs to connect Hot to Chassis, there is nothing preventing two 'line side' plugs from being plugged together, cross-connecting Hot and Neutral.
Dude sounds like the Stanley parable narrator
Natural selection sounds like it's doing its job correctly. Who handles electrical equipment without paying attention to the live feed areas being connected???🤔
It's so funny that computer hardware has solved this particular problem like 30 years ago. Just shape the damn connectors so you can only plug them in the correct way.
Usually you would change the orientation of the middle pin so it can't be connected ina wrong or reversed way
That's why you connect it to ground (earth) before you make the live connection.
At my work we have connectors that can kill you too: via blunt force trauma. They built tough and are heavy. Theyre great but a pain to assemble
It wouldn't even have been difficult to key the connectors so live in can only be plugged into live out.
Simple fix to design, make middle connector pin staggered to the left and right.
Everything is possibly dangerous if someone is dumb.
Ok guys, make the center one a circle.
It's a connector for low voltage systems. That would melt under industrial load. I really wouldn't want use above a 24.5v system.
Wow that is a terrible design flaw! Funny how EVERY OTHER PLUG (well a bunch)can be plugged in only one way😂😂😂
Thanks for the info!❤
And if I turn my wheel slightly towards oncoming traffic I'm dead.
Excellent warning. Thank you. Theres probably a life saved somewhere.
So that explains the tiny bit on each side that is a pain in the ass..
Understandable.
I thought it was legos for a min-
Another design that has no regard for safety.
If you have a earth fault breaker then as soon as you misalign those, it would break the power within a second
Best to use it for super low voltage. Like Legos for children's toys that use a single AA battery.
''horrable things can happen'' lol he said it like every mage npc in rpg games
Reminds me when i misaligned the floppy drive power connector, burned the power wires, the hdd and somewhat the powersupply unit. The smell was horrible.
Looks like a LEGO part.
Its small enough to be a choking hazard to.
Yes. Be careful not to put it in your mouth.
"Let's make a connector that can connect to itself."
'Awesome, but won't the colour-coded stuff be the wrong way around when you connect one to the other?'
"I have a great idea: Let's sell two different versions of this connector, that way one can plug into the other without the colours misaligning."
'Wow, that's a great idea that doesn't exist on the market yet, let's sell it.'
I think I've heard this guys sweet voice before... On every single BBC documentary ever made 🤣
Id like to think id be beyond making such an obvious mistake like that, but whos to say this connection wouldnt be sitting behind hundreds of other wires, obscuring my vision while i try to fiddle with it 🤷♂️ they should definitely use some obstructive feature to make this impossible to mess up
Damn, this small of a connector can hold a deadly amount of energy/voltage?!
Isnt that how Murphys law was invented?
Couldn't find in America!? Is this why Britain is so Great!? 💯😂🎉
Funny how this automated voice tells you they're dangerous and then hes got a whole pile of them in the background 😂
It's my real voice.
@@bigclivedotcom Dang, do you ever try to prank someone with that voice?
A simple fix would be something like we see connectors on a computer motherboard.
This is why regulations exist, folks.
If that happened a breaker should trip
It would be curtains for you! 💀
How in the living God did the design engineer overlook this??
Poka Yoke go!🤣
In the example in the video, neutral in the device will be connected to earth. If live is then connected to the chassis of the device, I think enough current will definitely flow between live and earth in order to trip any RCD. Still a really terrible connector though.
Just make 2 wires one for case one for the rest
It’s not the connect that’s dangerous. It’s the fool that’s using it That is dangerous. They just need to redesign it a little bit.
I thought these where Legos
Well you can also accidentally stick you hand in a blender.
Yes you can. But the blender is less likely to kill you.
This as a PERFECT gift for Electrobooms birthday. 🎁🎂🎁💥SENDING IT OVER TO HIM NOW!😀
This could only happen if the case was not earthed.
This IS the case earth if something like pump is sitting on an insulated surface.
Always cut power at main bus, then connect thingy, then return power from specified distance....
The RCD would hopefully pop.
i wish you hadn't shared that knowledge to the luney tunes amongst youtube viewers
These are made to be used for bench testing.
Don’t tempt me with a good time
Well done for the video, they should have made it so that you can only plug it in from one side
So basically,don’t misalign the connection..got it
Im convinced the Chinese are like that book smart kid who had all the best grades but had 0 common sense
Yeah but luckily in the EU ground fault protection is mandatory
At first i thought that you're just another pro-wirenut-wago hater, but then you pulled it apart, and i immediately went NOPE myself lol
I’ll take three.
Don't plug it in wrong then. Simple.
You say that like it's a bad thing.
So ...if i touch the surface i can get zapped ? Cool.
I thought this was some sort of useless toy until I saw the title lol.
It would just trip the breaker
