You know its funny because i never saw your face, but a saw your cat a lot so i imagine you as a cat
Owners and their pets often look similar in a way.
There is a video on his Czech channel where he shows his face, no gonna give any links though.
Enzo Perruccio check out his website too
no face reveal necessary
@Francisco Balderas weird flex but ok
All people that have cats are crazy.
Even the cat got scared away @1:40 😂
The white powder is meant to be magnesium oxide, if you ever burned magnesium ribbon at school then this is the white ash left over. and I think the coiled wire could be an alloy of tungsten.
I previously thought that the weird white powder is salt. Because salt is an "ionic compound made up of two groups of oppositely charged ions". And ions are "atoms with an electrical charge."
Why not dirt cheap waste nichrome?
Imagine if the police showed up.
Oh shit !
LOL
Coke, for sure!😁
That's creeeeiiizeeyyyyyyyyy!!!!!!!!!!!!!!!!!!!!!
Thats dooooodgyyyyy!
lolz
Are youu kidding me guyyeees
This is like a dead short serciiit
@TALU nothiiiiiiiiinnnnn, just never heard it beforrrrrrrrr
It's a common practice, manufacturing resistance heating elements, to fill the pipe with compacted dry silica sand before bending. The problem is that the sand, in your case, was not compacted and appeared to be humid - probably the leak was the humidity in the sand - poor manufacturing quality and control (no high voltage leak test), as one expects with these cheap Chinese appliances.
maybe.
But once you bend it, the coil will become un-centered. I suppose if you properly compact the sand, it should hold it in place, but then China is not known to do things properly (their buildings are literally crumbling: th-cam.com/users/results?search_query=china+falling+down+apart ). ¬_¬
I love ur accent so much with words like...
Bloody hell
Seriously!
And how can j forget...EVEN MORE SALT
My favorite is _dangeroos_ , but he didn't say it in this video :-(
(I'm not sure why, but I think he's Czech. 🤔)
bloody hell
yes czetch
Yeah I can confirm as a Czech myself he is Czech.
Blady hel!
Dengerus!
Doji adaptør!
Great job. You continue to inspire me to get rid of four decades of gear and learn again how to use a DMM. Thanks.
Hey, my wife thanks you for getting me to think of unloading 5 ton of gear in her basement.
Happy Christmas DGW, and thanks for your marvelous entertaining videos. They have been great fun to watch.
3:25 BLADDY HELL
Merry Christmas thanks for continuing your channel😇
I took apart the heating element of a coffee maker once, the heater was constructed exactly the same as this one, so unfortunately this danger might not be uncommon.
No risk of fire, the powder is most likely pure asbestos. ;)
If it’s asbestos then it’s still dangerous.
r/woooosh
@@eriknestaas2270 put me in the pic atleast.
Im worried because it could really be asbestos...
Wow, that's dangerous... scary! Thanks for the review & autopsy.
I died at 3:29....'bloody heeeell, ceeeiriosly' 👍👍😊😊😂😂 But I would most probably have had similar reaction to a 'dead short cerquit! ' 😂😊 we love you, keep these vids coming!
The moment I heard the words 'Chinese Water Heater', I knew this was not going to end well
you forgot to throw the cat out of the window!!!
it could be ELECTROCUTED!!!
Of coooouuuurseee!
The cat goes behind the door and not just to protect it from electrocution. It needs to be protected from fire and explosions the Chinese devices typically produce.
Meow
The powder is normal, it is also present in high quality heating elements, it is usually magnesium oxide, which is a refractory material and a good insulator, I went on a tour in a heating element factory, and yes, the manufacturing process is pretty much just that
I believe the problem is on one if the two ends considering your measurements
I think that in good heaters the powder material should be at least a bit more solid. Maybe just more compacted, maybe soaked with something to make it solid.
@@DiodeGoneWild Yes, it is indeed a finer powder and more compacted, I din't see the powder up close, but I remember seeing a section of a different style of heating element that was rated class II and the powder didn't come out like that, it stayed compacted, so yes, that could also be another sign of cheapness on that dodgy heating element
Bloody hell!
I burnt my fuse using "This dodgy Satan's Machine".
Your diagrams are amazing.
Dangerous supply , Thanks for sharing this video .
Haven't a great time .
Thanks for the interesting autopsy and important safety information! Its really horrific how they treat these safety issues in China. You cant be careful enough with those things...
Are you kidding me guysssss ???
Ow er, bastards arnt they, not even a high temprature woven covering to insulate the nichrome wire :-(.
Not even an earth.
Big clive calls that plug a DeathDaptor :-D
You don't have earth leakage or rcd fusebox protection.
Yep keep puss safe :-D
he does, but it only trips at 300ma.
if he was in the bathroom it would trip at 30ma and would have tripped
Well, sand is the cheapest insulation :). They don't care about earthing either. They just use the "don't touch it when it's running" logic. My wiring has an RCD, but only for the bathroom. Other rooms only have a 16A breaker and no other safety. Wirings from a certain era are like this. The cat was in a safe place, no worries ;).
It is like this because if you would connect your entire house to the RCD, it would need to allow more leakage margin to avoid getting activated when not desired, reducing the safety. Therefore they were restricted to high-risk rooms.
Nowadays we can manufacture them cheaper (in China :) ), so it is no problem to install as many of them as needed and we can protect the entire house.
My guess is that in the middle part where the "sand" is not compacted well, the heating wire has enough "wiggle" room due to thermal expansion/contraction to get close to the metal pipe, and create an electrical leakage. While it's true that most bathroom trippers will trip before it gets too dangerous (50-100mah), the mere fact that they didn't even try to isolate it better is a total disregard of quality and safety.
Well, it might be more of a production problem than a design problem. Often Chinese devices are somewhat okay designed, produced by many different producers, who are in their price wars fuck it up. We can see a production error here: The "sand" was only solidified near the ends of the tube. If the sand was fully solid, you would have isolation between live wire and the tube covering the heating element.
Now there are questions to be asked about the design: There is no ground plug, is just the sand enough etc. However, the theory that the design might be compliant with Chinese electrical regulations (that are not so strict as ours) and the production being fucked up, due to price pressure and inexperienced manufacturers, sounds plausible.
Not gonna lie my dude your voice melts me ;)
This Water heater inside consists of silica sand and nichrome wire heater element.
Great tutorial
I watch your videos and are amazing!! good job!!!
At some truck stops in the USA, you can find a 12V version of this device made for coffee mugs. The heating element is surrounded by metal and makes no contact with the water, so there's a small chance of electrocution. But there is no overheat protection, so it can boil away the water and become a fire hazard. Also, it plugs into your cigarette lighter plug. The current it draws is excessive for that kind of plug. It will (and really does) slowly melt the plug down. Not only is this a fire hazard, but can get hot enough to burn your hand when you go to unplug it.
The big problem with it is that the connection at the lighter plug forms a voltage divider network with the heating element. Thus, the plug and socket becomes almost as much a heater as the heating element. To stop this, one has to reduce the resistance at the plug. This means replacing the plug with something else entirely. My solution was to install a pair of RCA jacks right next to the socket, and wired them up to hot and ground. Then I replaced the plug with RCA jacks. This left a small 13.5V shock hazard, but the resistance dropped so low that the heavy lamp wire became the next highest resistance. The wire warmed up more than the RCA jacks. But at no time was the wire too hot to touch, so I deemed this an acceptable solution.
Don't worry, there is no way to get shocked with 12V, except maybe on the tongue :)
@@drobotk Not so. A guy I knew was working on an F-4G with the jet engine running on a very hot day. A running jet engine produces an enormous amount of current - both 120VAC and 12VDC. When he got hit with 12VDC, it put a hole right through his thumb and simultaneously cauterized the wound. His thumb looked and smelled like a burnt hot dog. Lucky for him, he didn't lose his thumb, but there was some nerve damage.
You should also know that arc welders are low voltage, high current devices.
You accentuate in such a unique style xD
I think they are also counting on the oxidation of the wire adding a bit of a resistive barrier once the device is fired up a few times. The sand transfers the heat and also allows them to bend the tubing, perhaps induction heated. Who knows, not the best design regardless.
Tubular heating element are usually made of, magnesium oxide and not send.
Because magnesium oxide has very high melting point 2,852 °C (5,166 °F), and it's also much finer powder compare to send. It can be packed more densely compared to sand.
Hello Mr wild. I'm thinking about using a SSR to switch mo well pump. It is 120v and I think 7amps. I am thinking the zero crossing switching will be easier on my Inverter. I am off grid. And need to care for my inverter. Will this help inrush current spikes? Thanks man...
the real question is why isnt your breaker tripping when you put live to earth 90 miliamps should trip the breaker (safe house you got there, or do you have a isolation transformer or how it is called)
with a normal immersion heater, would i get electrocuted if i were to touch a titanium rod which is in contact with the heating element? (the titanium rod end inside the coil of the heating element?)
You can increase the clamp meters resolution by wrapping several turns of wire around the clamp jaws.
correct! every turn increase the current 1 time: 2 turn double current, 3 turn triple current and so on.
So, make turns an divide by number of turns to obtain the correct value (in a perfect world)
I might be guessing that the weird white powder is salt. Because salt is an "ionic compound made up of two groups of oppositely charged ions". And ions are "atoms with an electrical charge."
But if it's really salt, what is it's purpose on the heater?
LOVE this guy's accent
Hello diode. I was serching on ebay for crismas lights and i found a 220 v dougy
Sorry for the bad english🤣
Nice I like the works.
another good video thanks!
Yay!!! Another videos! :)
I think it is silica sand for insulation .
This is why you always should have a differential circuit breaker in your residual electrical system.
Thank you sir
The white isolation material is electron emissive when heated. That's why it passes current in one direction.
No, there's no vacuum, so there should be no electron emission. And the voltage is AC, the current is not passing in just one direction. It's passing in both directions, but from just one end of the resistive wire.
Useful video
Which one is to buy to touch the water?
Another gem of a video. Do another alien video. Love the alien stuff..lol
Is that nicrome wire?
I have a similar one (bought in Ukraine a few years ago). The voltage between the "water" and neutral is 30V in one polarity and 205V in the second polarity. However I was not able to measure any current leakage. I even wound the wire 5 times through the clamp to increase the sensitivity. But in both polarities, it showed 0mA. Btw. I used the same meter as in the video. I still use the immersion heater to heat up milk in a stainless steel can before proceeding to make milk foam with the aid of the coffee machine. Cold milk directly from the fridge does not make a nice foam. It needs to be warm, around 25°C - 30°C for best results. I usually use the heater only for 15 or 20 seconds and wear slippers with a thick cork and rubber bottom, so I am isolated. So even in case of a leakage, I would not form a connection to ground, even when touching the stainless steel can. I assume that milk conducts electricity at least as good as water, if not better. I do not have a microwave oven and even if I did, I could not put the stainless steel can into it. Since it is stainless steel, it does not work on the induction stove either.
Maybe having an rcd device would be a good idea
@@HA05GER I have it, but what use does it make when the appliance is not grounded? Only grounded appliances can trigger the rcd device, when some of the current flows not through the neutral wire, but the ground wire.
@@erikziak1249 that's not true what so ever and RCD monitors the live and neutral conductors to see if they are balance. If they become unbalanced like you get a shock or leaking to ground the RCD will trip.
@@HA05GER Thanks for correcting me. You are right, it checks the live and neutral. The RSD device should trip even if the appliance is ungrounded, but finds another path to "ground" other than the "working neutral" wire.
@@erikziak1249 correct 👌 so should keep you safe with something like this.
This is why we need lawsuits.
Sadly China doesn't have safety laws.
Of course China has safety laws. This would not pass any Chinese domestic electrical standards either.
@@johncoops6897 No shit Sherlock!
Every country has safety laws. Laws are meaningless without enforcement.
Now go away and don't come back.
@@pirateman1966 - so, first you say that China doesn't have safety laws.... then you agree with me that China DOES have safety laws? ROFL.
The safety laws that are being broken are those of the (export) country where the product is being used. People should not import things that are non-compliant, and it is lack of enforcement in the OTHER countries that causes the problems.
@@johncoops6897 Piss off troll.
@@pirateman1966 No need to be rude. YOU were the one trolling these TH-cam comments with your inaccurate bullshit. You should be more graceful and apologise when somebody catches you out.
Probably, the sand is pressed at the ends and so it is such "solidified".
I had a bitter experience with one of these heaters ( 1500w, bigger version), it was running on mains while dipped into water.... suddenly the pipe leaked and the powder(sand) was thrown up all over the room, the whole room became foggy!
Though it was of an unknown brand, then I bought a new one from Bajaj, it is working till now....all perfectly grounded and so on.
Can someone explain to me why this doesn’t trip the RCD of the circuit breaker??
Make a video on how to make a big battery 120 acv with plugs thats rechargeable for your ac tools etc
3:26Are there little sparks on the water heater?
Greetings from germany
Good for replicating at home.
Ich denke die Isolierung besteht aus Quarzsand wie er auch in Sicherungen verwendet wird
Nice video! That powder inside is probably magnesium oxide.
Nojo už vím proč mě odpovídáš na emaily tak opožděně, ty si hraješ zase s topným tělesem :D už je mě to jasný :D
Are you KIDDING ME GUUUUUUUUUUUYS?????
Silver sand is used as insulation.
Surge Protection Devices test and autopsy?
Pyro or MICC (mineral insulated copper cable) could explain the sand. Its an excellent cable used outside, fire alarm systems etc. The mineral insulation compresses the same as the copper cable so can be bent and even hammered flat and not short. I know because ive tried :)
Im not saying this Chinese element is the same quality but maybe they tried to clone the method and thought sand would do the trick ;)
That's amaziiiing!
I wonder what that white pouder might be 🤔
according to my calculations, this device is actually fairly accurate, it is 2.77 amps 230 volts 85 ohms and about 500 to 600 watts
Máš krásnou kočku 😁
That looks like a cheap, dangerous imitation of a cable we use here in Canada called PYROTENAX. Look it up...
The isolation powder can be (among other things) magnesium oxide.
They could isolate the resistive wire with glass dust and it could be a bit safer to use, but Minecraft said: you make glass out of sand, glass is not conductive so you can just put stupid sand from the beach
Great video as always! By the way i think that some drug dealer hid something like white sand inside replacing real insulation :'D
The white powder is probably cocaine ! 😁
Mmm I love nose candy!
Shouldn’t that amount of leakage current have tripped the RCD?
I like your clock
1:27 - clamp meter looks like faulty time machine. :D
I love all of your videos and I think you should keep doing it and some of the dodgy Chinese electronics
You get are really bad even your cat doesn't think it's safe to do pleas be safe because here in Scotland ware I live the plug sockets are different and you can only pout it in one way or you will brake the socket and what' you plugin it will brake
Now you see why they did not ground the metal.
How come you haven't tested and taken apart an electric hurdey gurdey? I'm sure it would be of much interest to many as no one on TH-cam has really taken apart one
3:29 ‘bloody hell are u kidding me guys’ 😂
3:47 ‘bloody hell’
"They bended into the shape"
surprised you can buy em online
Lol that lamp worked by reverse polarity of the plug but 220v does not have polarity ? Right ?
Diode Gone Wild power line is feeded from a 380-220V 3-phase system:
this power transportation system is made with a neutral and 3 phases.
If you pick tension between two phases you have a tension that is 1.73 times higher (380V) than if you pick between neutral and one phase (220V), it is non relevant what phase is.
With this system you can sell threephase power and monophase power in the same line!
The neutral wire is grounded along the distribution line (for line protection purposes) so in your home you have a live wire and a neutral (grounded) wire.
When you try to measure between live and ground you have 220 V otherwise if you measure between neutral and ground you find almost zero ( teorically zero if your grounding plant is 100% functional)
So if the lamp is connected between to the live wire and ground, you can light up the bulb; otherwise if you connect the lamp to neutral and ground the bulb does not light up (maybe slightly light up due to the low voltage between neutral and a not very good grounding)
Tha's why you act as reversing polarity because you change live with neutral but it is only an asymmetrical distribution system
p.s. many years ago in some italian countries you'll can find the obsolete 220-125V system (in way of decommissioning)
It is the same kind of transportation but in home you have two phases at 220 V and in this case each phase is only 125V apart from ground because the neutral (not present in that home but present on feeding line) is still grounded
3:30 normaly you should cry about that, but I couldnt hold because suddenly the accent went through the roof xD
John Ward tested this device on his TH-cam channel and came to exactly the same conclusions.
In other words - if you get a short, just shake it up to realign the sand, and you should be fine. Totally safe.

Very dangerouuus product. The background sound of ticking clock. Must be a mechanical spring would clock.
Yes, I have a Mauthe mechanical clock and several other Soviet and Czechoslovak clocks in the room :).
Keep your finger away from the lamp. We need you for more videos!
No worries, I keep my finger at least a centimeter away, and I'm far away from anything grounded, just for the case I touched it...
Et le 30mA ne tombe pas?
Holy shit you're a funny sounding big clive!
Cool cat!
I Love Your 🐱 And Your 🐶
edups?
I was expecting you to put the resistive wire in the water alone and plug it in at the end of the video :(
I would be a bit more concerned about getting mystery white chinese powder everywhere
I know that the plug is dangerous and it leaked current after few minutes but hot water conducts better
Awesome video, how to contact you? my dear
Very good Czech accent.
at this point, I think you can check that this powder is not asbestos ^^
