_How Safe Is the Shower Head of Doom_ 5 minutes later: disassembling oven

So, my thoughts as an Electrical Engineer from Brazil: It's pretty rare to get a shock from the shower head directly even if installed incorrectly due to the fact that the tap water in droplets doesn't conduct a lot of water and the shower head is made out of plastic. In properly installed residences, it has its sole running circuit from its own breaker to the shower and uses 220V power (we have both 110V/127V and 220V over here) to dissipate less heat in the wires. It is way more common that due to not installing the ground wire or the resistance correctly that it contacts the pipe (in older houses made out of steel) and give you a shock on the handles when opening or closing the water. In that case, a quick fix that most Brazilians do is either use a rubber mat or a rubber flip-flop (which is ubiquitous over here). To conclude, here the houses are made from brick and mortar and it's way more resistant to electrical fires compared to places like the US or Canada, where the insulating materials can be a hazard for high powered electrical appliances. In my opinion, having a gas pipe installed only for the shower is more hazardous than the solution we've got here, since heat is rarely a problem in a tropical country like ours.

Let's also remember that water is a poor conductant. If it was salty water then it would be a whole diferent story. Here in Brazil we have the majority of showers eletrically heated and a minority heated by a buthane/methane mixture. It is common to read about asfixiation accidents related to gas heating, but in 53 year I've never heard of a deadly accident involving eletric showerheads. The wire gauge and breaker are highly regulated when you build a house.

I like how you're concerned about other channels. Truly gentleman

ElectroBOOM: "If this is installed correctly by a professional..." Me: laughs in Brazillian

I just renovated the electric installation in my bathroom here in Brazil, and I had to run 6mm wires for the shower into a 32A circuit breaker. You definitely DO NOT plug these into a regular outlet.

I'm from Brazil. Here, most houses use an electric shower and accidents rarely happen. The showers reach 7,500 Watts and most of the time copper cable of 6 mm² is used.

Lmfao love how you casually destroy your oven and fix it.

"Ok let me do a simple demonstration using my stove." Dismantles it entirely in the process got to love that determination

Well I Installed and replace the resistance in a bunch of these back in Brazil. We do have thicker wires running for those, and there were some older models that the case was made of metal and would give you a little shock when installed improperly and touched. Even 110v house would usually have a second phase to run things like this in 220v, specially in the south where it gets really cold in the winter. Houses in Brazil are not made of paper like here so that helps with the not setting everything on fire as well. A funny comeback is that other countries are the brave ones for running piped gas everywhere and within their house. Either way I have never heard of anyone gettin hurt with these showers, and Brazilians alone probably take daily showers equivalent to the rest of the world together.

6:00 oh right, this was about a showerhead not a stove

He really needs to teach high-school kids. I would have loved to listen to him rant in a classroom

I bet his last words are gonna be “let’s plug it in”

As a brazilian, providing you install it according to the specs, I can tell you it's super safe and more eco friendly than gas shower. Also, pretty much every brazilian I know got a few electrical discharges from "suspicious" places, like when you go to some sketchy air BNB, or some hostel in the middle of nowhere, or some high poverty area. I've got a few of those myself from the shower faucet, and it's not "terrible". Not pleasant, but def not gonna kill you or anything. PS: Also in those sketchy places we would shower using rubber sandals to prevent that lol.

This is what i imagine a genius mad scientist IRL is like

ElectroBOOM: Safety First. ElectroBOOM: *nearly dies every episode*

Everytime he teaches us something, his apartment power goes out

I've always been freaked out by the exposed wiring over the shower heads here in Brazil. It's just kinda creepy to have that in the shower. Also it was common to be shocked when turning the knobs

Greetings, I'm Brazilian and really here in Brazil 90% of households use electric showers, and there are very few reports of accidents involving electric showers. Few residences use gas showers, in buildings and buildings it is more common to use showers with gas heating due to the number of residents, if they were electric showers the installations would not support such an electric current. Our electric showers range from 5,500W to 7,800W with very high currents. Our houses are prepared with their own installations and exclusive for this equipment, copper wires of up to 10mm² and circuit breakers of up to 50A are used to support it! Hugs!

"if it goes into your eyes or mouth it could really hurt" *"OKAY LETS TRY IT"*

“So I hate to say it but besides the *loose wires* and the fact that it *may set your house on fire* , it seems pretty safe” *i agree with your logic*

Can confirm... in Tanzania (240v) these tingle, even when installed by a professional who also dug up and replaced the earth spike.

We have two of these showerheads in our house. The first one was installed by an (unauthorized) electrician. It shocks me occasionally when I touch the faucet. I don’t like using it lmao. The second one was installed by my mom who is definitely not an authorized electrician either, but she still managed to make a better job with the second one. It does not shock me! Although the ground cable is definitely just hanging out in the air. It terrifies me still. Thanks mom!

People are usually shocked when they find out I'm a bad electrician.

8:24 *gurgle gurgle gurgle spit* AH I FEEL NOTHING

This man's sponsorship spots are so smoothly done and relevant. This is true content creation that I can respect!

here in brazil people only die with gas heated showers. never heard anyone who have had fatal injuries with electrical shower

LMAO. You are a gift to the world. You are educating us, but we don't feel like we're being educated, we feel entertained. That's a hell of a skill.

9:32 Installed by a professional...Yes...Yes... [laughs in brazilian]

The oven shorting on his wires had me rolling!

I’ve used those a couple of times and I get some tingles similar to pins and needles when getting near the shower head.

8:26 that is my motto for my entire life. every day i wake up, i gag and say "bleagh. i feel nothing."

Other people: "Installed by a professional..." Brazilians: Hold my beer.

This guy is awesome! I have to keep pausing videos, laughing too hard. I'm going through a rough patch , this is my therapy. Thanks so much. Stay well my friend

It's funny because these showers, especially from the Lorenzetti brand, are widely used throughout Latin America because of the low cost, I'm from Costa Rica and here at least 80% of showers are of that type. These showers are dangerous only because most people install them improperly without connecting the ground to save money on hiring an electrician. I myself have one well installed and the only problem is the durability of the heating elements, after 4 years it is common to replace them or the entire shower.

When I see this unibrowed almost bald man with a handsome face on my notification I click

Mehdi: "So if this is installed absolutely correctly by a professional..." We, brazilians: "Lemme look on youtube how to fix my shower without powering my house down..."

Loveeeeeeed your video. Brazilian and I used to have my house on 110V, so my Shower Head of Doom ran on ~50A. Usually in Brazil, the electric project of the house is designed to support that high amperage. But besides that, I have never heard anything about any of those catching fire, the worst case that might happen with those is poor insulation so you might get a slight discharge on the water valves. Nothing that a towel doesn't solve (Brazilian kids learn about insulation instinctively)

They are quite safe to run if you properly follow the code (which you didn't). In Brazil the way we set them up is by getting a split phase 220v dedicated circuit with very thick wiring just for the showerhead. You can't get shocked by the water and it is against code to wire it to a regular wall socket or without ground. You are supposed to use Wago connectors that can handle very high amperage and the shower head have to be set up very tall, cables should be unreachable and perfectly isolated inside the wall conduit (walls are supposed to be made out of concrete and not cardboard like in north america btw).

Keysight: Amazing new, affordable product. Circuit specialists: hold my multimeter

8:23 "I feel nuffing!" You and me both... you and me both...

i will say one thing in Brasil a ton of houses use electric showers and i NEVER heard of some one getting electrocuted in one of them even when its build in a shoty way

Commonly it is used 6 to 8mm wires alongside 50A 1 or 2-phase breakers(Disjuntor in Portuguese). Gas central heating is not very common in Brazil and the prices make it less common. Even though most of the houses that have central heating use gas cylinders, there are few locations where you can find gas pipes.

1:47 *Bold* of you to assume that i have brain cells.

You know when a video gonna be good when it's write "doom" in a electroboom video

I love that you acknowledged that your video might displace other good videos so you chose to give it a different title

Using an electric shower requires some care that we learned as a child in Brazil. The shower should not be close to the head; the temperature selector switch must not be touched while it is on; taking a shower using rubber slippers is recommended in places where the electrical installation is precarious; and there must be a circuit breaker just for the shower. Electric shocks in the bathroom are common, but they are usually minor. I believe that the main risk of electric showers is the fires they can cause. We already had a shower that caught fire in my house, and it has also occurred to me that I was in the bathroom on a day of hydraulic instability and the shower element turned on by itself, causing a near fire that I managed to prevent by turning it off immediately (if I hadn't been there seeing it, it would have caught fire).

I live in Brazil and never heard of someone being electrocuted in shower, even though most houses do not ground their showers. Always wanted to know how the hell it is possible. Great video!

_“hi, in my previous video about getting electrocuted in a bath tub”_

Mehdi is an absolute treasure. Thank God we have Mehdi to educate us on the fascinating world of electricity.

You mentioned brazilians, not knowing this summons us. Behold the upcoming swarm. May Tesla protect you.

6:38 this man has become so used to everything going wrong that he is fully confused when it worked right and didn’t explode.

we have those but it installed way higher, i'm 1,75m and I need to get on the tip of my toes to change the temperature, this way the water falls in little drops and not a continuos jet and therefore it's not conected to the heating element.

Boutta turn my bathroom into a HBIED with a shower head. Fun fact: in Fallujah, marines were finding IEDs hidden in shower heads, so that when the water was turned on, it would detonate. That's why the local forces and marines had to cut off the water towers.

"the voltage is not high enough to hurt you on skin but if it enters yours eyes or mouth it can be dangerous. Ok let's try it" LOL

You said those things could use an insulated heating element, but that's actually not possible considering how fast it has to heat the water running through it constantly.

Brazilian houses are made using powerful Wires in the bathroom to ensure that the electric shower does not have a problem with the wires not holding.Last month I installed my first shower and it didn't cause any problems and I don't know anything about wiring, and my house doesn't have a ground wire.

Tittle: "How safe is the shower head of doom?" Video: Mehdi playing with the oven for four minutes.

In Brazil we usually use the -240V- 220V (typo) version because of the lower wire diameter needed and most houses doesn't have any grounding.

FYI, Surface Element switch or also known as an Infinite switch uses a bimetal, that cycles the power on and off based on the current flow through the element, but the element always gets 200+ volts in any temp setting just percentage of on time. Bimetal is Between contacts L2 and H2 in your switch. If you look in hte back of the switch the bimetal is usually exposed and can be seen easily. L2 to H2 are the contacts that welded together in your video that you unstuck. That is the bimetal.

Electro boom I like every time when you say hi in your video it just starts it off funny😂

Says “ill pick a different title“ Used shower head of DOOOOOOOOOOM

"KUH-NOB" 🤣 Love your videos!!

"Besides that it has loose wires and may set your house on fire, it seems pretty safe" 😂

I remember having to use one in Guatemala for about 6 months. It was an interesting experience. Especially while wearing jewelry. Turning on the water was the easy part. Touching the knob to turn the water off is where the adventure was.

"it seems pretty safe" Unless neutral wire breaks. A great gift for a "favorite" relative.

Im brazilian and i must say i was always scared to use the shower in my mom's house because i was afraid id get a shock from the faucet xd

40 years here. Been taing baths with these all these years, at least once a day. Still alive...

"besides the loose wires and the fact that it may set your house on fire" but we do not use loose wires, instead in every home here, the shower have a special outlet (way above the showerhead) and they proper hight current circuit apart of the house's circuit, which helps with theses two topics "loose wires" and "set your house on fire" :D

Here in Brasil (HUE-land) we use these showers everywhere with no problems because: 1- the power grid of our houses are made with this kind of shower in mind (50+ amps). 2- we don't use them this close to our body, it's a hot country and we install our showers higher, close to the ceiling, the power outlet usually come from the ceiling, far from most people's reach. PS: our standard ceiling is 9~10 feet tall, again, hot country.

8:24 (waterboards self) "I feel nothing." *FBI wants to know your location*

had one of those in my apartment for like 2 weeks as they were still instaling the heater. It barely made water warm, I was so glad when I took it off

Brazilians have love and pride about electric showers. They are the main manufacturers of these devices, or at least that's how it seems in Mexican stores. In order to use one of these devices, you must have an independent power line, direct to the electrical box in your home. That line should use cables capable of supporting the maximum amperage of the shower. That line needs its own thermomagnetic switch and, preferably, an independent ground line. Please, an electrician is definitely required.

"1 minute on, 1 minute off, 1 minute on, 1 minute off" -> a.k.a. very low frequency PWM

Back in college, I helped a friend install one of these in his room. Neither of us have any knowledge regarding electrical engineering

In Bulgaria most of the people live in apartments with no ground. We have only two wires to each plug, so if you need ground for some application you connect the ground wire to the neutral. This works well, until something happens to the neutral, and all appliances with metal housings, become live. It is pretty common to have minor shocks when you touch the housing of say, the washing machine, because the neutral usually has some voltage relative to the ground your feet are touching.

Love you dude. I always look forward to your videos to get a good laugh! Thank you!

Imagine you click on this video and skip to 8:24 with no context 😂😂

I can imagine this guy's phone conversation with his wife: "Honey, why is the fire squad at our home again?" "Oh, I was trying to see if I could electrocute myself with a shower head. Turns out, no, it won't electrocute you, but it may set your house on fire." "Uh-huh." " Oh! And I got a new sponsor, too!"

I use this device to fill my outdoor pool in the winter cause it never gives up and I can relax in a cheap hot tub for an hour. Everything has it's use.

That is true! In Brazil most houses use the "Ducha" that can be adjusted between cold, warm, and hot water throughout the year! To provide the necessary heat, these shower heads all use 220 volts.

after the oven i forgot that the video was about the shower lol

Me: *searching "suicide shower head"* ElectroBOOM: *Top result* Also ElectroBOOM: "I will pick a different title, so the video won't show in the same search"

9:05 "and you know people, they may not connect the ground properly" I can assure you we connect ground to neutral properly.

yeah, I have used those here in Chile.. in rural places places mostly.. about 7:00 . it would trip, if they weren't usually installed in a way that bypasses the RCD... standard wiring is 2.5mm, single phase ac.. 😨

7:58 The spoon is offered by CircuitSpecialists

8:57 great rhyming!

Damn. Just missed the give away by 2 years lol. Thinking about one and ive been binge watching your vids, they are great thank you 😎 glad to see it in real world use

Here in Brazil they are in 90% of all houses!

8:15 ElectroBOOM: “When the water comes to your eyes or your mouth, it can really hurt” Also ElectroBOOM: *_lets try it out_* Its like he _wants_ to die

3:55 " i mean for around 200V AC, *throws in an ad* i mean $200 dollars.." this guy is the best.

I'm more baffled to learn that Joule heating is an alien concept for so many people.

I'm from Brazil, it's 2022 I'm 35 yo still alive and clean. One or two baths every day since I was born. My mother 80, still alive and dad 83, still alive, baths everyday too. Cheers from the electric shower country. I'm installed my shower and I'm not a professional BTW haha In Brazil we are born with the sambalêlê

"$200 dollars" it's pretty affordable, not in Brazil, that is far more than our minimum wage

"Besides the fact that it may set your house on fire it is safe." Thank you, sensei

Here in Brazil all pipes are pvc (the majority at least) there is a chance you get shocked touching the valve (I forgot the name of the valve you use tô open close the shower) if your ground is not set properly. Usually those things bust itself and you just have tô chance the shower head (or the resistance inside). Some time ago the shower head overheated in my house and glued on, that was the only problem. 10 days on 24/7. The electricity bill was double for 2 months (5 days in one month 5 days in the other, it consumed 1000kwh)

Although it doesn't seem like it, these electric showers are very safe nowadays (I say nowadays, because in the past, in the first electric shower models, the piping was all metal, so the risk of getting shocked when turning on the valve was high, and the the shower was activated using a disconnector switch and the risk of you turning on the shower while wet was also very high) they are even safer than gas showers, here in Brazil it is very rare for accidents involving electric showers, when it does happen, it is usually because the person forgot to turn off the circuit breaker to change the resistance, or else, for some reason, probably incorrect installation, it caught fire, on the other hand, every year when winter arrives, cases of people who died of asphyxiation due to monoxide are very common. of carbon that leaked from the gas heater,

Here in Brazil about 90% of the houses do not have grounding and we connect the ground wire in the neutral. edit: taporra tem BR pra caramba aqui kkkkk
