I was a US Navy mechanic for 20 years. I very often found that when something was malfunctioning, and I took it apart, didn't find anything obviously wrong, and put it back together, it was magically fixed. I think it's because in the process, I accidentally cleaned out whatever bit of debris or tightened whatever loose thing was causing the original problem. Gremlins broke it, gremlins fixed it.

[@rpercifieldjr]

Unfortunately, I have extensive experience with AFCI's and GFCI's. Nuisance tripping of GFCI's is sometimes associated with inductively coupled noise onto the feed lines, such as a compressor starting for an AC or Refrigerator. Another source is that the GFCI is very sensitive to high frequency conducted emissions and will trip. While your Tesla Gun does have very high voltages, they may not be at a frequency that is worst case for the breaker you have.

[@mb-3faze]

Although tempting to put a GFCI socket on a refrigerator it's usually better not to because that last thing you want is for the refrigerator to de-power (and de-ice) without you knowing. Also, invariably the socket is right behind the refrigerator making it a PIA to reset it.

[@sadlerbw9]

So, what can be done in the case of noise on the feed lines? Do you just have to try different outlets until you find one that is less sensitive, or can you stick something on the input lines to suppress the noise?

[@rpercifieldjr]

@@sadlerbw9 Currently there are multiple efforts to define at Agency Level (i.e. UL, IEC, NEC, etc) a way to improve performance of these systems in the real world. One example was when the compressor on a refrigerator started, and the inrush current occurred, this inrush would impress a current in an adjacent wire for the bathroom, and the GFCI would trip. Not the GFCI for the Kitchen but the bathroom. In evaluation it was shown that the feed cable for the bathroom ran in the same holes in the studs that the kitchen did. it was over 12ft of running in parallel. The solution was to replace the breaker panel GFCI breaker with the outlet version in the bathroom. This stopped the impression of a differential current in the wire. This issue affected about 60% of a 600 unit apartment complex. It is very complicated and technically challenging to resolve. Also each case is different. You can look for the offending signal source, but may never find it. Many times it requires changing the outlet GFCI and or AFCI to another manufacturer to get a better noise immunity.

Thank you for this, I often get asked about these in my line of work and haven't really had an opportunity to take a working one apart. I work in this weird little niche bridging electrical and electronics, specifically dealing with high voltage surges that blow up electrical and electronics in people's homes, mostly from lightning strikes and damage from the electrical grid. These fail are many ways and you let me understand how they basically all work. One is obviously catastrophic where plastic blows out and electronics are burnt. But they also will sometimes not reset, sometimes they will not hold a reset, sometimes the button is permanently and firmly depressed down, and sometimes the button will be press-able but it won't do anything.

[@SirWuffleton]

It's funny that I just had a faulty GFCI of a different brand that was several years old - It would randomly pop when a particular low-power server was added to my homelab rack. Even after swapping the guts into a new chassis with a known-good power plane at the behest of "voltage out of range" diag messages, it'd still pop after 1-2 hours. After reaching wit's end after many tests the fix for me also was swapping it out for one that looks like your replacement! Whether it was a failure due to a design flaw, years of semi-high (5a-10a @ 120v) constant load, or some weird transient noise that an additional (and extra-sensitive) protection feature didn't like my setup, I'll probably never know. All I can say for certain is maintaining sanity is definitely worth the $20 for a new GFCI when nothing else can isolate the outlet, wiring, or devices that it feeds as this isn't a completely uncommon failure mode for old GFCI outlets. They don't last forever!

@@memejeff Strangely, the case was all plastic.

8:20 oh god, I had a GFCI in my kitchen die in such a scary and violent way that I thought the house was burning down. Heard this ungodly buzzing noise and then a loud pop like a firecracker. Kitchen smelt like burnt wiring, half the outlets were dead, half weren't. At the time I had no clue. Panic-called electricians and they came out first thing in the morning. They diagnosed it to the GFCI. After they replaced it, I took the old one apart like you did and found that the little coil there had a visible break in some of the windings, and under an electric microscope, I found insanely tiny bits of copper everywhere. So I guess something inside mechnically failed and that coil smoked itself until the copper melted and formed a break that caused a violent short/arc.

[@compzac]

It could also have been that the coil was trying to break the circuit, but had physically gotten stuck, you can see in his video when he was playing with it. it was buzzing angrily and started smoking. in my experience with GFCIs the test resistor and that coil are not meant to see full 120 volts for very long. they will often fail. usually spectacularly with pops and electrical smells and the mysterious grey smoke.

[@eDoc2020]

@@compzac That's the most likely scenario. It was trying to trip but for whatever reason failed to shut off the power. That's probably part of the reason they say to test monthly, that ensures everything keeps moving freely.

@@compzac If that was the case I can't imagine why. At the time nothing was really using that circuit, and after they replaced it with a new GFCI and I turned everything on, nothing ever tripped.

Hi Mehdi I remember your video from a while back on peltier devices when you said you didn’t understand the reason for how they work, I think I finally understand it. I think that the peltier effect ( cooling effect upon application of electricity) is due to the conduction bands of 2 different materials being slightly different from each other, We can try thinking it through with the example of an electron(e-) moving from a lower conduction band to a higher one. So if an e- is trying to move from 1 material to another, it will need to jump to a higher energy level, Total energy = Kinetic + Potential energy. The Potential energy gained by the e- has to come from the previous material’s particles. But since the inner shells of the previous atom should already be filled, none of them should be giving out energy by decreasing their energy level, thus only kinetic energy is loss. Meaning a very small temperature drop would be measured per e-. This is just from what I managed to read online, I do not have much knowledge about conduction bands, but hopefully this helps :)

Who else wants a Technology Connections / ElectroBoom crossover?

[@LittleDancerByGrace]

MEEEEEEEEEEEEEEEEEEEEEEEE

[@tlhIngan]

Ground is not needed for these devices. In fact, if you buy them, there will be a sticker that says "No Equipment Ground" which you put on if the socket is not grounded. Yes, it is code legal to replace a two pin ungrounded outlet with a 3 pin GFCI outlet, and it's safer that way too.

[@MaxCarponera]

Suggestion: The tripping solenoid composes a tank circuit with some spurious capacitance on the circuit, making it resonate in a certain RF frequency that coincides with some thing around your house. Might be some radio station or a neighbour using a blender. Alternively, the current sensor can be the one who picks de RF.

[@civildisorder]

This scratched the itch I had as a kid to take things apart and (pretend to) understand how they work. Also appreciated the realization of not fixing the original problem after going through the effort of putting the whole thing back together again.

[@lollermann]

10:53 Nah dude I gotta buy you a dinner first

[@CM-kl9qh]

As a Control Engineer there were many times a re-assembly would make the problem go away for a while. The preferred scenario was for the component to fail outright and get replaced. An intermittent was the biggest pain because you’d spend hours trying to find it!

[@elvara872]

From an EU perspective, it's actually crazy to see that only on the outlet in the wall and the size of the circuit just to protect 2 plugs. What I have in the fuse box here works both as a circuit breaker and a GFCI to protect all the outlet in my place and people at the same time. It's crazy how different it is in NA compare to here. I would be so lost trying to work in canada or US.

[@kratz9]

GFCI breakers are a thing in the US. Code specifies what needs protection, but both methods are acceptable. Typically only 'wet' (bathroom/laundry/kitchen/garage/basement/outside) locations. One main advantage of the wall plug GFCI is that the state is visible and it can be reset from the point of use.

[@RonParker]

@@kratz9 Current code requires AFCI in most living spaces, so a lot of new construction puts all of the protection devices in the panel. Personally, I prefer it that way, because with circuits shared between multiple rooms, the receptacle with the AFCI/GFCI might not even be in the same room as the point of use, and which room it's in is entirely up to what substances the electrician who installed it was on that day.

[@mernokimuvek]

Actually, in many european countries it is no longer accepted to use asingle RCD for the whole house. You must use more to avoid loss of power everywhere and several minutes or hours of profanity if a ground fault happens.

[@jpol3808]

I showed some big shot electrical engineers that you don't need to have a ground wire at the outlet box to have a GFCI function properly. Not a single one could explain why... But then neither could I, but at least I knew it didn't need the ground wire. You just explained why that is. The ground wire has nothing to do with it's functioning. It's there only for the short circuit protection of that device. The GFCI will still trip as necessary without the ground when it senses the imbalance between the neutral and load wires. It actually. Ground actually has nothing to do with it's operation, as it's name has caused many of the brightest electrical minds to be misguided on how it functions! So install them even if you have no ground wire because they will still work just fine. Just make sure you label it... No ground wire so people know! 👍

[@racker6081]

at 14:27, for the first time ever since I started watching you, I got startled when you got shocked XD

[@tharii314]

This one, Firefly Lantern, Capacitor BOOMer prank, ChatGPT vs Mehdi, the Turkish investigation video and soe few others seem to have a different approach of building thumbnails and I really appreciate how energetic and mesmerizing they look and feel. But at the same time, I understand the legacy of this particular channel is bound with simplicity and the process of learning from scratch, with limited choice of fonts that are looking pretty basic.

[@janvesely1938]

4:30 Buy yourself a headlamp.

[@johnfrian]

Impressive, going from 100% confusion to explaining how it works in an understandable way!

[@Ali107]

13:07 *THE ONE PIEECE!!!*

[@Jim_100]

THE ONE PIECE IS REAAAAALLLL

[@AltafKhan-qd1tk]

I'll be the pirate king

[@prabalkumarsamanta8333]

'Mechanical Mumbo jumbo' is probably the most annoying thing that every electronics Engineer has to face in case of breakers or any switching assembly 😂

[@andrewparker318]

Mehdi, we in the community have so many ideas for projects we can do! Just give us a heads up you will be making a LATITY video and then we will repost all of the ideas we have been submitting on the subreddit over the last few years! Otherwise if you just react to it without warning, you might only see terrible memes or things of that nature

[@xuesco2210]

Was watching some ghost hunters recently and thought I'd love to see Electroboom take apart the ghost hunting equipment and do tests on what sets it off.

[@BeAwareOfElectricalHazard]

He is the most interesting science KZbinr I've seen

[@tom4ivo]

You took something apart and put it back together, and there were no extra parts lying around? Truly a god among men.

[@wigglesfourthree3390]

14:28 way to test the GFCI, made my arm jump. Mostly due to muscle memory and feeling your pain as you jump. I hope to meet you someday so you can hit me with your wand. Remember kids, you don't need to FEAR electricity but simply respect it.

[@ray.bonanno]

Can you do a video debunking “Grounding Mats”? I got an ad for one and I don’t want to be on this planet anymore. Especially after seeing there are hundreds of supportive comments 😭 And most content about them is about how great they are!!!

[@mikethor009]

A bit light on ZAPs this time. But i always love watching your videos.

[@bahamutbbob]

We need a collab with Technology Connections to learn more. Through the magic of having two hosts!

[@mohamedmergueb2180]

IF TONY STARK HAD MEHDI IN HIS CAVE BOTH OF THEM WOULD BE DEAD

Stolen 🤓☝️

[@mohamedmergueb2180]

Yup

[@kyrollos0208]

Why lol?

[@ThatJay283]

8:05 the coil there is the solenoid used to disconnect the circuit when a short is detected. it starts smoking because normally only gets powered for a very short amount of time

[@ashwalker1]

Your outlet looks really Sad 😧

[@docsnavely1010]

This is the best explanation/demonstration of a GFI outlet that I've ever seen or heard.

[@Awais....]

2:00 😮 😮

[@carlosjuniorfox]

The proms are easily touchable when live, and energized screws on the sides when you disassemble the outlet and GFCI at the outlet instead of the circuit breaker. The North American outlets are an atrocity. In Brazil, our outlets are recessed, so you can't touch the proms while they are energized, the outlet screws are on the back of the outlet protected by a plastic cover, and hard to touch.

[@suspense_comix3237]

Damn, I didn’t know Mehdi was specialized in Mechanical Engineering as well.

[@JCWise-sf9ww]

Mehdi is a brilliant wrecknician to show us the insides of a GFCI! Have you ever heard of a GFCI, simply tripping sometimes when plugging in any appliance? Well we have several GFCI outlets in our kitchen that just do that. I replaced the worst acting one where the microwave is plugged into and that fixed the problem. The people who had the house, before we bought it, must have installed the cheapest GFCI they could get.

[@joe125ful]

3:49 Exactly! EU standard for win. 9:27 Brutaly owercomplicated...

ElectroBOOM is like magic nobody understands t but loves watching it.

[@amritdas-zw9bu]

In india : if you have no protection, you are the protection 😎

[@sypernova6969]

Mehdi, that was reallly cool. very well explained, and the mechanical nature makes it very easy to understand, congratz on putting it back together, btw. thanks!

[@duyunodawey6371]

It's so wholesome that electroboom still uses his daughter's piano playing as his background after all these years

[@ThatJay283]

2:55 i did some extra calculations to figure out whether or not the resistor would have gone up in flames :) the video was too blurry to tell whether the resistor was 22kΩ or 220Ω, but if it was 22kΩ it would draw ~0.055A or ~0.65W. if it was 220Ω it would draw ~0.55A or ~65.5W :D

[@doomslayerclout]

Probably 22k ohm one
