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.
Yeah, sometimes a little bit of dust in the wrong place can make all the difference.
The Omnissiah wills it.
i learned the same thing as a kid working on million dollar machines at a newspaper. the head maintenance guy told me just un-seat and re-seat all the connections, that fixes most problems
As someone who spent over 10 years in the Navy who was allowed to assemble/disassemble a few more electrical components than I probably should've due to my electrical background, can confirm. "Mechanical agitation" is a real troubleshooting step, even if the SOPs don't explicitly say so
Appliance repair here. Yeah that’s happened for me too. Just unhooked everything, looked at the connections, and put them back. Magically fixed.
Mehdi is so selfless. He goes around the world to test electrical systems in tourist areas to make it safer for all while letting his own home become neglected with failing outlets. He is the true hero we need!

Gloves?! My god, that's the first time i see Mehdi wearing protective gear on his hands.
GLOVES!
If he made one mistake and it caught a glowing wire or caught fire somehow he would need to get skin grafts.
That stuff he used as "protective" gear, well that's literally liquid fire when it ignites, dripping, oozing, splashing is guaranteed. Especially if you handwave in a panic.
I still shiver at every move he makes even without overthinking it the way I just demonstrated, it's a miracle (oh and a lot of skill) he still has all his digits and original skin.
🥊
He did wear gardening gloves waaayyy back in the Graphite video (I think that's from 2017), but that didn't end very well for him😂 I'd recommend going back and watching that.
He should consider protective HEADGEAR..........Zap/ Shock/ Bang Head......Repeat.
For as often as Mehdi performs his GFCI tests, he ought to 3D print some sort of enclosure that would let him put his probes and resistor all in place ahead of time. Sure, wouldn't make as much of visual spectacle, but it'd be easier!
It's all part of the pagentry
as long as the enclosure features a ton of live exposed wire i agree
I strongly suspect most of the shocks/pops are added in post. 🫠 He's got a good schtick worked out, but he's intelligent- he wouldn't actually allow himself to be shocked by say, house current for example.
I bought a cheap tester which also happen to test GFCI.
I didn't have any protection besides sketchy grounding and GFCI in bathroom.
Bold of you to assume he know how to make 3d model and use 3d printer

Electrical engineers when they have to work on the most simple valve ever
Lol I never understood how people have trouble with mechanical devices. You can just look and see how it works, whereas electrical circuits are the ones with invisible operation.
and vice versa. I can understand a comple madness of springs and levers, but even a simple circuit requires me to engage 100% jf my brain...

No it’s often frustrating because you’re like why isn’t this piece of shit working so you take it apart, find nothing wrong, put it back together and it suddenly starts working again

When you disassemble stuff you inadvertently remove dust and debris that might have accumulated on the device that was most likely causing the malfunction. It's pretty common.

@@ijtsuken oh, I know it's a very valuable test as often it will tell something is wrong even before sparks/or smoke. Just funny that (at least on the cut he released) he started with that test, when often that is a second or third test after you've done tests before making power live, lol
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.
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.
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?
@@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.
Why unfortunately? You hated your GFCI job?
@@sadlerbw9install a higher quality device. Radiated emission susceptibility means insufficient design quality.

Here in Uruguay we have a saying: "En casa de herrero, cuchillo de palo" (in a Blacksmith's house, a wooden knife), so you get where I go with this. I always found that the greatest of professionals (specially the most creative) usually tend to be pretty careless about their own workplaces... Maybe because they know exactly when each plug in the house is gonna burst into flames, who knows.
Nice to learn it's said in Uruguay too. It's a very popular saying in Spain actually! It might be as old as time.

4:24 Obviously that's not how we check it. Always use the back of your hand to check the live before grabbing it.
Oh god didn't even realize what he did 💀
This video is giving me dad vibes. Mehdi is just so loveable and seeing him work while explaining things is just like my dad when I help him with stuff.
Taking something apart and learning from scratch is always so fun love seeing others do it as well it feels the most authentic and most constructive way to learn for myself at least
That basically means the test button does not simulate the ground fault but only provide energy to the tiny rail gun inside. No worry Mehdi you will be safe🥰
Yeah that’s super weird. In Europe RCD test buttons literally close a circuit between live and neutral outside the sensing coil (through a resistor) thereby directly simulating a fault.
i suppose its more likely that the closing mechanism will fail rather than the current sensing circuitry.
@@killingtimeitself but simulating a current imbalance will also cause the whole closing mechanism to activate as it would in a real ground fault, and it will also catch issues with the current sensing system itself
@@thebaker8637 yeah, obviously, either code demands that it only insure the closing mechanism work, or it's simply just not that big of a deal.
Using a test load would be more reliable though.
Most of the idiot light inspection tools have a GFCI test button that does an actual ground fault.
Knowing how it works is the first step you need to take before you can even attempt to fix it. But I generally agree, that sometimes disassembling something and then reassembling it can fix the problem.
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.
14:35 Why are You greenscreened at the last scene? 😂😂

Fantastic video! I was literally dealing with this same exact issue last week. I removed the faulty GFCI and pulled it apart (unfortunately I had to destroy the casing to disassemble it) and I saw basically the exact same hardware you saw. I figured out the solenoid coil, and disconnecting contacts, but I couldn't understand what was going on between the line terminals. Thanks to your video, now I know!
Was it riveted shut?
@@memejeff Strangely, the case was all plastic. There were 8 plastic tabs that kept it together, but unlike normal plastic tabs that can be pushed aside with a small screwdriver, they had been heated and formed after insertion to make it impossible to disassemble non-destructively. The only way to get past the tabs was to cut either the tabs (which didn't work very well) or cut open the holes they were threaded through (which was much easier, but way more destructive).
@@geraldalexander8093 wow. I have never seen something like that before. Shame that they made it like that. Sounds like a shockingly complex way of sealing it.
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.
Yes! I finally understand how gfci switches work. Thanks Mehdi
As a European, I find your plugs insanely needlessly over-complicated.
pov: your house is haunted but you are an engineer 1:20
Found your channel by accident, haven't watched you in years glad your still making videos subbed
Had similar experience with outside receptacles on brick house during high humidity. After much research and testing found that the bare ground wire when folded into box with receptacle was very close to neutral screw. Pushed ground wire neatly away from neutral. Fixed! The ground wire on your test rig is insulated.
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.
I was waiting for him to realize he did not fix anything, just disassemble and then reassemble😂😂😂 14:05

@@Okurka. As a general rule of thumb: No, we don't. The long answer is that it depends on your particular local distribution grid and your particular house. I have 15 A 240 VAC. Getting shocked by that will absolutely kill you if the current happens to pass through your heart. I have a friend who lost his dad from electrocution by simply cutting a live cord he assumed was not plugged in, without GFC.
DIY Vibrator from a power socket!!! Very nice!
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 :)
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.
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.
@@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.
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.
Damn, I didn’t know Mehdi was specialized in Mechanical Engineering as well.
Thars fascinating! I've always wanted to know the inner mechanisms of GFCI
Man, I love bouncing back to this channel

I have observed a Strange Failure mode on my household GFCI Socket (just one).
The socket is receiving power from a light which has a dimmer on it. Stupid, I know.
I noticed the GFCI Failed to Activate when the Socket Voltage was down to 87V rather than the expected 110V.
I don't know if I am correct in this however if I am it would seem to be a very dangerous fail mode.
Ive never seen that before, A GFCI wired after a dimmer switch. my guess would be that either the triac in the dimmer which is trying to reduce the voltage is playing havoc on the sensing. or perhaps the sensing circuit inside wouldnt activate at voltage that low. or even maybe it was active and trying to break the circuit, but the 87 volts instead of 120 was making the coil too weak. knowing what i do about dimmers. Which admittedly isnt too much but i do know that not only do they reduce the voltage but they also reduce the Hertz. so instead of 120 at 60Hz it would have been 87 at like 35Hz and maybe that was causing issues. who knows, thats an odd quirk and probably should be addressed. but I doubt anyone ever would since your never supposed to wire dimmers to anything other than inbuilt lights, as far as i know your not even allowed by code to wire dimmers to non GFCI outlets or at least have to make it plain that that particular outlet is on a dimmer since most dimmers can only handle like 150 to 300 watts of power and if someone say tried to bung a space heater at 1500 watts into the outlet it would absolutely burn out the dimmer circuit and potentially risk a fire in the wall.
@@compzac Lamp dimmers do not alter the frequency (hertz).
Agreed that feeding any outlet from a dimmer is stupid and probably illegal.
... Some GFCIs don't cope well when connected to appliances that halfwave rectify the mains. The DC offset component (current only drawn on one side of sine wave) creates a semi saturated state in sensing transformer and messes with tripping. Possibly your dimmer only uses half the sinewave at certain voltages?
Your example with a dimmer is unreasonable (it's a code violation) but a related situation is a loose neutral connection. That would lead to the GFCI's circuitry being unpowered even though the hot leg of its output is still connected. Touch hot and ground and you'll get shocked but it will never trip. All standard GFCIs share this issue. Some specialty GFCIs require power to activate their output and thus are immune to this problem.
@@leybraith3561 Half-wave rectification of the output doesn't affect the sensing coil. If there's no ground fault there's no magnetic field and thus no saturation. The issue comes when a fault current is _purely_ DC. Even if the _fault_ is half-wave rectified there is a major AC component and it will trip.
