I didn't learn more about humidifiers by watching his humidifier videos, except for the one about the personal air conditioner that is not an air conditioner. But I still feel it's educational, because it feels to me that Alec is incredibly good at communicating. This is something I've struggled with my whole life. I'm getting better, but I'm not to Alec's level. It's also fun to watch someone who is so clearly excited about topics as he is. My colorblind brother spilled the beans about brown before Alec was born. I'm not sure how old he is exactly, but he looks like a teenager in his 2013 videos. My brother struggled and failed to make bright brown back in the 1980s. Brown is one of the colors my brother sees well enough (so long as he's not trying to distinguish it from green), but he got my opinion on it because I can see color, I just got my fashion sense from my colorblind brothers. All of that said, I've watched a lot of his other videos as well, and, yeah, everything else, I went in thinking "I know this topic" and came away knowing more about it.

@goodun2974 3 роки тому

Any GFCI-protected electrical outlet in your home is a good test point for whatever older, perhaps vintage, electrical or electronic devices you might have decided to plug in after they sat around for years unused or that you had picked up at a flea market or whatever. Tube/valve type guitar amplifiers and hifi amplifiers are a particular case in point; these often have the audio ground and chassis coupled to one leg of the power cord *through a capacitor* , for the purpose of using the neutral wire as a pseudo "earth ground" to the chassis, in order to reduce audible hum and buzz. If the amplifier hummed, you would simply flip the non-polarized power plug around the other way and hopefully lessen the noise; or if the device already had a 3 wire grounded cord, there might be a switch on the back to select the ground polarity and you would set it to whichever position reduced the noise. The problem is, 60 or 70 years later those capacitors often leak voltage and so you might find some AC leakage current on the chassis of the amplifier, and also on the guitar strings and metal hardware of the guitar. However, plugging such a device with a leaky "death cap", as they are often referred to, into a GFCI outlet will immediately trip the built-in breaker and alert you of a dangerous situation.. As I have noted, vintage guitar amplifiers pose a special problem and should *always* be converted/ upgraded to a grounded 3 wire polarized cord and plug, with the death cap removed.

@10p6 2 роки тому

Nice. For those who do not know, they make GFCI with Audible alarms, so if you have a fridge or something connected to one, it could save you a lot of money if it trips.

@ImDemonAlchemist Рік тому

I mean, the only reason he's able to do this without sponsorships is because of Patreon, which is essentially just him being sponsored by his audience. It's not that different, fundamentally. I feel like demonizing taking sponsorships is counter-productive, especially considering that that's always been how educational content has been made. PBS is (or at least was) often supported by brands that then got a shout out between programs. Most other educational content in the past was supported by massive companies that could afford the cost. Not every creator feels comfortable taking money directly from their audience for what they do (which I don't really get, but it's their choice). There's nothing wrong with accepting sponsorships to support your private endeavor, especially if you only accept ones that you actually believe in.

In Europe, all safety devices are usually centralised, and it has been years since these elements were allowed to be placed outside the control panel. Normally we call it a differential, and we have them calibrated to 30 mA. (30 mA (for full circuit, not for one plug) and 230 AC volts, of course.) As for the circuit-breakers, they are the same but in a panel, they also protect against overcurrent and short circuits.

@corneel25 5 років тому

I think it is 30 mA for bathrooms and 300mA for general circuits

@pedroseoane 5 років тому

15 mA or 30 mA. If you exceed 30 mA in losses you need to split the circuit. (In Spain and in houses, not industrial this is another thing). More than 30 mA will kill you... this is the reason that forces you to split the circuits in 30 mA max possible losses. In any situation will stop you to death ;) Maybe in Belgium is different don't know...

@Hans-gb4mv 5 років тому

In Belgium it's 30mA for moist locations (like bathroom), 300mA for dry locations and if you go extremely wet (submerged) it should even be 10mA. In dry conditions you should be able to survive a very short jolt of 230V/300mA but under the right conditions even a 230V/30mA jolt can kill you

@PerMejdal 5 років тому

In Denmark 30mA RCDs are required on all circuits up to 20A (those above are used for distribution). It has been a requirement for new houses since 1975, and in 2008 it became a requirement for all installations. Even those that where legal when they where made. Non-private buildings are required to hire licensed electricians to test the RDCs every year, who uses equipment that measure that the RCD triggers fast enough.

@weeardguy 5 років тому

NO WAY! Wow. Just wow. I'm an electrician so I know my way around Dutch electrical wiring and know a bit about US-wiring and electrics, so I didn't thought I'd see something new in this video.But I NEVER knew there were RCD's built into wall-sockets. And just when I thought that was all, you started talking about appliances with RCD's mounted INSIDE the plug! To talk about these devices: In the Netherlands we tend to call them 'Aardlekschakelaars', literally translated you end up with something like 'Earth-leakage switch'.Though it indicates it does 'something' with a leak somewhere, it's hard for many people to understand that the safety-ground wire (which we just call earth or PE in electricians-language) has nothing to do with the RCD itself: it only senses that there is current leaking somewhere, but as it's not returning to neutral, we assume it's leaking to earth. And about the place where these devices sit: it's common in the Netherlands to have these in the service-cabinet (metercabinet as we like to call it).Indeed, it can be hard to find the cause of the leak, but that's also some common sense: just unplug everything on the same group (for as far as possible) and start replugging until the RCD trips and there's your fault. Garden-lighting is notorious though for moisture and causing random tripping of the RCD and because you have to open the switchboxes in the metercabinet, most people don't think about that possibility. We got our metercabinet renewed last year. We got PKN6 RCD's from Eaton. Big downside from these is that they don't indicate the kind of fault, whereas the devices from ABB I use on a daily basis at work, the DS201 series, feature an extra indicator so you know the type of fault that occured.An overcurrent just trips the device, throws the lever down ánd moves a green 'signal' in a small window just above the lever.Resetting it makes the green signal turn red again.A ground fault however, does all of the above, but also shoots out a blue indicator in the middle of the handle, indicating the device has tripped because of a ground fault. In Belgium, the usual name is 'Verliesstroomschakelaar' (literally translated: 'Current-loss switch).

A good rule of thumb for figuring out which device set of the switch is to unplug the last thing you touched, re-enable the switch and try again. Also in Flanders, the metercabinet is often called the "plombkas", literally the "kast" ('cabinet', the t isn't articulated nor spelled) where you put the "plombs" ('fuses', the b is also not articulated but appears in writing), which I presume comes from the French word for lead, i.e. what the old style fuses that melt were made of.

As an electrical engineer and musician, if you only knew the dangers... Your electric guitar's safely grounded, you'd think. Untill your lips touch the phantom powered mic, burning and blistering your lips. Yup, that was a "safe" voltage and current, but boy does it hurt. How to prevent? Don't ground your amp. Also, imagine: outdoor gig, rainy, foggy or damp weather. Got a wall of marshall/vox/*insert favorite flavour*. How safe do you think it is? Well, of course it has a transformer, so high voltage is separated from line. But not the energy. And where does every ground fault go? You didn't ground your amp to not be shocked by the mic. So every fault goes through anything else grounded. Via your guitar strings, through you to the ground you are standing on. And this was just one example...

Very interesting. At my house, there are non-GFCI outlets and various light switches that are daisy-chained off each other into God only knows how many directions, including hot lines to one thing and the neutral to a different thing. At one time, the codes allowed for such things. No idea which plugs/switches are on the original leads and which ones are the daisy chained ones. Keeps things interesting! And about two-thirds of the house is on a single breaker (although, to be fair, we've made it this far!).

@sguttag 3 роки тому

Excellent video. One thing I'll add (well...recommend)...particularly in Kitchens for the counter receptacles. Don't string them (don't use one and then wire additional receptacles, as they are designed). The 5mA current protection is total and if you are cooking some masterpiece that has the mixer, toaster, blender...and whatnot all going...these devices are often "reactive" loads that will have an influence on the current and timing that can cause a false-trip. Spend the extra money and let EACH receptacle be its own GFCI and you will never get false-trips again but be every bit as protected. In the USA you can (and in some cases) do get breakers with GFCI (and pretty much all circuits are now AFCI...different subject). Depending on what is being protected and where your breaker panel is, it would be a big annoyance to have to trundle down in the the basement/garage or wherever your panel is just to reset the breaker for this sort of trip. This also comes back to the more stuff you have plugged into the circuit and the longer the cable run is, the greater the likelihood of a false trip becomes (that long wire run to the receptacles actually consumes some electricity to heat up the wire too and you don't want that counting against you on your 5mA. Lastly, it was quite informative that internally the receptacle you showed has 20A contacts though a difference in the two models you didn't present is that a "TR" is going to also be Tamper Resistant (has the little doors to prevent kids from sticking things in). So you might get a price difference there though yes, 20A receptacles do tend to be notably pricier than their 15A counterparts.

@noahmccann4438 5 років тому

Excellent video, and I’m glad you touched on the differences between this and a breaker - I made the mistaken assumption that they were the same kind of thing, except that the GFCIs might be faster in their response. I’m glad to learn the truth though. I’ll also be sure to test these more regularly now that I’m more familiar with them. Good public service announcement!

@NickStallman 5 років тому

That's something that confused me about this video, in Australia/Europe/elsewhere, the GFCI/RCDs are integrated with circuit breakers so they have additional protections. E.g. if there is a large amount of current being drawn when it trips, our breakers can handle that but I don't know how the American GFCI's are supposed to handle the flash over.

@seraphina985 5 років тому

+Nick Stallman If I were to hazard a guess I would assume that the US outlets are designed under the assumption that they are protected by a 20A breaker and thus built with enough heat dissipation capacity to cope with the overcurrent for as long as it would take the breaker to respond. For the most part the breaker will be faster the higher the current so it's relatively consistent the amount of energy it would need to handle. I say relatively as of course extreme edge cases will destroy that such as suddenly being exposed to multiple megavolts such as in a lightning strike chances are that would indeed fry the GFCI and most of the electrical equipment attached to the circuit.

@captain150 5 років тому

In the US any circuit that has a GFCI receptacle will ALSO be fed from a circuit breaker, either 15A or 20A and so the circuit will have short circuit and overload protection as well. He didn't mention it, but there are GFI breakers in the US as well. These devices combine short circuit, overload and GFI protection in a single unit and protect entire circuits...identical to RCBOs in Europe. It's just less common to use GFI breakers rather than receptacles.

You can buy GFCI circuit breakers in the United States, they just aren't as common. They are easily found at Home Depot or Lowes and they even make ones that have a dual function of AFCI and GFCI. AFCI is also available in GFCI style receptacles too with some also being dual function with GFCI. AFCI is now required on almost every circuit in the house (in states that have adopted the latest electrical code) including ones that have previously required or have not required GFCI protection. You should do a video about how AFCI is different from GFCI now.

@ianbelletti6241 5 років тому

44R0Ndin. AFCI circuit breakeres have gotten better at detecting actual arcs instead of electronic noise.

@DenebTM 5 років тому

These things are just centralized in European homes and active on all the wiring. It makes them a bit more of a pain to reset if a fault occurs, but safer overall imo, because you don't have unprotected outlets, lamps or whatever else in your home. And since they do have to be checked on every so often to see if they still cut the power quickly enough, a single one in a centralized location is much easier to keep track of than potentially a dozen or so throughout the house, and cheaper to replace if it does fail. Edit: I see now you brought this up in the video, and you bring up some valid points why having these things decentralized can be advantageous, the ideal solution would probably be somewhere in the middle, like having one for each room and etc., but all accessible from a central service panel. Just my two cents on the matter.

I assumed it literally monitored both leads individually and compared them. It’s so much simpler than that! It’s actually genius in its simplicity!

The neat thing about modern GFCIs is that unlike old ones which can lose its protection over time and essentially revert to being a regular outlet, modern ones will have a lockout feature which permanently disables the outlet if the GFCI protection were to fail. This then forces people to replace the receptacle to have the the outlet working again.

@JohnSmith-ys4nl 3 місяці тому

Yes and the newer ones (since 2015) also must have a self-test function. They will test themselves every 30 seconds to ensure they are working. The owner no longer has to test them once a month (although it is still recommended). And as you said, the newer ones will lock you out when they fail their internal self-test, alerting you to replace it.

Allowing large leakage currents is fine for protecting the equipment, but doesn't protect people from shock. If you have a heating element that suddenly finds a path to ground inside your electric kettle, it trips. But if a person grabs both the hot and neutral, they can get electrocuted because a RCD doesn't detect this as a fault. The GFCI design adds this protection and is called a RCBO in the UK.

@okaro6595 Рік тому

That is likely because of TT earthing. I the US they use TN-C-S so on case if a fault hight current flows through the neutral and thr breaker trips. In TT the fault current is just a few amperes so one needs additional protection like a 100-300 mA RCD.

I test the GFCI's periodically. One day I, having lived there over ten years, I tested the one in the main bathroom, but for the first time leaving the radio still plugged in, which is a bit awkward, but I didn't want to miss a chunk of my program. And I didn't. The radio was still playing after the GFCI tripped. For over ten years I would have been electrocuted if whatever the GFCI was supposed to be protecting me from had occurred. Not really surprisingly, it turned out that the wires to the "line" were reversed with the wires to the "load," and the GFCI worked right when rewired. Somebody guessed wrong. Aren't electricians and inspectors supposed to know these things? Of course I seldom take the radio right into the bathtub water with me, so no harm done really.
