    Hey there! Correction time (and more thoughts!): THHN wire is what’s _inside_ the sheathing of Romex, which is actually classified as NM-B cable/wire. As in, the conducting wires are THHN, the whole thing together is an NM-B cable. Yep. So there’s that. Also, I want to be clear that of the problems we have, this isn’t a huge one. Generally, when things get hot because of overloading, it’s at the connection point and not in the wire. For instance, a lot of electrical fires start at the plug/socket interface either because the connection is poor, there could be corrosion, etc. And sometimes they can happen when nothing is overloaded! This is one of the circumstances in which arc-fault circuit interrupters can save lives. It may well be the case that very few fires are started because of the problem we’re discussing in this video. Especially since outside of certain high-draw devices, the risk of overloading the actual conducting wire is low in the first place. That’s why I am comfortable using them! That said, I remain perplexed that this is an issue we’ve let persist. Most electrical fires aren’t the result of a single thing; they’re a cascade of individually not-great circumstances combining to make a bad situation. In order to reduce the risk of fires, we’ve continually been making the not-great things less bad. That way an increasingly large number of bad circumstances have to align for a fire to happen. Simply put, I think allowing unfused 16 gauge extension cords into the market is a potentially bad link in the chain that we could probably do with cutting out. In fairness, it used to be much worse. 18 gauge (maybe even 20 gauge) extension cords were available many years ago, but we at least had the sense to make 16 the minimum as time went on. However, as I hope I’ve demonstrated here, that can still be problematic. Pulling 20 amps through that cord made it get very hot quite quickly.

      Well, here in Norway (230V IT or 400V TN C-S) electrical systems all use a lot both safer wiring, and brakers that brake both live and neutral wires, since if you should get a fault on the neutral, it can escalate quickly. We also on all newer installations use earth fault brakers that trip on maximim 30mA, and that in conjunction that our insulation to the outside ground has to be less than 1666.666666Ohm it makes it so that you, with a fault in your electrical system, can't get more that 50V in you before the brakers go off

      I'm glad you posted this but also I wish you would point out fima data on fire is a bad usage as water with salt creates a non resistive load on any device which can cause a fire within any device if it is not fused within the device. Also you failed to point out while we use AC power to deliver power most devices today use DC which requires a converter and a rectifier which would fail early in an over current situation before a load.

      @Kaleem Well, a higher voltage may be more likely to make you trip away but that doesn't make it safer. Being blown away is a danger itself (what if you end up falling downstairs or trip over another shocking device? ). If you haven't been instructed in Electric safety don't approach the inner parts of appliances. Technicians use safety measures and equipment. A good rule to avoid being caught and stuck to current is never have wires or current inducing things (even shielded ones) between yourself and the outer part of your nuckles. By default you should keep your elbows tight with your body and your fist closed. My comment may be wrong or unaccurate, so I guess Internet rules will summon the right answer.

      Also, most house fires are not from extension cords ironically. It's generally worn leafs in outlets (from plugs being pulled out and arcing wearing them down), and underrated toggle switches arcing and wearing down, and then eventually causing a high resistance point that melts the housing. Extension cords are far less likely to start fires.

      It's not really the problem you think it is. Instead of wanting to regulate the fuck out of life, instead why don't you proponent self-governance and intelligence. Furthermore, even shitty 16g lamp cord will survive 15A without starting a fire. I'd be more concerned with why you have stuff flammable at 150F sitting on a cord instead. Most carpets are not flammable unless subject to very high heat. Flame resistant carpets are basically the norm unless you're putting down turf/boat carpeting. The big issue with cords in walls, is they are in an air-isolated and often insulated situation. Cords in a bundle on the ground comes nowhere close. But even then, the concern isn't the wall catching fire, it's the insulation melting and then eventually arcing and THEN starting wood framing on fire (sheetrock is nonflammable). Saying we should have fused cords is stupid. Most people don't know shit and would just go, "oh this 7A failed but I can get a 15A and "fix" that problem. So you haven't fixed stupid AND just made life more costly and frustrating for the vast majority of responsible people..

    Off the cuff, I think extension cords are a bigger tripping hazard than fire hazard. The breaker protects an entire circuit, which typically contains more than just one outlet (or just outlets period), so unless the entire load is plugged into just one extension cord (and why would you do that????), a cord having a lower rating than the breaker won’t be an issue. Also, but just as importantly, self-heating is very bad inside walls, which don’t get any airflow or have a lot of space. The body temperature extension cord around 9:00 is not close to reaching either the insulation rated temperature or anything resembling a fire hazard. (As a point of comparison, Romex is often rated to at least 80C environmental, meaning that insulation can and will get even hotter under full load). Wires in walls are also run together (so a wire gets hot from the wire next to it) and are longer (order of magnitude, maybe) than an extension cord. All of those together mean than you can safely pump more current through a wire when it’s short, on its own and in air (ie an extension cord) than you could if it was long, with other wires in an enclosed space.

    Interesting caveat when it comes to industrial/commercial lighting. Luminaires are connected to the branch circuit with their own flex cables, that cable is selected depending on the ampacity of the fixture. So, this is 1 location you will find a permanently installed flexible cable with a lower capacity than the circuit breaker, the exception is given because it is a single known load hanging up in the air but is still fascinating.

    My first thought - the reason it's so important for you in the US to protect the house wiring from overload is that your walls are made of wood... Here in Britain, my walls are brick. I'll be extremely peeved if the house wiring should melt, but it's not going to set anything on fire. Second thought: Britain has been 200- 240 volts for a long time now, with varying, but increasingly safer plug and socket systems. The first ones I can remember were Wylex then BS546 before we all settled on BS1363 which is incredibly well designed and one of the safest plug-and-socket systems I know of. However, I have a suspicion that 240V 13A as a standard for receptacles came into being because that allows you to have a 3kW electic kettle, an absolute necessity for making tea.

    AWG is a really really bullshit unit. I have no clue why you never moved forward to a cross-section based measurement, even if it was in square width-of-a-thumbs (I think you call that "inch") This being stated, good video BTW, where the lesson also applies to us Europeans who also can buy some crappy 0.75 mm² extension cables. And we have that stupid "Schuko" plugs that don't allow for a fuse to be applied since they have no polarity assignment between the life and ground wire. So if you put a fuse this could be randomly on the life or ground wire providing you with a fry potential on an obviously cut-off device.

    Ring circuits... What that's all about.. 2.5mm (=~14AWG) carries approx 16A in a reasonable length... Ring circuit using 2.5mm carries up to 32A. Same (cheapish) cable much thinner than your 6mm (10 ish AWG) and easier to work with. Also if a connection goes bad, you don't lose the circuit - the big downside of course is that in that situation, a near capacity load could overheat the remaining cable, thus negating the point of a breaker. Ho hum. Oh.. and yes. 120V IS intrinsically less UNsafe than 240, but a given load will draw twice the current with attendant heating issues and a few 10's of mA across the heart from 120V can still just as easily stop afrementioned blood pump.

Your ideas about the power cords infusing are nice but they suffer from the same problem the overall problem as as well and that is it only fixes things going forward it doesn't do anything right so active for already in place items. Do you think people will buy new extension cords? No, of course not sure they will buy better ones where they buy new ones but that doesn't replace the ones that are out there are on the subject of things already out there what about all the homes built before current building code or built before the building code before that... Or built before the building code before the building code before the current building code?

    I would like fire department personnel be more educated before they open their mouths. I was running a test of a large number of devices in my shop area at the manufacturing facility where I worked. I needed to power 100, approximately 2 watt devices to gather data on their performance. I did it with a wheelbarrow load of cheep multi outlet cords dasiy chained. It just so happened, by coincidence, that the fire department was doing their random industrial plant inspections in our complex that day. When they entered my shop area they just about blew a fuse. Pun intended! "You can't do that and you have to shut that down immediately. You're going to start a fire. You have too many things plugged into the circuit. You are overloading the circuit!!!" I tired to explain the blatantly obvious to no avail. I said: "It is not the number of devices that are connected that matters. It is the total amount of power that is being consumed". Need I elaborate any further? I could not get the point through their "My mind is made up, don't confuse me with the facts" mentality.

    Interesting comments and wonderful points made. However I do think it's important to note that modern circuit breakers in the United States are only good for 80% of their rated load. This means that many 16 gauge and 14 gauge extension cords could potentially be protected if overloaded on 15 and 20 amp circuits. They still make 18 gauge which was certainly still be a problem. I really like your idea about having fused extension cords that would protect the cord from exceeding its physical limit. Great video.

    I live in Italy, and one fire, and one "almost fire" which both happened to my family or some relatives, both happened because of extension cords and/or "plug splitters" (like this one: ) . One "unsafer" part of the 120V system is that to operate your appliances you need much higher currents, therefore more risk of overheating, etc. In my house each circuit has (now) its own GFCB , and I have 400V three phase power supply (not normal in Italy), but i feel much "safer" than anywhere in the american continent... In Germany having 400V three phase in your house is the normality. Personally I don't like UK plugs, which were designed to fix a flaw in their electrical installations; also, UK plugs are perfect as caltrops, if you walk around your room with bare feet... I like "german" plugs a lot, more robust and safer than italian ones, and probably the french ones would be even better (since they can be polarized).

    The average Jo can't be asked to do the basic math to work out how much stuff they can put on a particular gauge cable, There is no way I'd trust them to replace a fuse with the correct speed and current rating. Jo is going to get sick of replacing it and wrap it in aluminium foil, leaving the cable forever a fire waiting to happen. People are idiots. Circuit breakers only please.

    Those people complaining about that “language quirk” are probably not very well educated in English. It’s pretty clear in English that adjective (safer) does not imply noun (safe). It’s the kind of language mistake Fox uses intentionally to obscure meaning.

    But it's not that a big deal! Technology is here! Like when i need a new extension cord, i always look for ones that has shock protection built in! That's not a super new tech and not too expensive either. I had few extension cords burn out in our kitchen, what thank got the circuit breaker got and shut, so just the extension cord got burnt nothing else. But would never trust a simple cord. You can't rely on people start counting Amps when they connect a machine on a cord. But i never noticed Fuses in the cord. Maybe they are there i just never looked at it?

    Back in the 1970's I put some Cibie pencil beam headlights in my "turn signal" housings on my Opel GT. I needed wiring and was a hi-fi guy so I used some brown speaker wire to wire them to a relay powered by my high beam circuit and took it on the road one night. I was having fun on back roads (those lights are like airplane landing lights) and suddenly my lights got dim. I got out and discovered all my regular lights were on, but these were not. I checked the wiring and discovered the insulation had melted, allowing the wire to touch the metal of the car body in the engine compartment, blowing the fuse (at least I fused them). Learn something every day. :)

    I just had a 30x60 garage/shop built on my property but it took almost a year to get an electrician to do the initial wiring. In the meantime, It is 100' from my house, so I used a 100 foot 12 g extension cord to get power to it and was careful to only use one power tool at a time. I knew I was going to lose some power, but whatayagonnado? Anyway, I had a large harbor freight air compressor and the darned thing always had a hard time starting up. I thought maybe I had put too much oil in and increased compression too much (I actually did that with a cylinder "cleaner" with a car once a couple of decades ago). Anyway, every time it needed to turn on I had to babysit the valve on top to allow it to get up to speed. I thought maybe the valve was defective. Then the building got wired and I plugged it in. It was like I quadrupled the horsepower (at least regarding start-up power). It fired up every time without a hitch. It was just not getting enough power from that extension cord.

    The 520R is not necessarily commercial. It may be installed for devices such as evaporating coolers and A/C. I have two in my home for "swamp coolers". There's also one outside for our irrigation pump. Whether they are necessary or not is another debate entirely. Also, I have one in my pop-up camper for the A/C.

    Your system is crazy. Faulty appliances frequently blow fuses keeping people safe from electrocution as well as fire. We have a fuse for every appliance on the extension cord and one on the cord. E.g. My TV needs only a 3 amp fuse!! Our plug socket breakers are rated at 32 amps but the cable is rated at 40 amps because the ring main has two 20 amp cables going back to the breaker. RCD breakers are present in addition to the standard breaker that trip within 30ms of you touching a live cable - in fact a fuse blowing or a faulty bulb will often trip it.

    I lost everything in an electrical fire back in 2015. I was renting a beautiful apartment-a “modern” addition to an old farmhouse where my landlord lived. The problem? Uggghh..there were many, but the biggest one is in my very tiny rural town, my landlord, whose family has lived here for 100+ years, had the money and connections to bypass safety inspections when he built the apartment. Of course, I was just shown the paperwork showing everything was up to code and that it had been installed by a certified contractor. It wasn’t and he wasn’t certified. I knew enough about electricity (years ago I had assisted a REAL electrician install power to a home I was building.) to know that the constant power surges & blown fuses= wrong wires. I even had a minor fire just 4 months before the big one and I was in the process of finding another place to move to. I’d lost about $2000 in electronics and was repeatedly told I didn’t know what I was taking about and was “making a mountain out of a molehill”. DURING the fire, the landlord was already trying to bribe me into keeping my mouth shut; after the fire, it escalated because they were also committing fraud having 2 identical policies on my apartment, with 2 different companies. It was a mess, to put it mildly. They even tried blaming ME, just a tenant who stayed to herself most of the time..with my precious feline, Sita, who perished in the fire. 🤬 Luckily, one of their insurance companies had a good, not-payed-off investigator, who figured out they had the wrong wiring-AT EVERY POINT-pole to box, box to house, even the wiring in the walls was basically cheap extension wiring. It was SO bad that at least 4 people lost their jobs and my landlords, who’d purchased a few new cars already with the first payout from the other company, (they’d even claimed they lost their vehicles in the fire-along with their home, “office” (MY apartment), “greenhouse” (the almost empty except for junk, garage, under 1/2 my apartment), and “gym and physical therapy space”, (my landlord also claimed to be disabled and they had an old jacuzzi in a shed in between my apartment & the farmhouse. When I first moved in they claimed to be working on it because I am actually disabled…and part of my rent was for the use of this room that was never finished or of any use..kind of like the AC I also paid extra for that didn’t work because of the wiring) Bottom line, after trying to blame MY 1 extension cord that wasn’t even plugged in when the fire started, in a wall not even connected with my apartment (I’ll never forget her saying ”they‘ll never know where it started unless you tell them!”. She’s NOT the brightest bulb in the box…😂), they got off with restitution and fines, for the most part. I was urged by my attorney to sue them, but considering I wasn’t able to move out of town because of my health at the time, (I had a heart attack exactly a month after the fire); I settled on a VERY small settlement and an order of protection. Wire gauges…the stuff of soap operas in small town USA.

    So in the 'states extension safety is because all the resulting fires have scared people? And what's up with using the hob to boil a kettle? On 240v mains we just plug it into a socket - any socket - and have a kettle of boiling water in 2-3 minutes.

    Another fascinating video... thank you! 😀 I recently bought a second-hand US snow cone maker in the UK. The previous owner had simply snipped off the US plug and stuck on a UK one... and plugged it in! They were selling it as it was “way too noisy whilst in use”... duh cranking 230v through a 120v is a very bad idea all round! So I removed the British plug and looked to buy a US plug so I could use it with my UK to US voltage converters... how hard was it to find one!!! It appears that in the US if a plug is damaged you’re expected to replace the whole cord with a plug already moulded onto it... or throw the whole item away. I did eventually find one (like a needle in a haystack) and the snow cone maker works absolutely fine (the kids love it) as it was only run on 230v for a very short time. P.S. To be 100% sure I did open it up and check the brushes, commutators and wiring etc, all were intact... phew!
