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.

You didn't cover the matter of short circuits. This is relevant to the discussion about extension cords and voltage (120/240). In case you'll make more videoes about these things, you may find this interesting: Extension cords: There are two ways to trip most circuit breakers, overload (current only slightly higher than the nominal current) and short circuit (A very high current). Circuit breakers and wires in your house are chosen so that the circuit breakers will be tripped instantly by the smallest short circuit current that can occur in your house. Any extension of wiring reduces the minimum short circuit that can occur because of increased resistance. This may cause the circuit breaker to not instantly trip during a short circuit. This is why long extension cords can be bad. The circuit may eventually trip because of overload, but this may take to long with the still quite high currents of the short circuit. I'm not sure how it is in the US, but in Europe the short current tripping threshold for circuit breakers is commonly 5 or 10 times the nominal current. That means that you may need to have a short circuit current of 10x20A = 200A to trip a 20A circuit breaker instantly. If the short circuit current goes below the instant tripping threshold of the circuit breaker, the circuit breaker may not even be able to protect the wiring in the walls. 120/240 Volts Minimum short circuit current is more rapidly reduced by extended wiring if the voltage is low. Unfortunately calculations of minimum short circuit current is complicated and depends on the electrical supply to the house. Every component from the generator in the power plant to the end of the extension cord needs to be taken into account. This is why the electrical companies need to supply information about short circuit currents values at the point where the house is connected to the grid. This makes it hard to give you an example, but I'll try to give a rough one: Circuit breaker size: 15A Circuit breaker instant trip threshold: 10x15A = 150A Minimum short circuit current at socket outlet: 400A (This number varies greatly depending on the grid and house wiring) Maximum length of 1,5mm2 (16awg) cable that results in a short circuit current of 150A at 120V: about 38 meters (125 feet) Maximum length of 1,5mm2 (16awg) cable that results in a short circuit current of 150A at 240V: about 76 meters (250 feet) This severely simplified example shows that you can use extension cords that are twice as long with 240V compared to 140V. This example is not apples to apples however, because the resistance of the grid is not the same for the two calculations. The 240V grid must have a higher resistance to give the same minimum short circuit current at the socket outlet.

OSHA requires all job sites to use GFCI (ground fault circuit interrupter) on all extension cords used, either built in or an add on between cord/tool and outlet being used for safety and all cords must be of a certain diameter/gauge to be adequate for amps drawn. Those multi plug (3 way) extension cords are for the TV/VCR/Stereo combos of the 70s/80s in homes built in 1920s-1960s when outlets were less and mostly 2 prong. Consumers and private businesses should really follow more OSHA guidelines cuz their life's would be less stressed and far safer in application of common sense once that basic information is shared with others.

In the US, most devices that draw more than about 10 amps come with a user manual that tells you what length and wire gauge extensions cords are safe to use with the device. They will say something if you use a 10 foot extension cord it must be at least 16 gauge, if the cord is 14 gauage you can go up to 25 feet. For 50 feet use a 12 gauge extension cord. Do not use an extension cord longer than 50 feet. Yes stupid people stupidly do not read the owners manual and stupidly use an unsafe extension cord. I frequenlty see this when I go into people's houses. I think that social Social Services should take their children away but, they don't, and worse, I've gone into the houses of social workers who work for child protective services - and THEY use extension cords unsafely.

I'm happy to live in Austria, where all power sockets and extension cables are made for 16A/230V. In the wall can be wires with 1,5mm² / 12A (mostly for lights) and 2,5mm² / 16A. Extension cables on drums have a breaker since around 20 years. There can be some thiner extension cables with special small Europlugs on both sides with only 2 connectors without grounding. But such connectors are only on double insulated devices with a maximum of 2,5A/230V. For 20A/230V, you have to use a blue CEE connector. It is rarely used. You have such a mess in your safety standards in the US. 🤪

@10:00 If you have a wire coiled like that and are drawing a lot of power, it will heat up because you just created a crude INDUCTOR... Basically you just made a simple electrical component that makes magnetic fields push back on the current flow in your wire, creating resistance (aka heat). Whatever people do, PLEASE remember to try and NOT run cables coiled up!!! Spaghetti rats next? Totally okay! A neat coil? Dangerous in the worst scenario, and simply wasteful in the best scenario (as ultimately you'll have to draw more power from the wall to get past the resistance). Just say no to coils!

Once you get heart fibrillation the voltage doesn't really matter. Given that your video is about extension cord wire gauge, I'd expect you to argue the opposite - that 240V is safer because you only need to pass 1/2 the amperage to get the same amount of power.

About the « safer » voltage (my quotes, for typography savvy, say that ‘m French, a 220-250 V 50 Hz, 75% nuclear, 30 mA differential breaker protected citizen ), I was told your 120 V just tingles and you might stay on it and cook longer whereas 240 V has a spicier feel and whether you are dum or not your limbs will get out of there fast. However your issue still applies here. We don’t have fuses in plugs or sockets like the brits do. Good job. Do you realise your voice resembles that of captain desilusion ?

Another problem is technology. Nobody anticipated the explosion of electrical usage outside the kitchen. Air conditioning seriously increased loads. Next came computers. Finally, people simply don't understand electrical loads. In the old days you had to choose what you ran. If you tried to run too many things it would trip a breaker. "No. You can't make coffee and toast at the same time. Make the coffee first. Then you can run the toaster." Yup... that was a ways back. Check out "Ma and Pa Kettle Go to Town" for an idea of what they thought the future looked like. You will enjoy it.

Fusing within the plug is a sound idea. In the UK there are different sized cartridge fuses to suit the expected load. If there's a problem, it's people using the greatest rating, 13A, for even the smallest of loads. Anyone with a computer set-up will soon run out of outlets. A fused power strip with multiple outlets mounted on the wall is a way to cope.

It is insanely stupid design to require a normal user to understand load limits. There is this logical fallacy in design. "It is fine, as long as nobody makes a mistake." The falacy is that it being fine most of the time proliferates it until mistakes become a certainty. In OS design, Cooperative Multitasking is fine provided nobody makes a mistake. In C++, Handling naked pointers is fine provided nobody makes a mistake. Both made programming so accessible, a *lot* of people ended up making mistakes.

In India, we have a device which is a combination of rccb and eccb (I don't know the exact name. Similar to this www.amazon.in/ELCB-DPG-40-Single-Phase/dp/B071HGCM33) which is used as the main switch of our houses. This can detect any deviations in current within line and neutral and cut the power supply immediately. This also prevents shock as it's just 5 milli sec response time. And it protects the whole house circuit. (MCB will be added after this in the circuit). Almost all newer houses has devices like this. And if you don't know already, we always have switches for each outlet and we turn them off when the outlet is not in use. Smart right🙂

They're all actually 8ga or 10ga and lie and say it's 6 but in the fine print they say what it is. Had to search deep and pay top dollar for an Eastwood cord that's about 1" diameter and true 6ga. Funny thing is the welders cord itself is thin af. Felt silly buying heavy wiring but that's the right way to do it.

The fun we had, installing the 3x63A (400V) outlet and dragging along the 25m cable for the crane when extending our house. That thing would draw some 30kW. 😄 Pretty happy, that almost all extensions here (Germany) can handle 3000W, at least for a while. 12 gauge, 16 gauge? We put 3x1.5mm^2 or 5x2.5mm^2 inside our walls and usually have 16A circuit breakers on everything. The cables are all grey, but the diameter is written on the outside. And since 2007, RCCB (ground fault) is mandatory for pretty much every outlet indoors.

Not sure if that’s an issue here in EU. Never noticed anything like them getting warm at all. However, I do know the morons didn’t wire the stuff here that well, or just didn’t expect me to use so much power on that side of the wall. If I use the outlet 3 meters away from another outlet and have a water boiler in one and microwave in the other, the breaker trips. Can’t run them at the same time, which can be annoying sometimes. But I can run pretty much anything else there at the same time, just not those two. But I guess both the boiler and microwave are examples of extremely power hungry devices.

In power strips they often use a system where the socket is just crimped to the wire on the inside. This ends up being a weak point in the circuit. After experiencing several sockets overheating at my business we opened up every power strip and soldered the socket to the wire inside. Never had a socket overheat after that.

In the EU you never see a fuse on a plug / extension cord either. At least I never saw one in 20 years of going to friends and family places in Europe. Someone told me they do put fuses inside most appliances but then you usually have to take them apart to replace it, not sure how true that is.

The house across the street from me literally burned to the ground because a resident ran a long extension cord from a screen porch to power some appliance in his room inside. The heat from the cord ignited something flammable on the porch or the porch itself and the house was destroyed, engulfed in flames. Fortunately everyone got out safely, but they lost everything. it was a good object lesson.

So do Americans still use those ancient Square D or Quicklag style breakers?They went out with the Ark.In Australia we use Hager similar style of mini circuit breaker with typically 6KA fault level.Our wiring is measured by cross sectional area.7 strands of .075 sq mm cable which equates to 2,5 sq mm rated at 20 A at 240 v (power circuits)and 7 stands of .05 sq mm which equates to 1.5 sq mm rated at 10 a (for lighting) All new premises have to have RCD/MCB breakers and are required for any alterations to existing wiring.We don't use wall in houses instead using stud brackets nailed to the stud.The plasterer pokes the wire though the hole and you just install the power point or switch.Far easier and quicker.We use TPS(thermo plastic sheathed) cable (double insulated) normally on a 100 metre roll and rough in houses that way.Very rarely use conduit except in metal sheds or industrial situations.

Wire gauge is less confusing if you know that it was originally the number of wire drawing dies needed to reduce the raw material (0 gauge wire) to a particular size. 16 gauge goes through two more drawing dies than 14 gauge, therefore it is smaller.

There's no reason to make tripwires safer that would only cause more people to trip over these wires. It's the first thing home health should have removed from the home. There's no reason to educate people on how to make tripwires more safe from fire. It's always better to ask if the solution worse than the problem. Making our electric less safe is not a good way to encourage people to buy extension cords with fuses. Extension cords ruin lives.

You might want a second video on cords talking about size and length, and resistive vs inductive loads. Plenty of electric motors have there life shortened by voltage drop on start with longer/lighter cords.

We think the same way when it comes to the word "safer." To me, all comparative adjectives are relative to the other thing being compared. So when I say Lamborghini is cheaper than a Bugatti doesn't mean an Aventador is cheap, it just means it's not as expensive as a Chiron.

I work in a supply warehouse for all of this kind of stuff. So feel free to ask me anything, But that being said, I am just in the warehouse, I am not an expert on any of this stuff. On the front of every receptacle, it tells you if it is a 15 or 20 amp receptacle, But it is always covered by the face plate put over it. The sideways notch is not in every 20 amp receptacle. Most receptacles that we sell are just standard 15 or 20 amp, Then the Tamper Resistant are the next most common. Followed by waterproof tamper resistant, And eventually some long acryonm that I don't know the meaning off. Something like GFWTI (there are a few different types) You can get circuit breakers that go up to 100 amp, but those are not sold often. In residential, The biggest wire used would be 4/0, But that is not the biggest sized wire. Personally, The biggest run i have seen is 4 separate wires of 900, 900 is about an inch thick, maybe a bit more. Personally not sure what it's used for, I think it was running power into an apartment complex. Normally, in residential, you will not go smaller then 16 or 18 gauge wire, And the biggest will normally be SEU 4/0 4/0 2/0 ( 2 separate 4/0 cable and a 2/0 cable). Above 4/0 it goes to 250, 300, 350, 500,750. There are other sizes, like the 900 i mentioned, But they are not common. the color coded wire is not all made the same. It can either be 10/2 or 10/3, And the other color (Yellow if i remember correctly) Is either 12/2 or 12/3, depending on how many wires are in the jacket. Normally the */3 is for running 240 volt appliances. one hot for 120v, one hot for 240, And a neutral (And a ground that is not part of the number system) There is Also SO and SJ 12/3, Which has the same amount of wires as a romex 12/2 cable. Normally an SO 12/3 would be run for like.. running a foot pedal to some machinery to turn on the machinery. As i said, If anyone has any questions, feel free to ask, But there is no guarantee i know the answer. It's all just stuff i have picked up while working there.

I don't see those cords getting anywhere near 450°F so how are they going to set anything on fire unless there near something with an unusually low flashpoint. Also increased temperature would increase the resistance which would in turn increase the current draw potentially causing the circuit to blow anyway.

Folks, spend the extra ten bucks on an extension cord and get the heavy 10ga construction-grade extension cord.

My childhood home burned to the ground when I was like 6. The fire marshal determined an extension cable (a 20A rated cable) caught fire when a freezer started drawing a fuckload of current and the glass fuse (old home) did not pop.

Fuses in chords fix nothing. Consumers will either throw away "broken" chord or put the wrong fuse (in a good day) or puta thick wire to replace the fuse (most of the time). Thanks god we stopped using wire fuses (for house protection, not devices) and replaced them with automatic. All the wire fuses left in the houses are most likely replaced with thick wires. At least all that I've seen. People freak out "I don't know how to change a fuse, what fuse to buy?" Then the smart neighbour comes and fixes the problem with a thick wire and everyone is happy.

All these problems come from using the "safe" 110V. Here all the extension cords are 16 amps (because that's how much you need for most devices on 220V), excluding chinese stuff that can be anywhere between 1A and 10A. Because of chinese products flood you still have to watch out for bad extension cords, but you can easily avoid that by going to a good shop and buying a reputable brand.

I use surge protectors and actually make sure everything is properly gauged. It's one of those situations where it's not an issue if you're not a dumbass... therein lies the problem; most people are dumbasses. Silly warnings like slippery when wet, or warning that hot coffee is hot. Gotta put out a sign or cones when mopping, because some fool will sue you for their failure to be observant.

Many thanks for this great video. It explains a lot in a good maner that even I as a not native speaker could understand it. I knew that the electrical system in the US is dangerous. However I didn't know it is soo dangerous. Growing up in good old europe I am used to a different system. Starting with the plugs where it is impossible to unplug it half and see the connectors which are still hot. Imagine you touch them or drop some metal, e.g. a spoon and it accidently connects both... Well, you get the idea. I will not say everything is good over here. Definitely it is not. The idea in the UK having fuses in the plug is great. I like it. The plug itself is not in my opinion. Better are the german plugs where everything is covered when you plug them in. Sadly they don't have fuses. Even better are the french ones because you can plug them in in one way only.You always know which wires are the hot ones. My two cents to 110V being saver than 220V: If you touch it, yes, it can be saver. On the other hand with 220V you halfen the current in the wires with the same power at the output. The cabeling stays cooler that way.

Where I live, we've attemped to mitigate this by having 10A and 20A nominal current outlets / plugs. A 20A plug won't fit inside a 10A outlet but a 10A plug will fit inside a 20A outlet. Still doesn't do much for us since extension cords with 8 or more outlets are still a thing.
