Как моряк, скажу, что узелки надежные. А как электрик, скажу строго: так ни в коем случае нельзя делать. При соединении провода важна площадь соприкосновения, а не крепость узелка.

Being a Master Electrician and 44 years of Doing electrical installation…. NEVER NEVER NEVER do this. We rip the wire out and replace it. Splices are made with approved connectors rated for heat. Heat causes fires 🔥

I one hundred percent agree with Dave Pitso. I also am a master electrician and in my 40 years of experience, would never make in-line splices in wire. All splices would be made in accessible boxes, with code recognized splicing methods.

I agree with This Guy. They definitely break code. I’m an industrial maintenance technician. And everywhere I’ve worked would fire you in a heartbeat for making connections like this!

"Электрики не хотят, чтобы вы это знали!" Абсолютно верно. Такой херни не хотим, чтобы вы знали.

Being an electrician myself I would never use these methods. For one they break code. There is bending radiuses for wire and these knots exceed those radiuses. Only exception would be curling the wire to install it under a terminal such as a receptacle. Only approved methods can be used by electricians or we become liable. Two, the knots void the UL listing, so if an electrical fire is caused by this and the insurance company discovers this method you can say good bye for insurance covering any damages.

This is the best I have ever come across for those MacGyver fixes. I never thought I would see the Rosendahl knot/Zeppelin Bend used here.

Well the comments were in the end far more educational the video. I never knew becus I'm not an electrician. But sure glad I read the constructive comments , which is an SOP for me when watching something I really am a novive at. Though wire nuts have been my preferred method for what I have done. Thank you folks for the help.

Здравствуйте Уважаемые , хотелось бы посмотреть , что бы сделали Настоящие электрики , с Тем , кто навяжет подобные узлы , скажем в разводочной коробке на каком предприятии ??? Этого мастера , самого завяжут подобным узлом . Мир вашему дому .👏👏👏👍.

Retired firefighter here. This is the type stuff that granted me a 30 year career .

Va mulțumesc frumos pentru asemenea documentar

I usually use an insulated crimp connector for the ends of the two wires. Crimping is important because it (a) ensures that both wires are good and tight, and (2) increases the area of contact so as to reduce heat generated. Twisting wires are not a good idea if the current is high, especially in household power devices.

There's a reason electricians don't want you to do these. I expect firemen don't want you doing it either.

I’m a qualified electrician and have been for 24 years and I have not and would not join electrical cables together like this, I would also recommend anyone watching this not to use this method either, you can buy connectors of various different types that are much better much easier and far more electrically sound than any of the methods shown.

I have never seen anything as numbing as these methods. Wow! Absolutely amazed at the Primitive Pete recommendations.

Usted es de seguro un profesional muy viejo tremendo maestro los de mi época gracias por su enseñanza.

I’ve been a master electrician for 27 years. And can say, I don’t know why I wouldn’t want you to know this? Just don’t expect it to be cheap to fix it when you call one of us because you burned your house down by doing it incorrectly.

As a Union Wireman I tell you , I WOULD NEVER tie wires like this.

عمل ممتاز .. بارك الله فيك ونفع بك

Brilliant really. Thanks.

Electricians very, very rarely solder wires. There are many safe, sound and UL approved systems designed to do everything you covered here. Soldering is generally used where space is very restricted and the heat used wouldn't cause other problems such as melting insulation. This is usually the case in electronic equipment. One more thing: The stresses you are creating with these knots can actually _weaken_ the conductors. Leave electricity to the trained and qualified.

Да! Ты абсолютно прав! Электрики, как нормальные вменяемые люди, не хотят что бы кто то повторял за тобой вот эту хрень! Я тебе скажу больше. Пожарники тоже не хотят, что бы ты давал такие советы тем, кто до этого не знал правила и нормы электромонтажа! И медики этого не хотят! Себе пальцы порезал и другим советуешь?! Макраме не имеет ни чего общего с электричеством! Там другие законы работают! Удали на хрен это видео! Не бери грех на душу!

Verygood

Wow! Ty. Very 😎

These connections would probably be OK for some low-voltage applications (hobby electronics, etc), but *THIS IS VERY DANGEROUS FOR HOUSEHOLD AC WIRES.* The reason "electricians don't want you to know this" is because *it could actually burn your house down* if you do it. The shown connections do not comply with electrical codes the US, or likely in most other countries, and for good reason. There is no way to guarantee that they are making enough contact to carry the sorts of current that is often required, and if the connection is not good enough they can get hot enough to actually cause fires, or possibly even produce arcing, etc. Even if the connection starts out OK, it can also wiggle looser over time (the shrink tubing alone is not enough to guarantee it will stay tight), causing dangerous conditions to develop later. There are actually already many much better (and approved) methods for connecting wires without soldering them, such as wire nuts, Wago connectors, crimp-on connectors, etc. Please use those instead. This is just not the right way to do this.

Not being an eletrician, i can only say: never connect or mix blue wires with brown ones, unless you really really know what you are doing.😀

All you electricians are right, we get it, it’s not code! But when it’s end times and all I have is wire and electrical tape, damn skippy I’ll be using this. Great video Maker!

Nice trick!

Это что, всевозможные морские узлы только не из верёвок а из проводов? Для чего это? Как это можно использовать в реальном монтаже под потолком?

As an Electrical Engineer and past Electrician, I'll say every one of these splices is bad, even for low voltage. Wire splices can be made more easily and better than any of these and the right methods are easily found online.

First time I've seen a zeppelin bend for joining wires... brilliant

somente a última dica achei útil. Mas já valeu o vídeo.

When a sailor wants to be an electrician ... 😉

Hi, I had 31 years of experience in electrical engineering. Electrical connections in most cases do not require soldering. The wire amp should be higher than the consumer amp. The solder fills the gaps between the wires and the wire is connected properly. In a soldered joint, the wire may heat up, but the wire will not heat up from the soldered joint and electricity will pass completely. In addition, the solder is a waterproof insulation and prevents blackening and sulfation of the wire.

Esos amarres están buenos, aunque la mayoría no son funcionales para instalaciones eléctricas y los menos se complicaría bastante el utilizarlos.

very nice

Deberías saber que los empalmes por retorcimiento ESTÁN PROHIBIDOS según normativa en Europa y ESPAÑA

Так то,да! Это узлы Альпинистов!!! И если матать как показано на видео! То! ФИАСКО БРАТАН!)))

Умиляют эти интригующие заголовки...😀

Может разве что для соединения тоненьких проводов в мелкоаольтовой и мелкоамперной технике. Поовода такого сечения расчитаны под высокое нарряжение и силу тока. В силу того, что провода окисляются и оксидная пленка обладает высоким сопротивлением, места такой скрутки со временем окислятся, начнут греться и могут вызвать пожар. А потому только пайка

А можно вопрос - а почему в снипах разрешены только сварка, пайка и пружинные клемники? Не потому ли, что при подобных соединениях пятно контакта порой крайне мало, происходит цикличный нагрев соединения, его расширение и ослабевание. А в последствии, в ряде случаев, перегрев, искрение и пожар?

На столе красиво и ровненькие,а на стене или на потолке когда длина 3-4см. Пускай также продемонстрирует.

BOMBASTIC !

Rất đẹp và chắc chắn

Спасибо, улыбнуло ))

I’m an electrician 45 years never made a splice like that and would never think of doing that. Basically a knot in the wire. People not a secret (all electricians and inspectors will tell you to only use UL listed wire connectors when making a splice). Faster and better.

Merci.

As yes. When I tap into knob and tube so I can power my new Edison bulb. I always use this method.

Splicing wires isn't a conspiracy, and that is some of the worst slicing I'm ever seen. Ropes and electrical wires are different beasts. An electrical splice is more about keeping the electrical resistance low rather than the physical strength. Sure, wires will conduct just by touching, but there's more you need to do to make it safe. A poor connection will heat up potentially causing a fire, so a solid connection is important. Soldering slices or just using proper connectors is highly recommended especially with high loads. It's good practice with all loads.

I don't think many of the electrician do like this.

Kontár munka és életveszélyes!

Ну это видео больше подходит в тематику про морские узлы =)) И есть подозрение, что с такими крупными скрутками это будет греться.

For those that forget to slip shrink tubing on, slide some on the wire before you make the connection. I still forget occasionally and know better.

Видио от рыболова а не от электрика. Клеммы и пайку отменили? Для чего узлы? Провод не несёт никакой силовой нагрузки.

Как электрик скажу, что для соединения важна площадь соприкосновения и чтобы ничего нигде не выперало и тем самым не испортило изоляцию. А здесь показатели морские узлы. Причем в электрических сетях такие вещи применять только хуже делать.

A good idea

Hi as a home repair man who went to school for electical work. This breaks all codes. And the knot will act as a resister in the line and choke the flow of current. And will cause a fire due to the knot heating up. So please dont use this.

This is fine for low voltage devices except for the fact that it should always be soldered. The knots themselves help to anchor but the connection needs to be soldered/sweated together. I agree wholeheartedly with everyone else about any wiring running household current/voltage. Beats some of the crappy crimp connections for car stereo, etc.

Show de bola

Good

Trabalho como Técnico em Elétrica a quase 4 décadas e isto aí é um crime. 😂😂😂

Диванный теоретик😁

heartstopping.

This is very good but I would certainly solder these connections.

HILARIOUS!....I can't wait for this guy's next video: "What mechanics don't want you to know....easy and cheap brake jobs for DIYers".....LOL

these knots are good with string. for better electrical contacts either solder or a good crimp

Connect the hot and cold leads (+/-) together in a knot… Brilliant! should we shut down power before or after? …please do tell

Eu como eletricista amador que sou não usaria nenhuma dessas gambiarras aí, não recomendo. Mas cada um é responsável pelo seu próprio resultado!

nám elektrikárom je jedno, či to viete. a spojiť modrý vodič s hnedým je excelentný nápad. len tak ďalej.

Сразу видно не электрик, а рыбак, ещё-бы воблер прицепил, вообще бы красота была.

Realmente não vou querer que as pessoas saibam disso, pois tá muito errado. Isso vai dar um ponto quente que vc nem imagina meu companheiro.

Super Glue....... :)

Nice video information for details 👍

How about just using a wirenut, a mechanical connection and can be taken apart if needed.

Muy buena idea . maestro gracias por compartir su conocimiento.

Это гениально!!!

The problem with this method, is hysteresis or heating up the connection.

while this works sorta it is not a proper connection for mains electricity, you can get away with it on lower voltages but the unsoldered contacts will corrode be really inefficient the added resistance could cause a fire or just quit working.

Being an Electronic Engineer let me explain why this is a bad idea and what soldering (and crimping) is for. Solder decreases the resistivity that is introduced by joining two pieces of wire together. So why does it matter about increased resistivity? Aside from meaning that increased resistivity will cost you money from the lost energy far in excess of the money saved by not using solder, it introduces a hidden weakness in the wiring that the knots won't overcome which over time will get progressively worse. That area will act as a fuse as sparking and burning reduces the thickness of the actual connecting points of the joint to a point that's less than the rating of the fuse in the fuse box which would usually protect your wiring. So even if it doesn't spark a fire which with the increased resistivity at that point equals increased heating which equals even more increased resistivity, over time there will be charring in the area further reducing the total connectivity at the point which in turn increases the resistivity, which means even more heat and so on. Soldering the connection introduces a far larger surface area of connection, thus avoiding this potential problem. Crimping is similar in that the copper strand(s) are crushed creating a far larger surface of contact thus reducing the resistivity introduced due to a join. It's not a pointless standard but there for a reason.

This is safe enough. I’m not an electrician but I did stay at a holiday in last night.

Wenn ich das auf der arbeit machen würde, würde ich eine reine gehauen bekommen

I've been an electrician for 45 years and I don't mind if you see the video. Most of the time we use wire nuts or butt splicer terminals. I'm wondering what the plumbers don't want us to know.

Согласен. Способы добротные. Жаль не везде в ГП(наверно, нигде), термоусадок не дают😂

Ukryte zwarcie, gratuluję!

As a farmer for many years always rushed for time looking for shortcuts that work...first glance I thought well that looks great...after reading comments from electrician...I will NEVER DO THIS

Lendo alguns comentários de eletricistas de outros países, vemos que de acordo com as recomendações e boas práticas, esses métodos podem causar danos as instalações. Como disse um comentarista, "Nunca Nunca Nuca faça isso!".

I am not electrician, just electricians son. But if I ever treated wires in this manner, my dad would take them and whip the hell out of me with them. To this day I get nervous when I see normal people rolling up their extension cords, brings back memories...

Насколько я помню, любые скрутки по ПУЭ просто недопустимы.

В каких нормативных документах описаны эти способы соединений проводов?

Long live impedances to the fullest! If you want to learn how to tie knots, visit the mariner section, this is electricity, and here the best thing to do is to use the soldering iron...

Lovely tip, thanks.

Das goed als noodoplossing om heel even verder te kunnen. Op lange termijn heb je kans op vonkvorming als de kabel/draad beweegt wat weer brandgevaar met zich meebrengt.

Apart from all the shortcomings pointed out in the previous comments, what actual application would require one to splice two conductors at the midpoint?

21st century. The best contact and transmission of electricity was shown by means of copper feet, soldering and only manual winding.

Por cortar en esa dirección se iba quedando sin uñita,ten cuidado.La seguridad industrial ante todo!!!!

Electricity is magnetism and those curls in the wire create eddy's in the magnetism, over heat and fire 🔥 🚒 easy

The fact that this "instructional video" uses the euro live (line) and neutral colours and they are joining these two kinds says it all. That's just my 27+ years in fire investigation talking. Resistive heating/poor terminations are by far the more serious risk of fire in domestic and most commercial wiring.

Lo harías en una instalación? En un trabajo grande? O en un trabajo chico? Te gastarías el tiempo en unir cables de esa manera, uniendo cables por la mitad sin ningún sentido o cual seria el sentido de la unión?

These are common knots being done on electrical wire. And while they will work, they most likely will NOT pass any code inspection. These knots, however, work great with thin line--like fishing line--and small diameter rope.

Knots good for fishing (exlusively)!
