How to make twist the wires ?

What is the danger of such a connection?

Curl - this is the most dangerous way to connect wires, becausein this case, two or more contact conductors will depend on the quality of the work done.If you are slightly bent wires through them time to relax, and in the place of bonding to the weak contact.This problem area at high current loads will be continuously heated, the insulation begins to melt and the resulting short circuit can occur, not to mention the fire alarm and the person an electric shock.

No wonder the SAE rules is strictly prohibited to use this method in electrical work.Despite this, most of the electricians, and even experienced, uses this method in everyday repair work.

should be noted that if properly twist wires together, carefully insulate the stripped area, no problem.Moreover, twisted veins can last for decades, if we consider that it is the method used in most of the old houses and apartments.

So, how correctly to make twist the wires?This is what we are now and we'll talk!

Detailed instructions

First, consider the simplest option when it is necessary to fasten two single-core conductors of the same metal (eg copper).

technology as follows:

1. we clean thoroughly both strands of insulation approximately 4-5 cm To do this, you can also use a special tool for removal of isolation..
2. Wipe the exposed contacts with a cloth soaked in acetone (degreasing).
3. sandpaper we clean up the ends of the metallic color.
4. crosses wires together and one of the threads carefully screwed onto the other with a pair of pliers.Number of turns to do at least five.
5. second cheat a similar method for 5-7 turns.
6. us isolate the finished twist with electrical tape.It is also recommended to use heat shrinkable tubing - tubing that protects the bare area of ​​the environment.

As you can see, nothing complicated.The peculiarity lies in the fact that it is necessary to bare conductors not less than 5 cm and twist the pliers that was unbroken and reliable contact.

I would also like to give a couple of tips about the more complex situation when you need to make a twisting of solid and stranded wires.In this case, first repeat step "1" and "2" of the instructions provided above.Next, cross product, and stranded wire closely wound in the middle of a single-core (at a distance of 2.5 cm from the end).When all the windings are wound will be the free end of the conductor must be stranded pliers to bend in the direction of turns, as shown in the photo below.Thereafter, the compound is isolated and fit into the junction box.By the way, in the same way you can make a good twist of two stranded wires.

should draw your attention to the fact that to do twisting of aluminum and copper is not recommended by experienced electricians, not to mention the GOST standards.This is due to a variety of metal resistance, as well as the fact that the interaction of oxidized copper and aluminum, which significantly degrades the electrical contact.Another disadvantage is that the twisting of different metals (in physical properties) will occur: hard and soft, which also deteriorates the contact.

Useful tips from

professionals to make twist the wires reliable, durable and safe, most importantly, we recommend you to consider the following recommendations:

1. Additionally twisted contacts canconnect the subsequent welding or soldering, making contact as safe and unbreakable.Incidentally soldering is best used when both cores of a large cross-section.
2. Modern WAGO terminals can be used much more efficiently, besides the accession process will be faster.It should also be noted that vagami can be connected not only aluminum and copper, but several wires simultaneously, and they may even be different cross section, which does not affect the reliability of the contact.If you decide to connect the wires in a wall outlet or a chandelier, it is best to do this with the help of the WAGO terminal blocks.
   
3. PPE clamps increase reliability of connections, making it more secure.Products are cheap and have a low cost, so we recommend to use a wire twist caps PPE.
4. After you make a connection wire strand, do not rush to hide a new site in the terminal boxes.Within a few hours, let the electric circuit will work, then check the temperature on the site of bonding.If the compound is heated, it is best to do it all, becausethis indicates an unreliable contact.

important to note that none of the above options do not twist waterproof, so if you decide to seal the wires under the plaster on the wall, without a box, be sure to insulate the connector cambric.

That's all you need to know about how to make twist the wires by hand.We strongly recommend you to use more modern methods, and twisting to apply only when installing temporary electrical wiring!In no case do not twist under stress becauseToday there is not so safe way.Any electrical work should always be done with the light off!
