What are the ways to connect the wires in the junction box there

So you've decided to completely redo your old likely has an aluminum two-core wiring for modern three-core copper. We have already prepared the schema and even marked out the route, which will be laid cable. But you think, what way they will connect you to the junction box. If not yet, or are in doubt, then this article will help you. After all, here I will tell you about all the existing methods of connection, as well as sanctify all the strengths and weaknesses of a particular type.

Classical twist

Despite the rapid development of technology, still a lot of artists use the most ordinary twist. After all, for its implementation does not need absolutely no additional movements. Just we clean the cable cores, and isolate them curl back. As they say, cheap and cheerful.

Pros: in this way, I can only highlight a couple of advantages - it is fast and free of charge.

Cons: in the usual twisting, as if she had not been performed qualitatively, with the passage of time weakens contact, which means that when a large load is the place to be heated, but it does not good. In addition, this method is prohibited by the rules of the SAE.

You also can not connect aluminum and copper.

Twisting with welds

This method is a more advanced version of the conventional twisting and for the realization of you still need a soldering iron, rosin and solder. We still do twist, and then, twisted wires, propaivaem using a soldering iron.

This method eliminates the conventional negative twisting and provides a secure connection of the wires for a very long time.

Cons: inconvenience of the installation as a box often make the ceiling (bottom arrangement is practically not used), the installation process is quite time-consuming.

Again, it is impossible to connect copper and aluminum wires.

Welding

This method is increasingly gaining popularity among professionals engaged in wiring. The essence of this method is that, using a conventional inverter welding welded to the ends of the pre-twisted wires.

Pros: This is a very reliable way to connect to the terminal boxes.

Cons: For relative disadvantages include the time that you need to own welding machine and a basic knowledge of, and ability to use the most welding.

Compound Vago - connectors

This connection method is increasingly gaining in popularity, as it is even easier and faster than normal twist. You need only a little to smooth out the wire and insert it in the special clamp, then just snaps it up and voila, you're done.

This method is ideal for the fast and perfect as the entire wiring installation.

Advantages: easy installation, the admissibility of an aluminum compound and a copper (necessary to use specially designed connectors for this purpose), it is permissible to connect the wires of different diameters.

Cons: negative in this case, only one, the price of such connecting elements.

The use of terminal

Connection with the use of the same terminal is extremely simple and requires no effort. Simply to remove the insulating layer on the core, placing it in the terminal slot and to tighten the bolt.

Pros: Easy and quick to install, takes up little space in the control cabinet.

Cons: You can not connect more than two wires to fix the living of various diameters need to purchase specialized terminals. Just such a connection requires periodic revision so that terminal boxes can not be hidden in the wall and need constant access to it.

bolted connection

With the use of small bolts, nuts and three washers, can make quality and very durable connection. This compound has only one drawback, already connected and insulated wires would simply it is impossible to put into the junction box, so that the house is almost no connection use.

pressure test

Such compound has high reliability and quality. On the downside can be attributed only the complexity of the implementation of such compounds.

Here are the main methods of connecting wires, which one to use it in your case, you decide. Thanks for attention.
