When building any house, sooner or later the question arises of how to lay the wiring. And if there can be no problems with the choice of the thickness of the copper wire, then in the places of its connection it is quite the opposite. After all, using the old method of twisting is unsafe and simply unreasonable. But what then? Soldering and welding is a practical option, but very time-consuming. And if the area of the house is more than 60 square meters, you can solder the cables for a whole week. What is the way out of the situation? The most convenient and most practical way to connect wires today is to use terminal blocks. We’ll talk about them today.
Device and benefits
In their design, the terminal blocks for electrical wiring (including Wago) are a small plate with holes of a special shape that have a latch or clamp device. Thus, the cable can move in it in only one direction - inside the device, while bending the plate during forward movement. In the opposite direction, such a wire cannot be pulled, which explains the reliability of its use. According to electricians, modern terminal blocks for electrical wiring have a very correct design, as a result of which they can be used both in everyday life and in industry. This is their main advantage over screw clamps.
However, this is not all the advantages of this device. In addition to the reliability of the fasteners, the terminal blocks for wiring are simple and quick to install. Their installation is carried out in a matter of seconds, while soldering requires long expectations of heating the device, great care and accuracy of work in general. Thanks to the use of terminal clamps, the installation, or rather, the connection of wires, is the fastest and easiest compared to the old methods and methods that were used back in the USSR. Of course, the safety level of devices such as terminal blocks for wiring, is at the highest level.
Connection principle
This tool works very simply: a pre-stripped cable is inserted into the hole and then pressed by a small spring. That's it, the wiring installation is complete. Indeed, this design greatly simplifies and speeds up the process of laying the cable in the house.
Versatility
Another important feature of the terminal blocks is their versatility, which consists in the ability to connect several wires at once, consisting of different metal alloys. For example, terminal blocks for electrical wiring can connect a copper and aluminum wire. In this case, the current transmission of the device will remain at a standard level, without any loss. This feature certainly can not boast of welding and soldering. It should also be noted that on the Russian market there are terminal blocks for electrical wiring that can connect up to 8-10 cables at once. On imported devices, the possibility of continuity of conductive wiring using a special device is provided.
How much do terminal blocks for wiring cost?
The price of such devices is from 12 to 40 rubles per unit.
