Should I use the wiring terminals?

When building any house, sooner or later the question arises as to how to lay the wiring. And if there are no problems with the choice of the thickness of the copper wire, then in the places of its connection it is quite the reverse. After all, using the old method of twisting is unsafe and just unreasonable. But what then? Soldering and welding is a practical option, but very laborious. And if the area of the house is more than 60 square meters, you can solder the cables for a week. What is the way out? The most convenient for today and the most practical way of connecting the wires is to use terminal blocks. We'll talk about them today.

Device and benefits

By design, the wiring terminals (Wago including) are a small plate with holes of a special shape, which have a latch or clamping device. Thus, the cable can move in it only in one direction - inside the device, while bending the plate during a straight stroke. In the opposite direction, such a wire can not be pulled out, which explains the reliability of its use. According to the electricians, modern wiring terminals have a very correct design, so that they can be used both in everyday life and in industry. This is their main advantage over screw terminals.

However, this is not all the pluses of this device. In addition to the reliability of the fasteners, the wiring terminals are simple and quick to install. Their installation is done in a matter of seconds, while soldering requires long expectations of heating the device, great care and accuracy of the work as a whole. Thanks to the use of terminal clamps, the installation, or rather the connection of wires, is the fastest and simplest in comparison with the old methods and methods that were used in the USSR. Of course, the security level of devices such as wiring harnesses is at the highest level.

Connection principle

This tool operates very simply: the pre-stripped cable is inserted into the hole and then pressed with a small spring. Everything, on it the installation of the wiring is completed. 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 possibility of connecting several wires at the same time, consisting of different metal alloys. For example, the wiring harnesses can connect a copper and aluminum wire to each other. In this case, the current carrying capacity of the device will remain at the standard level, without any loss. Such a feature certainly can not boast of welding and soldering. It should also be noted that in the Russian market there are terminal blocks for wiring that can connect up to 8-10 cables at once. On imported devices, it is possible to conduct current wiring through a special device.

How much are the wiring terminals?

The price for such devices is from 12 to 40 rubles per unit.
