Apparently, the times have already passed when the poor fellow-electrician was forced to make a huge number of twists when installing the wiring. This is one of the ways to connect electrical wires to each other. According to all installation rules, such a connection should still be soldered and insulated. The work is long and painstaking, but the result was not the best. If there were a lot of such connections in one place, and even a large cross-section wire was used, it would have been a huge effort to squeeze all the twists into a junction box. Over time, under the influence of an electric current, the contact between the wires disappears.
Anyone who has ever encountered electrical wiring will understand the joy with which we met new terminal blocks for wiring. That is, the terminal blocks as they were before, but they were quite large boxes in which the wire was necessarily attached with a screw. They were used mainly for connecting fixtures. Many of you must have been in this situation: you are standing on a stepladder under the very ceiling, your head and hands are pulled up, and use a screwdriver to twist this small screw in the terminal block. One awkward movement - and this small infection falls to the floor. Well, and what words did you say, getting off the ladder and setting off in search? Today you are relieved of this, because there are wonderful terminal blocks for wiring.
It’s time to tell you more about them. For example, Wago terminal blocks are devices that firmly clamp the wire without a screwdriver.
Outwardly, it is a very small plastic capsule with holes and levers. Their number (from 2 to 8) corresponds to the number of wires that can be connected using this terminal block. The principle of operation is simple. The lever is cocked in a vertical position. The wire is stripped of insulation and inserted into the hole. The lever lowers and clamps it firmly with a spring. The instruction for use is placed directly on the terminal block case in the form of a picture. And if you suddenly found during assembly of the circuit that you clamped the wrong wire into the device, the error is easy to fix: cock the lever again and calmly remove it. The company that produces these terminal blocks for wiring is German, so quality is guaranteed.
The result is a neat junction box. The wire connections are strong and durable, they do not need to be additionally insulated. The terminal blocks do not take up much space, and the entire structure fits easily in the box.
One word is beautiful! And this work takes much less time than when using classical twisting and soldering, and practically no tools are needed. Many human “thanks” to the one who invented the terminal blocks for wiring! The price of such products, depending on the manufacturer, the type of connection and the number of connected wires, can be from 2 to 60 rubles. But my personal opinion is that it’s not worth saving, it’s better to save your strength, nerves and time. Try using terminal blocks for wiring. And feel the difference!
