There are many ways to connect wires. They differ in the speed of installation, the quality of electrical contacts, and the ability to operate for a long time under current network loads.
Time-tested twisting with welding has increased reliability. All other technologies are inferior to it to varying degrees.
The article gives advice to the home craftsman on making a welding voltage transformer for connecting copper wires when installing household electrical wiring and a description of the technology for welding them with explanatory pictures, diagrams and a video.
In everyday life, you can find wiring laid using old methods from aluminum or modern ones from copper. Both types can be welded, but since aluminum wires are now reaching the end of their service life and must be replaced by copper wires, we will perform all calculations in relation to the latter.
Wago terminals
Many will probably say: What are Wago-type terminals for? It's the 21st century!
I answer right away: I installed these “super terminals” when replacing the wiring in the apartment, and when I turned on the electric kettle, such a terminal melted, I didn’t like it very much, I even disassembled one such terminal and saw that the contact there was very thin.
Therefore, sometimes the good old twist will be more reliable than all this modern “good”!
At one time, of course, there were good dead-end terminals - you insert a twist into it and tighten it with a screw - it turns out to be insulated and firmly fixed - an awesome thing, but now they have completely disappeared from sale. It's a shame
