In which installation the first fireworks will start, differentials will be blown up, etc. ??
The differential does not break down, and the Wago does not flood with concrete. I do not know what kind of installations you create, but I have not seen an installation in a housing run under water ...
Once I found a twisted pair of copper cables in a wall in a block from the 1980s, not even well insulated. Loose insulation made of a thicker cable and plastered into the wall. It has lasted 40 ... the ring years Although this circuit was not spared (also the kitchen). The cables were even a bit loosely twisted together, I don't know if it was because of the passage of time or why, but yes. I fixed it my way, i.e. re-twisting, soldering, heat-shrinking, insulating tape on it and ... well, I didn't want to make a can there ... to the wall and plaster. ROAST ME :)
Ps. Before some of the picaws, Ipz and Riso checked after this game, everything is absolutely normal, it does not go to the senses that this cable was "buried" :)
