When installing an electrician, the owners make a mistake, which they later regret. There is a simple solution
The rugged owner is quite capable of installing new wiring on his own during repairs. All the incomprehensible moments can be spied on the Internet, the topic has been worn out along and across, the information is quite accessible and chewed by professionals. Only one important point is missed everywhere, which will later become a real headache. What I mean, now I will explain.
Situation after renovation
The electrics are done, the repairs are finished, everything is cool, but two years have passed and we need to hang a new shelf, a TV set and the like and... So, where did we throw the wiring? Around here, hmm, or maybe here, no, just here, damn it. Familiar situation?
A simple solution
Faced with this more than once, when you ask the code during installation, where is the wiring, the owner shrugs his shoulders. So this time I saw the grooves with wiring, took a tape measure and a pencil and applied the dimensions, photographed, threw the files. That's it, the problem is solved.
Scheme
Better yet, make a skeleton diagram for each room, multiply and save them in different places. Then guessing on the coffee grounds will disappear, where to attach the anchor. Some will argue that there are installation rules, where and at what distance the wiring should go. But they are not always respected.
Advice
Even if a professional does the wiring for you, ask to make a circuit, of course, it will cost additional money, but it will pay off later.
