What feature has modern construction? How the assignment of the premises affect the work of an electrician? What to do if there are doubts?
Construction requires station wagons!
Not so long ago, so to speak, looking around construction work, it was possible to accurately determine which part of the work by which specialists would be performed. Today everything has changed so much that, firstly, the need for the station wagons, that is, those who owns two or more specialties has sharply increased. And secondly, in order not to do troubles, any specialist must at least approximately imagine what is happening in neighboring, so to speak, border areas.
For example, if you take a modern electrician, then he must understand which devices will be used in a particular room to properly put the wiring. Because, say, a diode bridge with a capacitor, which is an element of one of the popular electronic devices, behaves not like the same bridge, but without a capacitor, but without a condenser!
When doubts arise ..
No, no one declares that qualified electrician should know, say, the same diodes catalog. No, this is, to put it mildly, too much. In the end, with the development of the Internet, and the cheapness of mobile devices, you can always, if doubts arose, go to the site and clarify the details you need. But in order for these doubts to arise, basic knowledge must be had? It is necessary to imagine that it is dangerous for a microwave, a washing machine, a computer, a server and similar devices.
What is needed for this? Trite, but more read. Good, smart books.
