To understand what is specifically drawn on a diagram or drawing, you need to know the decoding of those icons that are on it. This recognition is also called drawing reading. And to facilitate this lesson, almost all elements have their own conventional icons. Almost, because the standards ...
For monthly payment for consumed electricity, it is necessary to transfer data to the subscriber service or independently make calculations. In any case, it is necessary to take the readings of the electricity meter, and then take the appropriate action. How to do this - we will consider further.
In theory, the diameter of the conductors should correspond to the declared parameters. For example, if it is indicated on the marking that the cable is 3 x 2.5, then the cross-section of the conductors must be exactly 2.5 mm2. In fact, it turns out that the actual size can differ by 20-30%, and sometimes even more. Than ...
When laying electrical wiring, you need to know which cable section you will need to lay. The choice of the cable cross-section can be done either by the power consumption or by the current consumption. You also need to take into account the length of the cable and the method of installation.
