How to distinguish between power cables and electrical wiring on drawings

How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more

Answer:

The second floor of the formula is correct, my space also have this formula, with armor and no armor in the current no difference, there are differences in the installation, usually buried to armor, overhead or bridge without armor, you give the model is not Armor, YJV-4 * 240 without armor, YJV-22-4 * 240 armor,
Can not be removed, and so on after the first line of fluoride, and then demolition of air conditioning.
After the opening is not, if not open like a downstairs to delete the C disk file on the line, if the boot is necessary to set up, sit down little hands and feet.
According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.
