( Industry news] Introduction to wire and cable cross-sectional area and the relationship between the power rating sanewcable P the use of wires, cables, related to the current, voltage, and is associated with the material quality of itself, and also choose wire ( Cable) The cross section of engineering allowance. So, it is A very flexible, for example, for A carrying capacity of A circuit, you use cross section. The mm square ok, use the mm square? Use the mm square? Even use. The mm square line ah. Can, is not is have to which section. Can say which is more reasonable, more appropriate. For example: per square A calculation, it can't say for sure! Small current carrying capacity, the calculation is ok, more than A carrying capacity, are you still in this way, will be out of things. Is to, first of all know in the circuit carrying capacity ( Rated current) And then, to consult the cable ( The conductor) Vendors to allow long-term continuous working current index, can be greater than or equal to, of course, should also be multiplied by a coefficient, a few be engineering allowance. http / / www。 sanewcable。 com
