What is the principle of selecting the cross-sectional area of ​​the incoming wire?

The principle of selecting the cross-sectional area of ​​the incoming line is as follows:

(1) Electric lamp and electric heating load: safe cross-section of conductor cross-section (A) ≥ sum of rated current of all electrical appliances.

(2) Only one motor: the conductor safe current capacity ≥ the rated current of the motor.

(3) Multiple motors: Wire safe current capacity ≥ rated current of one motor with the largest capacity + total rated power of the remaining motor multiplied by the required factor.

(4) The minimum allowable cross-sectional area of ​​the incoming line: the copper wire should not be less than 1.5mm2, and the aluminum wire should not be less than 2.5mm2.
