(1) the rated voltage of the cable is greater than or equal to the rated voltage of the power supply system;
(2) the continuous allowable current of the cable shall be equal to or greater than the maximum continuous current of the power supply load;
(3) the cross section of the wire core to meet the stability requirements of power supply system short-circuit;
(4) check the voltage drop according to the cable length;
(5) the minimum short-circuit current at the end of the line should be able to protect the device reliably.
