The selection of power cables should follow the following principles:
1. The rated voltage of the cable is greater than or equal to the rated voltage of the power supply system at the installation point;
2. The continuous allowable current of the cable should be equal to or greater than the maximum continuous current of the power supply load;
3. The cross section of the wire core meets the short-circuit stability requirements of the power supply system;
4. Check whether the voltage drop meets the requirements according to the length of the cable;
5. The minimum short-circuit current at the end of the line should make the protection device reliable.
