Selection of cable are as follows-

1) Rated voltage

2) Current carrying capacity

3) Derating factor

4) Voltage drop

5) Short circuit withstand

6) Availability of cables

7) Bending radius

●A power cable in case of short circuit event should be able to withstand the high current value without any damage to the cable & insulation.

●The selection of short circuit current withstand capacity of power cable is directly depends on the specification of connected protection device.

●For selecting low voltage cable short circuit current rating is not important.
