Answer / vipin

1)calculate the design current based on the power and voltage
2)identify the distance to be installed
3)identify if there requires any derating factors to be considered
4)select the protection device for the design current ( should be 20% above the design current)
5)select the cable with its apacity higher than the protection device.

(2) and (3) can be ignored for very short distances

Answer / raju

Data not clear, for calculation power or current value
should be required.
