I really appreciate the efforts put by all.
I would like to throw some light on the matter.

There are three CRITERIA for cable sizing :
The criteria which gives the worst rating is adopted.

1. The maximum short circuit current which can pass through
the cable.
2. The maximum load current which the load can withdraw from
the system.
3. The maximum voltage drop allowed in the system.

Out of these, whichever criteria gives higher rating, that
is selected.

Hope, this satifies the query.

please write motor, transformer, Generator setting, fault level calculation of Tr.etc
