Cable size is dependent upon the load(s) you wish to supply
power too. You have to know the maximum current you can be
expected to carry on a particular circuit BEFORE choosing a
cable.
Once you know the load, you need to choose a cable size
rated to carry at least that much current, preferably more
as a safety factor.
So if you are planning on running several electrical
devices with a combined current of 20 amps, you need a
cable sized to carry at least 20 amps, and slightly more.
To calculate the size of a power cable,pls refer the

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
