From the Equation P=root 3xVxIxP.F. we can calculate the rated current on the secondary side of the transformer. Knowing the value of rated current  we can select the cable size from the cable selection chart.

We have 110Vac ,10A ac supply which is converted into 110VDC & How much DC current? which factor is reqired for dc current calulation?
