We can so easy calculate the current and choose the cable
size form chart if we have the quantities of Voltage (Volt)
and total power (KW) please find from this formula the
current rate according to the load (kW).
P = U*I*cosФ
I = P/U =?
Then we can choose the cable size from chart according to
current.

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
