how calculate cable size in squre mm, when the load is
given by in kw? do u have current rating chart of elctrical
cables?
Answer Posted / moh. baheer
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.
