Answer / gunesh urs k
KA Rating can be calculated by simple Ohm's Law.
I = V/R,
[where R value is calculated by formula ρl/a, ρ=Resistivity
of material of conductor, l=Length of the cable & a=Cross
Sectional area]

Answer / abdul ghouse
Watts = Volts X Amps X p.f.
You can get the AMPS by the Measuring equipements/Meter.
You can take PF = 0.8,
(Power = Work done * Time) Units
