Basic rule of electricity is W= V*I now wattage would be
the rating of the quipment which remain constant means the
voltage is decrease then current will increase but if
frequency is increase current will decrease now as per this
in foreign the frequency is increase & voltage is decrease
so the required insulation level is decrease. in india the
voltage level is 230 & frequency 50.
