220, 50 HZ was used by the British and India too followed it just like in Europe. The Americans being different as usual chose 110v 60 HZ for domestic supply. The 110 v was for safety from getting a shock, but the 60 HZ equipment will have more eddy current losses but for 3 phase the synchronous speed of the motors will be higher.
