instruments are designed of this range and another use of
this current is to operate the protective relay.

Actuality I have at home electrical panel with 220v 50hz, and I want to converter from there to 110v 60hz, to wiring on the half of my house. Also I like to keep another half of my house with the original 220v 50hz. What is the best and safety way to do?
