How to connect 3 Current Sensors to 1 arduino


I am working on a project of home power monitoring,

I have the Current Sensor mentioned in this site and i have also used this diagram mentioned in this site.

But the problem i have is that i have to read current of 3 different wires but according to this diagram i think they will all give me the same result can anyone help please??


why would they give you the same result if you read wires to a different loads?
