whenever 2 bodies are connected via a connecting wire, their potential becomes equal...since the potential of earth is taken to be 0....any body which is earthed has its potential equal to 0...

but 0 potential doesn't mean zero charge....

u my consider 3 concentric shells with different charges....connect one of them to earth and then try to find the NEW charge on it using its potential to be 0....u'll not get the charge as 0!
