Good progress there.
I don't think RCD & GFI are quite the same thing
The Residual Current Device trips if the current in each leg differs
The Ground Fault Interrupter trips if current leaks to earth
Now the same fault may well trip either of them, but the RCD will work on circuits without an earth
