I think you mean a grund fault interrupter type breaker or receptacle.
The ground fault breakers fit into a regular box and they snap over the HOT input power tab like miost breakers AND they have a white pigtail wire that connects to the neutral bar in the panel.
The branch circuit that is fed from this breaker has BOTH the hot and the neutral connecting to the breaker as the breaker has two terminals for the purpose. The grounding wire of the branch circuit still goes to tthe ground bar in the panel.
For a GFCI receptacle, the branch circuit feeds the terminals labeled "LINE" and if other receptacles are to be protected by this device, they have their circuits continued from the terminals on the receptacle labeled "{OAD".
