Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
A GFCI receptacle can extend its protection to regular receptacles connected to the output side of the GFCI. Each actual GFCI receptacle should be directly connected to a breaker in electric panel.
Yes. NEC 2005 440.21
You need a GFCI outlet at any location that is within 6' of a water source. You also need a GFCI outlet in a room with a concrete floor, any garage, and any location outside the home or under the home in the crawl space. A GFCI outlet protects you from electrical shock near water or moisture. You can protect more than one outlet with 1 GFCI outlet. Connect the incoming power to the LINE side of the GFCI outlet and all the other outlets getting power from that outlet to the LOAD side of the GFCI outlet. That way they will all be protected by 1 GFCI. A GFCI breaker is used to protect an entire circuit and not just individual receptacles. It is often cheaper to use GFCI receptacles than a breaker, especially if "piggy-backed" such as described above. It is also more convenient to reset a GFCI receptacle than to reset a breaker. But your question is "why." From this I suspect you may be misunderstanding the difference between a breaker and GFCI protection. To keep things simple let me say that a GFCI does not work on the same principles as a standard breaker. It provides a much safer protection than a standard breaker. Even with a ground you need GFCI protection as listed above.
Most definitely. GFCI receptacles have a test buton, and should be tested regularly. you can also buy inexpensive plug-in testers at most home centers and electric supply houses.
When a GFCI-protected extension cord is plugged into an outlet that is also GFCI protected, it provides an additional layer of protection against electric shock. Both devices work in conjunction to quickly detect any imbalance in the electrical current and trip the circuit if necessary. This redundancy helps ensure increased safety against electrical hazards.

Yes you can. Lots of blow dryers have GFCI protection built in.
A Ground Fault Circuit Interrupter (GFCI) is designed to sense short circuits and stop electrical flow when ground faults occur. They work by quickly disconnecting power to prevent electric shocks and protect against fires.
A GFCI receptacle can extend its protection to regular receptacles connected to the output side of the GFCI. Each actual GFCI receptacle should be directly connected to a breaker in electric panel.
It is recommended to have GFCI protection for all electrical outlets in a garage to help reduce the risk of electric shocks. This would typically involve installing a GFCI outlet at the beginning of the circuit to protect the rest of the outlets downstream.
Yes, it is recommended to have Ground Fault Circuit Interrupter (GFCI) protection in a kitchen. GFCIs help prevent electric shock by quickly shutting off power in the event of a ground fault or short circuit. They are typically required for outlets near sinks, countertops, and areas prone to moisture.
No, a two pole GFCI breaker must be wired to both hot wires of a circuit in order to function properly. Using only one side will not provide the necessary ground fault protection.
A Ground Fault Circuit Interrupter (GFCI) should be installed in areas where water is present, such as kitchens, bathrooms, outdoor outlets, and garages. It is important to have GFCIs near sinks, showers, and other water sources to prevent electric shocks.
Currently, there is no manufacturer that makes a main breaker 200 amp service with built-in 200 amp ground fault circuit interrupter (GFCI) protection. GFCI protection is typically provided through individual GFCI outlets or circuit breakers installed within the electrical system.
A surge protector is generally better for protecting against power surges and voltage spikes in electrical devices, including GFCI outlets. GFCI outlets are designed to protect against electric shock in wet conditions, such as bathrooms or kitchens. It is advisable to use both a surge protector and GFCI outlets for optimal protection.
A GFCI can detect ground faults on the specific circuit it is connected to. If multiple outlets are on the same circuit protected by a single GFCI outlet, the GFCI can protect all of them. However, if the outlets are on different circuits or not downstream from the GFCI, they would need their own GFCI protection.
