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.
Using a GFCI breaker with a GFCI outlet is important for electrical safety because it provides double protection against electric shocks. The GFCI breaker monitors the entire circuit, while the GFCI outlet monitors just that specific outlet. This combination helps prevent electrical accidents and protects people from potential harm.
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.
Installing a GFCI outlet and GFCI breaker can help protect your electrical system by quickly shutting off power if there is a ground fault, reducing the risk of electric shock or fire. This added protection can help ensure the safety of your electrical system and prevent potential hazards.
Yes, it is necessary to install a GFCI outlet in the bathroom for safety reasons.
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 GFCI outlet provides localized protection by monitoring the flow of electricity in a specific outlet, while a GFCI breaker protects an entire circuit by monitoring the flow of electricity in the entire circuit. Both devices quickly shut off power if they detect a ground fault, which helps prevent electric shocks and fires.
