A GFCI outlet has a TEST and RESET switch. Press reset and see if it fixes problem. If reset won't stay in that means that a ground fault condition is present and may be on another outlet that is fed from the tripped GFCI. If this isn't the problem check the main breaker feeding the GFCI and ensure it isn't tripped. If none of this works the GFCI itself may be bad. If you have a Volt Meter you can remove the outlet from the wall receptacle and make sure there is voltage present. You can also see if there is a branch circuit connected. To troubleshoot you can disconnect the branch circuit and then try reset. If you have voltage on input and GFCI won't reset with branch circuits removed, replace the GFCI.
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
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.
Deoends on code you are governed by. In USA, a GFCI outlet or a circuit controlled by a GFCI circuit breaker would be required.
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.
The choice between a 20 amp GFCI and a 15 amp GFCI depends on the ampacity of the circuit you are protecting. A 20 amp GFCI can handle up to 20 amps of current and is typically used for circuits rated at 20 amps or less. A 15 amp GFCI is suitable for circuits rated up to 15 amps. It is important to match the GFCI to the ampacity of the circuit to ensure proper 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.
A GFCI (Ground Fault Circuit Interrupter) is designed to protect against ground faults, not short circuits. Short circuits typically involve an excessive current flow, which is more likely to trigger the circuit breaker in the panel box instead of the GFCI. The GFCI's primary function is to protect against ground faults that could lead to electric shock or fire hazards.
GFCI breakers are typically available in lower amperage ratings, such as 15 or 20 amps. 100 amp GFCI breakers are not common due to the high level of current they need to interrupt. It is more common to use GFCI protection at the branch circuit level for smaller circuits.
If you're using a GFCI breaker then the entire circuit will be protected by just the breaker alone. Every receptacle, switch, etc on that breaker will utilise the GFCI protection. You may have problems with it tripping if you plug in a motor (vacuum, etc) on the circuit.

No, a GFCI outlet is designed for use with standard 120-volt circuits. Attempting to use a GFCI outlet with a 240-volt split circuit could cause damage to the outlet, the circuit, and could present a safety hazard. It is not recommended to use a GFCI outlet in this manner.
In rooms without exposure to water such as a bedroom or living room. Typically, GFCI is used in bathrooms, kitchens, garages, outdoors and sometimes basements.
Yes, GFCI devices are available for use on 240-volt, 480-volt, and 600-volt circuits. They come in different voltage ratings to suit various electrical systems and provide protection against electric shocks by quickly shutting off power if a ground fault is detected. It's important to ensure the GFCI device is rated for the specific voltage of the circuit it will be used on.

Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
