Yes, there are several ways to wire them. If you only want some plugs to be GFI (only the actual GFI plugs) protected then you wire them using just the "load" screws. if you want the whole circuit to be protected (or just two separate portions) the GFI plug must be first in the circuit and the protected plugs wired off of the "line" screws on the receptacle. Check the instructions, local codes, and with an electrician of course. Be safe, GFI circuits can be tricky.

Why and when would you use a GFCI breaker within a older home with a groun?
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.
How do you install an electric pool pump I've already hooked up the wiring and it's been working fine for three month's. Then the breaker tripped now it keeps tripping when I try to turn pump back on?
=== === Any socket outlets or wiring to pumps, etc must be protected by a GFCI, not only by the main circuit breaker on the house AC power supply panel.Sounds like there is water somewhere in the circuit and that is causing the GFCI to keep tripping every time you press the RESET button. The GFCI is doing its job to protect you and your family from electrocution.Turn off all power at the main panel and then check all wiring, junction boxes, outlets, etc. in the circuit for water. Every part of the circuit must be allowed to dry thoroughly before the GFCI will allow you to reset it. Then be sure to protect any connections in the circuit from getting any water spray or splashes in future.Really this work should be done by a licensed electrician who will know exactly where to check and what to do to make your electric pool pump - and any socket outlets in the same circuit - safe to use in future.Is the distance from the panel to the pool very far or long, A ground fault breaker is looking for a difference in potential the longer the distance the more sensitive they become. What you may have to do is put a ground fault outlet by the pump and put the wiring in a regular breaker. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicator to insure the circuit is, in fact, de-energized.
How many wall outlets can you have in a circuit using a A breaker?
Assuming this is not an office of a place where lots of the outlets will be used to power items that draw lots of current on a 15 amp circuit wired with 14/2 wire I would limit it to no more than 10 outlets and lights combined. On a 20 amp circuit wired with 12/2 wire I would limit it to a 14 outlets and lights combined. There is no limit in the code. You just use common sense based on what is going to be used on this circuit.
How many outlets are there?
Up to 12 on a 20 amp circuit. Up to 9 on a 15 amp circuit. But use common sense. If the circuit will be heavily loaded, as in a home office, then do not install that many.
Can you use a 240 volt 40 amp GFCI circuit breaker for a stove?
Yes you can but the electrical code does not require it. To use one where it is not requested to do so is just adding to the over all expense of the project.
