A GFCI measures difference in output to return current.
A Overload breaker in your panel is what trips from too much current. many are time delay and will not trip immediately from the less than a second of start up current spike.

Why does your gfci keep tripping after 15 minutesI suspect the circulating motor in my spa.?
The GFCI is sensing stray electricity. Usually, there is no GFCI connected to the pump motor. The GFCI devices would be associated with the air blower, or the lights. If it is the circuit breaker, then there may be a problem with the circulation pump or the circuit breaker itself. A qualified electrician will be able to locate and correct the electrical problem. A pool repair tech may be able to do the same and also correct the problem if it is the motor. Ken
How does a ground fault circuit interrupter shuts down a circuit?
A ground fault circuit breaker detects leakage current between the hot wire coming off the breaker and the neutral/ground since the neutral is bonded to the ground in the panel, if it senses a current of 6 milliamps or more it will trip. Note: no sharing of the neutral for a circuit on a ground fault breaker If a few milliamps from the hot (black) wire do not return on the neutral (white) wire, then a GFCI assumes that current it traveling harmfully elsewhere through your body. So it disconnects. A GFCI can monitor 15,000 milliamps. But if only 5 go missing, then a GFCI trips.
Will an arc fault breaker work without a ground?
Yes a GFCI will work without a ground wire. A GFCI looks for a current differential between current in on the "hot" wire and current return on the neutral wire. Since current is the same throughout the circuit, no difference, no trip. If the load grounds out or shorts out, the current then takes the path of least resistance through the ground and not the neutral. This creates a difference between the "hot" and return neutral current and the device trips the circuit open.
What is a Class A circuit breaker?
A Class "A" Circuit breaker is a Ground Fault Interrupt (GFI or GFCI) breaker ."Class A" marking -- A "Class A" ground-fault device is intended to protect people. The Class A marking indicates that the trip threshold of the GFCI is between 4 mA and 6 mA. This marking may be in any location except the back.
Can you replace an ungrounded circuit breaker with a GFCI circuit breaker?
Yes but it's redundant and may cause unnecessary "tripping" of the circuit. The GFCI circuit breaker is intended to protect an entire receptacle circuit whereas a GFCI receptacle is designed to protect only that receptacle and any which are provided power from its load side. (downstream)
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
What is a gfci oulet?
GFCI=Ground Fault Circuit InterrupterIt's an electronic circuit breaker that compares the current on two wires. If the current is NOT equal, the breaker trips and does so quickly enough to prevent electrocution in the event of a "ground fault".
A GFCI device in a breaker is intended to?
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.

Does anyone make a 100 amp GFCI breaker?
Not that I know of. The largest GFCI breaker I have seen is a 60 amp.
Can a circuit with a GFCI be shared at the box?
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.
How does a GTE Sylvania GFCI circuit breaker 1 pole 15 a work?
A GFCI breaker monitors the imbalance of current between the ungrounded (hot) and grounded (neutral) conductor of a given circuit. With the exception of small amounts of leak-age, the current returning to the power supply in a typical 2-wire circuit will be equal to the current leaving the power supply. If the difference between the current leaving and returning through the current transformer of the GFCI exceeds 5 mA (61 mA), the solid-state circuitry opens the switching contacts and de-energizes the circuit. Touch the neutral or hot and you change this current which will trip the breaker.
Are gfci receptacles required in kitchens?
No, you could use a GFCI circuit breaker instead.
Would a slight rise in the kva cause a 2000 amp gfci breaker to trip?
A circuit breaker trips when the current exceeds the rated trip current. Usually the trip current should be at least 25% more than the maximum expected load current.
Do both the breakers and the outlets need to be GFI if you are running two 15 amp GFI 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.
Is a ground fault indicator outlet installed at the breaker box?
There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.
Can a gfci get weak and trip from over load?
First, lets say this: GFCI stands for Ground-Fault Circuit Interupter. This is NOT an over-current device, and NOT an over-load device. This device stop the flow at 6mA (6/1000 of an amp) of leakage current - current leaking to ground from either the hot or neutral wire. Do you mean a GFCI breaker or a GFCI receptacle?? GFCI receptacles do not "trip on overload". Period. The only over-current protection on a receptacle is provided by the circuit breaker protecting that branch circuit. GFCI breakers are ALSO over-current devices just like normal breakers. And yes, they DO get weak, just like standard breakers do from repeated tripping. They basically have a metal strip inside that gets bent and straightened each time you trip & reset the breaker. All metal gets weak when it gets bent & straightened repeatedly. It is called "metal fatigue".
