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.
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
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.
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.
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.
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)
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
To install a GFCI breaker, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker you want to replace with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
Yes, it is recommended to have both GFCI outlets and a GFCI breaker installed for maximum electrical safety in your home.
To install a GFCI breaker in a circuit, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the circuit breaker that needs to be replaced with the GFCI breaker. Disconnect the wires from the existing breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
To properly install a GFCI breaker in your electrical system, first turn off the power to the circuit you will be working on. Remove the panel cover and locate the circuit breaker you will be replacing with the GFCI breaker. Disconnect the wires from the old breaker and connect them to the new GFCI breaker according to the manufacturer's instructions. Secure the GFCI breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
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.
To replace a GFCI breaker, first turn off the power to the circuit at the main electrical panel. Remove the panel cover and locate the GFCI breaker. Disconnect the wires from the old breaker and remove it. Install the new GFCI breaker in its place and reconnect the wires. Secure the breaker in the panel and replace the cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
The recommended type of breaker to use for a hot tub that requires a 50 amp GFCI breaker for safety is a 50 amp GFCI breaker.

The recommended type of GFCI 50 amp breaker for outdoor electrical installations is a weather-resistant GFCI breaker.
To install a GFCI breaker panel in a residential electrical system, follow these steps: Turn off the power to the electrical panel. Remove the cover of the electrical panel. Identify the circuit where the GFCI breaker will be installed. Install the GFCI breaker in the panel according to the manufacturer's instructions. Connect the wires to the GFCI breaker, following proper wiring techniques. Secure the breaker in place and replace the panel cover. Turn the power back on and test the GFCI breaker to ensure it is working properly.
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.
