Are any of the outlets OUTDOORS? If so, and if an outlet is getting wet, it will trip the GFIC immediately.
If that's not it, unplug everything, reset the GFI and see what happens. If it still trips, make certain that the wires aren't getting wet somewhere.
If THAT'S not helpful, replace the GFI.
A GFCI will not trip if there is no load applied. First check to make sure that the test button is not stuck in and not releasing. If the test button is OK then check downstream from the device. If it is a GFCI breaker then any load device on the circuit could trip the circuit. Determine where the circuit goes and how many receptacle outlets are on the circuit. Unplug all of the circuit loads and try to reset the breaker. If the GFCI is a receptacle keep in mind that every receptacle down stream from that receptacle is also protected. Go through the same procedure as with the breaker on checking the circuit. If you have an electrician friend ask him to do a megger test on the circuit to locate which device load is At Fault.
The trip time for a GFCI is from 15 to 30 milliseconds.
A GFCI is not an overcurrent protection device. It only protects people from electrical shock. However, if you were to create a perfect hot to neutral short the GFCI would not trip and the panel breaker would.
GFCI receptacle are designed to trip on 5 milliamps.
The GFCI is measuring leakage current to ground, so if no current is flowing it won't trip.
There is three possible reasons for this. First, check to make sure that the breaker also did not trip, a GFCI outlet will not reset if not powered. Second, if the load that caused the GFCI to trip is still plugged in it will not allow the GFCI to reset. So, before trying to reset the GFCI unplug everything that it protects. Third, you might just have a bad GFCI, attempt the above suggestions first and if it still will not reset you will need to replace the GFCI. If after all this the you are still having problems then something more serious is wrong and you need an on site electrician to diagnose the problem.
Because something is wrong. Check for shorts and, if it is a GFCI, also check for ground faults and leakages. It is also possible, in the case of a GFCI, that an inappropriate load, such as a computer monitor or UPS, is connected. These devices pull transient power to ground and will trip a GFCI. Do not ignore the situation. The protective device is tripping for a reason.
A down stream receptacle that is connected to the upstream GFCI will be protected. If the downstream receptacle senses a fault the upstream GFCI will trip.
The trip time for a GFCI is from 15 to 30 milliseconds.

GFCI receptacle are designed to trip on 5 milliamps.
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.
Every time you trip the GFCI, the power to the device plugged into it will lose its supply voltage.
it is not wise to remove this device it is in place for your safety it is also wise to note over time these device do false trip for no reason.Some will trip with an induction load like a fridge . have it tested .........................
GFCI Breakers are quite a bit more expensive than a GFCI outlet. More often than not a typical residence will need only a handful of GFCI outlets that combined together will be cheaper than a GFCI breaker. If you need to protect a series of outlets with GFCI protection you can simply connect the rest of the outlets on that same circuit downstream from the first outlet on the line and make that the GFCI. All you have to do is connect all the other outlets to the LOAD side of the GFCI outlet. If a GFCI fault occurs in any of the outlets down stream they will trip that very first GFCI plug you placed and keep you safe.

If it is a line thermostat and it is connected across the line instead of in series with the load then yes it will trip the breaker.
