Re: GFCI breaker tripping
GFCI measure the difference in current between Hot and Neutral. If difference exceeds about 5 ma (5/1000 ampere) device trips.
How much other stuff is on the GFCI protected circuit? 5 ma is not very much current. Want to check all receptacles and switches on circuit. If there is corrosion need to be replaced.
If everything downstream of the GFCI looks good agree with SparkChaser  probably a problem with GFCI under with certain types of loads. Try replacing it.
Another option it to replace GFCI breaker with regular breaker and use GFCI outlets as needed. If breaker is being used to protect other areas that require GFCI, such as bathrooms, will need to install GFCI outlets in that location also. You don't need one at every location. Anything downstream is protected, just like using a breaker.
When I first built our house used GFCI breaker to protect outside receptacles and lighting. Was plagued with nuisance trips. Replaced breaker and installed GFCI outlets at front and rear of house. Have not had any more problems.
