Electrical Wiring in the Home/Double GFCI Breakers



I have a line that runs from the circuit breaker cabinet to the exterior to plug in a sump pump.  The line runs from the cabinet to the exterior of the house where there is a GFCI outlet.   From this point the line drops down out of the receptacle box travels underground to a post in the yard where there is another receptacle near the sump pump (non-GFCI).  The electrician installed a GFCI breaker in the breaker cabinet and there is also a GFCI on the side of the house.  The breaker keeps tripping even when the sump is not plugged in.  Could the double GFCI's be causing the problem??

Thanks for the help.

It sure sounds like the double GFCI is the problem I am not sure but you do not need two GFI's for anything so I would get rid of the one that's tripping (literally) and hopefully that will clear up the problem. Do not hesitate to contact me if you need more help....Curt dog
