I have a gfci breaker (murray) protected circuit that trips about once/week. The breaker protects a bathroom lighting circuit that includes 7 compact flourescent lighting fixtures (13 watts each) and bath exhaust fan. The reason to include the gfci is due to the fan requiring the gfci in shower installations. I am unable to cause/duplicate the tripping on demand, but every now and then, the lights no longer work. It is unknown when the tripping actually occurs as I have never witnessed it occur. There is no moisture or humidity problems because the bathroom is not finished yet and is not being used other than the lights.
It has been suggested that the inductive nature of the flourescent compact lighting fixture ballasts may be causing the trips and that I should replace the gfci breaker with a normal one to protect the lights, and rewire the fan into the receptacle circuit, which will provide the gfci protection.
It has also been suggested that the pigtail on the gfci breaker be coiled into a tight loop (I straighted it during installation and the instructions made no mention of a need to retain the loops). Does anyone know if the GFCI breaker pigtail require that it be coiled in the installation? Will a non-coiled gfci breaker pigtail result in nuisance trips?
