This year and last year I started having problems when it rains, causing my Christmas lights to go out, tripping the GFCI.
The GFCI plug is located in the garage, and has all the outdoor covered outlets running through it. The circuit is 20 amps, and I'm running 14 amps of minature outdoor rated lights. There are no frays in the wire and every wire receptable/connection is wrapped with weather proof electrical tape and plastic. I'm using all outdoor extension cords and everything is controlled from 3 heavy duty outdoor timer outlets with covers. I additionally covered the timers with plastic bagging. The timers are connected to the outdoor receptacles on the house, which have plastic bubble cover plates.
I'm stumped as to why everytime it rains, the GFCI trips. Should I lower the amps going to this circuit and divert to another plug on another circuit?
I do have one set of lighting on the left side of the house (about 4 amps worth) that runs to GFCI plug in the house that is on a different circuit breaker. This seems to have no problem when it rains. I'm wondering if I should take about 4 amps off the larger load and add on to this other circuit.
