I have noticed that my gfci outlet has been tripping and I couldn't figure out why. This outlet is connected to my landscaping light controller as well as my pool timers and accesories. Everything seems to work just fine when I turn the waterfall on and/or the pool light. But as soon as I turn on the hot tub light the outlet on the side of the main pool switches trips and none of the accessories work. So I have to reset the outlet. Any ideas on what could be causing this?
