This has happened twice so far. About 2 weeks apart. All the touch controlled light in the house flash on and off a number of time , then sty on, a loud buzzing noise comes from the speakers on the computer, one of the outside motion sensor lights turns on, and the GFI breaker, for the swimming pool, mounted in the main panel ,trips. The power going outside from that breaker is turned off at a switch in the house when it trips. None of these lights or the breaker are on the same circuit. This one has me really bewildered.
