About a week ago, a GFCI tripped. I noticed that because appliances in my kitchen stopped working. The short story is that something was put into an outlet that shouldn't have been. That's not the issue. My son went to put some stuff in the deep freezer in our garage today and discovered that the freezer was out and that we had some rotting food. My question is, why did a GFCI in my kitchen and in my garage trip? When one trips, do they all trip? Did the added strain of a foreign object in an outlet cause them all to trip? Was it just a coincidence?
Second question. What's the best remedy for this? Should I swap out the GFI or try to do some sort of alarm?
