We had an unprecedented flood around here two weeks ago, and ended up with three feet of water in our basement, which had been bone dry for twenty years. Big disaster. But here's my question--even though the water was above the wall outlets for a couple hours, none of the breakers on the panel tripped. Where there were GFCI's in a circuit, they failed. But for example we had an LED nightlight at the foot of the basement stairs, and it remained lit underwater. We never lost power in the house. We had the house electrical service upgraded two years ago--new ground rods pounded in outside and a ground wire added to the main water pipe. The basement outlets were all modern wiring. Can anyone explain this?
