There was a cascade of water flowing down the cobblestone driveway. As I approached the four car garage, I noticed steam. I then saw water pouring out of the electrical service panel, that was about four feet long and three feet tall. I then ran back to my truck and got my rubber gloves, rubber boots and my leather gloves. I doubled up the rubber ones and put on the leather gloves before opening that panel. I then saw that water droplets were hanging like grapes. The steam was making the whole panel drip everywhere.
