So my 7 year old son I are working in our finished basement room last night. He's helping me install some wire for a switch above my drop ceiling in my office. We've got a few tiles moved and the wire stapled up. I went to the garage to get my fishtape and I hear the sounds of a crash.The main in the grid wires came off the hook and brought 12-15 tiles and bars down with it including one lay-in light sitting on the floor, romex still connected. Yes, Yes, I know the light is supposed to be independently supported and the grid wires through holes not hooks.I called the builder and electrician to complain and get it repaired. It doesn't work so well when I am both. This will be a fine example of doing it right the second time.
