yet another gfi question

My hot water heater is not grounded. I am running the new 10-2 w/G today, and was told to run the ground wire to the grounding screw on top of the W/H. But There is a cable clamp to clamp the romex into,(at the top of the water heater)then wire to the 220 V terminals. Now for the ground, should I run the romex into the clamp, then bend the grounding wire back up(180 degrees) and through the clamp to be able to attach it to the grounding screw on the top? It is an A.O. Smith Model ees 40 913 if that helps. Thanks, Tony D.

I just purchased a house and when I moved in the door bell did not work. I went into the basement and found the wire that runs to the buttons (front door, and side door). I then followed the wire to the circut breaker. The wire was hanging above the circut breaker not attached to anything :( There were two screws on the side of the circut breaker that also had no wires going to it and from the position of the wire hanging this was a very logical solution. I screwed the wires to the screws and I had a working door bell! :D .... well until last week. :confused: After visitors kept knocking on the door I tried the door bell to see why no one was using it. The button is still lit up but when you push it, the bell does not ring. The wires are still connected in the basement. So... two questions... 1. Why would you suppose the wires were disconnected in the first place? 2. Why would the bell stop working now?. Thanks for any replies, they are much appreciated!
