Actually, I think I will get my house rewired and will be using an electriction to make sure the building is kept up to code. But until I have the money to do that I want to at least put in a new temporary circuit for just the HT I currently have. I will be splicing into the same circuit that my garage door opener is on. My breaker box doesn't have a ground connection that I can find.

On the other side of the wall, which is outside, the phone line for my DSL is grounded to a pipe, I wonder if I can connect the ground wire from the new line running from the HT to this pipe? Any electrictions that care to comment?
