I'm with Sean...I would also add to my previous post that if there is CATV involved some where in the system to use a g round breaker for it instead of tyring to make the ground common.
dedicated lines. what goes where?
Dedicated (meaning separate?) grounds that run to different ground rods...sounds like the beginning of trouble (ground loops, hum...etc). The whole idea is to have a single, common ground in a system. If each is at a different, even slightly, potential (voltage) you will have current flow through the ground causing who-knows-what... When all of the grounds are common (as in most all electrical wiring and systems), by definition they are all at the same potential (voltage) and no current will flow.
If you read through some old posts, you will find those reporting improved performance after opening up the electrical panel and re-tigtening all the ground and common line connections. Many connections leads to contact resistance. The resistance causes voltage drops and that causes unwanted current flow.
All grounds should be common and this include cable TV connects if that's any where in your system. Multiple ground rods are good, just tie them together with 10 gauge solid wire and make sure all connections are tight...
