Proper ground attachments.

What is the best way to attach all of my grounds together? I need to bring my cable and telephone grounds to the same point as my service ground. Should I do this in the service panel, at the acorn clamp, or some other way?

The shortest and most direct is best. Probably a split bolt connector on the conductor actually going to the grounding electrode.

In National Electrical Code parlance this is referred to as "Intersystem Bonding". Art 250.94 requires such terminations be made at , and external to , the enclosure of the Service Panel. Available are Bonding terminations designed for this specific purpose.

Thanks guys. I actually ordered one of the Arlingtons. I'll probably see it on Monday.

I did go out and inspect my ground wire and electrodes. The one clamp was loose so I tightened that up.
