Your grounding electrode conductors go the main disconnect, not to the sub
panel

Hello,

I'm replacing my exterior main panel with an exterior main disconnect
serving an interior subpanel, so I have a couple questions on
grounding at a residential electrical service entrance.

First, is it OK to run Grounding Electrode Conductor(s) inside the
same 2" PVC conduit as the #1/0 Al SER cable feeding my subpanel? Or
do they need to be separated? I have one conductor from a Ufer
ground, and another conductor going to the copper water service and a
ground rod.

Second, I understand the telephone and cable services need to be
grounded. They presently have individual little ground rods, so I
assume it would be better to interconnect them with the electrical
service grounding system. Is it better to do this inside the
electrical service entrance (at the ground/neutral bar), or outside it
(at the closest Grounding Electrode Conductor)?

Thanks,
Wayne
