[Earthing wire] not inside any metallic conduit

Why would this be? Sometimes it might be necessary to use metallic
conduit to protect the earthing wire from physical damage.

Same rules also apply to cable TV and AC mains earthing wire. All
earthing wires should remain separated until all meet at their common
earthing electrode.

Given that the main panel/disconnect will have a grounding bar where
the Grounding Electrode Conductor terminates, is it good practice to
run the cable TV and telephone earthing wires directly to this grounding
bar?
