I can not say that "it states that" in any one place.
You got to jump around.
Grounding Electrode Conductor. The conductor used to connect the grounding electrode(s) to the equipment grounding conductor, to the grounded conductor, or to both, at the service, at each building or structure where supplied from a common service, or at the source of a separately derived system.
Service Conductors. The conductors from the service point to the service disconnecting means
Now take a look at part of 250.50
If available on the premises at each building or structure served, each item in 250.52(A)(1) through (A)(6) shall be bonded together to form the grounding electrode system.[/b]
Bonding jumpers are used to bond the electrodes together into a grounding electrode system.
Once you have made this grounding electrode system the conductor from any point in this system back to the service disconnect is the grounding electrode conductor.
