Rule 59.4-A1
59.4-A1) Grounding Conductors: The grounding conductor from each ground electrode to the base of pole shall be not less than 1 foot below the surface of the ground and shall have not less conductivity and mechanical strength than the grounding conductor from the base of the pole to the common neutral line conductor. The grounding conductor to the common neutral line conductor shall be continuous unless suitable electrical compression connections are used and shall be not less than No. 4 AWG cooper.

Rule 59.4-A1
59.4-A1) Grounding Conductors: The grounding conductors of the common neutral system shall conform to each of the following requirements:
a)
The grounding conductor from each
ground rod electrode to the base of the pole shall be
not not be less than 1 foot below the surface of the ground.
b)
and The grounding
conductor from each ground rod to base of the pole shall not have not
less ampacity conductivity and mechanical strength than the
grounding conductor from the base of the pole to the common neutral line
conductor.
c)
The grounding conductor from
the ground rod to the common neutral line conductor shall be
continuous unless suitable electrical compression connections are used
d)
and The grounding
conductor shall be not less than have a minimum ampacity
equivalent to No. 4 AWG cooper.
