Grounding electrode conductor size for copper

[Wendell Swedberg]

Refer to table e3503.1, note d.

Note d states,

Where the sole grounding electrode system is a ground rod or pipe as covered in Section E3508.2, the grounding electrode conductor shall not be required larger than 6 AWG or 4 AWG aluminum..

So, If you have a single ground rod, the minimum grounding electrode size is 8 AWG (from the table), correct? Note d is only saying, "not required to be larger than 6 AWG?

Wendell,

Since #6 is not larger than #6, it seems to me that the grounding electrode conductor should be #6.

Wendell,

Review this other thread of yours ... http://www.inspectionnews.net/home_inspection/electrical-systems-home-inspection-commercial-inspection/7299-single-grounding-rod.html ... it is the same question, just asked differently.
