    Default Grounding electrode conductor size for copper

    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.
