If I have four seperately derived systems (transformers) each having 3/0 copper secondary phase conductors, do I need to take into account note 1 on table 250-66 when sizing my grounding electrode conductor. If so could someone please explain the steps. Thanks.
I am new to this forum and am still learning my way around it so please be patient.
