I would like to run a ground wire in conduit(with other conductors) to a surge protected device.How can I go from the conduit to a plumbing ground clamp?

Rez...how would the codes differ depending?
If I run the #8 in PVC conduit (for protection),I am OK?

Here is the code references;
ARTICLE 285 Surge-Protective Devices (SPDs), 1 kV or Less
285.28 Grounding Conductor Connections and Enclosures.
Except as indicated in this article, SPD grounding connections shall be made as specified in Article 250, Part III. Grounding conductors installed in metal enclosures shall comply with 250.64(E).
250.64(E) Enclosures for Grounding Electrode Conductors. Ferrous metal enclosures for grounding electrode conductors shall be electrically continuous from the point of attachment to cabinets or equipment to the grounding electrode and shall be securely fastened to the ground clamp or fitting. Nonferrous metal enclosures shall not be required to be electrically continuous. Ferrous metal enclosures that are not physically continuous from cabinets or equipment to the grounding electrode shall be made electrically continuous by bonding each end of the raceway or enclosure to the grounding electrode conductor. Bonding shall apply at each end and to all intervening ferrous raceways, boxes, and enclosures between the cabinets or equipment and the grounding electrode. The bonding jumper for a grounding electrode conductor raceway or cable armor shall be the same size as, or larger than, the enclosed grounding electrode conductor. Where a raceway is used as protection for a grounding electrode conductor, the installation shall comply with the requirements of the appropriate raceway article.

Along these lines,if I were running multiple wires thru PVC conduit for physical protection,then had the PVC conduit terminate into say,an 8X8 metal box containing (3) 12/2, (2) 10/3,and (1) 8/3,all Romex...What grounding would be required for the metal box?
This is awkward, but...
