    As long as the control voltage is 120 I see no reason the control wiring can't be run in the same conduit as the current carrying conductors. There is nothing that says they must either.

    You can't rely on the coax shield to bond anything. Further, if there were no metallic path back to the house I would say OK but since you do have the coax I would bond it and with larger than #6.

    And perhaps the AFCI manufacturers greed in wanting to expand to a global market will lead to their demise. I have a feeling that the rest of the world isn't as gullible as Americans.
