I am on a project that is using the 2008 NEC. The communications riser diagram shows at least (3) locations where a pedestal mount cabinet will be set outside of the building. In each case the designer is indicating a separate ground rod at the pedestal that is not bonded back to anything. Also in all (3) cases, the only cabling going to and from these pedestals is non-conductive (dielectric) fiber. There will be at least (1) branch circuit feeding each cabinet and they will all have active communications equipment in them.
Per Section 770.100(D), I believe these ground rods must be bonded back to the electrical system ground, even though there is no electrical path back to the building via the communications cabling. AM I missing something?
