Specialty:
Yes, welcome to ECN, and I have to say 'scuse me for omitting that above.
Again, PVC is my choice, but IF RGC, I would still install an EGC within the RGC.
I've seen quite a few specs recently for PL lighting with 3/4 x 10' rods (2) at each 'base', sonotube or pre-cast, and 'Cadweld" termination. The EE's say lightning protection, and a "redundant grounding system". I just assure that it is all bonded together, and 'to spec' in addition to NEC compliance.
