Re: CQD answer published Wednesday, February 15, 2017 -Pole Luminaire Grounding
As related information, it might also be mentioned that a concrete base, even with rebar and/or a grounding rod, is NOT acceptable as the source of the EGC ! The EGC source connection must be from the circuit's power source.
Most AHJs I know would totally accept the EGC being terminated on the metal pole, without also being run up to the luminaire(s).
As a matter of excellent workmanship and forward thinking caution, it is important to install the EGC with a loop of excess length before it is landed on the pole's EGC terminal. This practice will help guarantee that if a pole is knocked down, the supply conductors will break before the EGC does - this helps assure that the downed pole is not live.
