I have a project where we are upgrading 11 Water Agency SCADA sites. The sites are pumping stations for well water and have utility supplied electrical services with MCCs. The design calls for 20' of #4 cu wire and a ground rod to be installed in the concrete pole base and attached to the grounding post in the antenna pole handhole. I asked the question to the PE as to whether the grounding electrode of the new antennas should be attached to the grounding electrode system of the existing on site electrical service per 810.21. The answer was no "because there is no building (structure) on site there is no need to connect the grounding systems per 810.21." I say the Service Panel and MCCs are a structure and the grounding stystems should be connected per 810.21. What do you think? Not that I will change the PE's mind but just want a second opinion.
Thanks
