[RE-wrenches] Grounding DPW MPM.

[Darryl Thayer]

I did one very similar in western Minnesota, high sand soil in an area that has a fairly high lightening strike count,  I ran the equipment ground back along with the conductors, I also used an 8" post hole digger with an extension to go down 5 feet, filled it with concrete around the 1.5" galvanized pipe legs and it is about ten feet high to top of modules, the lightening ground is the concrete incased electrodes,  This is a UBC 90 mph area, it is still there and working after more that 10 years.  So you always always need a an equipment ground, and I could have put a ground rod in but the concrete encased electrode is just fine.

Hello,

I have been looking at ground mount methods lately, specifically the DPW Multi-Pole-Mount setup and was wondering about the method used to ground the modules and racking.  How is this done?   



Thanks as always!
