[TowerTalk] Mot R36 related to NUMBER of installed ground rods

[Jeff]

I’m laying out the ground rod scheme for the towers.  

As I look at Mot R56, it seems like about 45’ of rods gets you to the 5 ohm target based on one of the graphics they provide  That’s about 9 ground rods spread out in 3 legs each with 3 rods separated by 16’ assuming 8’ rods and average soil.

While I realize more is better, how do you determine “enough” in the context of ground rod count?
