So, would I be correct in assuming in this case, that it would be "better" to have the strap bond as close to the bottom/foundation as reasonable to reduce the "parallel conductor" distance?In my case, there are threaded steel rods in the foundation, not a tower section...  So the bond would be made to the tower leg that is sitting/bolted in/to a steel clevis bolted to the threaded rod.  I will give additional attention to this inward force to which you refer in the mechanical design.... perhaps a thicker strap and more craftsmanship in the shaping thereof is in order. <wink>.PS - Pretty stinkin' neat to learn something new.... Here's a link that explains the math/theory at a reasonably understandable level.  <smile>http://www.kshitij-iitjee.com/Magnetic-force-between-two-parallel-conductorsThanks Jim!______________________Clay Autery, KY5GMONTAC Enterprises(318) 518-1389On 10/16/2017 11:11 PM, jimlux wrote:>> Remember that parallel currents cause conductors to be forced > together.
