TIA 607 Telecommunication Grounding

About this article

Hi guys, few projects here and the TIA standard is in our office spec. using the standard by the book to size telecomm bonding conductors seems ridiculous. "The minimum TBB conductor size shall be a 6 AWG. The TBB should be sized at 2 kcmil per linear foot of conductor length up to a maximum size of 750 kcmil. See table 1. " does anyone know how this determination was made? is the typical workaround to just ignore this, or what? what is typically done in the field? https://preview.redd.it/bcw...
