I've tried to research the below and I believe the answers you
received regarding ANSII and IEEE specs are probably the best.
All my documents require #2AWG or larger for tower grounding
conductors, but I find no mention of any regulations requiring it.
The only real hard requirement seems to be for a .01 ohm ground.
