ground conductors)<<

This article from Times Microwave explains it: lightning is a pulse with a
very fast rise time and acts like RF, which means inductance and impedance
come into play. That would explain the surface area reference in TIA code
regarding 2/0 radial conductors. The discussion/diagram on Pg 14 and 15
loosely illustrates the radial/star system that the TIA code describes.

>>No where near a Terajoule of energy.<<

You're right, I don't know where I got that. Should be a gigajoule. Thanks
for correcting me.
