<big>Agree. But in reality even 00 gauge wire will not dissipate the
charge or handle the current from a direct lightning strike.<br>
The 14 GA wire may, however, allow a light discharge to help prevent
the build up of a much larger charge.<br>
<br>
This is part of the reasoning behind lightning rods, i.e. dissipation
of charge vs direction of a direct strike.<br>
