Default NEC Rules on Grounding Electrode Conductor(s)
On 2007-04-25, wrote:

The GEC is actually a transmission line, designed to handle high
frequency transients. An ungrounded metal conduit will act as a
choke and slow down the sheadding of this transient. The raceway may
actually carry more of the transient than the conductor. That is why
you see "city" hubs connecting the raceway to a ground rod.

Indeed, that is why I am going to be using PVC conduit.

Cheers, Wayne
