Jim,
Here is what it says. Which really doesn't provide any specific details. But thanks anyway. I guess I need to dig into the Codes for specifics.

What is a Lightning Protection System and what is Bonding and Grounding?
The Lightning Protection System will provide a measure of protection against lightning for your entire structure and many of its systems, including electrical, telephone, plumbing and gas-delivery systems. The Settling Defendants do not believe that a Lightning Protection System is necessary to render their CSST safe. They do agree, however, that such a system reduces the risks to the entire structure and many of its systems, including CSST.

Bonding and Grounding also reduces the risk of damage from a lightning strike. Bonding and Grounding consists of tying together certain systems in a structure that are likely to be energized by a lightning strike to reduce the differences in the so-called “potential” among those systems. This reduces the likelihood of potentially destructive electrical arcing among such systems. For many years, Settling Defendants’ Design and Installation Guides instructed that CSST must be Bonded and Grounded in accordance with applicable codes.
