Lightning has nothing to do with this.

Mike:

The equipment grounding conductor in branch circuit wiring has nothing to do with lightning or protection from lightning. Nothing in the entire grounding scheme of typical NEC-minimum residential wiring practice does.
Exception: External radio-television-ham antennas must have grounded discharge units. Maybe there are some other obscure things I don't know about...

If anyone is in a lightning prone area (see link below), I'm sure between the local utility and/or building codes, that there are measures taken or required for an air terminal system ("lightning rods") and/or a TVSS at the main panel. I vaguely recall your neighboring utility to the north (SMUD) was installing these for free. A residential TVSS is a Good Thing, and for reasons other than lightning.

I'd commend reading the Steve Eddy post below for a description of the purpose of the equipment grounding conductor in branch circuit wiring.

I'd also run the cited Code sections by your installing electrician -or the company he works for- all licensed and bonded no doubt, and get his reaction. Just for a second opinion...
