OK, some practical considerations then.
If I bond to the power meter on the exterior, they have what looks
like a plastic conduit running down into the ground below grade.
You don't do ANYTHING at the power meter -- that's the Power Company's
stuff. You bond to your ENTRY panel -- that is, the first thing on YOUR
side of the meter.
And on the inside, I can pull the panels off and get to the mains feed
ground line. Got to be careful. Or is it enough to connect to the
breaker box casing? The connection between the casing and the "bus
bar" for the ground is not what I would call lightning nuclear duty safe.
The electrical enclosure is required by code to be quite solidly bonded.
If you care to go into the box, you can bond to the ground bus inside
the panel. Just make sure you're really making contact with the panel,
that there's no paint in the way. You could also bond to the wire coming
from the ground rod(s), but the enclosure is better.
Also, don't assume (makes an ass of you and me) that the electrical
contractor did it right. The turkey who wired my home in CA made a
total mess of grounding. Everything you can think of was wrong. Study
the Power and Grounding piece on my website, then do a serious
inspection of it. If you're lucky, you won't have to take your shoes
off to count the problems. I wasn't that lucky.
