MY QUESTION.. what difference does it make? Meter or first ocpd?

The ground is the most unlikely of all conductors to get abused. Once installed it is virtually untouched for it's entire life.

I have yet to get a call or be sent on a call to fix or replace a damaged or a loose ground wire. I am not saying it can't happen. But a Jumbo jet could slam into it too.

This is probably the toughest conductor of them all. As a matter of fact if I am correct a #4 or larger doesnt even require protection or support.

A solid conductor is hard to secure but if done right I see no need to require access. I cant access a buried acorn unless I dig it up...thats not accessible.
