Any change to grounding AWG in 2020 NEC?

Particularly in reference to using #8 AWG for the ground for a 100 amp service. Appreciate the time guys.

You (possibly) can per 250.66 but it would need to be installed in a raceway.

Agreed on the raceway.

What do you mean by ground, see article 100 definition of ground.

#8 has to be in a raceway, #6 may need a raceway so I usually just run #4 unless I know I can run #6 without protection. I have herd of inspectors not accepting #6 if run through drilled joist holes supported every 16" through the joists. So I am paranoid

Earth ground for a sub panel.

I bought a 500 ft spool of 6AWG due to the number of docks/marinas in my area, and the AHJ requires minimum #6. Waste of money and space on the truck to have 2 spools of wire so close in size.

If using PVC for protection in 2020 you need SCH 80 per 250.64(B)(2)&(3)

2020 NEC is available on line at NFPA.org

So you mean the GEC (grounding electrode conductor)? Also your first post mentioned a service now it's a sub-panel? Remote structure?
