Re: The differenece ground wires
One is stranded the other is solid
I believe the NEC requires #6 and larger to be stranded though we do have a coil of #6 solid TW insulated (in telephone gray I might add) ground wire that we use to ground TELCO protectors and equipment.

Re: The differenece ground wires
250.62 allows both with no restriction on size for grounding electrode conductor.
250.118(1) allows both with no size restriction for equipment grounding conductor.
I have never heard of this requirement?

Re: The differenece ground wires
Section 310.3 states, "where installed in raceways, conductors of size 8 AWG and larger shall be stranded."
The Exception then states, "as permitted or required eleswhere in this code".
Grounding conductors would be one of those exceptions.

Yup, that's what I was thinking of. If I had gotten up off my butt and looked in the book I could have quoted it correctly!

Re: The differenece ground wires
"As permitted or required elsewhere in this code" - one example is solid 8 AWG used in raceways for pools, as we us a lot of solid 8 AWG, so they relax the Chapter 3 requirement somewhat.
