Per the NEC as well as NEMA, single conductor insulated #8awg solid copper is the largest allowed building wire. Good luck finding any one that carries it. You may find some old #8 solid copper insulated TW or THW single conductor wire. I can tell you from experience it a bear to work with.
I should have checked before I posted. The old memory ain’t what it used to be.
The NEC for many years has stated conductors pulled in raceways #8 and large shall be stranded. (Key words, in raceways)
I had to go all the way back to the 1971 NEC to find where it said # 6 and larger shall be stranded when installed in a raceway. In the 1971 code it says in 1973 the requirement will change to # 8 and larger shall be stranded when installed in a raceway.
. I did a quick search and didn’t find anything in the 2017 NEC requiring #8 and larger NM sheathed cable (Romex) shall be stranded wire. I’ll spend some time tomorrow and see If I can find anything to the contrary.
There is a Lowes in my area and they show they have 6-2 with ground Romex in stock. I’ll stop by and see if the conductors are stranded or solid.
