when i went to a 100 amp subpanel, guess what i used. HD doesn't even sell copper for that size, at least not in ROMEX, i believe they had THHN
When I ran underground service to my shop 10 years ago, HD around here had 2/3 w/ground ROMEX for like $1.25/ft. They still do according to their website but it's $6/ft now!. But that cannot be used underground and the only thing they carried large enough and 'W' rated was 1/o (or maybe 2/o) aluminum, good for 125A. So that's what I used, with the anti-ox on the connections.
