I was also wondering what wire gauge and type cable I should use if I want to install a 100 Amp circuit instead of a 50 Amp circuit.
I'll just comment on this part.
You dont want to be pulling #3 (for 100AWG) through conduit.
Jeezus Hard Christ it is!
Also, I don't see #3 fitting in a 50A generator inlet
