How to determine wire gauge for higher DC voltages?

I have Will Prowse's which contains a wire gauge chart for 12v dc, but, what about for voltages in the 80v dc range?
I'm now planing on using 2 higher voltage (~40 Voc) residential panels in series with a ~12' run to the SCC. How do I determine the minimum wire size?
Thx.
 
Pollenface, thanks for sharing. I noticed that it has the option for AC or DC. I have added the link to my favorites.
