I'm adding a 100 Amp main lug panel right next to my other panel (200 Amp service). Single family dwelling and my county uses NEC 2008 code. Just wondering the easiest wire to use to feed the panel (in an unfinished basement). Do you recommend sheathed SE/SER copper or THHN in conduit? Can I use #1 or #2 NM or does it have to be SE/SER? I'm just wondering what gauge and type of wire to use (don't want to take any chances with the inspector so I'd rather be conservative).
