Anyone know the requirements (NEC chapter 3, I think) for when/where you must use conduit? Supplying a garage sub panel through basement (approx 65') and up into a 2 x 4 drywall cavity in the garage. (if it matters it's 2/3 NMB copper)
Inside the wall conduit wouldn't be required if you use the properly sheathed cable.
So where would you be putting conduit? In the chase is your plan just to pull it through without stapling it? Not sure that is a problem, but you will want to make sure the cable won't be subject to damage from someone driving a screw or nail into the ceiling or wall and hitting the cable.
Ampacity for #2 copper is 95A @ 60C, right?
I used XHHW-2/2/2/4 for my 100 amp sub panel.using xhhw-2 ser, should be good to 105A
