100 amp Sub-Panel Installation
Using #2 copper would avoid any problem with your inspector. If you use #2-3 with ground non-metallic sheathed cable, the ampacity is 95 amps, but there is a rule (240.4(B)(3))that allows you to round this up to 100 amps which is a standard size overcurrent device.
What do you mean by encased?
