I plan to install a surface mounted panel box on a residential garage interior masonry wall . There are dwelling rooms above the ceiling so the ceiling in the garage must have 5/8" type x drywall . My question is can I use sch 40 rigid PVC to provide a sleeve up to through the ceiling to bundle the NM cables ? Also how do you figure the 40 % fill for the NM cables ? Do you just measure them and estimate the cross section areas ? I don't see any tables for conduit fill for cables with 3 conductors . Will I have to use Rigid Metallic or EMT because of the fire rating ?
