I preinstalled some 3/4" blue smurf tube from panel to attic, about a 6ft run. At some point I'm going to try to run 6ga hot tub wire in there. I'm a little confused about conduit fill ratio and what is permissible. I read something somwhere that led me to believe the fill ratio only matters if the conduit is used in an and-to-end (i.e. box to box) manner and doesn't matter for short risers like this that are only terminated on one end. However, I'm skeptical of this as I don't recall seeing an official source.
I suppose if it's an issue, then I could always terminate the smurf tube in the attic to a box, run THHN in the smurf tube, and splice to romex in the box in the attic.
