I have a subpanel in the corner of the basement of my house. If I
drill through the subfloor above the panel immediately at the corner
then the hole ends up going through the bottom plate of a first floor
wall. This is a perfect location since I can then feed wires from the
subpanel to a stud cavity in the the first floor.

Between the panel and the hole in the subfloor I need to attach wires
that go to the first floor. Does code allow me to staple them to the
inside of a rim joist? This would be perfect because the rim joist is
right next to the hole. What about stapling wires to the tops and
sides of sill plates?

Ideally my wires would go as follows: panel to top of sill plate to
rim joist then through the hole in the subfloor. Once I get upstairs I
am fine. But, I want to make sure that my wiring immediately after the
subpanel is up to code.

Thanks.
