The basic 'unwritten rule' that is followed around here for the panel in basement scenario is:
Drill in above sill plate; turn straight down, and enter the panel. This works for even the high ceiling basements.
This seems to work for 'mostly' everyone. Yes, we get the occasional, drill in, turn left for xx' then down into the panel. That don't work!
Commercial jobs, specially the older ones that opted for the good ol' 6 switch rule is where it gets interesting. Bring on the concrete!!
