Hi-
Long time lurker, first time poster.
I'm trying to run a feeder for a 100 amp subpanel from main panel in my basement to my attached garage (house built in a hill, so on the same level).
I've had two electricians out to take a look, and 3 potential approaches to doing this have come up:
1) Run a cable down a wall ~30 feet, enter the garage, and then run on the surface to subpanel in the garage ~15 feet (I'll be using conduit to run branches within the garage, so don't mind this cable on the surface; garage is cinderblock on 3 of 4 walls).
2) Run a cable down another wall (main panel in a corner) about 15 feet, then enter an I-beam soffit and run ~25 feet down that soffit, enter the garage, and then run ~20-25 feet to the subpanel.
3) Run through the ceiling ~35-40 feet to the subpanel.
Of these options, I favor 1 or 2. I'm going to repaint the basement walls anyway so I don't mind cutting a section out to run cable, but really don't want to mess with the textured ceiling.
Regardless of which one of those options I end up doing, or whether I do the work or hire an electrician (I'm getting estimates that look like 400-500 in labor, which I find a little more than I want to pay), the challenge is the wall. From what I can tell, the structure of the basement is cinder block with a 2x4 wall put on top to hold the drywall, except the 2x4's are turned sideways, so the actual amount of open space is ~1.5". Feeder cable for ~100 amp subpanel looks to be about 3/4" or bigger.
Any idea on the best way to approach this? About the best solution I have is to drill a 1" hole as centered as I can in each of the studs, and put metal protective plates on the front. I think this works from an NEC perspective (using metal covers where wire runs <1.5" from front of stud), and should be fine from a building code perspective since these walls aren't load bearing.
Any suggestions or thoughts would be helpful.
Thanks!
