Conduit From Attic To Closest

I am concerned with the integrity of the wire and want to run a new wire from my attic which is closest to the fixture to my breaker box in the basement.

Conduit from attic to closest.

From the nearest edge of the framing member or furring strips where nails or screws are likely to penetrate. You would transition from your nms in the junction box to thwn which is pulled into the panel. So just use like 1 conduit and a large junction box in the attic and or basement. That being said conduit would be your safest choice.

And running conduit up the outside. Of course removing the floor area in the general area will solve the issue but the drill bit will locate exactly where the access will be needed. The nm b cable doesn t have to be in conduit unless it s exposed to potential damage. Once located you need only remove the floor where needed to get to and from the wall space.

2 romex into the attic the romex probable needs to be clamped so hopefully i can position the solardeck in a way that a short run of plastic conduit lands near a diagonal roof member to mount a junction box which will only be used for the clamp no actual electrical junction. If you are just assuring future access to the breaker panel from the attic to install more branch circuits simply run a 2 conduit from the ceiling straight down into the panel and leave it empty for now. Conduit from basement to attic allows wiring run to the second floor interior walls and ceilings. If you have an unfinished basement running cabling to the main floor walls is not difficult for those skilled to do such.

And leave a pull string for the next ones. Next would be drilling holes through the joist and threading the. The bit will penetrate the attic floor from below if steady even pressure is used on the drill. What is the code for electrical wiring in an attic going over the joists and be stapled or drilled through.
