I want to run a number of new circuits onto a single long wall. There will be 6 or 7 circuits total on a wall that's about 50'. They will all use 12/2 from 20A breakers and feed new 20A receptacles.
Right now I only know of one good path from the basement to the 2nd floor. However, from what I've read it seems I can't just run all these cables in one big bundle. How much separation do I need between them? How many can I bundle without heat being an issue?
Once into the attic (thankfully I have some low attic access to the back of this long wall) I can come up a roof joist and then down a stud on the back of this wall and then fan out in the appropriate direction. 6 of the 7 will head in one direction though. So as I run through the studs, I don't want to drill 6 holes in each one. How many can I bundle here? What's the separation requirement?
thanks!
