There is an attached pull down ladder leading to the attic
I have read about how to run wire by code, but I'm a bit confused if its saying 7' from attic entrance on floor or 7' high. My initial plan was to drill holes in the middle part of the joist just a little bigger than the 12/2 Romex I'm running and I would do it through each joist until I have to run the wire parallel to the joist then run the wire to the electrical box. The insulation will cover the wires so they would never be seen.
The total distance is about 65 feet.
I drew a diagram in paint that might give you a better idea of what I'm saying so you can point out any possible problems.
*The black lines are the joists on the attic floor.
*The brown are the joist that go from the floor all the way up to the roof.
*The red line is where I want to run the line, drilling holes through the joist
*The purple is the other option, running the wire up the side drilling holes through the joist
Once I get the wire ran to where it is parallel to the joist what do I do with the wire? Just let it sit next to the joist?
