Thread: Installing Romex in unfinished attic question

    Default Installing Romex in unfinished attic question

    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?

    If you are drilling holes there is no problem. The code you are referring to is if the cable is stapled to the top of the joist and the attic not a walkup. It's to keep people from piling stuff on top of the cable and damaging it.

    Well in that case since I'm running the wire through the joist does that mean I can run the wire at any distance from the attic entrance? -ie: 2ft, 5ft, 7ft?

    Yes because anything you stack in the attic will be on the joists and not on the wire causing damage. Just keep the holes at least 1.25 from edge of joist.
