    Default Attic wiring

    I have a question, the attic in my house has all the wiring exposed, it is basically sitting on the rafters. Can I just cover it with wood so I can use the attic to walk on?

    Thanks

    No, wiring needs to be protected from chances of nails being driven into it.

    You mean the wires are just sitting on the JOISTS. By code they have to be fastened to the joists.

    For easy walking/crawling I use pieces of plywood, but never nail/screw them to the joists.

    Two questions:

    1. How old is your house?

    2. What is the wiring like? Does it appear to have a fabric or plastic jacket? How thick/wide is the wire? Is it mounted on insulators?

I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.

    I am piggying back with my own questions:

    (1) My 1964 wiring is AC, but new work done used NM wiring in the attic. Is this OK ?
    I intend to add recess lighting and it would a b*t*h if I had to use AC as I never worked with it or have tools (my day job is sitting behind a desk).
    (2) The NM wiring is mainly loose and not secured to the joists. Also, the workmen separated the (new work) recessed light fixtures from the 1964 insulation, and I can see the fixtures are not tight with the ceiling (I can see the room under the attic).
    I believe fixtures are rated for contact or non-contact w/ insulation, and assume the fixtures are non-contact. Now, the attic floor/kitchen ceiling seems opened to the attic via these fixtures. Should I do anything about this (winter air leaks)??

    Thanks.

    It all depends on local code. I am guessing that AC is not required if the updates was done by a licensed electrician.
    (2) The NM wiring is mainly loose and not secured to the joists. Also, the workmen separated the (new work) recessed light fixtures from the 1964 insulation, and I can see the fixtures are not tight with the ceiling (I can see the room under the attic).
    This statement suggests that the work was not done by a licensed electrician, I would suggest you get an inspection you may need a lot of work done.

    Yes, this is not a proper installation and yes there is contact and non contact type units.
    Thanks.
    Again I would suggest an inspection by a qualified electrician.
