Running electrical wire through attic.

Make sure you use ul rated in wall wiring that meets local building and fire codes including cm cmr or cmp for computer networking and cl2 or cl3 for speakers. Running electrical cable inside finished walls starts with marking the framing and planning the best cable route. My attic is non accessible so i know for a fact that i must protect the romex with guard strips or bore holes 1 25 from the face of the joists when running perpendicular to the joists and when i run parallel i must staple the romex to the face of the joists. These holes will be used to fish the cable down into the basement or crawlspace area or up into the attic in order to run the cable from box to box.

I did a lot of reading about it but am confused about the best way to do it. Turn off the power. If you will need to fish wiring through a wall drill a hole through the wood plate in the attic only. Always turn off the breakers in your electrical box before you begin to reduce the chance of an electrical shock should you accidently cut or drill into existing wiring.

Warning if the attic is your only access space for running cable you may find it necessary to cut another small hole in the wall surface high on the wall in order to gain access for drilling through the wall s top plate. Watch the entire process step by step. The attic wiring should be protected and secured to ceiling joists or other wood structural supports. When cutting through drywall from the interior of a room use a utility knife and cut carefully you don t want to drill through a hidden wire or the paper backing of the attic insulation.

Running wires inside rigid conduit. Hi all i have to run some romex in my attic. The problem is that my panel is on the exterior wall and the conduit will need to enter the attic space. Select proper wire or cable.

Whenever i do attic wiring i remove the insulation and staple it to the ceiling joist. And use semi rigid wiring fish tape to pull your wiring down to your outlet location. Yes this should be corrected and it would be good to have the wiring and all the circuit connections inspected as well. To run the wires inside rigid conduit you ll need a hacksaw a pipe bender capable of bending 1 2 in.

If this meets code then i will be running attic wiring in this manner from now on. Rigid conduit with an outside diameter of 3 4 in and a fish tape long enough to reach through the buried pipe.
