Romex Hanging In Attic

The national electrical code nec outlines specifications for securing nm cable and other electrical wiring.

Romex hanging in attic.

I did a lot of reading about it but am confused about the best way to do it. I m thinking of installing some 3 pipe hangers such as below on the underside of the rafters to help with running 12 2 nm b romex cables for now and in the future. An attic that is accessible which is defined by the nec as having a permanently installed stair or ladder in place must have protection for any cables that run across the top of the attic floor joists or within 7 feet where they run across the face of rafters or studs. Adding a new ceiling light direct wiring an attic fan or installing any other type of overhead electrical fixture requires access to electricity.

Romex can be installed above or under the insulation. Attaching an electric wire under a ceiling joist. Most of the wiring in a modern home consists of runs of nonmetallic sheathed cable or nm cable also known by the popular brand name romex. A pull down attic ladder does not count.

Hi all i have to run some romex in my attic. You can then splice on a new piece of wire make sure it is the same wire gauge and run the new piece from the junction box back to the fixture box. 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. Nm cable must be supported by framing when running through walls ceilings and floors.

It is ok to touch the outer jacket with your bare hands provided the insulation is not damaged.
