Do i need to use conduit in the attic.

When romex is run across rafters in an open unfinished attic it is my position that a raceway of some kind 1x3 s or even 2x4 s should first be attached across the affected rafters perhaps 3 to 4 above the joists then the wiring be stapled to the raceway. The attic wiring should be protected and secured to ceiling joists or other wood structural supports. I cannot find this specifically in code so here is my question. This is especially true when you need to curve the wires around a bend which further limits the space inside the conduit.

I plan on finishing the basement this year and want to ensure i run the correct wires ahead of time should i wish to install an antenna or security system in the attic at some point. It also is easily damaged unlike imc or rigid conduit. Define feed wire. Emt conduit is lightweight easy to bend and is used within the walls.

Electrical conduit is designed for use with specific types of individual conductor wires. Whatever size conduit you use don t fill it more than 40 percent with wires. Methods of proper attic electrical wiring raul no this is not a standard practice and is most likely the result of improper installation of electrical attic wiring. Spacing is a major factor in deciding whether to use conduit.

The most common wires are thhn wires which are individual copper conducting wires with a color coded heat resistant plastic insulation around them. A gray colored cable with wires inside a sheath or is it three or four individual conductors run from the meter to the panel. This will protect the wiring from being accidentally snagged. The volume of regulators inside the conduit is limited by code so it might not work to use conduit.

Imc conduit is a thicker conduit that is galvanized making it a great choice for outdoor installations. The national electrical code has specific regulations for how many conductor wires can fit into within a conduit of each diameter size. Hi i had the builder install a conduit from the attic to the basement when i purchased the home.
