Do i need to use conduit in the attic.

Hi i had the builder install a conduit from the attic to the basement when i purchased the home. The most common wires are thhn wires which are individual copper conducting wires with a color coded heat resistant plastic insulation around them. Whatever size conduit you use don t fill it more than 40 percent with wires. Electrical conduit is designed for use with specific types of individual conductor 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. 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. Emt conduit is lightweight easy to bend and is used within the walls. The volume of regulators inside the conduit is limited by code so it might not work to use conduit.

Single gang electrical boxes will work but if you have two or more conduit sections connecting to one box buy double gang. Imc conduit is a thicker conduit that is galvanized making it a great choice for outdoor installations. The attic wiring should be protected and secured to ceiling joists or other wood structural supports. This will protect the wiring from being accidentally snagged.

The national electrical code has specific regulations for how many conductor wires can fit into within a conduit of each diameter size. Water heaters can lights and attic vents are great examples of typical flexible conduit installation. 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. A gray colored cable with wires inside a sheath or is it three or four individual conductors run from the meter to the panel.

Define feed wire. I cannot find this specifically in code so here is my question. It also is easily damaged unlike imc or rigid conduit.
