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. Is the wire supposed to be in conduit through the wall and attic to the breaker. 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. 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.

Define feed wire. The attic wiring should be protected and secured to ceiling joists or other wood structural supports. The most common wires are thhn wires which are individual copper conducting wires with a color coded heat resistant plastic insulation around them. 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.

Whatever size conduit you use don t fill it more than 40 percent with wires. Imc conduit is a thicker conduit that is galvanized making it a great choice for outdoor installations. This will protect the wiring from being accidentally snagged. This is especially true when you need to curve the wires around a bend which further limits the space inside the conduit.

Spacing is a major factor in deciding whether to use conduit. Water heaters can lights and attic vents are great examples of typical flexible conduit installation. The national electrical code has specific regulations for how many conductor wires can fit into within a conduit of each diameter size. Single gang electrical boxes will work but if you have two or more conduit sections connecting to one box buy double gang.

Emt conduit is lightweight easy to bend and is used within the walls. Conduit doesn t cost that much more and it s a lot easier to pull wire through. Electrical conduit is designed for use with specific types of individual conductor wires.
