Which material is NOT typically used for electrical conduits?

Wood is not typically used for electrical conduits because it does not provide the necessary protection and safety that electrical wiring requires. Conduits serve to safeguard electrical wires from physical damage and environmental factors, as well as to maintain a safe electrical system. Materials like PVC, steel, and aluminum are chosen for conduits because they are non-combustible, resistant to corrosion, and capable of providing a durable and protective enclosure for electrical conductors.

PVC (Polyvinyl Chloride) is lightweight, resistant to moisture, and is commonly used in underground work and areas where corrosion is a concern. Steel is strong and can withstand higher physical impacts, making it suitable for industrial environments where durability is critical. Aluminum conduits are lightweight and resistant to corrosion, making them ideal for applications where weight is a factor, such as in overhead installations.

In contrast, wood does not offer the necessary durability or fire resistance and can deteriorate when exposed to moisture, making it an unsuitable choice for electrical conduit applications.
