Name one common type of conduit used in electrical installations.

CPVC (Chlorinated Polyvinyl Chloride)
PVC (Polyvinyl Chloride)
EMT (Electrical Metallic Tubing)
IRV (Insulated Rigid Vinyl)

The correct answer is: EMT (Electrical Metallic Tubing)

Electrical Metallic Tubing (EMT) is a widely used conduit in electrical installations due to its lightweight, durable, and non-corrosive properties. EMT is typically made of galvanized steel, providing excellent physical protection for electrical cables and conductors. It is designed to be easy to install and can be bent using various handtools, simplifying the process of navigating around obstacles in a building's structure. EMT offers a smooth interior surface that helps reduce the likelihood of damage to wire insulation during installation and ensures a more efficient routing of wires. It is also often used in exposed locations where a neat, professional appearance is desired. EMT can be grounded easily, which adds an additional safety feature in electrical installations. Overall, EMT is favored in many commercial and industrial applications, making it one of the most common conduit types used by electricians.
