Question: 1 / 445

Which type of conduit is typically installed underground?

Electrical Metallic Tubing (EMT)

Rigid Metal Conduit (RMC)

Intermediate Metal Conduit (IMC)

Schedule 80 PVC

The selection of Schedule 80 PVC as the type of conduit typically installed underground is accurate due to its specific design and properties that make it suitable for such applications. Schedule 80 PVC is thicker and more durable than Schedule 40 PVC, providing enhanced resistance to impact and crush forces, which is essential for protecting electrical wires or other lines buried underground. Moreover, PVC does not corrode, making it ideal for underground installation where moisture or soil acidity may be a concern.

In addition, Schedule 80 PVC is lighter and easier to handle compared to metal conduits, which can be an advantage during installation. Its flexibility also allows for easier routing around obstacles. Overall, the combination of durability, weather resistance, and ease of use positions Schedule 80 PVC as the favored option when conduits must be installed underground.
