What term is used for electrical conduits that are suitable for use underground or embedded in concrete?

The term that refers to electrical conduits suitable for use underground or embedded in concrete is commonly known as raceways. Raceways are designed to provide a protected environment for electrical wiring, ensuring safety and durability in various installations, particularly those exposed to harsh conditions like moisture or physical impact.

In the context of electrical installations, raceways can encompass several types of conduit, such as rigid metal conduit (RMC), intermediate metal conduit (IMC), and non-metallic conduits like PVC. These conduits not only protect the wiring but also facilitate organization and installation ease.

While electrical ducts are sometimes used in specific contexts, they do not generally refer to the broader category of conduits and raceways suitable for underground use. Condulets and junction boxes are components used to connect different lengths of conduit or to create a point for wire connections, but they do not describe the conduit types designed for burial or embedding. Understanding the correct terms helps in selecting the appropriate materials for safe and compliant electrical installations.
