What type of conduit is used predominantly in residential applications?

In residential applications, Electrical Metallic Tubing (EMT) is predominantly used because it provides a combination of durability, protection, and ease of installation. EMT is a lightweight, thin-walled metal conduit that is easy to handle and install, which makes it ideal for residential settings where labor efficiency is a consideration. It not only protects electrical wiring from physical damage but also offers excellent grounding capabilities, which is crucial for safety in residential wiring.

EMT is often chosen for indoor use in residential applications because it can be easily bent and cut, allowing for flexibility in accommodating various installation scenarios. Additionally, its metal construction can withstand environmental factors that might otherwise damage softer materials. This makes EMT a preferred choice over options like Flexible Metallic Tubing, which is more suitable for areas requiring flexibility, and other types of nonmetallic conduits that might not provide the same level of durability and grounding efficiency.
