What is a key feature of EMT?

The key feature of EMT, or Electrical Metallic Tubing, is that it has a circular cross-section and is unthreaded. This design allows for easier installation and handling, as it is lighter than heavier conduits and does not require threading for certain fittings. EMT is also known for its ability to provide a degree of protection to electrical conductors. Its unthreaded nature simplifies connections, as fittings can be quickly attached without the need for threading tools, making it a common choice in many electrical installations.

In terms of its circular design, EMT is manufactured to ensure a uniform cross-section, which helps in the efficient and neat installation of electrical systems. The ease of bending and cutting further enhances its usability in various applications.
