What is the most commonly used tubing for electrical wiring?

EMT, or Electrical Metallic Tubing, is the most commonly used tubing for electrical wiring due to several key advantages it offers. Firstly, EMT is lightweight and easy to handle, which simplifies installation processes. Its metallic construction provides excellent protection for electrical wires against physical damage and environmental factors, making it suitable for various applications both indoors and outdoors.

Additionally, EMT has a smooth interior surface that allows for easy wire pulling, which can be especially beneficial when working with longer runs of wiring. It is also non-combustible and provides grounding capabilities, as the metal casing can be bonded to the grounding system of the electrical installation. The cost-effectiveness of EMT compared to other types of conduit, combined with its durability and versatility, further solidifies its status as the predominant choice among electrical professionals for wiring projects.
