What does 'Smurf tube' reference in the context of electrical installations?

In the context of electrical installations, the term 'Smurf tube' refers to another name for Electrical Nonmetallic Tubing (ENT). This type of conduit is flexible and lightweight, commonly used for running electrical wiring in residential and commercial buildings, particularly where the rigidity of traditional conduits is not required or practical.

The advantage of using ENT or 'Smurf tube' is its ease of installation in tight spaces, as it can bend easily without the need for special fittings, making it an efficient choice for electrical applications. Its blue color also contributes to the nickname 'Smurf tube,' as it resembles the color associated with the Smurfs.

Thus, associating 'Smurf tube' with ENT illustrates a common vernacular in the electrical trade that simplifies communication among professionals regarding the materials they work with.
