Which of the following is true about the threading of conduits into a T-type conduit body?

Using threaded connections for conduits into a T-type conduit body ensures a secure and stable installation. Tightening the threads creates a strong mechanical connection that can resist pull-out forces and maintain the integrity of the conduit system, minimizing the risk of accidental disconnections. This is particularly important in applications where conduits may experience movement or stress, ensuring that the electrical conductors remain protected.

In contrast, options that suggest alternative practices do not address the critical nature of the connection. Stating that threading does not enhance stability undermines the fundamental principles of electrical installation safety. Furthermore, the assertion that threading is not applicable for large conduits overlooks the fact that threading is indeed a standard practice across various conduit sizes, as long as the conduit and fittings are compatible. Lastly, suggesting that only flexible conduits can be threaded misrepresents the types of conduits that utilize thread connections, as both rigid and flexible types can benefit from secure threading techniques.
