Which of the following describes Class 3 conductors?

Class 3 conductors are specifically designed for communication and signaling applications. These conductors are defined by their use in low-voltage scenarios, where they carry signals rather than power, distinguishing them from higher class conductors, such as Class 1 and Class 2. Class 3 conductors typically operate at a maximum voltage of 100 volts and are essential in systems like security alarms, fire alarms, and telecommunications, where reliable signal transmission is critical.

By focusing on communication and signaling functionalities, Class 3 conductors ensure safe and effective operation in various low-voltage environments, helping to facilitate effective communications within systems without delivering power, thereby reducing risks associated with higher voltage circuits. This unique characteristic underlies the correct answer and highlights their importance within low voltage communication systems.
