What is the primary characteristic of Class 2 conductors?

Class 2 conductors are specifically utilized in low-voltage communication systems, which is why this choice is the correct answer. These conductors are defined by their ability to safely operate at low voltage levels, typically not exceeding 60 volts DC or 30 volts AC, and are designed to provide power for low-energy devices and signal transmission without posing significant hazards. This makes them ideal for everyday communication systems, such as data and control systems, alarm systems, and audio/video distribution networks.

The low voltage characteristic of Class 2 conductors ensures that they can be used in residential and commercial applications while minimizing the risk of electrical shock or fire. This provides a crucial advantage in installations where safety and power limitations are essential.

In contrast, the other options revolve around characteristics not applicable to Class 2 conductors. For instance, they are not primarily designed for power distribution like higher voltage systems; they do not handle higher voltage applications; and while they can carry current, the current levels are not regarded as significant compared to those managed by higher class conductors. This further solidifies the uniqueness of Class 2 conductors in the context of low-voltage communication.
