In the context of raceways, what are conductors?

Conductors are materials or wires that transmit electrical current, which is why this choice is the correct answer. In electrical systems, conductors are typically made of metals, such as copper or aluminum, because these materials have a high degree of electrical conductivity. This allows them to effectively carry electric current from one point to another in a circuit, making them essential in any wiring system, including those utilizing raceways.

The other options do not accurately describe the role of conductors in electrical systems. Insulating materials, mentioned in the first choice, refer to substances that prevent the flow of electric current, which is the opposite of what conductors do. The third choice, focusing on outer coverings, only addresses a part of the entire conductor structure and does not encompass the essential function of current transmission. The fourth choice about tools used for installing raceways is unrelated to the definition of conductors themselves. Understanding conductors is fundamental to grasping how electrical systems operate within raceways and raceway fittings.
