What does NEC Article 300.2 address?

NEC Article 300.2 focuses on the separation of conductors based on their usage and voltage levels, which is crucial for ensuring safety and reducing electromagnetic interference among different systems. It establishes requirements that dictate how conductors carrying different voltages should be separated to prevent insulation failure and potential hazards.

For example, it specifies that conductors operating at different voltage levels, such as high voltage and low voltage, need to be physically separated to prevent any fault current from transferring between them, which could lead to short circuits or other dangerous situations. This article is important for maintaining the integrity of both the conductors and the systems they serve.

The other options do not accurately capture the main focus of Article 300.2. The requirements for wire insulation types relate to material specifications laid out in other sections. Standards for cable tracing and identification involve proper labeling and documentation, while guidelines on conductor sizing and ratings pertain to selecting appropriate sizes based on load calculations, which are addressed in different articles of the NEC.
