In Article 110.10, what is specified about the physical condition of conductors?

The specification in Article 110.10 regarding the physical condition of conductors emphasizes the necessity for conductors to be protected from physical damage. This is critical because conductors that are not properly protected can be susceptible to wear and tear, environmental factors, and mechanical impacts which may compromise their operation and safety. Ensuring that conductors are safeguarded against such potential hazards helps to maintain their integrity, supports the functionality of the electrical system, and minimizes risks associated with electrical failures or accidents.

In contrast, options concerning insulation from surfaces or color-coding for identification address other aspects of installation safety and regulatory compliance, while handling high voltage relates more to electrical ratings and capacities rather than physical protection. Therefore, the focus of Article 110.10 highlights the importance of physical protection to ensure longevity and safety in the electrical system.
