What requirement applies to multiconductor cable exposed to direct sunlight according to OSHA?

Multiconductor cable exposed to direct sunlight must be identified as sunlight resistant to ensure its integrity and performance in environments where it is subject to prolonged exposure to ultraviolet (UV) radiation. This requirement is in place because direct sunlight can degrade the insulation and outer jacket of cables over time, which can lead to electrical failures or safety hazards.

The identification as sunlight resistant signifies that the cable has been tested and specified for use in such conditions, ensuring it meets the necessary standards for durability and safety. This helps to prevent potential risks associated with damaged cables, such as electrical shorts or fire hazards, ensuring reliable operation of communication systems that utilize these cables.

This requirement underscores the importance of using materials that can withstand environmental conditions, which is critical for maintaining the safety and functionality of low voltage communication systems.
