What should support cables in a low voltage configuration?

Support cables in a low voltage configuration should indeed support the building structure. This is important because the building structure provides a stable and secure platform for mounting the cabling systems, ensuring that they are installed properly and remain functional over time. When cables are supported by the building structure, they can be anchored at appropriate intervals, reducing strain on the cables and preventing potential damage due to movement or environmental factors. This is crucial for maintaining the integrity and performance of low voltage communication systems.

The ground surface, metal poles, and wooden beams are not optimal choices for supporting cables in this specific context. While they might provide some level of support, they do not offer the same reliability and structural integrity as the building itself. Therefore, utilizing the building structure is the most effective and standard practice in low voltage installations to ensure safety and compliance with building codes.
