What is true regarding low-voltage and special wiring systems?

Low-voltage and special wiring systems are particularly sensitive to contamination and corrosion, making it essential to maintain these systems in a clean and dry environment. Contaminants such as dust, moisture, and chemicals can degrade the materials used in low-voltage wiring, leading to failures in the system. This sensitivity means that any exposure to corrosive substances can negatively impact the integrity of the wiring, resulting in potential safety hazards or operational issues.

Understanding this sensitivity is crucial for professionals working with these systems, as it highlights the importance of regular inspections and maintenance to ensure their longevity and proper functioning. The other choices provided do not accurately reflect the characteristics of low-voltage and special wiring systems, as they typically do not require high currents, are not designed for heavy industrial applications, and while they can exhibit durability, they are not resistant to all conditions, especially environmental factors that can lead to corrosion and contamination.
