What is the primary benefit of Class 2 wiring insulation?

Class 2 wiring insulation is primarily designed to enhance safety from fire hazards. This type of wiring is intended for low-voltage applications, typically rated up to 100 volts, and is remarkably limited in power handling to prevent excess heat production. The insulation used in Class 2 cables is engineered to reduce the risk of overheating, which significantly lowers the potential for fire ignition. In addition, the performance characteristics of Class 2 wiring help to minimize the consequences of faults, ensuring that, even if a fault occurs, the risk of flame propagation is very low.

While the other options may have relevance in different contexts, they do not align with the primary design intent of Class 2 wiring insulation, which primarily prioritizes safety. Higher voltage tolerance, thermal resistance, and flexibility are not the main focus of Class 2 wiring; rather, its safety in low-voltage installations is essential for protecting both people and property. Thus, it is correct to identify safety from fire hazards as the primary benefit of Class 2 wiring insulation.
