Lifespan of Different Wiring Materials

Historically, materials like rubber and cloth were used in home wiring. In modern times, the general choice is PVC coated copper. PVC-coated copper wire is generally considered to have a longer lifespan compared to older materials. Environmental conditions and usage patterns can influence the longevity of your wiring. 

Factors Affecting Lifespan

Environmental factors such as humidity, temperature fluctuations, and exposure to moisture can accelerate wiring degradation. Heavy electrical usage and overloading circuits can also contribute to wear and tear on wiring materials. Homes with older electrical systems or outdated wiring may be more susceptible to wiring issues.
