A pole that is over how many years old should be supported to ensure stability?

The age of a pole is a significant factor in its stability and structural integrity. Generally, poles have a lifespan that can be affected by various factors including material, environmental conditions, and maintenance practices. Typically, a pole that is over 20 years old may begin to show signs of deterioration. Supporting older poles is crucial to prevent potential collapse or failure, especially in areas where they carry significant loads or are exposed to harsh weather conditions.

Poles that exceed 20 years of age are more susceptible to issues such as rot, rust, and structural weakness. Implementing support measures ensures that these poles can continue to function safely and effectively. While poles may be usable beyond 20 years with proper maintenance, the need for additional support often becomes a matter of safety assurance at that age. Thus, focusing on the 20-year threshold provides a reasonable guideline to maintain safety and reliability in electrical infrastructure.
