Why should installers avoid running cables in areas with excessive humidity?

Installers should avoid running cables in areas with excessive humidity primarily because of the potential for corrosion, which significantly diminishes the lifespan and reliability of the cables. Humidity introduces moisture that can infiltrate cable jackets and insulation, leading to the oxidation of metal components within the cables. This corrosion can result in electrical failures, signal losses, and ultimately, the need for premature replacements.

In addition to corrosion, high humidity can create an environment conducive to mold and mildew, further compromising the integrity and performance of the cabling system. Ensuring that cables are installed in dry areas protects them from these damaging effects and helps maintain their functionality over time.
