Temperature variation can significantly influence the performance and safety of electrical sleeves or raceways. When installations are subjected to varying temperatures, particularly in environments that experience significant shifts between hot and cold, condensation can form inside the raceways. This moisture accumulation poses a risk for corrosion, short circuiting, or even potential electrical failures.

Additionally, if the installed conductors are not rated for the temperature conditions present, it can lead to insulation breakdown or a decrease in the overall lifespan of the electrical components. Therefore, the concern of condensation due to temperature fluctuations highlights the importance of considering the environment in which electrical systems are installed. Proper planning and material selection are crucial to mitigate these moisture-related issues, ensuring safety and reliability in electrical installations.
