Where raceways are installed in a location with fluctuating temperatures, what must be managed to prevent condensation?

In an environment with fluctuating temperatures, managing warm air circulation is crucial to prevent condensation within raceways. When warm air meets cooler surfaces or materials, such as the walls of a raceway that may be at a lower temperature, it can lead to condensation of moisture present in the air. This condensation can cause electrical components or wiring to corrode or short-circuit, leading to potential hazards.

By ensuring adequate warm air circulation, the temperature difference between the warm air and the raceway surfaces can be minimized, reducing the likelihood of condensation forming. This helps maintain a stable temperature within the raceway, preventing moisture accumulation and its associated risks.

While other strategies might be useful in managing moisture, ensuring warm air circulation directly addresses the thermal dynamics that lead to condensation.
