Where exposed to the weather, raceways enclosing service-entrance conductors shall be suitable for use in wet locations and must be what?

When raceways enclosing service-entrance conductors are exposed to the weather, it is critical that they are arranged to drain. This ensures that any water that enters the raceway can escape, thus preventing the accumulation of moisture that could lead to corrosion, electrical shorts, or other issues that may compromise the integrity and safety of the electrical system. Proper drainage is essential in maintaining the functionality of the raceways in wet locations.

Choosing an arrangement that promotes drainage reflects best practices in electrical installations, particularly in environments where there is a high likelihood of exposure to water or moisture. This helps to guard against potential damage caused by stagnant water and extends the lifespan of the raceways and the conductors within them.
