What can improper sealing of raceways result in?

Improper sealing of raceways can lead to corrosion and moisture ingress because raceways are designed to protect electrical conductors from environmental elements. When raceways are not sealed correctly, water, humidity, and contaminants can enter the enclosure, creating an environment where corrosion can thrive. Corrosion can damage electrical components, degrade insulation, and ultimately lead to failures in the electrical system. Additionally, moisture ingress can result in short circuits or other electrical malfunctions, posing safety hazards. Thus, ensuring proper sealing of raceways is crucial to maintaining the integrity and safety of the electrical installation.
