Why are conduit seals important in electrical installations?

Conduit seals play a crucial role in electrical installations primarily by preventing moisture and contaminants from entering the conduit system. This is vital because moisture can lead to corrosion of electrical conductors and connectors, which can cause failures or hazardous conditions such as short circuits. Contaminants, such as dust or dirt, can also interfere with the electrical connections and diminish the system's overall performance and safety. By properly sealing conduits, installations can maintain optimal function, longevity, and safety, reducing the risk of electrical hazards that could arise from exposure to outside elements.
