What is required of auxiliary gutters according to NEC?

The requirement for auxiliary gutters according to the National Electrical Code is to ensure they are sealed securely. This is essential for several reasons. A well-sealed auxiliary gutter prevents moisture and contaminants from entering the electrical system, which could lead to corrosion and electrical failures. Proper sealing also minimizes the risk of electrical short circuits that can occur due to water ingress.

By sealing the gutters, it ensures that the overall integrity of the system is maintained, enhancing both safety and reliability. Proper sealing contributes to the effective functioning of the gutter system in managing electrical conductors and protecting them from adverse environmental conditions. In summary, secure sealing of auxiliary gutters aligns with NEC requirements to uphold safety standards in electrical installations.
