Which NEC Article focuses on the installation requirements for marinas?

The installation requirements for marinas are addressed in Article 555 of the National Electrical Code (NEC). This article specifically outlines the rules and regulations for the electrical installations used in marine environments, focusing on the unique challenges and safety considerations that arise in such locations. Marinas often have electrical equipment exposed to water and moisture, which necessitates specific protection measures against corrosion and electrical hazards.

Article 555 covers various aspects, including the installation of equipment, service connections, and the protection of electrical systems in marinas, ensuring they are safe and compliant with the NEC standards. By establishing clear guidelines, this article helps to mitigate risks associated with water exposure and enhances overall safety in marina electrical systems.

In contrast, the other articles mentioned serve different purposes: Article 590 pertains to temporary installations, Article 551 focuses on mobile homes, and Article 604 addresses power sources for electric vehicles. These do not specifically target the unique requirements related to marinas.
