Which NEC article governs the design of circuits supplying power to boats?

NEC Article 555 specifically addresses the requirements for electrical systems and installations on boats and marinas. This article is crucial because it outlines the safety measures and considerations critical when designing circuits to supply power to boats. It includes regulations on grounding, wiring methods, and the types of equipment that can be used, taking into account the unique environmental concerns associated with watercraft.

This article ensures that electrical systems are designed to safely manage the specific challenges posed by the marine environment, such as exposure to moisture and corrosion, which can significantly affect electrical components. By adhering to the guidelines provided in Article 555, professionals can ensure both the safety of the electrical installations and the protection of the vessels and their occupants.

Other articles mentioned do not specifically pertain to marine applications; Article 750 deals with emergency systems, Article 400 concerns flexible cords and cables, and Article 300 addresses general wiring methods. Thus, they are not relevant to the design of circuits for boats.
