What type of facilities does Article 555 cover?

Article 555 of the National Electrical Code specifically addresses the electrical requirements for marinas and boatyards. This article is crucial because facilities that deal with watercraft have unique safety considerations due to the presence of water, which can create hazardous conditions if electrical equipment is not properly installed and maintained.

The purpose of this article is to establish safe standards that ensure the integrity of electrical installations in these areas, which often involve fueling, maintenance, and storage for boats and marine applications. Article 555 ensures that these installations meet safety regulations to prevent electrical shock hazards and other risks related to working near water.

Other options, such as temporary installations, office furnishings, and cranes and hoists, fall under different articles within the NEC that address their specific requirements and safety measures. Therefore, understanding that Article 555 focuses solely on marinas and boatyards helps clarify the specialized nature of electrical installations in environments exposed to water and the associated risks.
