What type of facilities does Article 555 cover?

Article 555 of the National Electrical Code (NEC) specifically addresses the electrical installations in marinas and boatyards. This article is critical because it provides specialized requirements to ensure the safety and proper operation of electrical systems installed in these environments, which can be subject to unique hazards such as exposure to water and the presence of boats.

The provisions within Article 555 address various aspects, including the installation of branch circuits, equipment for charging electric vehicles, and requirements for connection to shore power. This is important not only for the safety of the electrical installations but also for the protection of the environment since marinas and boatyards interact with bodies of water.

While other areas, such as temporary installations, office furnishings, and cranes and hoists, have their own dedicated articles in the NEC, they are not covered under Article 555. This makes the focus on marinas and boatyards essential for anyone involved in planning or implementing electrical work in those specific facilities.
