Which article governs Mobile Home Parks and related structures?

The National Electrical Code (NEC) Article 550 specifically governs Mobile Home Parks and related structures. This article provides requirements for the installation of electrical systems in mobile home parks, including service equipment, feeders, branch circuits, and the installation of outlets.

Article 550 is tailored to address the unique aspects and safety considerations involved in mobile home parks, such as spacing between homes, service connections, and grounding requirements. It acknowledges that mobile homes may have distinct needs compared to traditional residential structures as they often involve temporary installations or mobile wiring methods.

In contrast, the other articles address different contexts: Article 520 deals with theatrical and show lighting, Article 518 pertains to educational facilities like schools and universities, and Article 545 focuses on modular buildings and structures—none of which specifically address the requirements for mobile home parks and their electrical systems.
