Which regulatory body sets standards for AC and DC electrical systems on boats?

The American Boat and Yacht Council (ABYC) is the primary organization responsible for establishing standards specifically related to electrical systems on boats, which includes both AC (alternating current) and DC (direct current) electrical systems. ABYC standards are developed to ensure the safety and reliability of marine electrical installations, addressing issues such as wiring methods, circuit protection, grounding, and proper component selection.

ABYC standards are widely adopted in the recreational boating industry and are frequently referenced in boat manufacturing and repair practices. They emphasize safe practices and compliance with regulations which are essential for the protection of both the boating industry and its users. Other organizations like ISO (International Organization for Standardization), IEEE (Institute of Electrical and Electronics Engineers), and NFPA (National Fire Protection Association) have their own sets of standards related to electrical systems, but they do not specifically focus on the unique environmental and operational conditions found in marine settings as ABYC does.
