What must galvanic isolators comply with when installed on boats?

Galvanic isolators are devices designed to prevent galvanic corrosion by breaking the electrical connection between a boat's electrical system and the shore power system while allowing the passage of alternating current (AC). For these devices when installed on boats, adherence to the standards set forth by the American Boat and Yacht Council (ABYC) is essential to ensure safety and reliability.

ABYC A-28 specifically addresses the installation and performance requirements for galvanic isolators. This standard provides guidelines on how these isolators should be wired, their testing criteria, and other important technical aspects necessary for maintaining the integrity of both the vessel and its electrical systems. Compliance with ABYC A-28 ensures that the galvanic isolators will effectively perform their intended function, reducing the risk of corrosion damage to the hull and other submerged metal components.

While UL standards, ISO standards, and ABYC E-11 are also important in different contexts related to electrical equipment and systems, they do not specifically address the requirements for galvanic isolators, making ABYC A-28 the appropriate standard for this specific application.
