A boat isolation transformer is a vital device that protects marine electrical systems by isolating the boat’s power supply from shore power. It prevents galvanic corrosion and electrical hazards, ensuring the safety of onboard electronics and personnel. By providing a dedicated power source, it eliminates ground loops and enhances overall system reliability. Commonly used in yachts and larger vessels, this transformer offers improved safety, reduced interference, and better protection against electrical faults, making it essential for marine power systems.
