GFCI (Ground Fault Circuit Interrupter) breakers are designed to trip when they detect a fault current flowing to ground. But boat owners often find GFCIs tripping more often than expected.

Common reasons include:

• Neutral-to-ground connections onboard (common in older boats).
• Stray currents from other boats.
• Damaged shore cords or connectors.
• Reverse polarity wiring at the dock pedestal.

How can you reduce nuisance trips?
✅ Use a marine isolation transformer to break the electrical connection with shore ground.
✅ Inspect cords regularly for wear and corrosion.
✅ Use a polarity tester before plugging in.
✅ Verify your onboard AC system wiring meets current standards.

Pro Tip:
ANG Shore Power Converters™ include built-in isolation and advanced protection, reducing the chance of GFCI trips and ensuring stable power delivery.
