Description
GI-30-FS Galvanic Isolator 30A Fail Safe Installing the Galvanic Isolator between the AC safety ground and DC bonding system blocks most of the low-voltage currents and corrosive action seen on the vital metallic components in the saltwater. With the low voltage current blocked, the galvanic corrosion effect on the sacrificial anodes is significantly reduced, while the integrity of the critical safety ground path is maintained.
This means a significant saving in boat haul-out fees and zinc replacement costs. For additional safety, all units feature a large capacitor, providing a secondary low-impedance path for sending AC current to the ground.
Newmar’s latest galvanic isolator meets the latest ABYC A-28 2019 requirements, including being a failsafe. This design can meet the strictest temperature and current tests to create a robust solution for galvanic protection.
Features: Protects against corrosion Maintains a safe environment Certified to the UL1500 standard for Ignition Protection Tested to a 50 degrees C ambient temperature The 30A fail-safe feature ensures ground maintenance Connection in the event of isolator failure Specifications: Shore Power Voltage: 115–230V Maximum Short Circuit: 5000 Amps Stray Current Protection: Up to 1. 4 VDC Dimensions (LxWxH): 200 x 189 x 68.

Electrical — frequently asked
- What’s the difference between marine wire and regular wire?
- Marine wire uses tinned (tin-coated) copper strands that resist the corrosion salt air causes, and it’s more finely stranded so it flexes with vibration without breaking. Standard automotive or household wire corrodes and fails much faster in a marine environment.
- How do I size a fuse for a marine circuit?
- Size the fuse to protect the wire, not just the device. Match the fuse rating to the wire gauge’s safe current capacity so the fuse blows before the wire overheats. When adding a new circuit, follow the wire manufacturer’s ampacity chart for the gauge and run length you’re using.
- Do I need a battery switch on my boat?
- A marine battery switch is strongly recommended. It lets you disconnect the battery for storage or service, isolate a failed battery, and — on multi-battery setups — choose which bank powers the boat. It’s a core safety and reliability component.
