Overview / What Is Newmar GI-60-FS Isolator?

The Newmar GI-60-FS 60A Galvanic Isolator with Fail Safe is an advanced protective device installed between the shore power ground and the boat’s ground system. It works by blocking low-voltage DC currents that cause galvanic corrosion while still allowing higher fault currents to pass through in case of an electrical emergency. This ensures both safety and protection for the vessel’s metal parts, propellers, shafts, and hull fittings.

Galvanic corrosion occurs when dissimilar metals are connected in a conductive environment like seawater. The isolator prevents this destructive electrolysis without compromising the grounding safety of the boat. Its fail-safe feature ensures that, even if the isolator fails, the ground connection remains intact, maintaining the required safety standards.

Key Features of Newmar GI-60-FS 60A Galvanic Isolator with Fail Safe

• 60A continuous rating for high-capacity protection
• Fail-safe circuitry ensures grounding remains functional in case of isolator failure
• Marine-grade construction designed to withstand harsh saltwater environments
• Easy installation with minimal maintenance required
• Compliance with ABYC standards ensuring top-notch safety

How Does Newmar GI-60-FS Isolator Work?

The isolator uses semiconductor diodes arranged to block low-level DC galvanic currents while allowing AC fault currents to flow freely to the ground. When a hazardous fault current is detected, the device’s fail-safe circuitry bypasses the diodes, ensuring the boat’s safety remains uncompromised. This innovative design combines corrosion prevention with safety compliance, making it one of the best isolators in its class.

Unlike traditional zinc anodes, which sacrifice themselves to protect metals, the Newmar GI-60-FS provides continuous, maintenance-free protection without the need for frequent replacement. This makes it a cost-effective and long-lasting solution.

Benefits of Installing Newmar GI-60-FS 60A Galvanic Isolator

Installing this isolator on your vessel provides several significant benefits:

1. Extended lifespan of underwater metals by preventing galvanic corrosion.
2. Improved safety through its fail-safe grounding feature.
3. Cost savings on expensive repairs caused by corrosion damage.
4. Peace of mind for boat owners using shore power at various marinas.

Installation Guide: How to Install Newmar GI-60-FS Isolator

Installing the Newmar GI-60-FS 60A Galvanic Isolator with Fail Safe is straightforward but should be performed by a qualified marine electrician. Here are the key steps:

• Disconnect shore power completely before installation.
• Mount the isolator securely in a dry, well-ventilated location near the shore power inlet.
• Connect the isolator in line with the green grounding wire between the inlet and the boat’s grounding system.
• Ensure all connections are tight and corrosion-free.
• Test the system to confirm proper functioning before reconnecting shore power.

Warning: Improper installation can compromise both safety and protection. Always hire a certified marine electrician to avoid potential hazards.

Maintenance Tips

The Newmar GI-60-FS isolator requires minimal maintenance. However, periodic inspections are essential to ensure optimal performance:

• Inspect connections annually for corrosion or looseness.
• Check the fail-safe functionality during routine electrical maintenance.
• Keep the isolator dry and away from direct water spray.
• Follow manufacturer’s guidelines for long-term care.

Detailed FAQ Section

1. What is the purpose of the Newmar GI-60-FS 60A Galvanic Isolator?

The primary purpose of the Newmar GI-60-FS isolator is to prevent galvanic corrosion, which occurs when dissimilar metals on a boat are exposed to seawater while connected to shore power. This corrosion can lead to severe damage to propellers, shafts, and other metal fittings. By blocking low-voltage DC currents that cause galvanic corrosion, the isolator ensures your vessel remains safe and protected. Additionally, its fail-safe mechanism guarantees that grounding remains intact even if the isolator itself fails, maintaining ABYC safety standards. This dual functionality makes it a critical device for any boat using shore power regularly. Proper installation by a marine electrician enhances its performance and reliability, ensuring long-term protection.

2. How does the fail-safe feature work in this isolator?

The fail-safe feature in the Newmar GI-60-FS 60A Galvanic Isolator ensures continuous protection by maintaining the ground connection even if the internal diodes fail. This is achieved by an internal bypass circuit that automatically engages when a fault is detected, allowing fault currents to flow safely to the ground. This prevents electrical hazards and keeps the boat compliant with safety regulations. The fail-safe design is particularly important in marine environments, where electrical faults can have catastrophic consequences. Boat owners can rest assured that, even in the rare event of an isolator failure, their vessel’s grounding system will continue to function properly, safeguarding both equipment and passengers.

3. Is the Newmar GI-60-FS isolator compatible with all boats?

Yes, the Newmar GI-60-FS isolator is compatible with most boats equipped with shore power connections. It is designed to handle up to 60A continuous current, which is suitable for a wide range of vessels, including sailboats, motor yachts, and commercial boats. However, it is essential to verify your boat’s electrical specifications before installation to ensure compatibility. The isolator meets ABYC standards, making it a reliable choice for different marine applications. When in doubt, consult with a marine electrician who can assess your boat’s electrical system and confirm whether this model is the right fit. Proper installation and periodic inspections will maximize its effectiveness and longevity.

4. What are the maintenance requirements for this isolator?

The Newmar GI-60-FS isolator is designed to be low-maintenance, but routine checks are essential for optimal performance.
