Many yacht owners are familiar with the problem of corrosion, but few realize that electrical grounding plays a big role. One of the most effective tools to prevent galvanic corrosion is an isolation transformer.

What is Galvanic Corrosion?
Galvanic corrosion happens when two dissimilar metals are immersed in an electrolyte (saltwater) and electrically connected. This creates a current that slowly dissolves the less noble metal—damaging props, shafts, and thru-hulls.

How Shore Power Worsens Corrosion
When your boat is plugged into shore power, your AC ground wire is bonded to the marina’s grounding system. If neighboring boats or dock wiring have different electrical potentials, your boat can become the unintended path for stray currents.

How Isolation Transformers Help
An isolation transformer:

• Breaks the electrical connection between shore ground and the vessel
• Eliminates the path for galvanic currents to flow from shore
• Provides a safer power connection by preventing stray AC currents
• Reduces nuisance GFCI tripping

ANG Iso-Boost Transformers
ANG ISO-BOOST™ transformers combine galvanic isolation with automatic voltage boosting, protecting both your equipment and your hull. They are lighter and more efficient than traditional laminated transformers and include features like soft start and overload protection.

Additional Benefits

• Reduces corrosion-related maintenance
• Extends the life of underwater metals
• Enhances safety for swimmers near your boat

Recommendation
If your boat stays plugged in at the dock for long periods or you notice zincs deteriorating quickly, installing an isolation transformer is essential.

Voltage drop is a common issue in marine shore power systems, especially when using long shore cords or when marinas have aging infrastructure. Understanding how voltage drop works helps you avoid equipment problems and maintain safe electrical operation.

What is Voltage Drop?
Voltage drop occurs when the electrical potential decreases along the length of a conductor. As current travels through the shore cord, resistance causes a reduction in voltage at the point of use.

Why It Matters
Too much voltage drop can cause:

• Equipment malfunction or failure
• Dimming lights
• Overheating of electrical components
• Tripping of breakers

Marine standards like ABYC E-11 recommend limiting voltage drop to 3% for critical circuits and 10% maximumfor non-critical loads.

Factors That Influence Voltage Drop

• Length of the shore cord: Longer cords create more resistance.
• Cable size (AWG): Smaller wires have higher resistance.
• Current draw: Higher loads increase voltage drop.
• Connection quality: Corroded or loose plugs create additional resistance.

Example:
A 100-foot 2 AWG shore cord carrying 80 amps at 240V can have up to 6–8% voltage drop, depending on the load and connector condition.

How to Minimize Voltage Drop

• Use the shortest practical shore cord.
• Choose larger cable sizes (2 AWG or larger for high loads).
• Keep all plugs and receptacles clean and corrosion-free.
• Avoid coiling cables tightly, which can increase heat.

ANG Solutions
ANG marine power cords are built with heavy-duty copper conductors and low-resistance terminations to reduce voltage drop. Combined with ANG Shore Power Converters™, you can count on stable output voltage, even if shore power fluctuates.

Tip:
Always check voltage under load with a multimeter at the inlet to confirm performance.
