Technical Specifications

Marina Power Distribution Solutions

Essential for versatile marine electrical connections:

• Boats with dual 30A shore power systems accessing 50A pedestals
• Temporary power distribution at marine events and boat shows
• Service yard applications requiring flexible power connections
• Emergency backup power distribution scenarios
• Marina infrastructure with mixed pedestal configurations
• Yacht club and marina facility power management

Electrical Load Management

The Y adapter configuration provides:

• Balanced Distribution: Each 30A output can handle up to 30A independently
• System Isolation: Separate circuits prevent cross-loading issues
• Maximum Utilization: Access to full 50A capacity when needed
• Load Flexibility: Different loads on each 30A circuit as required
• Safety Redundancy: Multiple circuits provide backup capability

Professional Marine Applications

Ideal for:

• Large Boats with Dual Systems: Yachts and powerboats with separate port/starboard shore power
• Service Applications: Marine service facilities needing flexible connections
• Temporary Installations: Event power distribution and temporary services
• Marina Operations: Facilities with mixed 30A/50A pedestal infrastructure
• Emergency Power: Backup power distribution during maintenance or outages

Installation & Safety Considerations

Professional installation guidelines:

• Load Calculation: Ensure combined load does not exceed 50A input capacity
• Circuit Protection: Verify appropriate overcurrent protection on each 30A circuit
• Grounding Verification: Confirm proper grounding continuity through adapter
• Connection Security: Ensure all twist-lock connections are properly engaged
• Environmental Protection: Position adapter to minimize exposure to spray and weather

ABYC Compliance & Marine Safety

This adapter supports ABYC E-11 compliance when properly installed and used within its ratings. The molded construction and marine-grade materials meet the durability and safety requirements for marine shore power applications.

Molded Construction Advantages

The molded Y design provides:

• Waterproof Integrity: No assembly joints to compromise water resistance
• Mechanical Strength: Single-piece construction withstands marine stresses
• Electrical Reliability: Integrated wiring eliminates connection points
• Corrosion Resistance: Sealed construction prevents internal corrosion
• Extended Service Life: Superior durability compared to assembled adapters

Marina Docking Efficiency

Streamline marina operations with:

• Reduced need for multiple pedestal types
• Improved slip utilization and flexibility
• Simplified power connection procedures
• Enhanced guest satisfaction through power availability
• Professional appearance and reliability

Frequently Asked Questions

Can I draw 30A from both outputs simultaneously?

Yes, you can draw up to 30A from each output as long as the total combined load does not exceed the 50A input capacity of the dock pedestal.

Is this adapter safe for permanent installation?

While built for durability, this adapter is typically intended for temporary connections. For permanent installations, consult a certified marine electrician and verify compliance with local codes.

Will this work with all 50A marina pedestals?

This adapter is designed for standard twist-lock connections. Most modern marinas use compatible configurations, but verify pedestal compatibility before connection.

How does load balancing work with this adapter?

Each 30A output operates independently. The electrical loads will automatically balance across the circuits, but manual load management may be needed to prevent overloading the 50A source.

Can I use this adapter in reverse (two 30A sources to one 50A load)?

No, this adapter is designed for one-directional use only - from single 50A source to dual 30A outputs. Reverse connection could create dangerous electrical conditions.

What maintenance is required for this adapter?

Regular visual inspection for cracks, corrosion, or damage. Clean connections periodically and verify twist-lock mechanisms operate properly. Store in dry conditions when not in use.
