⚠️ Critical Installation Requirement

IMPORTANT: This adapter MUST be connected to an onboard center-tapped isolation transformer or shore power converter. DO NOT use this adapter without proper isolation equipment. Failure to comply can result in dangerous electrical conditions.

Intelligent Safety Logic System

The YQ100PLUS incorporates advanced logic sensing that continuously monitors electrical conditions and connection status. The system verifies that both plugs are fully engaged, confirms correct dockside polarity, and ensures proper phase relationships between dual receptacles before allowing power transfer.

Versatile Dual-Mode Functionality

The adapter's "A" leg design enables connection to a single 50A, 125/250V receptacle for standard adapter operation, or dual 50A receptacles for 100A vessel power. This flexibility accommodates various marina configurations and power requirements without requiring multiple adapters.

Advanced Safety Monitoring Features

  • Full Engagement Detection: Ensures both plugs are completely connected
  • Polarity Verification: Confirms correct hot and neutral wiring
  • Phase Matching: Verifies proper phase relationships between receptacles
  • Visual Indicators: LED lights confirm safe operation status

Professional Construction Quality

Featuring fully molded Hubbell plugs and connectors, the YQ100PLUS eliminates potential failure points common in assembled adapters. Cord clamps prevent terminal strain, while the environmentally sealed enclosure provides protection against marine weather conditions.

Marine Power Applications

  • High-Demand Vessels: Powers boats requiring 100A shore connections
  • Marina Flexibility: Adapts to marinas with only 50A service
  • Backup Power Options: Provides redundancy for critical electrical systems
  • Charter Operations: Enables operation at various marina configurations

Frequently Asked Questions

Why is an isolation transformer required?

An onboard isolation transformer or converter is essential for safe operation when combining two separate shore power sources. This prevents dangerous ground loops and ensures proper electrical isolation.

How does the single 50A mode work?

The "A" leg plug can connect to a single 50A receptacle, allowing the adapter to function as a standard 50A shore power connection when dual receptacles aren't available.

What do the indicator lights show?

The indicator lights verify correct polarity at the dock receptacles, confirm proper phase relationships, and indicate when both plugs are fully engaged and the system is operating safely.

Can I use this without an isolation transformer?

No, this adapter must never be used without proper onboard isolation equipment. Operating without isolation transformers can create dangerous electrical conditions and violate safety standards.
