AFI S20-30 Marine Power Adapter 20A to 30A 125V Locking

The AFI S20-30 marine power adapter provides a reliable connection solution for converting 20-amp shore power to 30-amp boat systems. This straight adapter features a dock-side male 20A/125V locking plug that connects to a boat-side female 30A/125V locking receptacle, allowing you to safely use lower-amperage shore power when 30-amp service is not available.

Key Features:

• Ergonomically designed one-piece construction for durability and ease of use
• Built-in LED power indicator confirms active electrical connection
• Marine UL® listed for quality and safety compliance
• 20A/125V locking male plug (dock side) to 30A/125V locking female connector (boat side)
• Marinco-compatible design replaces older 84A style adapters

Important Installation Notes:

This adapter does not feature sealing collars and is designed for use in protected, dry locations only. It should not be used in wet or exposed areas where moisture could compromise the connection. When using this adapter, your available power is limited to the 20-amp shore power supply—do not exceed 20 amps of total load on your boat's electrical system.

Ideal for marinas and docks where only 20-amp service is available but your vessel is equipped with a 30-amp power inlet. The built-in LED indicator provides instant visual confirmation of shore power connection.
