Marinco EEL Pigtail Adapter P503-30, 50A 125V Female to 30A 125V Male Shore Power Dock Adapter

The Marinco P503-30 Eel Pigtail Adapter is a shore power adapter that converts a 50 amp, 125 volt female shore power connection to a 30 amp, 125 volt male plug, letting a boat wired for a 30 amp shore power cord connect to a 50 amp dock pedestal outlet. Marinco Eel adapters use a compact, straight blade design with a molded plastic body built for the marina environment, where dock power outlets and boat shore power cords do not always match amperage. This adapter is UL listed and rated for residential grade shore power use, with 3 poles and 3 wires to carry hot, neutral, and ground safely between the dock connection and the boat's shore power inlet. The black plastic housing is sized for the demands of dock and marina use, and the short pigtail design keeps the adapter compact and easy to store in a dock box or lazarette when it is not connected. This is a single-piece inline adapter, not a full replacement shore power cord, so it is meant to be used between an existing 30 amp boat shore power cord and a 50 amp dock outlet. It weighs 3.1 pounds.
