Marinco Y504-2-30 EEL Shore Power Y-Adapter, 50 Amp 125/250V Male to Two 30 Amp 125V Female

The Marinco Y504-2-30 is a shore power Y-adapter that splits a single 50 Amp 125/250 Volt dock-side receptacle into two 30 Amp 125 Volt boat-side connections, letting a boat with two 30 Amp inlets draw power from one 50 Amp dock pedestal. The dock-side end is a locking 50 Amp 125/250 Volt male plug, and the boat-side end has two locking 30 Amp 125 Volt female connectors, each fitted with a sealing collar system for a waterproof connection.

This adapter uses Marinco's EEL (Easily Engaged Lock) design, a jaw-clamp connection system that allows one-handed engagement and forms a secure, waterproof seal without needing a separate locking ring. It is built with a yellow nylon housing to withstand harsh marine environments and is UL approved. The connector is a 2-pole, 3-wire configuration and supports splitting power between two boat inlets of similar or dissimilar power configurations.

Use the Y504-2-30 when your boat has two 30 Amp shore power inlets but the marina or dock pedestal only offers a 50 Amp 125/250 Volt outlet. It comes backed by a 1 year limited warranty.
