Marinco Y504-2-30 EEL (2)-30A-125V Female to (1)50A-125/250V Male "Y" Adapter - Yellow

The Marinco Y504-2-30 EEL "Y" Adapter is a marine-grade electrical distribution connector designed to split a single 50A dockside power source into dual 30A boat-side circuits. This dual-connector configuration allows vessels with twin electrical systems—or boats operating with split-phase loads—to draw power simultaneously from a single pedestal without exceeding amperage limits on either feed line. The adapter's integrated sealing collar system keeps moisture and salt spray away from connection points, critical for maintaining electrical integrity in wet marine environments.

The male connector accepts standard 50A-125/250V dockside receptacles (NEMA 14-50R equivalent), while the dual female connectors deliver 30A-125V output through Marinco's locking collar design, preventing accidental disconnection underway or during rough seas. Each female outlet features a sealing collar that compresses around the cordset when fully seated, creating a weather-resistant seal that protects against corrosion-causing moisture infiltration—essential in salt air environments where oxidation accelerates connector degradation. The 7.2-pound construction provides robust mechanical stability for heavy-gauge power cords.

This adapter serves boats equipped with separate 30-amp circuits for engine systems and hotel loads, eliminating the need for dual shore power pedestals at crowded marinas. It's particularly valuable for larger cruising vessels, trawlers, and commercial fishing boats that operate independent electrical subsystems. The split-phase configuration also accommodates vessels transitioning from older single-feed systems to modern dual-feed installations without requiring complete electrical infrastructure overhaul.

Marinco adapters comply with ABYC (American Boat and Yacht Council) marine electrical standards and are listed for wet-location use per UL specifications. The product's yellow color provides high visibility at dockside, reducing the risk of tripping hazards and accidental disconnection during crew movement on crowded piers.
