Marinco CS504-50 EEL 50A 125V/250V Shore Power Cordset - 50' - Yellow

The Marinco CS504-50 EEL 50A 125V/250V Shore Power Cordset is a 50-foot marine shore power cable engineered for secure, one-handed connection at dockside. The EEL (Easily Engaged Lock) system uses an industry-first jaw-clamp design that eliminates the traditional locking ring, delivering a waterproof seal and reducing connection fumbles in rough water or low-light conditions. Built for harsh marine environments and UL-approved, this cordset addresses one of the most frequent pain points in boat dockside operation—reliable, corrosion-resistant power delivery without complexity.

The 50-amp, dual-voltage (125V/250V) rating accommodates both single and three-phase shore power pedestals found at modern marinas. The yellow jacket provides high visibility in dock areas and resists UV degradation from extended sun exposure typical on boats. Built-in cord lighting serves as a practical safety alert—boaters can instantly confirm the cordset is connected and drawing power, eliminating the guesswork that leads to dead batteries or electrical faults mid-cruise. At 45 pounds, the 50-foot length balances reach across typical dock spacing while remaining manageable for coiling and stowage in limited galley or cabin storage.

This cordset is essential for cruising and liveaboard boaters who depend on reliable AC shore power for refrigeration, climate control, and onboard systems during extended marina stays. Weekend anglers, trawler operators, and sailboat cruisers benefit from the durability and salt-air corrosion resistance engineered into Marinco's marine-grade construction. The one-handed operation is particularly valuable when managing lines, fenders, or other dock tasks simultaneously—a real-world advantage that standard cordsets lack. Whether operating from busy charter bases, remote anchorages with floating docks, or permanent slip assignments, the CS504-50 reduces the electrical troubleshooting and connection reliability issues that drain boating budgets and time on the water.
