Marinco 50Amp 125/250V Shore Power Cable - 25' - White

The Marinco 50Amp 125/250V Shore Power Cable in 25-foot white is the hardworking connection every serious boater needs between their vessel and the dock. Whether you're running a cabin cruiser, sportfisher, or any RV-style marine installation, this marine-grade cord delivers reliable 50-amp service to power air conditioning, galley appliances, heating systems, and all auxiliary electronics simultaneously. Built to Marinco's reputation for durability, this shore power cable handles the high amperage demands of modern boats while resisting salt spray, UV exposure, and the constant flex of daily dock use.

This cordset features a watertight molded plug and connector assembly engineered specifically for marine environments, preventing moisture intrusion that could compromise safety or performance. The four-wire (4-wire) construction—supplying both 125V and 250V simultaneously—allows you to operate high-power loads without voltage drop or circuit conflicts. At 23.5 pounds, the 25-foot length provides ample reach from typical dock pedestals to your boat's inlet without excess bulk, while the white jacket resists heat absorption and offers superior visibility in variable lighting. Marinco's marine-grade insulation and molded connections meet or exceed ABYC (American Boat and Yacht Council) standards, ensuring your electrical system operates safely under salt water conditions.

Ideal for cruisers planning extended dock stays, commercial fishing operations, or any boater upgrading from undersized shore power systems, the Marinco 50Amp cord eliminates power-sharing between major systems. The 25-foot length suits most modern slips and marina configurations, while the durable construction withstands repeated coiling, uncoiling, and seasonal storage without cracking or stiffening. Installation is straightforward—simply connect to your boat's 50-amp inlet and the pedestal receptacle—though professional inspection is recommended for first-time installations to verify proper grounding and breaker configuration at the dock.
