Marinco 50A 125V Shore Power Cable - 50' - Yellow

The Marinco 50A 125V Shore Power Cable in yellow delivers reliable, marine-grade electrical connectivity for RVs, boats, and other vessels requiring 50-amp service. This 50-foot cordset is engineered to withstand saltwater environments and extended outdoor exposure, making it essential equipment for liveaboard cruisers, weekend boaters, and offshore fishing operations where shore power reliability directly impacts comfort and safety on the water.

Built to Marinco's PowerCord Plus standards, this cable features 6-gauge heavy-duty conductor wire rated for 50-amp 125-volt service, delivering the amperage capacity necessary for marine electrical systems without voltage drop over its full 50-foot length. The watertight molded plug and connector design prevents water intrusion and corrosion—critical in salt-air environments where standard electrical cords fail prematurely. An integrated LED power indicator light provides immediate visual confirmation that shore power is active, eliminating guesswork during dockside connections. Contoured grip ends reduce hand fatigue during setup and breakdown, and the super-flexible cable design simplifies storage in tight locker spaces and routing through tight quarters on deck.

This 50A shore power cable is designed for captains and vessel owners who demand durability and safety in their dockside power setup. Whether powering air conditioning, refrigeration, battery chargers, or full electrical loads during extended mooring, the 50-foot length reaches most standard marina pedestals without extension, eliminating chained cordsets that introduce failure points. The yellow color aids visibility during nighttime docking operations and makes the cable easier to locate among other deck equipment.

Marine shore power cords are critical infrastructure for vessel electrical systems. The 50-amp 125-volt standard is the most common marine service configuration, compatible with nearly all modern boat pedestals and RV hookups. Upgrading to marine-grade construction—as opposed to standard RV or household cords—ensures the connector and cable withstand UV exposure, salt spray, and thermal cycling that rapidly degrades non-marine equipment.
