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

The Marinco 50Amp 125/250V Shore Power Cable in white is a 50-foot marine-grade cordset engineered for safe, reliable power delivery to vessels at dock. This 50-amp 125/250-volt shore power cable features Marinco's PowerCord Plus construction, delivering the heavy-duty electrical connectivity that liveaboards, cruisers, and serious fishermen depend on when plugged into marina pedestals and shore power facilities. The 6-gauge marine-grade cable handles the full amperage demands of modern boat electrical systems without voltage drop over extended distances.

Constructed with watertight molded plug and connector assemblies, this 50-foot shore power cord resists corrosion and salt-air degradation—critical in marine environments where standard electrical cables deteriorate rapidly. The molded connection points eliminate water infiltration that can cause arc faults or equipment damage. At 45.55 pounds, the cable maintains the flexibility needed for routine coil and storage without cracking the jacket or internal conductors. The standard threaded ring design provides compatibility with common marina inlet configurations, eliminating the need for adapters on most modern vessels.

This shore power cable is essential for anyone keeping a boat at a marina, whether for weekend getaways or full-time liveaboard use. Anglers running offshore trips rely on dependable 50-amp service to operate navigation electronics, refrigeration, air conditioning, and battery chargers without risk of power interruption. The 50-foot length bridges most dock-to-vessel distances while the heavy 6-gauge conductors handle simultaneous load demands that smaller cordsets cannot support. Replacement or backup shore power cables wear out from UV exposure, salt spray, and repeated coil-uncoil cycles—having a verified marine-grade spare eliminates the risk of being stranded without shore power.

Marinco shore power cordsets are engineered to ABYC (American Boat and Yacht Council) electrical standards, ensuring that gauge, insulation, and connector design meet the safety requirements for marine DC and AC power systems. The nickel-plated brass connectors resist corrosion far longer than standard brass or aluminum alternatives, critical in saltwater moorings where electrolytic degradation can seize connections or create high-resistance joints that generate dangerous heat.
