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

The Marinco 50Amp 125/250V Shore Power Cable in 50-foot length is the workhorse connection every serious boater and liveaboard needs for reliable, safe onshore power delivery. Whether you're docking at a marina for the season or plugging in at a temporary slip, this marine-grade cordset bridges the gap between your vessel's electrical system and fixed shore infrastructure. Built to withstand the salt spray, UV exposure, and constant thermal cycling that define life on the water, this cable delivers consistent power to everything from air conditioning and refrigeration to battery chargers and galley appliances—without the voltage drop or safety compromises that plague inferior alternatives.

The Marinco 50Amp 125/250V Shore Power Cable features four-wire construction and a watertight molded plug and connector design that eliminates corrosion points and keeps saltwater intrusion at bay—critical for long-term reliability in marine environments. The 50-foot length provides flexibility in positioning your boat relative to shore pedestals while the heavy-gauge conductors minimize voltage sag over distance, ensuring your appliances receive full rated power. High-visibility yellow jacket makes the cable easy to locate and route across busy dock areas, reducing tripping hazards and theft risk. All components meet or exceed ABYC and UL standards, and the durable exterior resists cracking, abrasion, and UV degradation over years of daily use.

Liveaboards and cruising boaters who demand uninterrupted power for climate control and refrigeration will appreciate the robust 50-amp capacity and marine-specific engineering that keeps this cable performing in the harshest conditions. The 50-foot working length accommodates most standard marina slip configurations without requiring daisy-chaining or adapters that introduce failure points. Installation is straightforward with standard shore power pedestals, though proper grounding and polarity checks are essential—consult your vessel's electrical manual or a qualified marine electrician if unfamiliar with shore power connections. This cable represents a long-term investment in safe, reliable power delivery and is essential backup or primary equipment for any serious offshore or coastal boating operation.
