Marinco 6365CRN 50A 125/250V Locking Shore Power Plug, 3-Pole 4-Wire, Yellow Nylon

The Marinco 6365CRN is a 50 amp, 125/250 volt locking shore power plug built for connecting a boat's shore power cordset to marine power sources at the dock. It is a male, 3 pole, 4 wire locking blade design, so once inserted and twisted into a matching locking receptacle it stays securely seated even with cord movement, vibration, or wind loading at the slip. The body is molded from yellow nylon, a durable, corrosion-resistant material that stands up to sun, salt spray, and repeated handling better than lighter-duty plastics. Internally, the contacts and terminals are corrosion resistant, which helps maintain a reliable electrical connection over time in a wet marine environment. The exterior of the plug features a ribbed grip design so it can be twisted on and off by hand without tools, even when hands are wet or gloved. This plug is UL listed, confirming it has been tested to recognized safety standards for electrical connectors. It is intended for use as the boat-side (male) connector on a 50A 125/250V shore power cordset, mating with a corresponding 50A locking shore power inlet or receptacle. Boat owners, marina operators, and cordset assemblers use this plug when building, repairing, or replacing 50 amp shore power cords.
