Marinco 305CRCN 30A 125V Locking Female Shore Power Connector

The Marinco 305CRCN is a 30 amp, 125 volt locking female shore power connector used to bring dockside electrical power onto a boat. As the female half of a locking blade connection, it mates with a matching male shore power plug to create a secure, weatherproof electrical connection that resists accidental disconnection from vibration, wave motion, or dock traffic. The connector body is molded from yellow nylon for high visibility on deck and resistance to marine environments, and it features a ribbed housing design that gives users a secure, confident grip when connecting or disconnecting shore power cords. Internally, the contacts and terminals are corrosion resistant, an important feature given the connector's constant exposure to moisture, salt air, and temperature swings around docks and marinas. The connector is configured with 3 poles and 3 wires to handle standard 30 amp shore power circuits, and it is listed to UL and cUL safety standards for marine and marine-adjacent electrical equipment. This connector is commonly used as a replacement or upgrade component for boat owners rewiring or repairing their shore power inlet system, or for anyone assembling a shore power cord set. At 0.33 pounds, it is a lightweight, compact fitting that installs into standard shore power cordage and connector assemblies.
