The Smartplug Shore Power Systems connector is designed to provide better protection for your boat against loose connections and corrosion. Unlike traditional twist-type plugs, its pin-and-clip design delivers more than 20 times the metal-to-metal contact, reducing the chance of fire due to resistance and overheating.
Three weatherproof seals ensure a safe, dry connection. Available in 30- or 50-amp versions with stainless steel, black, white, or gray nonmetallic covers.
