The HBL303SS is a traditional metallic shore power inlet designed for marine applications. It features a 30A, 125V rating with a 2-pole, 3-wire grounding Twist-Lock configuration. The inlet is constructed with a metallic base and cover for strength, and its nickel-plated brass contacts provide corrosion resistance. A self-closing cover with a neoprene gasket ensures an IP56 rating for moisture resistance, protecting the interior from the elements. This UL and CSA approved inlet is ideal for adding a durable, watertight shore power connection to new or existing boats.
