Your boat's shore power connection deserves reliability. Sierra's 30A/125V inlet combines marine-grade 316 stainless steel with a weatherproof design that handles saltwater exposure. The self-holding cap stays open when you need it, while the rear enclosure shields electrical components from the elements. Nickel-plated brass terminals and a secure 3-wire locking connector ensure safe, corrosion-resistant power delivery. ETL Listed to meet UL and CSA regulations
