Marinco 15A & 20A Marine Electrical Products
When it comes to keeping your boat safely connected to shore power, the quality of your electrical components is non-negotiable. Marinco 15A and 20A products represent the entry-level shore power tier that serves the vast majority of recreational boaters — from small runabouts and day cruisers to pontoon boats and modest sailboats. These products cover everything needed to safely deliver 125V AC power from the marina pedestal to your vessel, including plugs, connectors, locking duplex receptacles, GFCI outlets, marine-grade extension cords, and weatherproof covers.
Why 15A and 20A Shore Power Matters
Shore power allows boaters to run onboard AC appliances, charge batteries, power air conditioning, and operate entertainment systems without relying solely on a generator or the boat's own battery bank. The 15A and 20A ratings are standard for smaller vessels and are directly compatible with typical marina pedestals, making them the most universally applicable shore power tier.
What sets marine-grade 15A and 20A products apart from their household counterparts is their design for the marine environment. From inlets and cordsets to adapters and accessories, Marinco solutions boast marine-grade components, corrosion-resistant materials, and feature-rich designs, ensuring you're always equipped to connect to shore power sources. In a saltwater or high-humidity environment, standard household electrical fittings simply won't hold up — corrosion, moisture intrusion, and UV degradation can create dangerous conditions aboard.

Key Considerations When Shopping
Before purchasing 15A or 20A shore power components, confirm your boat's existing inlet amperage rating and match your components accordingly. Also verify that any receptacles or covers you choose are rated for wet or damp locations — look for IP56 or equivalent marine ratings. GFCI protection is strongly recommended for any receptacles installed in the cockpit or other exposed areas.
