Marinco 32A Stainless Shore Power Inlet (AISI 316, 230V)

This Marinco 32A/230V stainless steel shore power inlet is a high-end solution for mid-sized yachts and motorboats that require reliable dockside electricity. It’s crafted from marine-grade AISI 316 stainless steel with a mirror-polished finish, which gives it a dual advantage: first, exceptional corrosion resistance and second, an elegant look that complements your vessel’s exterior design. Even with constant exposure to saltwater and humidity, this inlet will neither rust nor tarnish – it’s built to maintain its functionality and shine for years.

The inlet provides 32A, 230V AC – the standard supply for most mid-sized vessels using shore power. Its design is such that it also matches the standard for 50A/125V (US) systems, meaning you can physically plug a 50A/110V Marinco cord into it if needed (the electrical load remains equivalent). The built-in connector has three prongs: two carrying current and one for grounding. These prongs are made of brass with a nickel plating, which ensures optimal power transfer and shields them from corrosion (the nickel acts as a barrier to copper oxide formation). When you connect the shore power cord’s plug, its threaded collar firmly locks onto the inlet’s threaded body, meaning the connection is solid and resistant to wiggling or tension.

The inlet’s stainless steel lid is spring-loaded – as soon as you remove the plug, it snaps shut, protecting the interior. Under the lid lies a rubber O-ring that seals the interface and prevents water and dust ingress. This ensures that when no cable is connected, the electrical components remain safe even during heavy rain or ocean storms, meeting the IP56 standard. Installing this inlet is standard procedure: cut an appropriately sized hole, align the flange, and secure it with four screws (stainless screws are typically provided). On the interior side, hooking it up is made easy with clearly labeled screw terminals – Live (L), Neutral (N), and Ground (PE). This means a quick and error-free integration into the boat’s electrical distribution.

Applications & Recommendations:

• Mid-Sized Yachts & Cruisers: This 32A stainless inlet is ideal for vessels around 30–45 feet (9–14 m) in length that have several onboard systems like a single air conditioner, galley appliances, battery charger, lighting, and other devices. It will safely and efficiently deliver shore power to all of them.
• Premium Choice: Choosing a stainless inlet is often about both functionality and aesthetics. If you value top-tier performance and appearance for your boat, this product offers marine-grade reliability and a luxury detail on your deck.
• Upgrading: Many boat owners replace standard plastic inlets with stainless for added security and longevity. The mounting parameters between the Marinco Valox inlet (code 14.634.30) and this model are identical, so upgrading is straightforward – you gain improved durability without needing to modify the deck cutout.
• Maintenance: Although stainless steel is resilient, it benefits from routine cleaning. Rinse the flange and lid with fresh water after periods of heavy salt spray to remove the salt film. You can use a stainless steel cleaner to restore shine periodically. Also, keep an eye on the rubber O-ring – if you notice cracks or stiffening, replace it to maintain a 100% watertight seal.
• Always Ready: Keep the lid closed whenever you’re not connected to shore. It sounds simple, but it’s crucial for protecting the inlet. When preparing to plug in, make sure you develop a good habit of tightening the plug’s locking ring – this small step prevents big problems, like unwanted disconnections or water intrusion if the cord gets jostled.
