AFI 15A & 20A Products & Dockside Boxes

AFI in 15A & 20A Dockside Power

AFI is a long-established name in marine electrical equipment, with a catalog that spans shore power, horns, wipers and 12V accessories. Within the lower-amperage end of shore power, AFI's 15A and 20A products serve a practical purpose: they connect small boats, personal watercraft, skiffs and workshop or garage setups to household-style AC power in a way that is built for wet, salty, UV-heavy conditions. This page focuses on that specific slice of the AFI lineup. For the wider range of what the manufacturer offers, visit the AFI brand page.

Why 15A and 20A Shore Power Gear Matters

Standard household plugs and boxes are not designed for docks. Moisture, corrosion, vibration and temperature swings can degrade ordinary connectors, leading to heat buildup, intermittent power or shock hazards. Marine-rated 15A and 20A components use corrosion-resistant metals, sealed housings and weatherproof covers to keep the connection safe and reliable. A properly rated dockside box also gives you a defined, protected place to mount a receptacle on a dock, seawall or boathouse wall rather than leaving a connection exposed to spray and rain.

Lower-amperage shore power is typically used for battery chargers, bilge-related accessories, lighting, small refrigeration and tools. It is not intended for heavy loads such as air conditioning, so matching the connection to what you actually plan to run is the first step in a safe setup.

What to Look for in AFI Dockside Boxes and Receptacles

AFI products in this category are part of the same family as Marinco, whose shore power connectors are widely recognized across marinas. When comparing 15A and 20A parts, consider these points:

• Amperage and voltage rating: Confirm the device matches your circuit and the plug configuration on your cord or adapter.
• Housing material: Corrosion-resistant reinforced nylon and stainless or nickel-plated contacts hold up better in marine air than standard electrical hardware.
• Weatherproof covers: A self-closing or gasketed cover keeps water out when the receptacle is not in use.
• Mounting style: Surface-mount boxes suit docks and walls, while flush-mount inlets are installed in a hull or bulkhead.
• Certifications: Look for UL listing and compliance with ABYC guidance when wiring a marine installation.

Choosing the Right Fit

Before you buy, check your dock pedestal or home circuit, the cord ends you already own, and whether you need adapters to step between 15A, 20A and 30A configurations. Use wire of an appropriate gauge, keep terminations tight, and add GFCI protection wherever AC power meets a wet environment.
