Marine Shore Power

Shore Power

Keep your boat connected to reliable dockside electricity with quality marine shore power components, including cordsets, inlets, adapters, connectors, and accessories. Designed for marine applications, these products help provide dependable electrical connections while standing up to the moisture, vibration, corrosion, and demanding conditions commonly encountered around docks and on the water.

Shore Power for Boats: Reliable Dockside Electrical Supply

When your boat is connected at the dock, shore power provides access to AC electrical power for many onboard systems and equipment. Depending on the vessel and electrical configuration, shore power may be used to operate or support battery chargers, air conditioning, galley appliances, entertainment systems, electronics, and other onboard equipment.

Using components specifically designed and rated for marine applications is important when working with dockside electrical systems. Marine-rated shore power equipment is designed with features intended to withstand exposure to moisture, saltwater environments, vibration, and frequent connection and disconnection.

The correct shore power components should always be selected based on your boat's electrical system, the dock's available power supply, and the manufacturer's specifications.

What Does a Shore Power System Include?

A typical boat shore power system may include:

Dockside power pedestal — Common configurations in North America include 30-amp and 50-amp service, although available voltage and configurations can vary.
Shore power cordset — Typically includes heavy-duty marine cable and compatible connectors or plugs designed for dockside use.
Boat-side inlet — A matching inlet or receptacle installed on the vessel to connect the shore power cord.
Adapters and accessories — Depending on the application, these may include adapters, extension products, replacement connectors, covers, and related electrical accessories.
Circuit protection and safety equipment — Appropriate breakers, protection devices, and other equipment may be required depending on the vessel's electrical system and applicable requirements.

Why Shore Power Component Quality Matters

Shore power involves AC electrical power in a wet marine environment, making proper equipment selection, installation, and maintenance especially important.

Quality marine shore power components are designed to help address common marine conditions such as:

Moisture and water exposure
Saltwater and corrosive environments
Vibration and movement
Repeated connection and disconnection
Seasonal and extended dockside use
The electrical demands of onboard equipment

Always verify that shore power cords, inlets, adapters, connectors, and other components have the correct ratings and are compatible with your vessel and dockside electrical service. Inspect equipment regularly for signs of corrosion, overheating, damaged insulation, loose connections, or other deterioration, and discontinue use of damaged equipment.

Important: Shore power equipment should be installed, operated, and maintained in accordance with the applicable manufacturer's instructions and applicable marine electrical requirements. When in doubt, consult a qualified marine electrician.
