Shore Power

Shore Power & Dockside Electrical

Shore Power Cords, Adapters, Inlets, Connectors & AC Protection

Shop shore power parts for safer dock connections, onboard charging, AC panels, and reliable power at the slip. Find 30 amp and 50 amp cordsets, EEL cordsets, straight adapters, pigtail adapters, Y adapters, reverse-Y adapters, inlets, receptacles, plugs, connectors, galvanic isolators, and installation support.

Match Before Ordering

Confirm amperage, voltage, locking pattern, plug style, cord length, boat-side inlet, dock pedestal connection, and whether you need a cord, adapter, inlet, or protection device.

Ask Parts Desk
Shore power cord and dockside electrical connection

Find Shore Power Faster

Search by Amperage, Voltage, Cord Type, Adapter Type, Inlet, or Brand

Use exact part numbers when possible. For matching by setup, search by terms like 30A cordset, 50A EEL cord, pigtail adapter, reverse Y adapter, shore power inlet, or galvanic isolator.

Amp & Voltage Matching

Start With 30A vs 50A and 125V vs 125/250V

Most shore power mistakes start with a mismatch at the dock pedestal, cord, adapter, or boat inlet. Confirm the service rating before buying. A 30A 125V setup is not the same as a 50A 125V or 50A 125/250V setup.

Cord Length & Connection Style

Match the Boat Inlet, Dock Pedestal, and Cord Run

Choose a cord length that reaches safely without strain, sharp bends, submerged sections, or overheated coils. Check the locking pattern, plug blades, threaded collar, sealing collar, and cord-end condition.

CORD

Cordsets

Use a full shore power cordset when the boat-to-dock connection needs the correct rating, length, plug style, and weather-resistant construction.

ADPT

Adapters

Use an adapter only when the dock-side and boat-side ratings and connector styles are understood. Never use an adapter to overload a cord or circuit.

INLT

Inlets

Replace worn, cracked, loose, overheated, or corroded inlets with the same rating and compatible connection style.

Protection & Safety

Dockside AC Power Should Be Matched, Protected, and Inspected

Shore power supports chargers, outlets, appliances, heaters, air conditioning, and AC panels while the boat is connected at the dock. Correct protection can include main breakers, ELCI or GFCI protection, galvanic isolation, reverse-polarity indicators, and clean wiring practices.

Inspect for heatReplace parts with burn marks, melted collars, loose blades, cracked housings, discoloration, or unreliable locking action.
Keep connections dryUse compatible collars, covers, caps, and strain relief so dockside power parts stay secure and protected.
Use qualified helpAC electrical work should follow current safety standards and be installed or inspected by qualified help when needed.

FAQ

Shore Power Buying Help

How do I choose the correct shore power cord?

Match the cord to your boat inlet and dock pedestal by amperage, voltage, plug configuration, locking style, cord length, and connection condition. Common setups include 30A 125V and 50A 125/250V service.

When should I use a pigtail, Y, or reverse-Y adapter?

A pigtail adapter changes one connection style to another. A Y adapter and reverse-Y adapter are used for specific split or combined shore power setups. These must be matched carefully to the boat system and dock service.

When should a shore power cord or inlet be replaced?

Replace shore power parts if they show heat damage, corrosion, cracked insulation, loose ends, burn marks, bent blades, damaged collars, or unreliable locking connections.

What does a galvanic isolator do?

A galvanic isolator helps reduce low-voltage galvanic current that can contribute to underwater metal corrosion while the boat is connected to shore power.
