Hubbell has built rugged electrical connections since 1888, and its marine line brings that reliability to the dock. This collection covers shore power cordsets, adapters, inlets and back boxes in 30A and 50A configurations.
Setting Up Hubbell Shore Power
Start by matching the amperage of your boat inlet to the dockside pedestal. Most recreational boats use a 30A 125V connection, while larger vessels and those with more onboard loads run 50A at 125V or 250V. Using the right cordset keeps your connection safe and prevents voltage drop.
Cordsets, Adapters and Back Boxes
Cordsets come in 25 foot and 50 foot lengths so you can reach the pedestal without strain. Adapters let you connect when the dock and boat ratings differ, such as a 30A boat to a 15A household outlet. Back boxes and boots seal the inlet against weather. Match every part to your amperage and voltage before you plug in.
Frequently Asked Questions
What amperage shore power do I need?
Most small to mid-size boats use 30A 125V. Larger boats with air conditioning, water heaters and multiple loads often need 50A at 125V or 250V. Match the boat inlet to the dock pedestal.
Can I use a Hubbell adapter between different ratings?
Yes. Hubbell makes adapters to bridge common mismatches, such as a 30A boat connecting to a 15A household outlet. The adapter does not increase available power, it only changes the plug type.
What length cordset should I buy?
Choose a length that reaches the pedestal with a little slack but without long coils on the dock. Hubbell offers 25 foot and 50 foot cordsets to suit most slips.
