Boat Shore Power Connection Calculator

Quickly estimate the approximate shore power connection capacity required for your boat

You can estimate the required shore power pedestal connection capacity based on either the total power demand or the equipment used on board.

Provides a preliminary evaluation for 16A–63A single-phase boat and marina connections. Above 63A and three-phase applications are evaluated on a project basis.

Calculation Options

Calculation by Total Power

Use this option if you already know the estimated total power demand.

Calculation result based on total power will be displayed here.

Calculation by Equipment

If you do not know the total power value, you can estimate the required connection capacity by selecting the equipment used on the boat.

Equipment power values are approximate averages. The calculation considers typical continuous, intermittent and user-controlled load behaviour.
