Superyacht Galley Electrical Power Requirements

Why Galley Power Requirements Matter

The galley is one of the highest electrical loads aboard any superyacht. Getting the calculation right at specification stage costs nothing. Getting it wrong costs a great deal.

Connected Load vs Demand Load

The connected load is the sum of rated power of every galley appliance. The demand load is what the system needs at peak usage — never the same number. Apply a diversity factor of 0.65–0.75 to arrive at the design demand load.

Single Phase vs Three Phase

Large equipment — combi-ovens above 6kW, passthrough dishwashers, blast chillers — typically requires three-phase 400V supply. Confirm the power specification of every item before finalising the distribution design.

Typical Power Requirements

DC Power for At-Anchor Operation

Refrigeration (Dometic CoolMatic) and induction cooking (inverter-compatible) are practical DC options. Combi-ovens and dishwashers at full load are generally not practical on DC power — design your at-anchor power budget accordingly.
