AC Selector Switch

edit

The role of the selector switch is to select the source of AC power for the vessel and provide an "OFF" position to allow the isolation of the AC source as a safety feature to allow maintenance on the vessel electrics. In Australia and New Zealand the dockside power source is 240 volt / 15 amps. The majority of vessels have one single phase shore power input available to power the vessel when at the dock. When selected, the shore power inlet provides power to all vessel circuits. Larger vessels may require two shore power inlets that can share the vessel load. Power away from the dock can be sourced from either an inverter (using battery power) or an on-board generator set.
