ABSTRACT:
A power distribution system consists of an inverter means providing power to a plurality of separate outputs, with each separate output being protected by its own individual overload protection means. In case more than a pre-determined rate of power has been drawn from one of these separate outputs for longer than a pre-determined time, the associated individual overload protection means acts to remove the power from this particular output--without affecting the other outputs. However, if for some reason the individual overload protection means for that particular output fails to operate within the pre-determined time, a second overload protection means operates to disable the inverter, thereby to remove power from all the separate outputs.
