Abstract
A power distribution system is provided which includes: a plurality of power outlets connected to the supply conductors of the system and enabling the connection of a corresponding plurality of electrical loads to the system; and a control unit connected by control conductors to the power outlets and arranged to monitor both the power suppliable by the system and the power required by the electrical loads for their operation. Each power outlet includes a switching arrangement with two operating states. In its first state, the switching arrangement enables a load connected to the power outlet to be measured by the control unit, this switching arrangement being thereafter switched into its second state by the said control unit to enable the load to be supplied with the power required for its operation only if this power does not exceed the yet-unused electric power capacity of the system. In one embodiment, each power outlet is arranged to disconnect its associated load on command by the control unit when the system is at the point of becoming overloaded.
