Abstract:
An arrangement comprising:a building having plural rooms and a main power distribution system whereby ordinary power line voltage from an ordinary electric utility power line is provided by way of a first set of power distribution wires to a first type of electrical load and/or power outlet located in each of at least two of the rooms; said power line voltage suffering from occasional periods of interruption; andauxiliary power distribution system having an auxiliary source of power and providing an auxiliary voltage by way of a second set of power distribution wires to a second type of electrical load and/or power outlet located in each of at least two of the rooms; the auxiliary voltage being provided during said periods of interruption as well as during other times; the second type of electrical load and/or outlet being different from the first type of electrical load and/or outlet; the auxiliary power distribution system is further characterized by including: (i) a power supply having a pair of output terminals operative to supply a Volt-Ampere output; (ii) the Volt-Ampere output extractable from the output terminals being manifestly prevented by a first current-limiting means from exceeding a first pre-determined level; and (iii) the magnitude of any current drawn from the output terminals being limited by a second current-limiting means from exceeding a second predetermined level; the second pre-determined level being different from the first pre-determined level.
