摘要： A system and apparatus for selectively connecting one of a plurality of sources of electrical power to a load. Apparatus is furnished to be plugged in intermediate an electrical watt hour meter and the meter receptacle normally provided in a typical electrical power utilization system that is usually designed to handle a single primary source of power. The apparatus provides for selective connection of the load distribution center to the utility power line or to another source of power which might reasonably be termed an auxiliary power source. The apparatus may easily be made to be tamper proof by the inclusion of appropriate locking seals. Further provision is made for manual switching or fully automatic operation including the energization of an auxiliary source of power and connection of the auxiliary source to the input terminals of the load distribution center. Suitable devices for sensing the existence of voltage are included to provide signals indicative of a need for selectively switching the input terminals of the load distribution center between one source of power or another.
