ABSTRACT:
A power system including a power transfer device that prevents a common load from at once being powered by a main and auxiliary power source, and eliminates any possibility of back feeding the main power source from the auxiliary power source. First and second circuit breakers are mounted side by side in reversely positioned relationship and have handles joined by a coupler, so that movement of the coupler in either direction opens one circuit breaker and closes the other one.
