Claim Text:
1. A three phase to single phase automatic transfer switch for providing power to at least one single phase power load from one of a primary and a secondary source of three phase power, the automatic transfer switch comprising: a. three pairs of switches, wherein each pair of switches is connectable to the primary and the secondary sources of three phase power, wherein each switch operates in unison with the other switch within its pair, wherein each pair of switches is connectable to a different one of the at least one single phase power load, and wherein each pair of switches is operable independently of the other pairs of switches; and b. one or more controller in communication with each of the pairs of switches, the controller configured so that, when power from the primary source of three phase power is lost or degraded, the controller connects each pair of switches independently of each of the other pairs of switches from the primary to the secondary source of three phase power.
